The development landscape has just undergone a dramatic shift. Microsoft’s VS Code team has taken a bold step toward democratizing AI-powered coding by open-sourcing its GitHub Copilot Chat extension under the MIT license. This milestone represents more than just another code release; it’s a fundamental reimagining of how AI tools should be developed and deployed in the developer ecosystem.

Breaking Down Barriers to Innovation

The decision to make VS Code an open-source AI editor addresses a growing concern in the developer community: The black-box nature of AI coding assistants. Until now, developers have been using powerful AI tools without understanding their inner workings, from prompt engineering techniques to context handling strategies. This transparency gap has hindered innovation, making it challenging for developers to fully optimize their AI-assisted workflows.

By open-sourcing the Copilot Chat extension, Microsoft has lifted the veil on these critical components. Developers can now examine exactly how agent mode functions, understand what context gets sent to large language models and study the prompt engineering strategies that make these tools effective. This level of transparency transforms AI coding from a mysterious process into something developers can understand, modify, and improve.

Community-Driven AI Development

The open source approach leverages the same community dynamics that made VS Code itself a success. Over the past decade, VS Code has evolved from a Microsoft project into a community-driven platform, with thousands of extensions and contributions from developers worldwide. Now, the VS Code team is applying this proven model to AI functionality.

This community-centric approach promises to accelerate innovation in ways closed development cannot match. When developers can see precisely how AI features work, they can identify areas for improvement, fix bugs, and adapt functionality to meet specific needs. The collective intelligence of the open-source community often surpasses what any single organization can achieve, regardless of its resources.

Practical Benefits for Development Teams

The immediate practical implications are significant. Development teams can now audit AI functionality to ensure it meets their security and compliance requirements. Organizations with strict data governance policies can examine exactly what information is transmitted to language models and modify their behavior accordingly.

For individual developers, this transparency enables more effective prompt engineering and a better understanding of AI behavior. Instead of treating AI coding assistants as unpredictable tools, developers can study successful patterns and apply them more systematically. The ability to examine system prompts and implementation details provides insights that can improve AI-assisted productivity across entire teams.

“This marks Microsoft’s follow-through to open source GitHub Copilot Chat, announced at Microsoft Build 2025,” said Mitch Ashley, VP practice lead of software lifecycle engineering at The Futurum Group. “GitHub Copilot Chat serves as the direct interface between the developer and the underlying AI code generation and agent capabilities available through VS Code and GitHub Copilot Agent. This transparency helps build trust with developers as AI takes on increased workloads for developers.”

Technical Architecture and Integration Strategy

The VS Code team’s technical approach demonstrates thoughtful planning for long-term sustainability. Rather than keeping AI functionality in a separate extension indefinitely, they plan to integrate components directly into VS Code’s core. This integration strategy ensures that AI becomes a first-class citizen in the editor, rather than an afterthought.

The decision to maintain issue tracking in the central VS Code repository further reinforces this integration philosophy. It signals that AI functionality isn’t a side project but a central part of VS Code’s future direction. This architectural approach provides a foundation for more sophisticated AI features while maintaining the editor’s performance and reliability standards.

Industry Implications and Future Outlook

This move represents a broader shift in how technology companies approach AI development. As AI becomes integral to software development workflows, the traditional closed-source model creates dependencies that many organizations find uncomfortable. Microsoft’s decision to embrace transparency could pressure other AI tool providers to follow suit.

The implications extend beyond individual developer productivity. Educational institutions can now use real AI implementations to teach prompt engineering and AI integration techniques. Researchers gain access to production-quality AI coding systems for academic study. Security researchers can audit AI tools for potential vulnerabilities or biases.

Challenges and Considerations

Open-sourcing AI functionality presents its challenges. The VS Code team must strike a balance between transparency, performance optimization and consistency in user experience. Managing community contributions while maintaining code quality requires significant investment in review processes and documentation.

The partial approach, open-sourcing chat functionality while keeping inline completions closed, reflects these complexities. This staged rollout allows the team to learn from community feedback before expanding the open-source scope to more complex features.

The Path Forward

The VS Code team’s roadmap demonstrates a commitment to gradually expanding open-source AI functionality. Plans to provide inline completion capabilities through the open-source extension demonstrate long-term dedication to the transparency vision. A partnership with the broader open-source AI community suggests that the success of this initiative depends on ecosystem-wide collaboration.

This milestone represents more than a technical achievement; it’s a fundamental shift toward more democratic, transparent and community-driven AI development. As artificial intelligence reshapes software development, having open, auditable and modifiable AI tools becomes increasingly important for maintaining developer agency and innovation.

The future of coding is undoubtedly AI-assisted, but Microsoft’s approach ensures that the future remains open, transparent and community-controlled. For developers who value understanding their tools and shaping their evolution, this represents a significant step toward a more empowering development environment.

Porsche is expanding its 911 series with three models. The latest edition of the Carrera 4S is being launched as a coupé and cabriolet. Together with the Targa 4S, they expand the model lineup beneath the significantly more powerful GTS models. This premiere doubles the number of all-wheel-drive variants of the 911, bringing the total to six. Its extensively revised powertrain gives the all-wheel-drive sports car a significant boost in emotionality compared to its predecessor models. Additional individualisation options and an expanded list of standard equipment round off the overall package.

About half of all customers who choose the S variants of the 911 opt for all-wheel drive, and for good reason: it ensures maximum traction in poor weather. Particularly in regions with changeable climates or demanding road conditions, the 911 with all-wheel drive inspires additional confidence behind the wheel. Like all the all-wheel-drive models of the 911, the S variants are also designed with rear-biased driving dynamics. If required, the Porsche Traction Management (PTM) system provides more drive torque to the front axle, thereby increasing traction and driving stability. As with predecessor models, the clutch assembly in the front differential, which is still water-cooled, is controlled electromechanically. Only the gear ratio has been slightly adjusted. The 911 Targa body style is available exclusively with all-wheel drive.

Improved driving performance

The new all-wheel drive variants of the 911 adopt the upgraded drive system of the Carrera S. Its 3.0-litre twin-turbo six-cylinder boxer engine produces 353 kW (480 PS, 911 Carrera S: Fuel consumption* combined (WLTP) 10.8 – 10.3 l/100 km, CO₂ emissions* combined (WLTP) 244 – 232 g/km, CO₂ class G , CO₂ class weighted combined G ). That is 22 kW (30 PS) more than in the predecessor model. This increase in performance is partly due to the optimised intercooler system, the design of which is carried over from the 911 Turbo. An eight-speed Porsche dual-clutch transmission (PDK) transmits power to all four wheels. The 911 Carrera 4S Coupé accelerates from 0 to 100 km/h in 3.3 seconds (with Sport Chrono Package) and to a top speed of 308 km/h. 

Sixty years of the 911 Targa: an idea with a history

For 60 years, the 911 Targa has combined the pleasure of a convertible with the year-round comfort of a coupé. The original version of this model was Porsche’s response to discussions and concerns in the US market regarding the safety of traditional convertibles. The Targa body style made its debut in September 1965 at the IAA in Frankfurt am Main and was dubbed as the ‘safety cabriolet’.

Like so many Porsche innovations, the elegant, wide roll bar is inspired by motorsport. With a removable roof and folding rear window, the car provided safety-conscious drivers the sensation of travelling in a full convertible. Porsche derived the Targa name from the famous Sicilian endurance race, the Targa Florio.

Today, the Porsche 911 Targa is an icon in its own right, constantly further developed in terms of engineering and design over six decades. With the introduction of the 993-generation 911 Targa in 1993, there was no longer a need to remove the roof manually. Since 2006, the 911 Targa has been available exclusively with all-wheel drive.

From 2014 onwards, fully automatic roof mechanisms have been used: in 19 seconds, the coupé-like sports car is transformed into an open-top vehicle in a spectacular choreographed sequence. The glass rear window folds backwards and the roof segment folds elegantly. The wide roll bar and the wraparound rear window are a clear reminiscence of the original model. The roof module of the current Targa is available in four colours: black, blue, red and brown.

Enhanced equipment

The standard equipment has been significantly upgraded compared to the previous models. This includes 20/21-inch staggered-fitment Carrera S wheels with an updated design, Porsche Torque Vectoring Plus (PTV+) and a sports exhaust system with a distinctive sound typical of the 911.

Equipped as standard is the braking system carried over from the GTS models, with red brake callipers and 408-millimetre discs at the front and 380 mm at the rear. The 911 Targa 4S features rear-wheel steering as standard. While the Cabriolet and Targa are equipped with rear seats, Porsche delivers the coupé as a two-seater as standard. A rear seat system can be configured at no extra cost.

Porsche equips the interior of the all-wheel-drive sports car with a leather package. In addition, matrix LED headlights and wireless smartphone charging are also included as standard. Other features include electrically folding exterior mirrors with mirror surround lighting, the Light Design Package, automatically dimming interior and exterior mirrors with integrated rain sensor, and lane departure warning. A wide range of other options for individualisation are available on request, including a wide variety of colour and material combinations as well as sound, assistance and roof systems.

As reliably as the sun rises and sets, Porsche is fleshing out the 911 lineup. Following last year’s facelift, Porsche just revealed the new all-wheel drive “S” variants, Carrera 4S coupe and Cabriolet, plus Targa 4S. The headline? More power and standard equipment than their predecessors, and a healthy price increase, too.

Like the rear-drive Carrera S coupe and Cabriolet, the new all-wheel drive models get a 3.0-liter twin-turbo flat-six making 473 horsepower and 390 pound-feet of torque. The power increase is largely thanks to intercoolers from the 911 Turbo, Porsche says, and the horsepower figure matches the old Carrera GTS’s, though torque is slightly lower. As with its rear-drive siblings, the only transmission available is an eight-speed PDK dual-clutch. Porsche is, so far, limiting the manual to just the purist-aimed Carrera T and GT3.

The new 4S models also get a standard Sports Exhaust and larger brakes from the old Carrera GTS model. As before, adaptive dampers, a rear limited-slip differential, and 20/21-inch wheels are standard, while sport suspension, rear-wheel steering, the Sport Chrono package, and carbon-ceramic brakes are optional. However, the Targa 4S gets rear-steer standard.

Inside, there’s more leather trim standard than before, and the rest of the upgrades Porsche gave the 911, including somewhat controversially, a digital gauge cluster. The coupe comes standard as a two-seater now, with 2+2 seating a no-cost option, and standard on the Cabriolet and Targa. 

Porsche says in the US, around half of all 911 “S” models are all-wheel drive, so these are an important addition to the lineup. And until now, for the face-lifted model, the entry-level all-wheel drive 911 was the hybrid Carrera 4 GTS. So, these cars usefully lower the barrier of entry.

Not that they’re cheap. Preliminary pricing for the 2026 Carrera 4S coupe is $156,450—over $16,000 more than the 2024 model, though Porsche stresses this is subject to change. There’s more standard equipment and performance than before, but still, that’s a large gap. The preliminary cost for the Carrera 4S Cabriolet is $169,650 while the Targa 4S is $171,350. Not that Porsche customers will balk at these prices. Demand for new 911s seems to far outstrip supply.
