OpenAI is dropping GPT-5.6 Sol API and credit pricing by over 20% for the next three months. The cut is live on the API and rolling out to eligible ChatGPT Work and Codex credits. Pro, Plus, and Business subscription usage is unchanged. For high-volume coding agents, this is a direct unit-cost reduction on the flagship coding model.
Key Takeaways
- ✓Codex and Work credit users get a cheaper Sol for a quarter—useful for longer agent sessions.
- ✓Subscription-plan usage is unchanged; the cut hits API and credit billing paths.
- ✓The window is three months, so production routing to Sol should be evaluated against that horizon.
