- OpenAI presents Sol and Luna as lower-cost members of the GPT-6 family, extending model choice for businesses running repeated professional and coding tasks.
- The company describes improvements in instruction following, factuality, and computer use, but its published evaluations do not establish performance on a particular business workflow.
- Standard API rates are $2 input and $10 output per million tokens for Sol, compared with $0.10 input and $0.50 output for Luna.
- The Register places the release alongside Anthropic’s Opus 5.5 launch, showing competitors introducing new models while businesses are still deciding how to deploy them.
