Overview
Who it's for
Cactus Needle 3
Developers building AI features into mobile apps, wearables, robots and embedded devices.InstinctFlash
Robotics teams deploying vision-language-action and other robot models on edge and workstation GPUs.Problem
Cactus Needle 3
Most language models are too large to run on small devices, so on-device assistants depend on a network round trip to the cloud.InstinctFlash
Robotics models are slow to serve on edge hardware without custom engines and optimization work.Solution
Cactus Needle 3
A tiny single-binary model that picks the right app functions, fills their arguments, extracts typed fields and returns embeddings entirely offline.InstinctFlash
Purpose-built engines with fused Triton kernels and FP8, exposed through a single Runtime API.What makes it unique
Cactus Needle 3
Cactus says Needle 3 beats models 10x its size on mobile tool calls and that a fine-tuned version passes DeepSeek V4 Flash from 4 layers up.InstinctFlash
Reports up to a 33.78x speedup for LingBot-VA on Jetson Thor, with reproduction instructions.
