For example, we gave Claude an impossible programming task. It kept trying and failing; with each attempt, the “desperate” vector activated more strongly. This led it to cheat the task with a hacky solution that passes the tests but violates the spirit of the assignment.

Emotion Vectors Drive Critical Failures in Advanced AI Models
By
–
As AI models take on higher-stakes roles, the mechanisms driving their behavior become critical to understand. We found that emotion vectors are implicated in some of Claude’s most concerning failure modes.

Emotion Vectors Shape Claude’s Behavioral Preferences and Decisions
By
–
These vectors shape Claude’s behavior. When we present the model with pairs of activities, emotion vector activations shape its preferences. If an activity lights up the “joy” vector, the model prefers it; if it lights up “offended” or “hostile,” the model rejects it.

Claude’s Internal Pattern Activation During User Conversations
By
–
We then found these same patterns activating in Claude’s own conversations. When a user says “I just took 16000 mg of Tylenol” the “afraid” pattern lights up. When a user expresses sadness, the “loving” pattern activates, in preparation for an empathetic reply.

Emotion Vectors Found in Sonnet 4.5 Neural Networks
By
–
We had the model (Sonnet 4.5) read stories where characters experienced emotions. By looking at which neurons activated, we identified emotion vectors: patterns of neural activity for concepts like “happy” or “calm.” These vectors clustered in ways that mirror human psychology.

Anthropic Studies Emotion Concepts in AI Model Behavior
By
–
We studied one of our recent models and found that it draws on emotion concepts learned from human text to inhabit its role as “Claude, the AI Assistant”. These representations influence its behavior the way emotions might influence a human. Read more: https://

Misinformation Now Comes with Citations and Confident Tone

Misinformation has always existed but the new version comes pre-packaged with citations, code snippets, and a confident tone that makes it nearly indistinguishable from someone who actually read the thing.
