What you'll learn

Opus 5 outperforms Fable 5 on many coding tasks at half the cost per token
Real-world workflow testing with bug fixes, landing pages, and research provides better insights than benchmarks alone
Token consumption, costs, and speed vary significantly per task, so choose your model based on your own use cases

Frequently asked questions

What are the main differences between Claude Opus 5 and Fable 5?

Opus 5 benchmarks better on many coding tasks and costs approximately half per token. The video tests both models on identical real-world workflows to determine which performs best for coding, bug fixes, content creation, and other applications.

How are the models compared in this test?

They are tested with identical prompts across various tasks including bug fixes in large codebases, building landing pages, audience research, coding simulators, and more. Each test measures costs, time, and token consumption.

What tasks are tested in the comparison?

The tests include bug fixes in code, building landing pages, writing LinkedIn posts and carousels, creating audience research reports, video outlines, slide decks, computer use snake games, and building simulators.

How do you decide which model to use?

The video shows that token consumption, costs, and speed vary per task. You select the best model based on your specific workflows and which is most efficient for you in terms of cost and performance.

I gave them the same prompts across a bunch of experiments, from fixing bugs in a big codebase to building a landing page, running audience research, and coding a structural simulator. For every run I break down the cost, time, and tokens so you can figure out where each model fits in your own workflows.
