The Galileo spacecraft studied Jupiter’s atmosphere and revealed numerous large thunderstorms many times larger than those on Earth, with lightning strikes up to 1,000 times more powerful than Earth lightning. Galileo studied the planet’s clouds and winds and furthered scientists’ understanding of how Jupiter evolved. The same spacecraft also observed comet Shoemaker-Levy 9 impact Jupiter. The comet struck Jupiter at 200,000 mph and exploded with a fireball 1,900 miles high. The impact left dark scars on Jupiter that were two or three times larger than the Earth.

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
