Microsoft
Foundry Fine-Tuning is updated to reflect a complete redesign of Foundry’s UI,
delivering an agent-first experience for developers and data scientists. The
new interface streamlines model creation, evaluation, and deployment,
integrates with VS Code, and modernizes navigation. With unified workflows and
enhanced usability, enterprises can accelerate AI development, reduce friction,
and future-proof their agent ecosystem. Public preview launches with
full migration planned after July 2025. As a part of this update, Microsoft
Foundry now supports Reinforcement Fine-Tuning (RFT) for GPT-5, enabling
developers to adapt large language models for specialized, context-aware
applications. This update empowers teams to optimize model performance for
unique business scenarios, driving innovation and improved outcomes.
Microsoft
Foundry now additionally supports fine-tuning for non-OpenAI models like
Mistral using the same APIs, UI, and workflows as GPT-4.1. Developers can
fine-tune, deploy, and manage models with full parity across training and
deployment, benefiting from quota management and developer tier hosting. This
unified experience lowers costs, accelerates iteration, and simplifies
production deployment for custom AI solutions.
