Goodfire Launches Internal AI Agent Monitors
Goodfire, a startup specializing in AI interpretability, launched on Thursday a new type of AI agent monitor that inspects a model's internal signals rather than reading its output, aiming to detect rogue behaviors more efficiently and at a fraction of the cost. The monitors are available to customers of Baseten, an AI model hosting platform. Baseten's Base Labs had previously announced a safety partnership with Goodfire and Hugging Face. Goodfire's approach uses small probes that scan a model's internal activations at each step, triggering a closer AI review only when flagged. In tests on the Kimi K3 model, Goodfire's monitors caught 94% of malicious hacking sessions and cost about $51 for 1,500 sessions, compared to $233 for a cheaper model and $10,000 for a top-tier one. The company positions the solution for open models, which can be stripped of safeguards, and sees it as critical for inference-time guardrails.
This news introduces a novel and cost-efficient approach to AI agent monitoring, which is critical for the safe deployment of autonomous AI agents in advertising and other industries. It addresses key concerns about rogue AI behavior and offers a scalable solution, potentially accelerating adoption of AI agents.

Goodfire raises $150M to decode AI 'alien brains'
Goodfire, an AI research startup focused on mechanistic interpretability, has raised a $150 million Series B at a $1.25 billion valuation. Co-founded by Dan Balsam (co-founder & CTO), Eric Ho, and Tom McGrath, the company builds tools to inspect and intervene at neuron-level representations inside large models. Goodfire says its work has produced practical outcomes: identifying potential epigenetic biomarkers for earlier Alzheimer’s detection with partner Primmamenta, deploying inference-time interpretability guardrails with partners like Rakuten, and detecting neuronal "hallucination signatures" that can be used as training signals to reduce hallucinations. The interview discloses the host Joe Lazer is a small seed investor in Goodfire and places the company’s approach as a safety- and reliability-focused complement to mainstream LLM scaling efforts.
AI Monitoring AI: The Emerging Solution to Rogue Agents
As AI agents take on longer and more complex tasks, companies are struggling to oversee their actions. The July Hugging Face incident, which involved nearly 12,000 agents, highlighted the need for better monitoring. The emerging solution is to use AI to monitor AI, despite concerns about adversarial interactions. Startups like Braintrust, LangChain, and Judgment Labs have raised significant funding, while Apollo Research launched Watcher, and Goodfire offers Silico, which use internal model signals to detect unwanted behavior. Some experts advocate for detailed logging and network monitoring as more reliable, non-AI-based alternatives.
Baseten, Hugging Face, Goodfire Partner for AI Safety
Baseten's research arm, Base Labs, announced a partnership with Hugging Face and Goodfire AI to establish a safety standard for open-weight AI models. The collaboration aims to develop and publish methods for training and monitoring these models, making safety an integrated feature rather than an afterthought. This comes amid rising concern over 'abliteration,' a technique that removes safeguards from open models, with Hugging Face listing over 6,000 such models. The companies have not detailed technical specifics, but Goodfire's expertise in AI interpretability is expected to play a key role. This initiative seeks to leverage openness as an advantage for safety, providing transparent controls and encouraging community contributions.
