OpenAI’s aggressive iteration on the GPT-6 family drives current trader sentiment for the next Sol-tier model at 6.2 or higher. The company released flagship GPT-6 Astra on September 3, followed by GPT-6 Sol and Luna variants on September 22 with 50% lower API pricing than GPT-5.6 equivalents, then GPT-6.1 Sol at DevDay on September 29. These updates emphasize improved alignment, computer-use benchmarks, coding performance, and efficiency for the large language model line. While Anthropic’s Claude Opus 5.5 and Google’s Gemini releases compete on capability, OpenAI’s control of the GPT naming and Sol positioning for cost-effective frontier performance reinforces expectations of continued in-house releases. Key near-term catalysts include any additional post-DevDay variants or safety-gated expansions.
