@gemstack/ai-sdk

AI engine: providers, agents, tools, streaming, middleware, structured output, conversation memory, evals, MCP, computer-use, and testing fakes.

The first GemStack package. Spun out of Rudder's @rudderjs/ai (carried forward from the 1.17.x line, renamed and re-versioned under the GemStack umbrella). The Rudder package now ships as a thin deprecated re-export of this one.

Status

@gemstack/ai-sdk starts at 0.1.0. The code is mature, but the version line is intentionally reset: the public surface is being decoupled from Rudder (the @rudderjs/core / @rudderjs/orm coupling and the ORM-backed subpaths are moving behind a neutral, optional adapter seam) so the package stands alone in any Node app. Expect the API to firm up toward 1.0.0 as that decoupling lands.
