GPT-6.1 Sol is here. Upgraded with stronger agentic coding... and computer use, near-Astra performance, and cached input at a 95% discount to standard input pricing. GPT-6.1 Sol is built for complex refactors, deep codebase investigations, and long-running agents across apps.show more

OPENAI 🔥: GPT-6.1 Sol Ultrafast is rolling out on... ChatGPT Work, Codex, and the API. > GPT-6.1 Sol in Ultrafast mode is $12 per million input tokens and $60 per million output tokens. > Ultrafast mode delivers 8x faster speeds than Sol Standard. Ultrafast testing time 👀show more

GPT Astra vs. GPT-6.1 Sol and every previous Sol... generation on the Mario test. Same prompt, same test. Astra still wins, finishing in just 15m 37s for $2.96. GPT-6.1 Sol took 34m 38s, more than twice as long, but cost just $0.64 and delivered the best result of any Sol model. Astra is still ahead, but 6.1 Sol is getting surprisingly close for a fraction of the price.show more

Ultrafast is rolling out today for GPT-6.1 Sol in... the API, Codex, and ChatGPT Work. Near-Astra intelligence at up to 8x faster speeds than Sol Standard, so you can build as fast as the ideas come.show more

OpenAI DevDay is now finished. Here's what matters for... creators: → dots: always-on agents powered by GPT-6 Astra → GPT-6.1 Sol, the most cost-efficient model → Up to 4K apps, including Magnific → UltraFast: responses at 300 tokens per second OpenAI x Magnific now availableshow more

What did OpenAI just feed GPT SOL 6.1?? asked... it to build a 3D axe from scratch using Blender MCP - 7 minutes total - 1% of weekly quota since when is GPT SOL 6.1 this good at 3D?show more

6.1 Sol!! Astra but cheaper and faster. Post training... is solved.show more

🚨 codex users!! We have a good and a... bad news!! I used GPT-6.1 Sol at MAX and I got: - 2% weekly usage - 2.8 Million tokens - 52 mins of work The usage is GOOD!! You can use it for a LOT of work for only $20 Now the "BAD" news It is EXTREMELY SLOW!! And quality isn't great... (Check video) The city is smaller than what GPT-6 Astra built!! AND the car animations are lagging... I'd suggest using it as "implementor" and Astra as "orchestrator". NOTE: I used MAX because THAT is only on par with GPT-6 Astra.show more

Did OpenAI quietly route GPT SOL 6.1 to another... model?? compared Astra vs SOL side by side on a 3D model from scratch using Blender MCP: - Astra: drained 13% quota, 26 minutes - SOL 6.1: only 4% quota, 49 minutes so what's the point of using Astra anymore?show more

I don't even know why I tried GPT 6.1... Terra in Blender - left output: 23 minutes and 1% - right output: 6 minutes and 0% one is Sol 6.1 Extra High, the other is Terra 6.1 Extra High the choice is obvious = I'd never trade quality for speedshow more

Design team COOKED w/ the GPT 6.1 Sol banner again!!

GPT-6.1 Terra vs GPT-6.1 Sol vs Kimi K3.1 Pro... Max vs Muse Spark 1.3 GPT-6.1 Terra just dropped, so I threw it straight at the Eiffel Tower benchmark 🗼🇫🇷 Same prompt for all four. • GPT-6.1 Terra: $0.44, 5m 33s • GPT-6.1 Sol: $1.10, 22m 28s • Kimi K3.1 Pro Max: $3.12, 40m 30s • Muse Spark 1.3: Free, 17m 01s Honestly, Terra blew me away. 🤯 The whole of Paris in under 6 minutes, for 44 cents. That's 4x faster than Sol and 7x faster than Kimi. ☁️ Sol's blue sky and that shot under the tower are beautiful. 🏛️ Kimi has the finest lattice and those Paris rooftops. 🆓 And Muse Spark did it for free! What do you guys think? Which Paris wins for you? 👀show more

Fusion is the most efficient frontier harness for GPT... 6 Astra and Claude Fable 5.1. You can also configure everything about it: • Base model: Fable, Astra, Sol, or Opus • Sidekick model: SWE (Free), Luna, Sol, GLM (Free) • Speed: Normal or Fast ⚡ • Reasoning level It retains Claude Fable 5.1 and GPT-6 Astra performance while reducing costs and is the first time a multi-model coding agent has been included on the Artificial Analysis Coding Agent Index! Importantly: it's also fun to use :)show more
