Biotech startup Exin Therapeutics says an AI agent built on Anthropic's Sonnet model independently selected a gene therapy vector, dosage and brain target from 19 candidate treatments to address seizures in a mouse model of epilepsy, then operated a motorized stereotaxic rig to inject the therapy while monitoring for bleeding via camera. CEO Gabriel Ocana-Santero documented the procedure on X, noting a licensed veterinarian supervised with a physical kill switch at every irreversible step, and the mouse reportedly recovered and was seen moving normally afterward.

Anthropic launched Sonnet 5.5, a faster and lower-cost model that it says outperforms its predecessor at coding, task completion and document creation. The release follows last week's launch of the pricier Opus 5.5, with a cheaper Haiku 5.5 model still to come. Anthropic said Sonnet 5.5 does not push the frontier of model capability, but includes improved cybersecurity safeguards compared to earlier Sonnet versions.

Anthropic has released Sonnet 5.5, an update to its mid-tier AI model that the company says runs 30 percent faster than its predecessor and burns tokens more slowly, cutting costs. Anthropic says the model outperforms its more powerful Opus 5.5 on agentic coding benchmarks and now carries cyber capabilities strong enough to trigger the same safeguards applied to its Fable and Opus models. The company also says a refreshed version of Haiku, its smallest model, is coming in the next few weeks.
