When most of the AI industry is racing to build ever larger models, Cactus Compute has gone the other direction. Needle2 is an open 45M parameter model that fits into a single 14MB binary, designed for tool calling, device use, and structured extraction on edge devices. The bet is simple: turning on a light or locking a door doesn't require a frontier model with billions of parameters. It requires a model that can map a messy sentence to a function call with the right arguments—a task that needs no world knowledge or open ended prose. That smaller formulation is what makes Needle2 possible, and it's a bet that challenges the industry's assumption that bigger is always better.
