Merged summary
TL;DR - OpenAI cut GPT-5.6 Luna API prices by 80% and Terra prices by 20%, while adding a faster Sol mode. The changes lower the cost of deploying high-frequency agent workflows such as code review, monitoring, and validation.
- Luna now costs $0.20 per million input tokens and $1.20 per million output tokens; Terra costs $2 and $12, respectively.
- Sol remains $5/$30 per million tokens; its Fast mode delivers up to 2.5× the speed for 2× the standard price.
- OpenAI attributes savings partly to Sol-assisted GPU kernel optimization and speculative decoding, reportedly reducing serving costs by 20% and improving token-generation efficiency by over 15%.
- ChatGPT and Codex CLI auto-review will move from GPT-5.4 to Luna, with OpenAI estimating roughly a 90% cost reduction for that workload.
