Fable 5.2 expands what AI can build
Fable 5.2 Is the Best AI Ever. So Why Am I Not Switching Yet?
The episode tests whether a costly, uneven frontier model signals a new kind of AI use beyond routine productivity.
- 1Fable 5.2 leads across demanding benchmarks, but its high token consumption makes everyday use expensive.
- 2The model’s jagged abilities produce sophisticated software and games alongside tedious, poorly judged, or frustrating results.
- 3Fable 5.2 is best suited to large, open-ended projects, while Opus 5.5 remains more practical for defined tasks.
Don't miss
The episode’s clearest insight is that Fable 5.2 may matter most as “opportunity AI,” enabling ambitious software and game projects rather than routine efficiency.
The brief
Anthropic’s Fable 5.2 arrives with leading results in coding, science, cybersecurity, robotics, and agentic work—but its practical value is harder to measure than its benchmark performance.
The model can consume enormous numbers of tokens and cost far more than routine alternatives, creating a sharp divide between impressive capability and sensible everyday use.
Early testers describe complete software tools, security audits, 3D renders, games, and other ambitious projects, while also reporting ordinary failures and poor judgment.
Ethan Mollick’s “Jagged AGI” framing captures the tension: Fable can produce sophisticated work yet often misses what humans would find tedious, repetitive, or unappealing.
Nathaniel’s conclusion is “opportunity AI”: use Fable for large, creative, open-ended projects, and reserve Opus 5.5 for well-defined efficiency work.

Fable 5.2’s weak understanding of human interest limits its content-work usefulness.
“the model's seeming inability to know what is interesting to humans and what's valuable to us is a real detriment to the type of content work that I might apply it to.”
Listen at 22:34
Fable 5.2 is better understood as opportunity AI than efficiency AI.
“this is a model that really asks us to push ourselves in terms of what we can do. In other words, opportunity AI, not efficiency AI.”
Listen at 25:16
Complete game-building capability may expand AI use cases and users.
“I wonder if the capability to build complete games actually changes what we use them for and the different types of people that leverage them for personal or even professional reasons.”
