Claude Fable 5.2 vs Opus 5.5: Which Should You Use?

§ TranscriptRead instead

Claude's new top model is out, but don't switch everything to it just yet. Artificial Analysis, an independent group that ranks AI models, scored Claude Fable 5.2 at 65. That's up from 49 in about 10 weeks. Gemini 4 Carbon held the top spot for less than 2 weeks. Then Fable knocked it off. But at its top setting, Fable costs more per task than Opus 5.5. More than double. For most everyday work, Anthropic's own advice is to start with Opus. How much Fable you get depends on your plan. It's on the paid plans: Pro, Max, Ultra, Team and Enterprise. On Max, Ultra and premium Team seats, Fable can use up to half of your weekly limit. On Pro and standard Team seats, it runs on usage credits. Open your usage page and look for free Fable resets. A standard Team seat got one. My Ultra plan got three. Use them before they expire. On Enterprise, Fable chats are kept for 30 days by default for safety checks. If your company can't have chats stored at all, ask Anthropic about the new option. It runs those checks inside your own systems. Finance teams can use it for deep research and forecasts, where small details change the answer. In an early test by Box, it caught salary payments that didn't match a bank statement in a loan file. Opus for the everyday. Fable for the hard stuff. So, which job on your list is too big for your usual chat? Give Fable that one.

§ 01The write-up

Claude Fable 5.2 is the strongest model Anthropic has opened to paid users, and it is also the most expensive to run. This short covers the two numbers that matter and what your plan gives you.

On the independent Artificial Analysis index, Fable 5.2 scores 65 at its top setting, against 59 for Opus 5.5. At that setting it costs about 2.6 times as much per task. That gap is why Anthropic still tells most people to start with Opus and bring Fable in for the long, hard jobs.

Access depends on the plan. Max, Ultra and premium Team seats can use Fable for up to half of the weekly limit. Pro and standard Team seats pay for it with usage credits, once the launch offer ends on 16 November 2026.

For the role-by-role version, with the jobs I give Fable myself and how I make it last the week, read the full guide: Claude Fable 5.2 vs Opus 5.5: which jobs are worth the upgrade.
