 **Recommended models:**
 
 - **Claude Opus 4.6** — Best overall experience. Sisyphus was built with Claude-optimized prompts.
-- **Claude Sonnet 4.6** — Good balance of capability and cost.
 - **Kimi K2.5** — Great Claude-like alternative. Many users run this combo exclusively.
 - **GLM 5** — Solid option, especially via Z.ai.
 
-Sisyphus still works best on Claude-family models, Kimi, and GLM. GPT-5.4 now has a dedicated prompt path, but older GPT models are still a poor fit and should route to Hephaestus instead.

 - **Multi-model orchestration.** Pure Codex is single-model. OmO routes different tasks to different models automatically. GPT for deep reasoning. Gemini for frontend. GPT-5.4 Mini for speed. The right brain for the right job.
 - **Background agents.** Fire 5+ agents in parallel. Something Codex simply cannot do. While one agent writes code, another researches patterns, another checks documentation. Like a real dev team.

 - **Accumulated wisdom.** Subagents learn from previous results. Conventions discovered in task 1 are passed to task 5. Mistakes made early aren't repeated. The system gets smarter as it works.
