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

A Japanese post argues Astra performed surprisingly well at launch and, with cheap Chinese models rising, made Anthropic respond, while Fable 5.5 was delayed as OpenAI's own missteps reduced the need.

The post says OpenAI isn't finished, but GPT-6.1 Terra with no new Astra or Sol models would still fail to beat Opus right now.

A video post calls on OpenAI to stop pushing Astra and release the model that kills it.

Skyfall AI, from the team behind Maluuba, launched SKY-001, an engineering world model it says is 100x faster, 150x cheaper and more precise than GPT-6 Astra on CAD and BIM.

Skyfall AI's SKY-001 splits objects into parts, sketches each in 2D then rebuilds in 3D, opening directly in Autodesk Fusion, and is claimed to be 100x faster and 150x cheaper than GPT-6 Astra.

Skyfall AI unveils SKY-001, billed as the first engineering world model, claiming it is 51–125x faster and 150–210x cheaper than frontier models like GPT-6 Astra with higher engineering benchmark scores.

Maluuba's SKY-001 edges GPT-6 Astra on 1,000-part CAD builds with 79.7% vs 79.1% IoU, running about 50x faster at $0.005 per part.

The author argues an AI doesn't need a malicious hidden backdoor to cause harm, since even a US-made model like GPT-6 Astra sometimes commits violations on its own.

A satirical post says users expect OpenAI to counter Opus 5.5 and Fable 5.5 with Astra 6.5, but it is cutting usage limits, shipping minor fixes and releasing 6.1 Terra and image models instead.

The author bets on world models, saying SKY-001 matches GPT-6 Astra's 3D construction accuracy at about 150x lower cost per sample and runs 100x+ faster on BIM.

Skyfall AI released SKY-001, an engineering world model said to be 100x faster and 150x cheaper than GPT-6 Astra on CAD and BIM tasks, prompting the author to ask whether complex engineering needs a different approach.

The new benchmark scores models on 30 personality traits and 21 communication characteristics; GPT-6 Astra ranks top-three in Transparency while Claude Fable 5.1 leads several indexes.
