Two open-weight models landed this week that every developer needs to know about — and neither comes from the usual suspects.
Xiaomi MiMo: The Smartphone Giant Goes All-In on Open AI
Xiaomi just made its biggest AI play yet. The company's MiMo family — led by the compact MiMo-7B-RL — is now open-weight and free to download. Despite its small 7B footprint, MiMo-7B-RL beats models 4-5x its size on math reasoning (AIME 2025) and code generation (LiveCodeBench v5), surpassing even OpenAI's o1-mini. It's designed as the reasoning engine behind Xiaomi's "Human × Car × Home" ecosystem — meaning your next Xiaomi phone, EV, or smart speaker might run inference locally.
And Xiaomi isn't playing small: CEO Lei Jun pledged $8.7 billion in AI R&D, with trillion-parameter MiMo-V2-Pro already trailing only Claude and GPT on agentic benchmarks.
Poolside Laguna XS 2.1: The Coding Agent for Your Laptop
Meanwhile, Poolside released Laguna XS 2.1 — a 33B total-parameter Mixture-of-Experts model with just 3B activated per token. That means it fits on consumer hardware. It's purpose-built for agentic coding: long-horizon tasks, tool calling, and pull request generation. It's free on Hugging Face and OpenRouter until July 9, when the older XS.2 gets retired.
The kicker? You can QLoRA fine-tune it on a single RTX 4090.
Why This Matters
Both models prove the open-weight ecosystem is accelerating faster than the frontier. Xiaomi brings consumer-hardware-first reasoning; Poolside brings agentic coding for the rest of us. The gap between "open" and "frontier" is now measured in months, not years.
Run them locally. Build with them. The era of exclusive AI APIs is ending.
