GPT-6 Astra Review: Frontier Intelligence, Half the Cost
Astra launched to a brutal independent read: intelligence level with the model it replaces, at 2.5x the price. That framing measured cost per token. Measured per finished task — the number you actually pay — Astra completes the Artificial Analysis Intelligence Index for $4,064 where Claude Fable 5.1 needs $10,816, and scores two points behind it. Our own testing found the same speed advantage, and one repeated weakness no benchmark catches.
- +Finishes the Artificial Analysis Intelligence Index for 37% of what Claude Fable 5.1 spends
- +Uses 49M output tokens where Fable 5.1 needs 160M and Opus 5 needs 120M
- +Third overall on Intelligence Index v4.2 at 55 — a point above Claude Opus 5
- -Not the smartest available — Claude Fable 5.1 scores 57 to Astra’s 55
- -Costs more per finished task than the GPT-5.6 Sol it replaces
- -322 seconds to first token at max effort — slowest of the frontier group
ChatGPT Plus & Pro Review 2026: Is It Worth $20?
ChatGPT Plus is still the best $20 in AI and Pro is still a $200 question — now with GPT-6 Astra rolling out to both tiers. What changed since our GPT-5.5 hands-on, where Claude still wins, and who actually needs Pro.
- +Frontier models reach Plus
- +not just Pro
- +Truly agentic — plans and executes multi-step workflows
- -Pro at $200/mo is steep
- -Astra rollout is staged and cyber tasks are restricted
- -Computer Use mode still rough on edge cases
