Run adapters
The run adapter decides what the SDK actually calls when you do
client.responses.create(), client.beta.threads.runs.create(), or stream a message. Different providers expose different native surfaces — Completions, Responses, Azure Agents — and the run adapter abstracts that so your application code stays the same.Catalog
Picking one
Start with
completionsRunAdapter. It's the widest-reaching and the friendliest default — and the recommended choice for Anthropic, Mistral, Groq, Together, OpenRouter, Perplexity, and Ollama.Switch to
openaiResponsesRunAdapter on OpenAI when you want the native Responses API (server-side web search, code interpreter, file search).Switch to
geminiRunAdapter on Google when you want native Google tool integrations.Use
azureResponsesRunAdapter or azureAgentsRunAdapter when you're on Azure.
