What happened
no preamble, no acknowledgment..." This is a very strict instruction. Let's look at the section heading instruction: "Then write EXACTLY these five sections, each as '## Heading' followed by two paragraphs of 80–160 words:" If I write:
Is that a markdown heading? Yes, # headings refers to #, `##
How it works
The model supports text and image input, outputs text, and has a 1M tokens context window with knowledge up to April 2026.GPT-6 Astra (max) scores 61 on the Artificial Analysis Intelligence Index, placing it well above average among comparable models (median: 36). When evaluating the Intelligence Index, it generated 42M tokens, which is fairly concise in comparison to the median of 62M.Pricing for GPT-6 Astra (max) is $10.00 per 1M input tokens (expensive, median: $2.00) and $50.00 per 1M output tokens (expensive, median: $10.00).

What to watch next
Cross-check release notes and official docs before changing production systems based on early reporting.
Developer Action Items
- ☐ Diff the official changelog for Anthropic / Claude / Codex 10.00 before you bump — APIs, defaults, and removed flags only.
- ☐ Install through the vendor's documented channel in staging; keep a one-command rollback and time-box the canary.
- ☐ Grep your repo for old flag names, lockfile pins, and plugin versions that the notes mark as breaking.
- ☐ Prefer the first patch cut over the day-zero tag unless you have a reason to be on the leading edge.
- ☐ If HN Claude/Codex/Fable did not name a region, plan, or SKU, screenshot the official availability line before you promise it to users.
