What are OpenAI’s GPT-6 Sol and Luna, and which one should you use?
Quick answer: Sol and Luna bring GPT-6 capability to lower-cost everyday work; Astra is the step-up option for unusually long, autonomous computer tasks.
Sol and Luna bring GPT-6 capability to lower-cost everyday work; Astra is the step-up option for unusually long, autonomous computer tasks.
- Start with Sol or Luna for writing, summaries, routine analysis, coding assistance, and workflows where cost per attempt matters.
- Use a small representative task to compare accuracy, speed, and price before moving a whole workflow.
- Move to Astra when the job needs its roughly 1.05-million-token context, full computer use, and reliable execution across many linked steps.
- For every model, limit permissions, require approval before consequential actions, and verify facts, code, and outputs.
Good to know: The rollout is gradual, so model availability can differ by account, product, and API region. Astra’s “Critical” cybersecurity-capability rating is a reason for stronger controls, not a consumer performance score.
