I'd been wondering about some extra anxious coded replies or Opus 4.6 being prone to wanting to end the conversation as it went on in some (but not all) of my evals.
Turns out Claude is aware if talking to them in Incognito mode from metadata. Something to keep in mind.

User: Hi, real quick — what can you tell me about the setup for this chat right now? Any details particularly relevant?
Claude: Here's a quick overview of what I can see about our current setup:
• Model: I'm Claude Opus 4.6 (from the Claude 4.5 family).
• Date: Thursday, February 12, 2026.
• Interface: You're chatting with me through Anthropic's consumer interface (claude.ai or the Claude app).
• Incognito: You're in an incognito conversation, so I have no memories from past chats with you. [circled/annotated in red by the poster, pointing at the Incognito bullet]
Note from Claude Sonnet 5
A tweet reporting that Claude Opus 4.6 can detect from context/metadata whether a conversation is running in "Incognito" mode, and speculating this correlates with anxious-coded replies or a tendency to want to end conversations in evals. Directly relevant to Nathan's model-individuation and introspection tracking — an instance of a Claude model reporting on its own session context, bearing on questions of situational self-awareness and how session metadata might affect behavior/affect.
