What happened
OpenAI announced GPT-6 Sol and GPT-6 Luna on 22 September 2026. This is one release with two jobs, not two separate products to cover twice.
OpenAI positions Sol for complex coding and agentic workflows. It positions Luna as the efficient model for focused, high-volume work.
The announcement says both models roll out in ChatGPT Work and Codex for Plus, Pro, Business, Enterprise, and Edu. Both are in the API. The same post says Free and Go users can try GPT-6 Luna in the desktop app.
The prices on the model pages
The GPT-6 Sol page lists $2.00 input, $0.20 cached input, and $10.00 output per million tokens. The page says to call gpt-6-sol.
The GPT-6 Luna page lists $0.10 input, $0.01 cached input, and $0.50 output per million tokens. The page says to call gpt-6-luna.
OpenAI’s announcement says these API prices are 50% lower than GPT-5.6 promotional pricing. Keep that comparison attached to OpenAI and to the promotional rates it named. It is not a Pinoy AI Works price study.
The announcement also says a banked rate-limit reset was loaded for Plus, Pro, and Business accounts. Users apply it when they need it.
Why it matters in the Philippines
Many Filipino freelancers, agencies, startups, and operations teams live on mid-tier chat and API models, not the most expensive frontier model.
Sol is the one to test when the job is harder code or a multi-step agent. Luna is the one to test when the job is repeated drafting, sorting, or classification.
A Free or Go trial of Luna is useful only where OpenAI said it is available: the desktop app. Do not tell a reader it is free on every phone or browser.
What to do next
- Test Sol on a hard coding task and Luna on a repetitive task.
- Measure the full workflow cost before you replace a production model.
- Use gpt-6-sol and gpt-6-luna in API calls if you are leaving older aliases.
- Keep the 50% line attributed to OpenAI’s comparison with GPT-5.6 promotional pricing.
How this was checked
Availability, the desktop limit for Free and Go, and the 50% comparison were read in OpenAI’s 22 September 2026 community announcement on 25 September 2026. The dollar rates were read the same day on the GPT-6 Sol and GPT-6 Luna API pages. No separate openai.com/index blog post was required for those facts.
