@rulvar/bridge-ai-sdk

Bridge adapter that wraps a Vercel AI SDK LanguageModelV4 model as a Rulvar provider adapter, covering the long tail of providers; models on other specification versions are rejected by a runtime check, and the package is, by design, the highest-churn one in the project. Exports bridgeAiSdk.

Part of Rulvar, an embeddable TypeScript engine for durable, budget-bounded multi-agent LLM workflows, where a completed LLM call is never paid for twice. Full documentation: docs.rulvar.com.

Install

pnpm add @rulvar/core @rulvar/bridge-ai-sdk

Add the AI SDK provider package you are bridging alongside it.

Documented as the highest-churn package of the set: it tracks the @ai-sdk/provider major line and its provider-major bumps are the most likely driver of post-1.0 BREAKING majors.
