Summary

In this video, Ludo Salenne discovers and tests Claude Fable 5, Anthropic’s latest AI model, comparing it with Opus 4.8 and GPT-5.5. He conducts five practical tests: creating a mini app, a game, a website, a dashboard, and an ultimate test. He uses Claude Code for Fable 5 and Opus 4.8, and Codex for GPT-5.5. The tests are performed in one shot, and he evaluates the results based on user experience, design, and functionality. He notes that Fable 5 uses his brand guidelines via a skill, which improves the design. He finds Fable 5 superior to Opus 4.8 in most tests, but comparable to GPT-5.5 in some. He also discusses the higher price of Fable 5 and questions whether it is worth it. The video includes chapters and a promotional segment for his training and community.

Critical Evaluation

The video provides a practical, hands-on comparison of three leading AI models, focusing on real-world application development. The creator demonstrates each test live, showing the actual outputs and his spontaneous reactions, which adds authenticity. However, the evaluation is subjective and lacks rigorous methodology: no controlled variables, no repetition, and no statistical analysis. The tests are limited to front-end development tasks, which may not represent the full capabilities of these models. The creator’s bias towards Claude is evident, as he highlights Fable 5’s strengths while downplaying its weaknesses. The sources cited are only his own training and community links, which are not independent. The video is well-structured with clear chapters, and the creator’s enthusiasm is engaging. However, for a scientific evaluation, the lack of objective metrics and the promotional nature of the content reduce its reliability. The title is somewhat clickbait, but the content does deliver a discovery and test of Fable 5. Overall, the video is informative for a general audience interested in AI capabilities, but it should be viewed as an opinion piece rather than a rigorous scientific analysis.
