About me: So I have been a Claude Code user since the launch, prior to that I was using Cursor. I use it in an enterprise setup, building on our existing codebases, like fixing bugs, adding features, etc. I tried Fable after so much talking going on here at Reddit for 2 things. A: A new feature on the existing codebase. B: A greenfield small-scale project. By the end of both, I have hit my Max20 limits, which I have never hit 25-35% in a week. My observations:
- The model may be great, but I don’t know what is different from Opus. Opus 4.6 was great. It was diluted with 4.7 and 4.8, and everything became dumber. Right now, Fable feels like what would have actually become Opus 4.7 or Opus 4.8 if they delivered incremental performance.
- In order to compare Fable and competing models, I took a simple business question, like whether charging X amount of money for Y service is good. I ran it on Opus 4.6, Opus 4.8, Sonnet, Fable and DeepSeek Expert (Pro, I guess) with web search and maximum thinking, and to be honest, I liked DeepSeek better. Fable was similar to DeepSeek, but at a price tag that doesn’t justify it. The way I see it, Fable is built for people who want to prompt once and pray that a complete greenfield project is done in one shot. There is no way anyone can verify that things are working in such builds. Even if you set up an Agent + Playwright to do browser-level tests, it is going to take weeks to test that build. I am also worried that this is going to set a wrong precedent. Because this incentivises Anthropic to dilute Opus and Sonnet even further in value to push people to pay per credit for Fable, because if they do dilute, there is no way vibe-coders can immediately write code on their own (including me, as I will have to brush up my skills) and they will be forced to bite the bullet and pay extra. If that happens, I hope Anthropic does remember that open-source models do exist. Just as a measure to stay safe when shit hits the fan, I have started exploring OSS models for coding work.
