Head-to-head
Ox Alpha vs GPT-5.6 Sol
GPT-5.6 Sol leads on agentic coding and ecosystem maturity; Ox Alpha more than doubles the context and is free.
OpenAI
GPT-5.6 Sol is the all-rounder to beat — the strongest agentic-coding scores and the most mature tooling around it. Ox Alpha trades blows on general intelligence, more than doubles the usable context window, and costs nothing in preview. For raw exploration and long-context work the value is lopsided; for shipping production agents, the tooling still favors OpenAI.
