## Summary

This video compares two hypothetical AI models, GPT-6 Astra and Claude Fable 5.1, across various benchmarks and real-world tasks. It highlights that the best AI model depends on the specific use case, as each model excels in different areas.

### Key Points

- **The Setup** [00:03] — Sam uses GPT-6 Astra for complex math and terminal automation, while Tom uses Claude Fable 5.1 for app interfaces and code review.
- **Astra's Benchmarks** [00:17] — Astra scores 97.6% on Frontier Math Tier 4 vs Fable's 87.8%, and 57.9% on Terminal Bench 4.0 vs 55.8%. OpenAI claims Astra is 63% cheaper per task.
- **Fable's Strengths** [00:45] — Independent testing by Artificial Analysis gives Fable 66 points vs Astra's 61. Fable also scores higher on Humanities last exam with tools (65% vs 57.2%) and app building (74/80 vs 72).
- **The Swap** [01:01] — Sam's dashboard looks outdated, while Tom struggles with his tasks. When they swap projects, both realize they should have chosen the model that fits their work.
- **The Lesson** [01:14] — Don't choose an AI model based on its name; choose the one that fits your specific work.

### Conclusion

The video concludes that there is no single 'best' AI model; the right choice depends on the task at hand. It encourages viewers to evaluate models based on their specific needs.

## Transcript

but completely different results. Meet Sam and Tom. Sam chose GPT-6 Astra for complex math problems and terminal automation, while Tom picked Claude Fable 5.1 to build app interfaces and review code. So, who made the better
numbers. On Frontier Math Tier 4, Astra scored 97.6% compared to Fable's 87.8%. On [snorts] Terminal Bench 4.0, Astra also took the lead with 57.9% against
55.8%. OpenAI even claims Astra cost around 63% less per task on that test. [music] But, don't count Fable out just yet. According to independent testing by Artificial Analysis, Fable scored higher
>> with 66 points compared to Astra's 61. It also performed better on Humanities last exam with tools, scoring 65% against Astra's 57.2%. And when it came to building apps, Fable scored 74 out of 80, while Astra managed
72. Fable also maintained its edge in front-end design. Now, here's the funny part. Sam's dashboard looked like a website from 2009, while Tom struggled >> [music] >> So, they swapped projects, and suddenly
everything made sense. Both had the same reaction, "Why didn't we do this from don't choose an AI model just because of its name. Choose the one that fits your its name. Choose the one that fits your work. So, are you team Sam or team Tom?
