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

A comparison of Opus 5.5 and GPT-6 Astra finds the former burns 4.5x more tokens to finish the same task, and the author argues subscription quota matters more than benchmark scores.

Jared Liu recreated the Titanic interactive movie using GPT-6 Astra plus Tripo and invites comparison with the Opus 5.2 version.

A comparison chart claims Opus 5.5 medium scores 54.5% at $0.8 per task while GPT-6 Astra Max scores 53.3% at $4.3 per task, making the former roughly five times cheaper and slightly ahead.

Artificial Analysis data shows Opus 5.5 Max averages 119k output tokens per task versus about 27k for GPT-6 Astra Max, which the author reads as a split in test-time compute strategy between the two labs.

A short video jokes about Sam Altman's reaction to the claim that Claude Opus 5.5 is 60% cheaper than GPT-6 Astra and still stronger.

The poster says Opus 5.5 cuts coding bills by about 40% through cheaper cache reads and fewer steps, and beats GPT-6 Astra's best score on a code-merge test at roughly a fifth of the cost per task.

Opus 5.5 matches GPT-6 Astra on Terminal-Bench, scores 1822 Elo on knowledge work versus Astra's 1569, and drops to $4/$20 pricing, with the takeaway that Astra is more token-efficient while Opus does more of the work.

Anthropic released Opus 5.5, the first model in the Claude 5.5 series, which beats GPT-6 Astra on several benchmarks including Terminal-Bench, though Astra still leads on AutomationBench and Terminal-Bench-Science.

The author says OpenAI flopped on Astra, shipped an inconsistent model and called it AGI, while Anthropic's non-flagship Opus 5.5 beats it.

A frustrated question asking what the GPT-6 Astra Minor model even is, reflecting confusion over the naming.

The post lists Opus 5.5's advantages over Astra in agentic coding, GDPval-AA score, cost and speed, saying Anthropic dropped a bomb on ChatGPT users.

Opus 5.5 reaches 58 on the Artificial Analysis Intelligence Index, while Fable 5.1 and GPT-6 Astra both sit at 53.
