Rayline vs Stele

Rayline builds ARC, the orchestrator model that chooses the model and reasoning effort for every turn, plus Workshop, Arena, and the ARC API.

Shared memory for AI coding agents. Claude Code, Cursor and Codex read what your project already decided, so context survives between tools and sessions.

About Rayline

Rayline builds ARC, the orchestrator model that chooses the model and reasoning effort for every turn, plus Workshop, Arena, and the ARC API. Rayline builds ARC, the first adaptive intelligence model, routing every turn to optimize cost and quality. ARC selects the model and reasoning effort most likely to succeed at every turn, at the lowest total cost. ARC works behind the API you already use, matching every request to the intelligence it needs. Production-ready software from an agent that adapts to the work.

About Stele

Shared memory for AI coding agents. Claude Code, Cursor and Codex read what your project already decided, so context survives between tools and sessions. Only one of these agents knows this was tried last spring and rolled back. KNOW-142 : a captcha on checkout shipped last spring and was reverted after two weeks. The bot traffic is real, though it spikes on release days and is quiet the rest of the time. A gate armed only during a release window would avoid repeating that.
