The OpenAI Agents SDK is a lightweight Python framework for building multi-agent workflows. It supports 100+ LLMs, provides built-in guardrails, handoffs between agents, MCP tool integration, tracing, sessions, and real-time voice capabilities.

Batch-generate images through the OpenAI Images API with a prompt sampler and gallery output.

Use the upstream install or setup path that matches your environment: - npm install openai - npx jsr add @openai/openai

API-based speech-to-text transcription through OpenAI. No local model downloads, no GPU, no Python ML stack — just an API key and a shell script.

Local speech-to-text transcription without relying on an API.

OpenAPI Generator turns OpenAPI specs into client SDKs, server stubs, docs, and config. It is a practical fit when you need repeatable API scaffolding from a contract-first workflow.
