OpenAI introduced GPT-6.1-Sol at its DevDay 2026 keynote on September 29, billing it as “near-Astra intelligence” for one-fifth of the price. Simon Willison covered the keynote live and published a pelican graphic for the model. He found the result not notably different from pelicans in the wider GPT-6 family.
Willison said he was late posting the graphic because he was live-blogging the event. His links placed the GPT-6.1-Sol image beside an earlier collection of GPT-6 family pelicans. That context supports his conclusion that the visible change is subtle despite the model’s ambitious value proposition.
The release comes amid intensifying competition among major AI models. On September 22, Willison had written about Claude Opus 5.5, GPT-6 Sol, GPT-6 Luna, and “a new price war.” Seven days later, GPT-6.1-Sol added another GPT-6-named option to that market.
If the one-fifth price claim is accurate, GPT-6.1-Sol could make advanced performance more accessible to developers. However, the source gives no API rates, pricing baseline, benchmark table, or explanation of what “near-Astra” means. It therefore signals a potentially important offer but does not provide enough evidence to verify the commercial or technical claim.
Willison’s reaction is notably restrained: he neither declared a breakthrough nor dismissed the release. By linking the new pelican chart with existing GPT-6 graphics, he gave readers a direct visual comparison. His brief assessment suggests that GPT-6.1-Sol’s strongest immediate story may be cost rather than a visibly different result.
Further reporting will be needed on pricing, availability, and real-world performance. Direct comparisons with GPT-6 Sol, GPT-6 Luna, and Claude Opus 5.5 would show whether the claimed savings change the competitive field. For now, the September 29 announcement stands as a notable price proposition, while its near-Astra capabilities remain insufficiently documented in the available material.
