GPT-6 Astra in Practice: Tests, Use Cases, and Feedback

A Spanish-language user lists all DevDay releases: GPT-6.1 Sol pitched as 'almost Astra at one-fifth the price', plus Agents API, Codex in Cloud, a $500 plan and more.

The OpenAI-model portion of Devin sessions is paid for by the ChatGPT plan, and pairing Astra with SWE-2 lets the quota stretch further.

A rundown of OpenAI Dev Day complaints: the Dottie demo went poorly, GPT-6.1 Sol beats Astra only on medium/high tiers, the 20x Pro plan now costs $500, and Ultrafast is realistically about 5x faster.

OpenAI says Ultrafast in Codex runs up to 8x faster than Astra Standard and 4x faster than Astra Fast, aimed at coding at the speed you type.

A Turkish account rounds up all DevDay 2026 releases: GPT-6 Astra-powered Dots agents, GPT-6.1 Sol, the $500 Pro plan and the Ultrafast inference layer.

A brief Dev Day list covering the Dots personal assistant, a $500/month plan with Ultrafast, GPT-6.1 Sol, the Decisions API, and signing in to third-party apps with ChatGPT.

The author says GPT-6.1 Sol performs near Astra level at Sol pricing, and criticizes the new $500 tier, quota cuts to older plans, and the positioning of the Decisions API.

Given the same physics simulation task, Claude Opus 5.5 and GPT-6 Astra perform about equally, but Astra's estimated API cost is roughly 40% higher ($12.95 vs $7.70).

Sam Altman says 6.1 Sol costs one-fifth of Astra's price and offers a 95% cache read discount, calling it an extremely capable model.
