You picked Claude Sonnet 5.5 — but Anthropic may send your request to Sonnet 5 in “higher-risk” situations
TL;DR
Anthropic has released Claude Sonnet 5.5, which includes enhanced cybersecurity safeguards and model fallbacks for higher-risk tasks, though it remains less capable than its top models. Users may experience more request refusals, particularly in cybersecurity contexts.
✦ Why It Matters
Evaluate your use of Sonnet 5.5 to ensure fallback settings align with your cybersecurity needs.
Key Takeaways
- Enable fallback for Sonnet 5.5 to handle blocked requests effectively.
- Anticipate increased refusals for legitimate cybersecurity tasks.
- Monitor prompt injection vulnerabilities when using fallback.
- Consider enrolling in the Cyber Verification Program for fewer restrictions.
How It Works
Sonnet 5.5 employs a three-stage cyber enforcement system that includes a probe to read internal activations, a lightweight classifier on the model itself, and a separate trained LLM classifier to evaluate and decide on blocking requests. This layered approach helps identify and mitigate harmful cyber requests effectively.
