First-class support for OpenAI-compatible (OpenAPI-compatible) LLM providers in TanStack AI

[RadheyMugdal]

Hi 👋
TanStack AI is great,

One limitation I ran into: TanStack AI currently requires provider-specific adapters, which makes it hard to use OpenAI-compatible APIs such as OpenRouter, Together, Groq, Fireworks, or self-hosted gateways.

It would be great to have first-class support for OpenAI-compatible providers, for example:

openai({
  apiKey,
  baseURL: 'https://api.openrouter.ai/v1',
})

or a generic openaiCompatible() adapter.

Why this matters

• Easier provider switching
• Lower cost / fallback models
• Wider ecosystem support
• No breaking changes

Thanks for considering this
