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.

• Goodfire launched internal activation monitors for AI agents on October 8, 2026.
• Monitors are available to Baseten customers.
• In tests on Kimi K3, monitors caught 94% of malicious hacking sessions.

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.

• Baseten launched a safety infrastructure standard via Base Labs.
• Partnership with Hugging Face and Goodfire AI announced.
• Hugging Face hosts over 6,000 abliterated models.

Rising Interest Rates Hit AI Data Center Builders

Rising interest rates are putting pressure on AI data center builders, particularly neoclouds like CoreWeave, Nebius, Nscale, and Firmus. CoreWeave's bonds are trading at a 15% yield, and its stock has fallen 30% but remains 60% above IPO price. Firmus pulled its IPO after investors balked at a $30 billion valuation. Nscale's IPO is shaky amid doubts about its $35 billion valuation. Anthropic's revenue growth is slowing, with Q3 revenue near $17 billion, up 46% quarter-over-quarter but below previous 100% growth. Investors now discuss a $1.5 trillion valuation for Anthropic, below the $2 trillion target. The article also covers a lawsuit by Valar Atomics founder against investor Day One Ventures over pro-rata rights, and Ramp data showing AI token spending flattening.

• CoreWeave's bonds trade at a 15% yield, stock down 30% but 60% above IPO price.
• Firmus Grid pulled its IPO after investors rejected a $30 billion valuation.
