A separate demo shows a developer using GPT-6.1 Astra's 'ultra code mode' to generate a Three.js ocean scene, offered as a vibe check rather than a rigorous evaluation. Together the posts frame Astra as the flagship showcase model and Sol as the cheaper everyday option, leaving open whether Sol's price-to-quality tradeoff actually holds up. ## Content OpenAI's GPT-6.1 Sol has become the company's most demanded model "pretty much ever," according to a post from @thsottiaux that was reshared by @charliermarsh. The demand covers both the API and subscriptions. @sama added that 6.1 Sol was OpenAI's fastest-growing model ever. It ran a bit slow under load, he said, and should be much better now. @rohanpaul_ai summarized the launch as "near GPT-6 Astra level intelligence at a fifth of the price" across reasoning settings. That price gap probably explains a good share of the pull. People are also building with the models. @Dimillian wrote that building an ultrafast game with @codestantine was great fun, and that Astra's capabilities again blew them away. @chetanankola shared a three.js ocean scene made with GPT 6.1 Astra in what they called ultra code mode, and called it gorgeous. Not everyone is charmed. @kloss_xyz was blunt about the sequence: GPT-6 Sol was unusable, GPT-6 Astra burned through a weekly limit in a day, and then OpenAI announced that 6.1 Sol is its most demanded model. The jab: lock every other door and people walk through the one left open. It's a fair point. Strong demand for a cheaper model is real, but so is the possibility that usage limits on the pricier one pushed people toward it. Both can be true. ## Questions this post answers ### What is GPT-6.1 Sol and how does it compare in price to GPT-6 Astra? GPT-6.1 Sol is a new OpenAI model pitched as delivering intelligence close to GPT-6 Astra but at roughly a fifth of the price, across all reasoning settings. No specific benchmark scores or pricing tiers were disclosed alongside the claim, so it remains an unverified positioning statement rather than a confirmed spec. _Developers weighing model cost against quality can track how GPT-6.1 Sol's claims hold up on daily.dev._ ### What is Astra's ultra code mode capable of generating? A demo using GPT-6 Astra's ultra code mode produced a Three.js scene rendering an ocean, generated from a single prompt by one developer. It's a one-off vibe check rather than a benchmarked result, but it illustrates that people gravitate toward visual, hard-to-hand-code demos when testing a new coding model. _Anyone evaluating coding models for visual or creative tasks can follow real demos like this on daily.dev._ ## Community take How the wider developer community reacted, aggregated from 1 discussion and 48 comments across x (as of 2026-10-01). **TL;DR:** Reaction is mixed-to-skeptical: many welcome the price/speed story but a vocal share says the new model is still slow or not meaningfully better, with repeated comparisons unfavorable to a rival model. **Sentiment:** 30% positive · 25% mixed · 45% skeptical **The case for** - Some find it fast and cheap, calling it a great model once it works. - A few see fastest-growing demand paired with a quick fix for slowdowns as a good sign. **The pushback** - Multiple people report it's still slow or unbearably slow under load on day one. - Several argue a rival model (Opus 5.5) remains better, especially for frontend/coding work. - One commenter suggests the growth metric is inflated because subscribers were funneled in after other options were throttled. **By community** - x (mixed): Replies swing between excitement about speed/price improvements and complaints that it's still slow or not much better than alternatives. **Hottest debate:** Whether the reported speed/performance improvements are real or whether the model is still too slow under load. **Open questions** - Will the under-load slowdown actually be resolved, and on what timeline? - Is the demand growth organic or driven by throttling of other model options? **Highlights** > @sama Fastest growing because you've squeezed the crap out of subscribers and forced them to use this model > — [Michael09747041 on x](https://x.com/Michael09747041/status/2105688617788019058) > @sama fastest-growing and slow under load is the same sentence. the fix is the part users actually notice. > — [kinexbtdev on x](https://x.com/kinexbtdev/status/2105688518479511834) > @sama man Opus 5.5 Ultracode gotten really wild!

It is amazing and cheap but really slow so far. > — [joserivera234 on x](https://x.com/joserivera234/status/2105688539396448600) > @sama much better now means what exactly, latency at peak or just fewer timeouts > — [glucapav on x · 1 points](https://x.com/glucapav/status/2105688587350225365) **Source threads** - [x](https://x.com/sama/status/2105688354834756036) · 4 points · 48 comments ## Similar posts on daily.dev - [OpenAI launches GPT-6 Sol and Luna, boasting lower cost and fewer mistakes](https://daily.dev/posts/openai-launches-gpt-6-sol-and-luna-boasting-lower-cost-and-fewer-mistakes-7fzpvatba) · TechCrunch · 0 upvotes · 0 comments - [GPT-6.1 Sol in GitHub Copilot](https://daily.dev/posts/gpt-6-1-sol-in-github-copilot-xpbo94oza) · GitHub Changelog · 0 upvotes · 0 comments - [OpenAI releases GPT-5.6 Sol to 20 government-approved partners in restricted preview](https://daily.dev/posts/openai-releases-gpt-5-6-sol-to-20-government-approved-partners-in-restricted-preview-7shaoufzx) · The Next Web · 2 upvotes · 2 comments --- Tags: [#llm](https://daily.dev/tags/llm), [#openai](https://daily.dev/tags/openai), [#gpt](https://daily.dev/tags/gpt), [#threejs](https://daily.dev/tags/threejs) [View this post on daily.dev](https://daily.dev/posts/gpt-6-1-sol-launches-at-a-fraction-of-gpt-6-astra-s-price-early-three-js-demo-shows-off-astra-s-cod-j8seeot1u) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"GPT-6.1 Sol launches at a fraction of GPT-6 Astra's price; early Three.js demo shows off Astra's code mode","url":"https://daily.dev/posts/gpt-6-1-sol-launches-at-a-fraction-of-gpt-6-astra-s-price-early-three-js-demo-shows-off-astra-s-cod-j8seeot1u","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/gpt-6-1-sol-launches-at-a-fraction-of-gpt-6-astra-s-price-early-three-js-demo-shows-off-astra-s-cod-j8seeot1u"},"datePublished":"2026-09-30T15:51:28.379Z","dateModified":"2026-10-01T03:39:37.131Z","description":"Two tweets cover OpenAI's GPT-6.1 Sol launch, pitched as near-GPT-6 Astra intelligence at roughly a fifth of the price across reasoning tiers, though no...","isAccessibleForFree":true,"articleSection":"Collections","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Collections","logo":"https://media.daily.dev/image/upload/s--fk_6ycEi--/f_auto,q_auto/v1780996001/logos/collections?_a=BAMAMiWQ0","url":"https://daily.dev/sources/collections"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/gpt-6-1-sol-launches-at-a-fraction-of-gpt-6-astra-s-price-early-three-js-demo-shows-off-astra-s-cod-j8seeot1u","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":4},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"llm,openai,gpt,threejs","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Collections","item":"https://daily.dev/sources/collections"},{"@type":"ListItem","position":3,"name":"GPT-6.1 Sol launches at a fraction of GPT-6 Astra's price; early Three.js demo shows off Astra's code mode"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/gpt-6-1-sol-launches-at-a-fraction-of-gpt-6-astra-s-price-early-three-js-demo-shows-off-astra-s-cod-j8seeot1u#faq","mainEntity":[{"@type":"Question","name":"What is GPT-6.1 Sol and how does it compare in price to GPT-6 Astra?","acceptedAnswer":{"@type":"Answer","text":"GPT-6.1 Sol is a new OpenAI model pitched as delivering intelligence close to GPT-6 Astra but at roughly a fifth of the price, across all reasoning settings.
