Claude’s new top model, Fable 5.2, came out on Nov. 9. A model is the AI that writes Claude’s answers. Claude has several, and Fable is the most capable one. If you pay $20 a month for Claude Pro, it’s included in your plan right now, but only through Monday, Nov. 16. It also doesn’t switch on by itself. Here’s who gets it, the taps that turn it on, and what happens after Monday.
Who gets Fable 5.2
Anthropic, the company that makes Claude, set out the rules on its launch offers page. They depend on your plan:
- Pro ($20 a month) and standard Team seats: Fable is included for one week, through Nov. 16 at 11:59 p.m. Pacific time. You can spend up to half of your weekly usage limit on it. That limit is how much you can use Claude in a week on your plan.
- Max, Ultra and premium Team seats: Fable is a regular part of the plan, also for up to half of your weekly limit.
- Free: Fable isn’t available.
How to turn it on
We checked these steps in the Claude app on an iPhone on Nov. 10. Claude was still set to its usual model, Opus 5.5, until we changed it.
- Open a new chat in Claude.
- Tap the model name under the message box. Ours said Opus 5.5.
- Pick Fable 5.2 from the list.
Paid plans also get a free reset, which refills your Fable limit if you run out. To claim it:
- Go to Settings, then Usage.
- Under Limit resets, tap Reset for free.
How many resets you get depends on your plan. Pro and standard Team seats get one, and it expires on Nov. 16. Max, Ultra and premium seats get one to three, based on how long you’ve been a paying subscriber: one if it’s under six months, two for six to 12 months, and three for more than a year. Those expire on March 8, 2027.
One limit to know: resets only go to accounts that already had a paid plan before Nov. 9 at 10 a.m. Pacific. If you subscribe today, you won’t see the button.
What changed in Fable 5.2
These are Anthropic’s own claims from its announcement. We haven’t measured them ourselves.
- It’s faster. Anthropic says testers got answers up to 30% faster than with the last version, Fable 5.1.
- It stops fewer harmless requests. Fable has safety filters that block some questions in areas like cybersecurity and biology. Anthropic says the new version had about 55% fewer of what it calls unnecessary blocks.
- It’s better at coding, reasoning and reading images, according to Anthropic.
There is also a version called Mythos 5.2 without those filters. It’s only for organizations Anthropic has vetted, so you won’t find it in the regular app.
What to know before you switch
- For Pro, this is a one-week trial. After Nov. 16, Fable runs on usage credits, which means you pay extra for what you use on top of your $20.
- Fable uses up your limit faster. Anthropic says Fable models draw from your regular weekly limit and use it faster than other Claude models.
- Anthropic itself points most people to a different model. Its announcement says: “For most coding and knowledge tasks, we recommend that users start with Claude Opus 5.5.” In the app, Opus 5.5 is labeled “For complex work and everyday tasks,” and Fable 5.2 is labeled “For your toughest challenges.”
- Check your usage credits setting. If you’re on Pro and don’t want extra charges after Monday, switch back to Opus 5.5, and look at the Usage credits switch under Settings, then Usage.
The bottom line
If you’re on Pro, this week is the time to try Fable 5.2 on your hardest task, because it costs nothing extra until Monday. For everyday questions, the model you already had is the one Anthropic recommends. If you’re on Max, Fable is already part of what you pay for. If you’re on the free plan, there’s nothing to turn on.
