Hiromasa Urakawa has become the second boxer to die from brain injuries sustained at the same event in Tokyo.
The World Boxing Organisation (WBO) announced the death of Japanese boxer Urakawa at the age of 28 on Sunday following a bout with Yoji Saito on August 2.
It occurred days after Shigetoshi Kotari, who fought out a draw with Yamato Hata on the same card in Tokyo, died due to injuries to his brain.
“The WBO mourns the passing of Japanese boxer Hiromasa Urakawa, who tragically succumbed to injuries sustained during his fight against Yoji Saito on August 2 at Korakuen Hall in Tokyo,” a WBO statement read.
“This heartbreaking news comes just days after the passing of Shigetoshi Kotari, who died from injuries suffered in his fight on the same card.
“We extend our deepest condolences to the families, friends, and the Japanese boxing community during this incredibly difficult time.”
Lightweight Urakawa fought 14 times as a professional (10-4, 7KOs), while Tokyo featherweight Kotari contested 12 bouts (8-2-2, 5KOs).
The Japanese Boxing Commission has since announced all Oriental and Pacific Boxing Federation title fights will be reduced from 12 rounds to 10.
Convert Voyager speed to AU per year (digit-by-digit)
Seconds per year = 86,400 × 365.25 = 31,557,600 s.
Distance per year = 17 km/s × 31,557,600 s = 536,479,200 km/year.
Convert to AU: 536,479,200 km ÷ 149,597,870.7 km/AU ≈ 3.586 AU/year.
So Voyager 1 travels about 3.6 AU per year.
Now the times for different Oort Cloud radii
(We divide distance in AU by 3.586 AU/year to get years.)
If the feature is at 1,000 AU: Time = 1,000 ÷ 3.586 ≈ 279 years. (This is roughly where a few sources place an inner Oort-like region in some estimates — hence the ~300-year figure.)
If the inner Oort Cloud (Hills cloud) is at 2,000 AU: Time = 2,000 ÷ 3.586 ≈ 558 years.
If the outer edge is at 100,000 AU: Time = 100,000 ÷ 3.586 ≈ 27,900 years (≈ 28,000 years). Many popular summaries round that to ~30,000 years, which is the figure you saw earlier for Voyager passing beyond the outer edge of the Oort Cloud.
At least 538 people have lost their lives in traffic accidents across Karachi in the first seven months of 2025, with heavy vehicles responsible for a significant share of the fatalities, official data shows.
According to latest figures, traffic accidents involving trucks claimed 60 lives, trailers 48, water tankers 44, buses 25, dumpers 22, minibuses 11, coaches and oil tankers six each, pickups 15, jeeps five, motorcycle rickshaws 12, and cars 58. Motorcycles were involved in accidents that left 88 people dead, while unidentified vehicles accounted for 103 fatalities.
The victims included 274 motorcyclists, 179 pedestrians, 51 women, and 68 children.
District-wise, Malir recorded the highest number of deaths (174), followed by West and Keamari (136), Central (75), East (52), Korangi (52), South (44), and City (3).
The latest tragedy occurred on Rashid Minhas Road near Lucky One Mall, where a speeding dumper rammed into a motorcycle, killing 22-year-old Mahnoor and her 14-year-old brother Ali Raza. Their father sustained serious injuries and is under treatment.
The incident sparked unrest, with an angry mob torching seven dumper trucks and assaulting the driver involved, who was later handed over to police. SSP Central said the driver had been taken into custody, while over 10 people were detained for the violence.
Rescue 1122 confirmed the blaze had been extinguished and cooling operations completed. Karachi Traffic Police reported that both tracks of the Al-Asif–Hyderabad route were closed for hours, with traffic diverted via Total Petrol Pump.
In retaliation, the Dumper Drivers Association blocked the Super Highway near Sohrab Goth and threatened to extend the protest to the National Highway.
Sindh Governor Kamran Tessori expressed sorrow over the siblings’ deaths, called for strict action against those responsible, and urged citizens to refrain from taking the law into their own hands.
The tuning gurus over at Brabus have tackled the AMG GT 63 S E Performance more than once, but this is the first time they ended up with a monster devouring supercars for breakfast.
The stock 4.0-liter twin-turbo V8 was stroked out to 4.5 liters of displacement and outfitted with larger turbos. An aluminum crankshaft, forged connecting rods and a custom exhaust system also found their way into the build. When all was said and done, the car slammed the transmission with 1,000 PS (986 hp / 735 kW) and 1,820 Nm (1,342 lb-ft) of torque. Brabus actually had to clamp it at 1,620 Nm (1,195 lb-ft) for safety reasons.
The electric motor stayed as is. The tuner claims the car now accelerates to 100 km/h (62 mph) in 2.6 seconds, doubles that speed in 9.5 seconds and triples it in 23.6 seconds. It only hits its limit at 320 km/h (199 mph), and that’s electronically capped, too.
The full tuning package includes an optimized aero kit, 10-spoke staggered wheels (21” front, 22” rear) and a 20mm (0.8”) suspension lowering kit. The interior of the show car seen here mostly uses black leather with vivid red accents and carbon fiber details, but Brabus usually allows its clients extensive personalization.
If you want a Brabus 1000 for yourself, look around for a spare €445,900 at the minimum ($518,400).
I’ve done everything I can think of to improve my mindfulness. I’ve tried countless meditation apps and breathing exercises to stay in the present, and I’m always working on improving my mental health.
What helps me stay grounded has nothing to do with any of that. It’s an app for identifying birds.
Cornell Lab of Ornithology’s Merlin Bird ID launched in 2014 to help people identify the birds they see and hear. Thanks to eBird, the world’s largest database of bird sounds and photos based on 800 million global sightings, the app allows you to record a bird, answer a series of questions or upload a photo to name your winged friend. Or you can simply use the app to explore the different birds in your area, no matter where you are in the world, and even if you’re offline.
The app’s homepage, with three avenues for identification.

One of my favorite features of Merlin Bird ID is that you can use it to keep track of your bird sightings and, like an IRL Pokemon GO, “collect ’em all.”
The first time I used the app, I sat out on my balcony, clicked the green “Sound” button and watched as the app identified the birds chirping and singing in all directions. You can see the different sound frequencies as they appear on a real-time spectrogram, a visual representation of the audio world. The next time I checked the clock, I was shocked to see that an hour had passed. Then, I dug out my binoculars and let even more time fly.

As any Merlin Bird IDer knows, there is no thrill quite like pressing the “This is my bird” button for the first time, and it never gets old. From there, you can record your location. The app, in turn, will save your report to improve its performance.
Before long, I had different bird sounds memorized. In the morning, I would wake to the sound of a California Towhee’s alarm-like and frankly, yes, annoying cheeping from a tree outside my window right as the sun started to rise. On walks around my neighborhood, I’d auditorially part the sound of cars and distant construction to hear the melody of House Finches mixed with staccato chirps of Lesser Goldfinches and the droning coos from a pair of Mourning Doves religiously stationed on electrical wires. It was the song that had been the soundtrack of my world, but I hadn’t noticed until now.
By sight, I’d recognize Red-Whiskered Bulbuls with their black crests and fire engine cheeks, a blush color waiting to be replicated in powder form. Black Phoebes made themselves known with their fluffy soot-black heads, statue stillness and ivory bellies. At the hummingbird feeder on my balcony, there is a never-ending line of customers with iridescent throats in sunset colors: Anna’s Hummingbirds (my favorite, as you might guess), Allen’s and even the uncommon Rufous, who spend all day fighting over sugar water when not watching the feeder from their magnolia tree perches.
A customer at our feeder. I think they’re an Allen’s Hummingbird.

What’s most thrilling is when the Merlin Bird app hears a bird that you can’t see, making it feel as though it’s your mission to treasure hunt your way to it. This is often a lesson in patience, as it may take you several tries to find the songbird you seek. Recently, while sitting in a new-to-me park, the app told me a Mountain Chickadee was nearby and I spent the next 45 minutes trying to spot it with my binoculars. It ended up on a branch directly above my head, and when I got up to leave, it flew down right by my face as if in on the joke that it was there the whole time.
I’ve yet to find the Red-Winged Blackbird who always seems to be just out of reach, no matter where I am in my city, but I console myself with the seemingly all-knowing flock of Common Ravens (also unjustly called an “unkindness”) evermore on my street and the surprising number of noises they can produce.
Birds I haven’t spotted … yet.

I also often listen back to the comforting hoo-hoos of a Great Horned Owl singing a 9:30 p.m. lullaby right before the start of spring. I like time-travelling to these moments, though I have come across some retrospectively hilarious conversations I unintentionally recorded in between birdsong. With that being said, Merlin Bird ID does save your audio recordings but only on your device in the app. To share the recordings with eBird, you have to manually export and upload them.
I now seek out unexplored wooded spaces to meet new feathered friends, an excuse for forest bathing, which has led me to see the shade of blue unique to a Ruddy Duck’s bill. After a rainstorm, I’ve come across a group of Acorn Woodpeckers with impressive red mohawks excitedly pecking wet, softened wood while calling to each other. Like a conversation between punk besties over dinner. My area is known for its large flocks of Amazon parrots (and their persistent screeches), whom I’ve now had the pleasure of seeing up close as they use their light yellow bills to climb trees and collect their berries. And once, just once, I caught the backside of a Yellow Warbler in a nearby watershed park.

Because of this app, I’ve spent more time listening to the world around me and less time in my own head, bobbing between the past and future. I’ve found myself surrounded by and in conversation with nature more than ever before. It may be the closest thing we have to magic here on Earth. Now, perhaps that is the key to grounding yourself: Getting your butt on the ground and taking the time to listen to those who are singing around you.
A simple way to distinguish a spacecraft from a rock is through its large non-gravitational acceleration. A natural icy rock like a comet is propelled by its mass loss. That mass loss can be observed through the cometary plume of gas and dust that surrounds the comet’s nucleus. By measuring the rate of mass loss and the characteristic ejection speed of gas and dust, one can calculate the rate of momentum change per unit time, or the non-gravitational force exerted on the nucleus. Since the evaporation occurs on the dayside of the rock which is warmed up by the virtue of it facing the Sun, this force pushes the comet’s nucleus away from the Sun. At a large enough distance, typically a few times the Earth-Sun separation, the surface of the nucleus is not warmed enough by sunlight to release volatile ices and dust and the cometary activity diminishes.
A technological object, on the other hand, could operate an engine and maneuver independently of the Sun. It can be propelled towards the Sun or any planet of interest and exhibit a non-gravitational acceleration of arbitrary magnitude or direction. Observing non-gravitational maneuvers could shift the ranking of an interstellar object on the “Loeb scale”, from `0’ — the default value for a natural comet to `10’ — a definitely artificial object.
Given this perspective, it is of great interest to measure the acceleration of the new interstellar object 3I/ATLAS along its path through the Solar System and check whether it shows any deviation from the expected trajectory, as dictated by gravity alone. If 3I/ATLAS will not continue along its expected path after its closest approach to the Sun on October 29, 2025, then the stock market might crash from worries about an alien tech visitation.
If 3I/ATLAS is a natural comet, what is its expected non-gravitational acceleration?
The recent imaging of 3I/ATLAS by the Hubble Space Telescope shows a glow ahead of the object but no bright tail of gas and dust behind it — as often observed for comets (see related paper here). In addition, spectroscopic measurements show no evidence for molecular or atomic gas accompanying this glow (see related papers here, here and here, as well as the discussion about water ice here). A natural interpretation of these anomalies is that 3I/ATLAS is a dust-rich comet that releases little gas, but mostly large dust particles which are not pushed back by Solar radiation pressure or the Solar wind because of their small surface-to-mass ratio. In this case, we can calculate the expected non-gravitational acceleration of this comet from the observed plume of dust leading it.
A detailed analysis of the observed glow ahead of 3I/ATLAS (see related paper here) suggests a mass loss rate of up to 60 kilograms per second for dust particles of 100 micron size (where a micron is a millionth of a meter) and an ejection speed of ~2 meters per second in the direction of the Sun. The estimated mass loss rate drops to 6 kilograms per second and an ejection speed of 20 meters per second for 1-micron particles. Since the non-gravitational force exerted on 3I/ATLAS equals the mass loss rate times the ejection speed, its value is the same in both cases and does not depend on the assumed size of the ejected dust particles.
The brightness distribution in the glow preceding 3I/ATLAS was also used to set limits on the diameter of its nucleus, inferred to be in the range of 0.32–5.6 kilometers. This implies that the nucleus mass is in the range of 30 billion to 200 trillion kilograms. Applying the resulting non-gravitational force to this mass leads to a non-gravitational acceleration in the range of 3×10^{-14} to 2×10^{-10} AU per day squared, where AU stands for Astronomical Unit which is defined as the Earth-Sun separation. This non-gravitational acceleration range is equivalent to values between 6×10^{-11} and 4×10^{-7} centimeters per second squared, in the direction away from the Sun.
For comparison, the first interstellar object 1I/`Oumuamua exhibited on October 25, 2017 a non-gravitational acceleration of 1.4×10^{-7} AU per day squared, equivalent to 2.7×10^{-4} centimeters per second squared (see related data here). This is larger than the expected non-gravitational acceleration of 3I/ATLAS by a huge factor, ranging between a thousand and 10 million. If 1I/`Oumuamua was a familiar comet, it had to lose about a tenth of its mass during its passage close to the Sun. But despite its large non-gravitational acceleration, 1I/`Oumuamua did not display any cometary evaporation (see observational data here), making its large non-gravitational acceleration a major anomaly concerning its nature (as argued in my related paper here).
If 3I/ATLAS is a natural comet, its outgassing may intensify as it gets closer to the Sun. A measurement of the expected non-gravitational from its cometary activity would confirm its natural origin. A paper that I wrote with my student, Sriram Elango, before the discovery of 3I/ATLAS, showed that localization data from the Webb telescope in combination with terrestrial telescopes can pinpoint the trajectory of an interstellar object to unprecedented precision using parallax, since the Webb telescope is located 1.5 million kilometers away from Earth at the L2 Lagrange point. A major deviation of the measured non-gravitational acceleration from the expected range for a comet, would suggest that 3I/ATLAS might be propelled technologically.
For now, we cannot assess with any confidence whether 3I/ATLAS is a natural dust-rich comet with no gaseous tail on an extremely rare trajectory, or perhaps a technological object on a path that was designed to align with the ecliptic plane of the planets around the Sun. All we know is that 3I/ATLAS exhibits a rare (0.2% probability) alignment of its retrograde path with the ecliptic plane to within 5 degrees, and its arrival time along this path is perfectly suited for a close encounter with Mars, Venus and Jupiter (with a 0.0005% probability, as discussed here). These coincidences would allow a mothership to release mini-probes that will reach planets as they move into the mini-probes’ orbits, taking advantage of the mothership’s retrograde motion. Since 3I/ATLAS will hide behind the Sun at its perihelion on October 29, 2025, we will not be able to observe whether it releases any mini-probes into Earth’s orbit.
Exquisite measurements of the non-gravitational acceleration of 3I/ATLAS would provide an important clue about its nature. The verdict will not be decided by debates on social media, but rather by accurate measurements of instruments. This is the same as the video assisted referee (VAR) protocol used by FIFA to decide whether a goal was scored under controversial circumstances. FIFA rules by viewing data recorded by cameras, rather than by asking soccer players or the goalkeeper for their opinions. We all know that the Earth moved around the Sun for 4.54 billion years before the Vatican placed Galileo Galilei in house arrest for suggesting that. Whether 3I/ATLAS is natural or technological in origin has nothing to do with popular opinions on Earth.

Jessie J admits she ‘sobbed’ over post-surgery scars
Jessie J just shared a heartbreaking moment where she “sobbed” over her post-surgery scars.
The 37-year-old underwent breast cancer surgery to remove a lump that had developed after revealing the doctors had caught it “early.”
Now in a raw and personal interview with The Sunday Times‘ CultureMagazine, Jessie shared that after having surgery, she broke down in tears while looking at her scars.
She said: “The other night. Mum was massaging my b**b for me, because I can’t touch the scars. And I started sobbing, ‘I can’t believe this has happened.’ She was like, ‘I wish it was me,’ and then I’m crying, she’s crying… I’m so glad it’s not her.”
The Bang Bang singer also added that she will be needing more surgery in the future but she’s still eager to return to the music scene, with her upcoming song, Believe In Magic set to be released on August 29.
“People think, once you’ve got the all-clear, now it’s done. But I’ve got another surgery [to improve the symmetry of her implant with her other breast] and I need to heal, so I have to figure out the rest of this year,” Jessie J revealed to the outlet.
The pop star, who is a mother to son Sky, also spoke of how he has been the “light of her life” during her cancer battle.
This comes after Jessie J shared in an Instagram update, earlier this week, that she would be undergoing more surgery, writing in her caption: “I can rest, parent AND release new music. I didn’t leave a major label after 18 years to be scared to re write the rules to fit around my life / health and just make it realistic on what I can deliver in all roles in my life. Another surgery needed this year. I can do it.”
As the legal troubles of Malik Riaz deepen, one question is on everyone’s mind: Will prices in Bahria Town collapse, or can the real estate giant weather the storm and emerge unscathed?
The answer is not simple, it depends on several factors. For now, prices in Bahria Town have not crashed, despite social media rumors of a more than 50 percent drop in certain areas. However, market activity remains sluggish and is likely to stay that way until the situation becomes clearer.
What Sparked the Panic?
The recent auction of Bahria Town properties by the National Accountability Bureau (NAB), along with a stark statement from Malik Riaz, has rattled investor confidence.
Following NAB’s announcement, Riaz warned that the situation had reached a point where Bahria Town might be forced to shut down all operations across Pakistan.
“Our cash flow has been completely destroyed. It has become impossible to provide daily services, and we are unable to pay the salaries of our tens of thousands of staff. The situation has reached a point where we are being forced to completely shut down all Bahria Town activities across Pakistan,” he said in a statement.
Current Market Situation
In a recent report, BBC Urdu quoted individuals connected to the real estate market who expressed serious concern over the developments.
One property dealer said that tensions between the government and Malik Riaz had already dampened buying and selling for a long time. He warned that if Bahria Town’s offices close, property transfers for houses and plots would come to a complete standstill until an alternative system is put in place.
Another realtor told the publication that in recent months, the situation in Bahria Town projects has prompted many investors to liquidate their holdings and exit.
What’s Next for Bahria Town?
With multiple inquiries and legal battles ongoing, uncertainty continues to overshadow Bahria Town’s future. Under such conditions, new investors are unlikely to step in, while anxious existing investors may rush to offload their properties.
In the short term, there is little positive news for Bahria Town or its investors. However, depending on the outcomes of ongoing cases, the situation could improve in the long run. Still, whether the once-dominant Bahria Town can reclaim its position as Pakistan’s top real estate investment choice remains to be seen.
This is a general assessment of the situation and not investment advice.
China’s former defence attache in South Asia Cheng Xizhong on Sunday spurned India’s much-delayed claim that it had shot down six Pakistani aircraft during the May conflict, terming it “self-amusement”.
Having faced international coverage of its own craft being downed by Pakistan and scathing criticism from the opposition, India’s Air Chief Marshal Amar Preet Singh — three months after the conflict — claimed yesterday that his country had shot down five Pakistani fighter jets and one other military aircraft during those clashes.
While Pakistan had already denied that India downed any of its aircraft, Defence Minister Khawaja Asif swiftly rubbished Singh’s “belated assertions” yesterday.
Commenting on the matter today, Cheng said India’s allegations lacked strong evidence and have been “widely questioned by the international community, being considered groundless”, the Associated Press of Pakistan reported.
Singh’s remarks were “comical, implausible and unconvincing”. “We may call it self-amusement,” he said in a statement.
Pakistan said it downed six Indian planes during the conflict. India’s highest-ranking general has also acknowledged that its forces suffered losses in the air, but denied losing six aircraft.
“The Indian side has not presented any evidence, such as photos of the wreckage of the fighter jets, radar monitoring data, etc, while the Pakistani side had previously presented a large amount of relevant evidence of shooting down the Indian fighter jets,” Cheng noted.
The defence expert believed that everything should be based on sufficient evidence.
He highlighted that now, more than three months have passed since the India-Pakistan clash. New Delhi has never produced any evidence to prove that it had shot down Pakistani fighter jets, Cheng highlighted.
“In contrast, the Pakistan side immediately provided a detailed technical report to international media after the clash ended,” he added.
The Chinese expert also cited “confirmations from world leaders, senior Indian politicians, and foreign intelligence assessments that India suffered heavy losses of multiple aircraft”.
“It is thus evident that no Pakistani fighter jet was hit or destroyed by the Indian side. On the contrary, the Pakistani side shot down six Indian fighter jets and destroyed S-400 air defence positions, among other achievements, which is an indisputable fact,” he added.
Professor Cheng is currently a senior research fellow at the Chinese think tank Charhar Institute and has also served as a former United Nations senior military observer, according to CGTN.
In his claims yesterday, the Indian Air Force (IAF) chief did not mention the type of Pakistan’s fighter jets that he insisted were taken down.
Asif, responding to Singh, stated that “not a single Pakistani aircraft was hit or destroyed” by India. He declared that Pakistan took out six Indian jets, S-400 air defence batteries and unmanned aircraft of India while “swiftly putting several Indian airbases out of action”.
Former envoy to the United States Dr Maleeha Lodhi also termed Singh’s claim “laughable”, quipping that it took him “several months to count the planes to make this ridiculous assertion!”
Criticism also echoed from within India. Congress spokesperson Pawan Khera cast his doubts, saying: “The question we have after today’s information … when we had such a strong army and we were advancing, then under whose pressure did you stop Operation Sindoor?”
New Delhi had previously claimed it had downed “a few planes”, refusing to go into the specifics of it. US President Donald Trump has echoed the figure of “five jets” shot down during the military confrontation, albeit without specifying which side’s craft he was referring to.
India’s loss of jets affirmed globally
France’s air chief, General Jerome Bellanger, has previously said that he has seen evidence of the loss of three Indian fighters, including a Rafale. The IAF has not commented on those claims.
Days after the air combat, The Washington Post, based on visual evidence analysed by experts, reported that at least two French-made Indian fighter aircraft were shot down by the Pakistan Air Force (PAF).
India’s defence attache to Indonesia, Indian Navy Captain Shiv Kumar, acknowledged in June that the PAF downed Indian fighters, according to The Wire.
India’s intelligence failure was central to the hour-long air battle with Pakistan, which led to the downing of Rafale aircraft by the PAF’s J-10 fighters using PL-15 missiles, according to a Reuters report.
In a press briefing two days after the May 7 air combat, Air Vice Marshal (AVM) Aurangzeb Ahmed, the deputy chief of operations of Pakistan Air Force (PAF), shared the locations where five Indian jets were downed — four along the Line of Control and one near Bathinda in northwest India. He also disclosed that one of the Indian jets was downed by Pakistani air defence systems.
According to a Dawn report, which cited PAF officials, India’s three Rafales, one Su-30MKI and one MiG-29 were downed within a 40-minute span. Not a single Pakistani jet crossed the border or engaged in close combat.
Describing the engagement as a textbook case of modern aerial warfare, AVM Aurangzeb had said Pakistan had tracked over 70 Indian aircraft — including 14 Rafales — using its Electromagnetic Operational Environment and responded with a concentrated and pre-planned defensive counter-air strategy.
“Our side deployed 42 high-tech aircraft,” the PAF officer said. He noted that while India remained on its side of the border and launched air-to-ground weapons, Pakistani defences detected and engaged the threats instantly.
OpenAI’s new models run efficiently on minimal hardware, but haven’t been independently tested for workloads
The models are designed for edge use cases where full-scale infrastructure isn’t always available
Apache 2.0 licensing may encourage broader experimentation in regions with strict data requirements
OpenAI has released two open-weight models, gpt-oss-120B and gpt-oss-20B, positioning them as direct challengers to offerings like DeepSeek-R1 and other large language learning models (LLMs) currently shaping the AI ecosystem.
These models are now available on AWS through its Amazon Bedrock and Amazon SageMaker AI platforms.
This marks OpenAI’s entry into the open-weight model segment, a space that until now has been dominated by competitors such as Mistral AI and Meta.
OpenAI and AWS
The gpt-oss-120B model runs on a single 80 GB GPU, while the 20B version targets edge environments with only 16 GB of memory required.
OpenAI claims both models deliver strong reasoning performance, matching or exceeding its o4-mini model on key benchmarks.
However, external evaluations are not yet available, leaving actual performance across varied workloads open to scrutiny.
What distinguishes these models is not only their size, but also the license.

Released under Apache 2.0, they are intended to lower access barriers and support broader AI development, particularly in high-security or resource-limited environments.
According to OpenAI, this move aligns with its broader mission to make artificial intelligence tools more widely usable across industries and geographies.
On AWS, the models are integrated into enterprise infrastructure via Amazon Bedrock AgentCore, enabling the creation of AI agents capable of performing complex workflows.
OpenAI suggests these models are suitable for tasks like code generation, scientific reasoning, and multi-step problem-solving, especially where adjustable reasoning and chain-of-thought outputs are required.
Their 128K context window also supports longer interactions, such as document analysis or technical support tasks.
The models also integrate with developer tooling, supporting platforms like vLLM, llama.cpp, and Hugging Face.
With features like Guardrails and upcoming support for custom model import and knowledge bases, OpenAI and AWS are pitching this as a developer-ready foundation for building scalable AI applications.
Still, the release feels partly strategic, positioning OpenAI as a key player in open model infrastructure, while also tethering its technology more closely to Amazon Web Services, a dominant force in cloud computing.
