OpenAI releases GPT-6 Sol and Luna as two models, fires three employees
OpenAI announced the simultaneous launch of two GPT‑6 variants, Sol and Luna, on 2 October 2026. The company has not yet disclosed benchmark results, pricing, or API details, and the names are only speculated to indicate a heavier, reasoning‑focused model (Sol) and a faster, lightweight version (Luna). The same day, OpenAI reported that three staff members were dismissed for allegedly leaking…
Key points
- OpenAI launched two GPT‑6 variants, Sol and Luna, without releasing benchmarks or pricing
- Three OpenAI employees were fired the same day for alleged confidential‑info leaks
- The article recommends waiting for official data and running A/B tests before switching models
The article advises engineers to wait for public benchmarks and to conduct small‑scale A/B tests before deciding whether to replace existing RAG pipelines or agent implementations. It also highlights the need to review contracts and data‑handling rules, especially for early‑access participants, as the risk of inadvertent data exposure may rise with broader model access. Competitors such as Anthropic, Google, and xAI are updating their own models, but no immediate counter‑moves have been observed.
Overall, the piece suggests building a system that can benchmark multiple models in parallel and periodically reassess cost‑performance trade‑offs rather than rushing to adopt GPT‑6 based solely on its name.
