Choosing between Claude and GPT for a biology task starts with knowing where each fails. @LatchBio builds benchmarks that test AI agents on real biological data, making those failure modes visible so scientists can make more informed choices about models and prompts.

Arjun Banerjee (@arjunomics) is joining Reactorfield for a hands-on introduction to benchmarking for scientists: when you need one, how to build your first, and how to test whether a change to your workflow actually improves results.

Scientific workflows often involve unpublished results, proprietary methods, and sensitive data. @getopenwork lets teams build AI workflows with self-hosted open-source models on infrastructure they control. They can then share AI skills and tool connections across the lab, so colleagues can reuse those workflows.

Ben Shafii (@benjaminshafii ), founder of OpenWork, is joining Reactorfield to explore how scientists and deep tech teams can bring AI agents into everyday research, with a focus on handling confidential data and building workflows the whole team can use.

Juan Benet (@juanbenet) looked at YC and saw a model for accelerating science. He began turning Protocol Labs into a network of independent teams, connecting scientists making discoveries with the builders who could turn them into useful tools and products.

We’re welcoming Juan, founder of @protocollabs, to Reactorfield for a 30-minute fireside on how to build an environment where science moves faster.

We’ll explore how to choose problems that unblock other researchers, what teams gain from working together, and where AI can help turn promising ideas into work others can build on.
