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

A nostalgic thread recounts highlight moments from various model releases, including the belief that GPT Astra 6 would go unbeaten for at least two months.

A repost says Astra produced what may be the most detailed and accurate AI-generated 3D scene, with over 400 details.

Someone had GPT-6 models act as agents and fight each other in DOOM across 120 matches, with Astra standing out.

TokenGremlin lays out OpenAI's plans: GPT-6.1 Astra, said to be stronger than Opus 5.5; Aeon, aimed at Grok Bot; and a new $500–$1,000 tier, while worrying that frontier intelligence will serve only 1% of people.

A leak says OpenAI may add a ProMax tier above Pro priced at $500–$1,000, with an internal model reportedly stronger than Astra even at its lowest reasoning level.

The author had GPT-6 Astra write Three.js code to build a conceptual X-16 engine with four cylinder banks, a single crankshaft and exposed mechanics, and released the code as open source.

The author says that with Opus 5.5 and GPT-6 Astra, their test harness now writes evals, simulates calls, grades results, opens PRs and reviews them, with humans still handling merge and deploy.

In a video clip, OpenAI CEO Sam Altman says he has a few hundred agents running with GPT-6 Astra every night.

A joking comparison asks why anyone would use Opus 5.5 at medium effort when GPT-6 Astra at ultra effort costs 10x more, runs 10x slower and is half as intelligent.

The author gave Opus 5.5 and Astra 6 the same prompt to improve a watch face they had made, and says Opus has about 10x the taste, with comparison images attached.

Vercel AI Gateway data from the past two months shows OpenAI's spend share rising from 10% to 24%, driven mainly by Astra and 5.6 Sol.

A developer used Astra to generate a Three.js scene that animates each antenna's elevation and azimuth from real-time Nexus data and reproduces the Sun and Moon positions, as a tool for debugging the array.
