Introducing improvements to the fine-tuning API and expanding our custom models program
What changed
We’re adding new features to help developers have more control over fine-tuning and announcing new ways to build custom models with OpenAI.
Why it matters
A concrete addition to Practical AI: Tools, Models & Frameworks: it changes what's available to builders today rather than being general commentary.
