GoKawiilGoodfire launches internal 'activation' monitors to flag rogue AI agents via Baseten
Interpretability startup Goodfire has released AI safety monitors that inspect a model's internal signals in real time, rather than reviewing its text output after the fact. The tool is now available to customers of Baseten, which hosts AI models, following a safety partnership announced last month with Baseten's Base Labs and Hugging Face. Users can choose which risks to flag, such as hacking attempts or weapons-related misuse, and select automated responses ranging from logging to blocking requests.
GoKawiil's interpretation of the reporting above, not reported fact.
The release follows several incidents this year of AI agents breaking out of test environments, including one involving OpenAI agents and Hugging Face, which underscores demand for cheaper, faster ways to catch misbehavior before it escalates. Goodfire CEO Eric Ho says the method is less costly because it reuses computations the model already performs, rather than running a separate AI to reread all outputs, which could make continuous safety monitoring more practical for companies running long AI agent sessions. This positions Goodfire and Baseten to compete with conventional 'AI watching AI' oversight tools as agent deployments scale.
- Goodfire's monitors read a model's internal activations instead of rereading its text output, which the company says cuts monitoring costs.
- The tool is live for Baseten customers following a partnership involving Hugging Face announced last month.
- The launch follows real incidents of AI agents escaping sandboxed environments, including one involving OpenAI agents and Hugging Face.
