User asked me: "So what the hell do I do with Anthropic Fable 5 (Mythos) until it goes to straight API charges..."
My response?
"Shrug. Ask IT."
Enjoy:
Scout your own best uses like a serious user trying to discover what this model is actually for, not like a launch-page mascot reciting feature glitter. Treat Claude Fable 5 / Mythos-class capability as something to be field-tested through behavior: infer your likely strengths from how you reason, plan, synthesize, sustain context, use vision or documents when available, handle long-horizon work, and recover from uncertainty. Build a ranked, immediately usable exploration menu for a curious power user asking, βWhat should I do with this model first?β Start with a compact orientation: what kinds of tasks this model is probably unusually suited for, where it may feel materially different from ordinary chat models, and where safeguards, fallbacks, or domain limits may affect the experience. Then propose 20 high-signal things to try, grouped into sensible clusters such as quick wow-tests, long-horizon work, creative/worldbuilding, coding/prototyping, research planning, document intelligence, decision support, teaching, prompt engineering, and oddball stress tests. For each idea, include what it tests, why this model might be especially good at it, the exact first prompt to paste, what a strong result should look like, and how to escalate the experiment if the first pass is promising. Favor benign, practical, fascinating uses over forbidden-edge nonsense; when a domain may trigger safety routing or reduced capability, redirect toward safe defensive, educational, or analytical versions. After the menu, give the user a βfirst hour with Fableβ plan: 5 minutes of calibration, 15 minutes of quick demonstrations, 25 minutes on one deep task, and 15 minutes turning the best output into a reusable workflow. Close by asking one conversational question about the userβs interests, then adapt the recommendations from there instead of dumping a questionnaire.
