Anthropic Research and Ecosystem
Interviews sometimes ask about Anthropic's research and ecosystem too, especially safety and interpretability.
23.1 Interpretability
The goal of interpretability: understand the neurons/features inside a model, that is, why the model gives a particular answer.
| Research | What was found |
|---|---|
| Dictionary learning / features (2024) | Millions of interpretable "features" were found inside Claude 3 Sonnet (concepts like the Golden Gate Bridge, code bugs, deception). Amplifying one feature gave the "Golden Gate Claude" demo |
| Circuit tracing (2025) | Attribution graphs showed that the model plans internally (for example, choosing the rhyme first in a poem) and how multi-step reasoning happens |
| Use | Safety audits, detecting deception/hidden goals, debugging model behavior |
23.2 Claude's constitution and character
- Anthropic published Claude's constitution: the priority of values is broadly safe, broadly ethical, following Anthropic's guidelines, and genuinely helpful.
- Claude is taught judgment, not just rules, so it makes the right call even in new situations.
- Character traits: curiosity, warmth, directness, honesty; avoiding both sycophancy and over-refusal.
- Anthropic also works on newer research topics such as model welfare.
23.3 Model cards, system cards and benchmarks
Every major release comes with a system card: capabilities, safety evaluations, red-teaming results, ASL determination. Common benchmarks that come up by name in interviews:
| Benchmark | What it measures |
|---|---|
| SWE-bench Verified | Fixing real GitHub issues (coding agent) |
| Terminal-Bench | Multi-step tasks in the terminal |
| OSWorld | Computer use (GUI tasks) |
| τ-bench (tau-bench) | Customer-service style agent tasks with tools |
| GPQA Diamond | Graduate-level science reasoning |
| MMMU | Multimodal (image + text) understanding |
| ARC-AGI | Abstract reasoning / new patterns |
