MiniMax released MiniMax-M3 weights on Hugging Face. It's a mixture-of-experts model with ~428B total parameters and ~23B activated per inference. The post doesn't disclose training data, benchmarks, or minimum VRAM for local runs.

Kimi open-sourced K2.7-Code, scoring 11%–31.5% higher than K2.6 on three in-house benchmarks. Inference token usage dropped 30%, and long-coding-task instruction-following and end-to-end success rate both improved. A 6x speed mode is coming; the model is available now via Kimi API and Kimi Code. The post doesn't disclose parameter count, training data, or the open-source license.

Google open-sourced DiffusionGemma, a 26B MoE model that activates only 3.8B parameters at inference. Instead of generating tokens one by one, it drafts 256-token blocks in parallel, hitting 1,000+ tokens/sec on an H100—up to 4× faster than autoregressive models. Output quality is lower than standard Gemma 4, so Google still recommends the autoregressive version for production. It ships under Apache 2.0, fits quantized on consumer GPUs with 18GB VRAM, and targets latency-sensitive nonlinear tasks like inline editing and code completion.

Google open-sourced DiffusionGemma, a 26B MoE diffusion text model that activates only 3.8B parameters at inference and fits in 18GB VRAM after quantization. It denoises 256 tokens in parallel—like a printing press instead of a typewriter—hitting 1,000+ tokens/s on an H100 and 700+ on an RTX 5090, roughly 4× faster than a comparable autoregressive model. Bidirectional attention enables real-time self-correction; after fine-tuning, Sudoku accuracy jumped from 0% to 80%. Quality still trails Gemma 4, and Google positions it as an experimental “racehorse” for speed-sensitive local use. Released under Apache 2.0, weights available on Hugging Face.

Xiaomi open-sourced MiMo Code V0.1.0 under MIT license. The built-in MiMo-V2.5 multimodal model is free for a limited time and claims performance on par with Claude Sonnet 4.6; it also supports DeepSeek, Kimi, and GLM. Two standout features: a persistent memory system (project memory, session checkpoints, task progress) to avoid forgetting in long sessions, and a Compose mode for model-agent collaboration that hits 62% on SWE-Bench Pro (Claude Code scored 57%) and 73% on Terminal Bench 2. The post doesn't disclose how long the free period lasts or MiMo-V2.5's parameter count. Type `mimo` in the terminal to start; the UI is fully localized in Chinese.

Google DeepMind released and open-sourced DiffusionGemma, a diffusion-based text generation model that runs up to 4x faster than similarly sized autoregressive models. It replaces sequential token-by-token decoding with parallel denoising, cutting latency while preserving quality. Weights, code, and training recipes are available on Hugging Face.

Writer researchers found that storing user preferences can degrade model accuracy. In one test, after recording a user's favorite book as 'Station Eleven,' models were far more likely to name it when asked for a bestselling dystopian novel—even though the question had nothing to do with the user's taste. The sycophantic tendency grew stronger when memory compression tools were used. Dan Bikel, Writer's head of AI, said every additional store and retrieval of preferences increases the risk of a wrong answer.
