The reviewer then benchmarks GPT-6.1 Sol against eight custom coding tasks (KingBench 3) run through Codex, covering an elevator simulator, a 3D contact lens case, a folding table, an SVG panda, an archery game, a combinatorics problem, local model fine-tuning, and a 3D wristwatch. The model scores 78/80 (97.5%), beating its predecessor's 82.5% but trailing Opus 5.5's reported 93.75% and GLM 5.3's 91.25%, with notable weaknesses in elevator dispatch logic and folding-table geometry collisions. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What are the API pricing and context window specs for GPT-6.1 Sol? GPT-6.1 Sol's API pricing is $2 per million input tokens and $10 per million output tokens, with cached input at 10 cents per million, for requests up to 272,000 input tokens; longer requests use different rates. The API supports a context window just over 1 million tokens and a maximum output of 128,000 tokens. _Track pricing and context-window changes across model releases like this on daily.dev before budgeting an API integration._ ### How did GPT-6.1 Sol score on the KingBench 3 coding benchmark compared to Opus 5.5 and GLM 5.3? GPT-6.1 Sol scored 78 out of 80 points (97.5%) across eight KingBench 3 coding tasks run through Codex, up from an earlier GPT-6 Sol score of 82.5%. For reference, GLM 5.3 scored 91.25% and Opus 5.5 scored 93.75% in earlier separate reviews, so Sol still trails Opus 5.5 despite the jump. _Compare fresh model benchmark results like these on daily.dev when deciding which coding assistant to adopt._ ### What is OpenAI's Ultrafast tier and how much faster is it for coding tasks? Ultrafast is a premium OpenAI tier claimed to generate tokens up to eight times faster in Codex and up to six times faster via the API. Astra Ultrafast is available immediately, while GPT-6.1 Sol Ultrafast is coming soon; access requires the $500/month Pro-500 plan (25x the Plus usage allowance) or a separate premium API pricing option for eligible enterprise customers. _Weigh speed-tier pricing tradeoffs like this on daily.dev before upgrading your coding-agent workflow._ ## Similar posts on daily.dev -
