OpenAI's rapid GPT-6 family rollout drives trader sentiment on the next Sol (6.2+) release, with GPT-6.1 Sol shipping September 29 at DevDay after GPT-6 Astra (early September) and GPT-6 Sol/Luna (September 22). These models emphasize agentic coding, computer use, and professional workflows at lower token costs than prior GPT-5.6 variants, with Sol positioned as the balanced high-performance tier between flagship Astra and cheaper Luna. The pace reflects OpenAI's push to expand the GPT-6 lineup for different scales while maintaining safety alignments post earlier incidents. No confirmed timeline exists for 6.2+, though ongoing API updates, Intelligent UI expansions to ChatGPT, and competitive pressure from rivals suggest traders watch for the next major Sol iteration or full generation bump before year-end.
