GPT 6.1 Sol
A large language model in OpenAI's GPT series, designated version 6.1 with the codename suffix "Sol". It represents an incremental update within the GPT model line. Detailed technical specifications and capability profiles have not been fully disclosed publicly.

Timeline (last 90 days)
In the "Tower of Babel" 3D generation test, Gemini 4 showed floating figures, characters stuck motionless, rigid arrangement and problems with water handling, while the figures in GPT 6.1 Sol had clearer design intent and behavioral intent, with overall completion a level higher.
In the game generation test, the mini-game control system generated by Gemini 4 was "pretty bad", making the gameplay hard to understand, and characters got stuck; by contrast, the game generated by GPT 6.1 Sol was at least playable and characters did not run around everywhere.
In the 3D generation test with the "Golden Gate Bridge" prompt, Gemini 4's coherence and 3D texture were good, the water texture was impressive, and the UI was thoughtfully designed; the author considers it on par with or even slightly better than Sonnet 5.5, but GPT 6.1 Sol is superior.
Convovo's research posed forced choices on nearly 500 electoral matchups to Grok 4.7 and GPT 6.1 Sol via API, with Grok choosing Republicans in 92% of responses and GPT choosing Democrats in 97%.
The 54-second rope animation produced by GPT 6.1 Sol at medium reasoning effort clearly shows the rope passing over and under, whereas neither version of Kimi K3.1's animation makes the rope's occlusion and interleaving relationships recognizable.
Tech blogger Matthew Berman, after hands-on testing, commented that Kimi K3.1 is a great model but still has a distance to go before Opus 5.5 and GPT 6.1 Sol.
The finished film delivered by GPT 6.1 Sol is 54 seconds long, with clear story causality and complete music, subtitles, web page and MP4, but the stage is simple, the cat's physical performance is sparse, and the shot layering is limited.
GPT 6.1 Sol completed the short film project in Codex using high reasoning effort, taking about 12 minutes 27 seconds from request to delivery, with a cumulative 2.755 million tokens, of which 29,884 were output and about 2.634 million were cache reads.
Opus 5.5 scores 66.4% on TerminalBench, about 24 points higher than DeepSeek 1017; GPT 6.1 Sol leads 1017 slightly on DeepSWE at 75.2%.
On the Artificial Analysis index, Claude Opus 5.5 scores 58, while Gemini 4 Argon and GPT-6 Astra both score 53.
