Summary
OpenAI released GPT-6 Sol and GPT-6 Luna on Tuesday, cutting their API prices in half versus GPT-5.6's promotional rates. The release happened minutes after Anthropic launched Claude Opus 5.5. OpenAI says its internal coding-deception rate fell to 1.3% for Sol and 2.8% for Luna, both far below GPT-5.6 Sol's 10.4%. Sol and Luna sit below GPT-6 Astra, the model OpenAI called "the most intelligent and aligned model in the world" when it launched on September 3.
