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

A user says model degradation has persisted from 4o through Astra without any notice, hurting paying users, and argues only a genuine residential IP can mitigate it.

The post says Gemini 3.8 Live scores 82.6% on the speech-to-speech index versus Astra's 81.5%, while hourly input costs $0.84 against $5.83.

A Japanese user uploaded a restaurant floor plan PDF and, with a single instruction, had Astra generate a 3D model of the interior that can be walked through.

Someone connected GPT-6 Astra, GPT-5.6 Sol and Luna to an open-source Bomberman game where each model chose its own moves and bomb drops, and Astra was the last one standing.

A researcher released a preprint on Chair44, a strongly aperiodic monotile for three-dimensional Euclidean space, saying OpenAI Astra found it using Six Birds Theory.

A leak claims GPT-6 Sol could go live on September 17, processing 30K tokens in about 4 minutes versus 18 minutes for Astra, pitched for all-day high-frequency use.

A full Codex tutorial with chapter navigation covers skills, plugins, sub-agents, scheduled tasks, record and replay, and computer use, noting that skills and sub-agents work differently under Astra.

An OpenAI developer blog post argues that skill triggers and rules from older models are redundant for GPT-6 Astra, and the author recommends running a skill audit with ChatGPT.

The top three on the OrcaRouter composite leaderboard are all OpenAI models, with GPT-6 Astra at 74.0 in third behind GPT-5.4 Pro and GPT-5.6 Luna, followed by Claude Opus 5.

The author says a few complex long tasks on Astra exhaust a week's quota, and that rationing usage limits creativity, so people earning with AI should go straight to Pro.

Compared with GPT-5.5 and DeepSeek-Flash across sim and real robots, humanoid high-level control, dexterous piano playing and in-context learning, Astra shows strong semantic and spatial understanding but weak physical commonsense.

The poster says both of their $200 accounts nearly hit the weekly Codex limit within two days on the same project and workload, even while using Astra on Low mode without Fast.
