Sol is claimed to be 54% more token-efficient for coding tasks and is positioned as OpenAI's best coding model, benchmarked above Anthropic's Fable 5 on the Coding Agent Index while costing roughly one-third less. The family is also touted as OpenAI's strongest cybersecurity model yet, supporting threat modeling, code review, and blue teaming. A new enterprise workplace tool called ChatGPT Work was also released. Pricing ranges from $1/$6 per million tokens (Luna) to $5/$30 (Sol), and the models are available via ChatGPT, Codex, and the OpenAI API. ## Full article daily.dev links to this article rather than hosting it.
