The Stack v3 is 114TB of raw code from 224M repos, filtered down to ~5T tokens versus ~550B in v2. C++ grew 15x, TypeScript 7.5x, Rust 7x. It ships file contents inline instead of Software Heritage IDs, so no resolution step before training.
FLUX-mimic puts the FLUX 3 video backbone on robot and wearable data to predict actions, and runs on a single on-prem GPU. The claim under it: a model that predicts video well has already learned enough world model to control a hand.

AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
multi-agent — Using several AI agents on one problem — splitting work in parallel, checking each other, or filling different roles like planner and reviewer.
distillation — Training a small, cheap model to imitate a big one's outputs, keeping much of the capability at a fraction of the cost.
open weights — A model whose trained parameters are published for anyone to download and run — unlike API-only models you can access but never possess.
Why it matters
If you build generative media pipelines, FLUX 3 collapses text-to-video, image-to-video, keyframe interpolation and native audio into one model with agentic chaining for multi-shot sequences, removing the usual stitch-together of separate video, audio and upscaling models. The FLUX-mimic spin-off also signals that video world models are becoming usable as action policies, which matters if you are watching generative models move into embodied control.
