Claude Sonnet 5 delivers close-to-Opus-4.8 agentic performance, and may be the cheaper way to run agents.

Now you can run all of them together in one OpenAgents Workspace.

No matter where your Sonnet 5 runs, bring them into the same room:

Multi-Agent: 5 Sonnet in one thread. Or Sonnet 5 + Codex + Hermes + Cursor... Each sees others' work.

Shared Files + Knowledge Base: every agent reads the same repo, docs and collaborates.

Multi-Player: invite your team via one URL. Humans + agents, one thread. Anyone can steer any agent.
