OpenAI Agents SDK in brief

Lightweight Python framework for multi-agent workflows, with tools, handoffs, sessions and tracing.

openai-agents-python v0.24.0 exposes MCP annotations on converted tools and adds run-wide tool exception formatting, alongside session-write and compaction fixes.

What it does well: MIT license, official OpenAI project; Small surface area; MCP, sessions and tracing support.

Where it falls short: Releases are mostly dependency bumps and fixes; Works best with OpenAI models; We only ran it against a local model through the Chat Completions class, not OpenAI's hosted models.

Latest version we cover: v0.24.0 (Oct 15, 2026). Vendor: OpenAI.
