Methods
Get the credentials for the underlying AI provider.
Get the provider connection configuration other than the driver, key, and name.
Get a provider instance that sends the given HTTP headers with each request.
Run the given gateway call, dispatching the event built from its exception before rethrowing.
Format the given provider / model list.
Get provider and model pairs without discarding on-demand instances.
Restore the provider from its serialized representation.
Get embedding vectors representing the given inputs.
Determine if the provider may omit dimensions and use a model's native embedding dimensions.
Validate embeddings inputs against the provider's supported media types.
Generate an image.
Get the tool approval to resume with, unless a faked agent has no paused approval to resume.
Replace another provider's raw paused-turn replay state with its generic mapping, since raw blocks are only valid verbatim on the provider that produced them.
Determine whether the prompt is a resume that runs the approved tools.
Get a callback that captures a resume's resolved approval results for its completion event.
Resolve the tools for the given prompt, wrapping any agent instances as tools.
Get the tools the agent declares, including the tool that loads its skills.
Resolve a tool returned by the agent into a native tool instance when needed.
Build the run's context, letting a remembered conversation claim and record the approval decisions the run resumes.
Build the context that identifies this run and reports its step and tool events.
Dispatch the terminal failure event for a run, unless the caller may still retry it against another provider.
Throw when a pause has surfaced on a prompt that cannot be resumed from persisted or replayed history.
Get the provider's embedding gateway.
Get the provider's image gateway.
Get the provider's reranking gateway.
Get the provider's text gateway.
Get the multi-step text generation loop wrapping the provider's text gateway.
Rerank the given documents based on their relevance to the query.
Get the credential holder shared by this provider's gateways.
Get the name of the default text model.
Get the name of the cheapest text model.
Get the name of the smartest text model.
Get the name of the default embeddings model.
Get the default dimensions of the default embeddings model.
Get the name of the default image model.
