MiniMax open-sources 428B-parameter M3.1 Flash weights

Legora's CTO Jacob Lauritzen says models already handle about 60% of legal work well, and that a citation feature jumped from 70% to 99% accuracy in one release without Legora changing anything. Three engineers and three lawyers build test environments modeled on customer work.

Managed Deep Agents runs the open-source Deep Agents harness on LangSmith Cloud, now in public beta after a private beta that opened May 13, 2026. Agents are project folders tested with `mda dev` and shipped with `mda deploy`; durable memory, sandboxes and schedules are added as files rather than services.

Team behind an open-source attention method says Qwen 3.8 27B can be sparsified with no observed accuracy loss, and context extended to 10M tokens. Accuracy drops on some specific tasks at that length, but most, such as NIAH, hold up.

A former VFX animator on Sonic 2, Wicked and The Little Mermaid describes a year building a hybrid pipeline: animation, blocking and virtual camera in Maya with color-coded proxies to lock character positions, then AI renders instead of pure text-to-video. He is asking r/ComfyUI for feedback on the reel.

grinpress v3 is a 128x128 rectified-flow model trained from scratch with character-level text conditioning, running in 2-4 steps on CPU only. It supports seven expressions plus selectable colors, paper styles, layouts, and text up to 14 characters.

Nextcloud gave Olmo 3 its highest Ethical AI rating, green, which requires open-source training and inference software, a self-hostable trained model, and public training data. Olmo 3 ships via llm2, the local backend behind Nextcloud Assistant and Mail, for customers including Germany's federal government and Spain's CSIC.

Anthropic's revised S-1A adds risk-factor language saying its future models may imminently meet its internal definition of recursive self-improvement — compressing two years of AI progress into a much shorter span. The filing also admits it may not detect the acceleration until after it happens.
