AI Toolkit v0.18.3 is here—and it’s a major milestone. This release introduces full support for:

• The latest GPT-5 family of models


• OpenAI’s open-source models (GPT OSS) via Azure AI Foundry and ONNX Runtime

Whether you’re building in the cloud, on the edge, or experimenting locally, this update gives you more flexibility, performance, and choice than ever.

🧠 GPT-5 Models: Now in AI Toolkit

The GPT-5 model family is now fully integrated into AI Toolkit and available via GitHub, Azure AI Foundry, or OpenAI.

✨ Model Overview:

• gpt-5: Advanced reasoning for analytics, LLM orchestration, and code generation.


• gpt-5-mini: A cost-effective, low-latency model ideal for real-time agents and lightweight tools.


• gpt-5-nano:Built for speed and concise reasoning—great for retrieval, Q&A, and compact workflows.


• gpt-5-chat (preview): Enables natural, multimodal, multi-turn conversations with persistent context—perfect for agentic apps.

🧬 GPT OSS Models: Open-Source Power, Local & Cloud-Ready

For the first time, OpenAI’s open-source models (GPT OSS) are available through:

• Azure AI Foundry for cloud-scale deployment


• Windows AI Foundry with ONNX Runtime for local inference
