GPT-5.6 Sol Can Now Be Integrated into Claude Code
dr_cintas · x · 2026-07-13
OpenAI's GPT-5.6 Sol can now run inside Claude Code.
The post outlines two integration methods that take just a few minutes:
- Official Plugin: Installing codex-plugin-cc unlocks commands like /codex:review, /codex:adversarial-review, and /codex:rescue.
- Proxy/Alias Method: Use an environment variable to point CLAUDECODESUBAGENTMODEL to gpt-5.6-sol, letting Claude use it directly as the main or sub-agent model.
The author also notes that Claude Code allows manual configuration of the subagent model and effort level. High-intensity runs like Sol Ultra consume several times more tokens, so matching the model and effort to the task size can save real costs.
