OpenAI launches GPT-6 Sol and Luna with 50% price cut, expands model family
On September 22, OpenAI announced two new GPT-6 models, Sol and Luna, expanding its GPT-6 family less than three weeks after the flagship Astra launch. The models are priced 50% lower than GPT-5.6 promotional rates, attributed to improved caching and inference efficiency. Sol and Luna inherit Astra's technical advances but are optimized for speed and cost, targeting high-frequency coding, agent workflows, and enterprise automation. They are available immediately to Plus, Pro, Business, Enterprise, and Edu users via ChatGPT Work and Codex, as well as API; free and Go users can access Luna on desktop. The release signals a strategic shift from competing solely on capability to scaling cost-effective AI deployment, as rival Anthropic also launched a cheaper Claude Opus 5.5 model on the same day.

Read sourceOpenAI's GPT-6 Sol and Luna halve costs versus GPT-5.6, with mixed benchmark results
OpenAI has launched GPT-6 Sol and Luna, two new AI models that halve pricing compared to GPT-5.6 Sol and Luna. GPT-6 Sol drops from $4/$20 to $2/$10 per million input/output tokens, and Luna from $0.20/$1.20 to $0.10/$0.50, with the same cache discounts. The Artificial Analysis Intelligence Index shows GPT-6 Sol costs $1.06 per task (50% less than GPT-5.6 Sol) and Luna $0.07 per task (60% less). In the Coding Agent Index, Sol improves 2 points to 57, while Luna regresses 2 points to 41. Both models show significant hallucination reduction: Sol's rate drops from 92% to 60% and Luna's from 93% to 77%, though Sol achieves this by declining to answer more often. Performance is mixed across other evaluations: both improve in AutomationBench-AA and Terminal-Bench 4.0, but regress in GDPval-AA v2.1 (Sol drops ~100 Elo points, Luna ~75) and Luna drops ~45 Elo points in AA-Briefcase v1.1. The analysis attributes regressions to reduced presentation quality and omitted rubric elements.
