Track anything cheaply: Astra + SAM 3 pipeline cuts tokens 26x
deepakns · x · 2026-09-15
AlexBodner wired Astra and SAM 3 together for cheap 'track anything': Astra names the target in a complex scene, SAM 3 carries it through frames, and Astra is re-called only when the answer expires — 4 calls across 150 frames, 20k tokens instead of 760k. Another dev notes this was an 8-person course project two years ago; now one person with AI can do better.
