Perseus
ActiveAI-nativeApplied Lab focused on Search in Latent Spaces.
What it does
Perseus takes an iterative branching approach to search in high dimensional spaces. Our first product helps coding agents find the right codebase context before they write. It searches files, symbols, and dependencies in parallel, so models can make better changes with less trial and error. Perseus Search gives Mythos-level programming ability to Opus-level coding agents.
