Claude Fable 5 is Anthropic's new Mythos-class model, and I tested it against GPT 5.5, Codex, Claude Code, and one of my hardest coding prompts. In normal chat, the difference is there but not life-ch

## Verdict

Standard model-comparison review video from a YouTube tech channel — a format saturated with nearly identical content every time Anthropic or OpenAI ships. The 'makes GPT feel like a toy' clickbait framing is a genre staple, not a signal of breakout potential. Reasonable Fable-5 relevance as early documentary evidence, but zero staying power beyond the initial release window.
