Lightfield uses an agent to build Jev classifiers automatically

In a test by Lightfield's Chief AI Officer, Claude Opus wrote classifiers and TypeSafe's Jev ran them, and the agent-built classifiers matched or beat a conventionally fine-tuned model on all six tasks.

Lightfield's Chief AI Officer @vesko_st tested whether an agent can build and maintain the classifiers to do its repetitive work, with Claude Opus writing the classifiers and TypeSafe's Jev running them. When given the same training data, agent-built classifiers matched or beat a conventionally fine-tuned model on all six tasks we tested. Read our latest research to see how agents can hand off repetitive ‘system one’ judgments to classifier models, and how we’re bringing this into Lightfield.
