Grok 4.3: Elon Musk’s AI Monster?

What it does

What if Elon Musk quietly launched one of the most powerful AI systems yet?. Grok 4.3 introduces native video understanding, automatic PowerPoint/PDF generation, agentic task execution, and a massive 2M-token context window. In our real-world tests, it feels less like a chatbot and more like an AI employee. But beneath the hype, users are reporting memory wipes, instability, and major growing pains. Is Grok 4.3 the future… or still an unfinished experiment?

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  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…
