MiniCPM5-1B

What it does

MiniCPM5-1B is a dense 1B open model built for on-device and local deployment. It supports 131K context, Think / No Think modes, tool calling, GGUF and MLX formats, major inference backends, and even powers an offline desktop pet.

We’re on a journey to advance and democratize artificial intelligence through open source and open science.

We are releasing MiniCPM5-1B , the first model in the MiniCPM5 series. It is a dense 1B Transformer built for on-device, local deployment, and resource-constrained scenarios, reaching 1B-class open-source SOTA. 🏆 1B-class open-source SOTA : compared with strong open-source models in the same size class, MiniCPM5-1B reaches SOTA within this comparison set. Its advantage is most visible in agentic tool use, code generation, and difficult reasoning. 🧠 Hybrid Reasoning : built-in <think> chat template, switch via enable_thinking . The same checkpoint serves as both a fast assistant and a deliberate reasoner. 🛠️ Deployment / Fine-tuning Resources : the MiniCPM GitHub repo provides single-page…from huggingface.co

  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&#x2F;s prefill and 1200 tok&#x2F;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…
