feat: add Requesty as an OpenAI-compatible chat model provider

[Thibaultjaigu]

Adds Requesty as an OpenAI-compatible chat model provider, mirroring the existing OpenRouter provider.

Requesty (requesty.ai) is an OpenAI-compatible LLM gateway — one API across many models, using the same provider/model naming as OpenRouter (base https://router.requesty.ai/v1, REQUESTY_API_KEY). Since there's no Requesty-specific AI SDK package, it routes through @ai-sdk/openai-compatible (already a dependency).

Changes

• packages/web/src/features/chat/llm.server.ts — case 'requesty' building the model via createOpenAICompatible (default base https://router.requesty.ai/v1, overridable via config.baseUrl; key from config.token ?? env.REQUESTY_API_KEY; headers mirroring openrouter).
• packages/schemas/src/v3/languageModel.schema.ts — RequestyLanguageModel zod definition mirroring OpenRouterLanguageModel; regenerated languageModel.json + types via yarn generate (the diff is purely the Requesty addition).
• packages/shared/src/env.server.ts — REQUESTY_API_KEY optional env.
• packages/web/src/features/chat/types.ts — provider type.
• packages/web/src/features/chat/components/chatBox/modelProviderLogo.tsx — case 'requesty' (falls back to default; no asset fabricated).
• packages/setupWizard/src/models.ts — wizard entry.
• docs/docs/configuration/language-model-providers.mdx + generated schema snippets — Requesty section in the existing per-provider docs table.

Testing

• tsc --noEmit on @sourcebot/schemas → 0 errors; the edited web files (llm.server, types) → no new errors (remaining errors are pre-existing @/public/*.svg/*.png module-decl + a test-prop issue, present for all providers).
• yarn generate reproduces the committed schema json (zod source and generated json are consistent).
• Verified live: POST https://router.requesty.ai/v1/chat/completions with model: openai/gpt-4o-mini → HTTP 200 with a real completion.

I work at Requesty. This mirrors the existing OpenRouter provider as closely as possible. Happy to adjust or close it if it's not a fit.

Summary by CodeRabbit

• New Features

  • Added support for the Requesty language model provider across setup, chat, and schema validation.
  • Requesty can now be selected as a provider and configured with a model name, API key, optional base URL, headers, and temperature.
  • Added UI support for displaying a Requesty provider icon.

• Documentation

  • Updated configuration docs with Requesty setup details and an example configuration.

Walkthrough

Adds the Requesty OpenAI-compatible LLM gateway as a new language model provider. Changes span the RequestyLanguageModel TypeScript interface and JSON schemas, server-side model factory (llm.server.ts), REQUESTY_API_KEY env var registration, setup wizard provider list, a UI logo fallback, and documentation.

Changes

Requesty provider integration

Layer / File(s)	Summary
RequestyLanguageModel type contracts and schemas packages/schemas/src/v3/languageModel.type.ts, packages/schemas/src/v3/index.type.ts, packages/schemas/src/v3/languageModel.schema.ts, packages/schemas/src/v3/index.schema.ts, schemas/v3/languageModel.json	Defines the RequestyLanguageModel TypeScript interface with provider: "requesty", required model, optional token/baseUrl/temperature/headers, and adds it to the LanguageModel union. Extends JSON schema definitions and oneOf variant lists in all schema files.
Server-side runtime implementation packages/shared/src/env.server.ts, packages/web/src/features/chat/types.ts, packages/web/src/features/chat/llm.server.ts	Registers REQUESTY_API_KEY as an optional env var, adds "requesty" to languageModelProviders, and implements a case 'requesty' in getAISDKLanguageModelAndOptions using createOpenAICompatible with the Requesty base URL.
Setup wizard and provider logo packages/setupWizard/src/models.ts, packages/web/src/features/chat/components/chatBox/modelProviderLogo.tsx	Maps requesty to REQUESTY_API_KEY in PROVIDER_ENV_KEYS, routes the requesty case through the openrouter config path in collectModelConfig, adds Requesty to the interactive provider choices, and returns a Box icon for requesty in ModelProviderLogo.
Documentation and schema reference docs docs/docs/configuration/language-model-providers.mdx, docs/snippets/schemas/v3/languageModel.schema.mdx, docs/snippets/schemas/v3/index.schema.mdx	Adds a Requesty subsection with a JSON configuration example to the provider docs, and extends the rendered schema reference pages with the RequestyLanguageModel definition and oneOf variant.
