junjieli explains how the AI Toolkit v0.18.3 for VS Code brings full support for GPT-5 and GPT OSS models, providing developers with powerful AI integration and deployment features across Azure and local environments.

GPT-5 Family of Models & GPT OSS Are Now Available in AI Toolkit for VS Code

AI Toolkit v0.18.3 delivers a major milestone for developers working with AI in Visual Studio Code. This release brings:

Support for the GPT-5 family of models
Integration of OpenAI’s open-source GPT OSS models via Azure AI Foundry and ONNX Runtime

Whether you’re building cloud, edge, or local solutions, this update expands your options for performance, flexibility, and model variety.

🧠 GPT-5 Models: Integrated in AI Toolkit

You can now access the latest GPT-5 models directly from AI Toolkit, available through GitHub, Azure AI Foundry, or OpenAI APIs. Key models include:

gpt-5: Advanced reasoning for analytics, LLM orchestration, and code generation.
gpt-5-mini: Low-latency and cost-effective for real-time and resource-constrained use cases.
gpt-5-nano: Speed-optimized for Q&A and workflow automation.
gpt-5-chat (preview): Built for multi-turn conversations with persistent context, ready for agentic applications.

🧬 GPT OSS Models: Open-Source AI for Cloud and Local Use

For the first time, developers can deploy OpenAI’s open-source GPT OSS models via:

Azure AI Foundry for cloud-scale deployment
Windows AI Foundry paired with ONNX Runtime for local GPU inference.

Model Highlights

gpt-oss-120b: Text-in/text-out, open-weight, supports chain-of-thought, response formatting, and adjustable reasoning levels. Learn more
gpt-oss-20b-cuda-gpu: CUDA-optimized for local use with RTN quantization, suitable for Windows and edge deployments. Learn more
