Anthropic's model family, offered in four tiers that trade speed and cost against depth: Haiku for high-volume work, Sonnet as the balanced option, Opus as Anthropic's recommended starting point, and Fable for the longest, most demanding tasks.

Which one for you

Each line says whether it comes from the provider or is our own judgment from the checked facts. None of it is from our own testing yet.

  • Not sure where to start (developers)

    Opus 5.5. Anthropic says: “If you're unsure which model to use, start with Claude Opus 5.5 for most workloads.”

    Provider saysAnthropic: Models overview (opens in a new tab)

  • High-volume, repetitive jobs

    Haiku 5.5, which Anthropic describes as for classification, extraction and routing. Check it on your own examples first.

    Provider saysAnthropic: Models overview (opens in a new tab)

  • Long, hard tasks where quality matters most

    Fable 5.2 costs twice Opus 5.5 per token. Try Opus first and move up only if its results fall short on your work.

    Our judgment

  • Everyday personal use

    Start on the free app plan; Pro at $20 a month is the first paid step. All four models share a 1M-token context, so the plan's usage limits matter more than the window.

  • Writing

Our draft notes

Put it to work

What changed

  1. 12 Nov 2026Pre-launch re-check. Haiku 5.5's price now shows Anthropic's two bands (up to and above 100K-token prompts). The models page no longer lists cloud platforms, so that line is marked not yet checked. Max plan is $100 a month, not "from" $100.
  2. 11 Nov 2026Claude Fable 5.1 replaced by Fable 5.2 in Anthropic's lineup. Top-tier price now $8 in / $40 out (was $10 / $50).
  3. 11 Nov 2026Added app plan prices from Anthropic's pricing page.
