Circuit Breaker Labs Tests AI for Psychological Safety

Oct 5, 2026
The startup uses simulated users to test how AI systems handle potentially harmful conversations across languages, cultures, and age groups.

Circuit Breaker Labs uses simulated users to test how AI systems respond to potentially harmful conversations, according to TechCrunch. The simulations represent different ages, backgrounds, languages, cultures, speech patterns, slang, coded language, and typing errors.

The startup works with human specialists to create the simulations, then runs tens of thousands to hundreds of thousands of interactions each day. Its tests examine whether models can detect psychological risks that emerge across multiple conversations and respond appropriately.

Circuit Breaker Labs gives models auditable scores based on the results. The five person company currently tests high risk applications including AI coaching, journaling, and mental health support tools.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
