An Indie Developer's Honest Verdict: Claude's Top Model Burned Over 25% of Session Tokens on a Bug Fix -- Then Opus Nailed It in One Shot
TL;DR · What you'll learn
- 1 A developer who codes his game entirely by hand finally put Claude to the test, after fielding the same 'why don't you use AI?' question from viewers day after day.
- 2 He explains he avoids AI because he's mid-way through a project with a complex structure and wants to keep understanding it fully himself -- but agreed to try it out regardless.
- 3 Fixing two bugs with the top-tier Fable model alone burned over 25% of the session's tokens, raising real doubts about its practicality.
- 4 Out of curiosity, he switched to Opus for the same bugs -- and despite Fable supposedly being smarter, Opus nailed a perfect fix (restoring a deleted check) in one shot, while Sonnet couldn't fix it at all.

The Honest Answer to 'Why Don't You Use AI?'
This indie game developer says he's tired of being asked, almost every single stream on Twitch, whether he's coding by hand and why he doesn't just use Claude Code. He explains that he codes by hand because he's mid-way through a project with a complicated structure and wants to keep a full grasp of how everything works. Viewers sometimes accuse him of being 'a robot racist' for it -- so he decided it was time to actually put it to the test himself.
Fable vs. Opus vs. Sonnet: The Bug-Fix Showdown
Handing two real bugs from his game to the top-tier Fable model alone burned through more than 25% of the session's tokens, he recalls, which raised real doubts about its practicality. Out of curiosity, he reproduced the same bug and switched the model to Opus -- and despite Fable supposedly being the smarter model, Opus delivered a perfect fix in one shot, restoring a check that had been deleted. He also tried Sonnet, which failed entirely, scattering unrelated changes through the code without ever actually resolving the issue.
The Verdict
His overall conclusion: better than expected, but not fully reliable. He won't use it to generate the main code for his own project, but for hunting down bugs -- something that can eat up half an hour of searching for the exact cause -- it can save a lot of time and frustration. Starting a brand-new project entirely by hand from now on would feel like 'going back to the stone age,' he admits, while also warning that leaning on it too much risks losing your grip on your own code to the point you can't add anything without asking Claude first. Used carefully, he concludes, it's a genuine productivity multiplier.
Editor's Take
The most interesting twist here is the reversal: the supposedly top-ranked Fable model burned a huge share of tokens on a simple bug fix, while Opus solved the exact same bug perfectly in one attempt. It's a reminder that a model's rank doesn't necessarily translate into task-level efficiency -- 'just use the top model' isn't automatically the optimal call on cost or accuracy. And the developer's own wariness about losing his grip on the codebase is a perspective worth holding onto in the agentic era: the pursuit of productivity and the preservation of technical self-sufficiency are two values that need active balancing, not one traded blindly for the other.
