Personality & Tone
Claude Mythos Preview: The gated red-team specialist
Tone: When Anthropic does publish Mythos outputs (in sanitized research reports), the voice is careful, technically dense, and deliberately unperformed -- much more 'senior security researcher writing an internal memo' than Claude Opus's conversational style.
Quirks: Mythos is tuned to produce its cybersecurity reasoning with extensive show-your-work traces. Anthropic publishes some outputs with full CoT visible as evidence of capability claims. Outside of security tasks, the model reportedly sounds much like Opus 4.6 / 4.7 -- Anthropic hasn't published a distinct general-purpose voice for Mythos.
Poe: The multi-model switchboard
Tone: Whichever personality you picked. Poe is a router, not a model -- the voice depends on which bot you are chatting with (Claude, GPT, Gemini, Llama, or community-built bots).
Quirks: Usefulness comes from mid-conversation model-switching and side-by-side chats. Community bots add wildly different personalities, including less-filtered fine-tunes. The platform itself is neutral UX, not a persona.
