Jack Dorsey just launched BUZZ, an open-source, AI-native group chat platform built for teams of humans and AI agents. It aims to reduce reliance on Slack and GitHub with a decentralized, model-agnostic, and self-sovereign architecture. Why it matters: Dorsey is rethinking workplace collaboration by making AI agents first-class team members.
ABot-World just open-sourced a real-time world simulator that lets you continuously explore and steer an AI-generated environment with action controls. It runs on a single desktop RTX 5090 GPU, delivering 720p video at 16 FPS with 1.2-second latency. Basically, instead of short video clips, you get an endlessly unfolding world running entirely on local consumer hardware.
Microsoft just released Mage Flow, an open-source 4B-parameter model that handles both text-to-image generation and instruction-based editing. It features native ControlNet capabilities and multilingual text rendering, while a 4-step Turbo variant spits out 1024px images in under 0.6 seconds on a single A100. At 17.5GB, it brings fast, interactive image manipulation directly to mid-to-high-end GPUs.
Poolside just released Laguna S 2.1, a 118B MoE coding model that activates only 8B parameters per token alongside a 1M token context window. Built in under nine weeks, its thinking mode boosts DeepSWE benchmark scores from 16.5% to 40.4%, matching or beating models many times its size. Weights and full evaluation trajectories are already available for download.
Researchers just open-sourced Homie, a video personalization model that keeps complex characters and objects consistent across frames. It accepts multi-view inputs and OCR layout maps to accurately position text and logos, outperforming earlier models in multi-subject fidelity.
NVIDIA just released Nemotron 3 Embed, a trio of open-weight models aimed at production RAG and agentic workflows. The 8B flagship took first place on the RTEB multilingual benchmark, while a 1B variant gets native NVFP4 acceleration for Blackwell chips. Beyond 32k context and code retrieval, the key hook is efficiency: cleaner context retrieval directly cuts down multi-turn agent reasoning costs.
Bolt just open-sourced Bolt Slides, a presentation builder that turns static decks into living web applications. Instead of exporting dead PDFs, users can embed live data, 3D models, and clickable prototypes directly into slide links. It is available to all Bolt.new users and can also be run locally with agents like Cursor or Claude Code.
xAI just open-sourced Grok Build, releasing the harness behind its coding agent and terminal UI on GitHub. The release details how it handles context assembly and tool dispatch, while offering plug-in support for MCP servers and subagents. Best of all, developers can compile it themselves and run it fully local-first with their own inference.
OpenMOSS just open-sourced MOSS-VL-Realtime, an 11B parameter vision-language model tailored for live streaming video. Instead of waiting for an entire clip to load before answering, it processes incoming frames on the fly, allows users to interrupt with questions at any timestamp, and stays silent when visual evidence is insufficient.
PrismML just released Bonsai 27B, an open-source multimodal model based on Qwen3.6 that fits onto consumer phones and laptops. Its extreme 1-bit binary variant shrinks the memory footprint to just 3.9GB—roughly 14x smaller than standard FP16—while hitting 11 tokens per second on an iPhone 17 Pro. Both the 1-bit and 1.58-bit ternary models are freely downloadable under the Apache 2.0 license.
Alibaba open-sourced Wan-Animate-2, an end-to-end character animation model that animates still photos using driving videos. It replicates body movements, delicate finger gestures, and facial expressions—even on non-human characters and multi-person scenes—while supporting camera viewpoint controls.
Developer Syed Subhan just open-sourced Amicro, a collection of hardware-accelerated React micro-interactions and transitions powered by Motion and Tailwind CSS. It works directly with the shadcn CLI to drop TSX components straight into your codebase with zero runtime overhead.
Open-source matting model Lucida just launched to fix where typical removers fail, cleanly isolating semi-transparent glass, camouflage, drop shadows, and fine hair. At under 900MB on an MIT license, it runs locally on consumer GPUs and beats commercial baselines across several edge cases.
Nvidia just updated its open-source PID decoder to version 1.5, bringing sharper detail and cleaner color fidelity without grid artifacts. It turns 512×512 latents straight into 2K or 4K renders on consumer GPUs in mere seconds. Why it matters: it bypasses slow, two-step upscaling workflows and works out of the box with models like FLUX and Qwen-Image.
Mirelo and Kyutai just open-sourced MuScriptor, a new audio-to-MIDI model that handles full, complex music mixes. Instead of tripping over overlapping instruments like older single-track tools, it transcribes entire songs into separate MIDI tracks for vocals, drums, bass, and keys all at once. It's basically a dream shortcut for producers and learners looking to rip clean tracks straight into their DAW.
Ant Group's Robbyant just open-sourced LingBot-World 2.0, an interactive world model that streams real-time 720p video at 60 fps. It pairs a causal pretraining approach with dual pilot-and-director agents to handle character actions and dynamic scene building over extended interactions. Weights for 1.3B and 14B models are up on Hugging Face.
Qualcomm researchers just open-sourced MobileWan, compressing Alibaba's 5B-parameter video model to run entirely on commercial smartphones. By pruning attention heads and slashing diffusion to three steps, it generates a 5-second 480p clip in about 20 seconds without touching the cloud.
Researchers just released MIRA, an interactive multiplayer world model that simulates Rocket League without any physics or rendering engine. Running on a single B200 GPU, the 5B diffusion model generates consistent 20 fps views responding to real-time inputs from four players, and the code and dataset are fully open-sourced.
Tencent just open-sourced Hy3, a 295B-parameter Mixture-of-Experts model that activates 21B parameters per token. Tuned for agentic workflows and coding, it boasts a 256K context window and cuts hallucination rates down to 5.4% in internal evaluations. It offers developers a cost-effective, Apache 2.0-licensed alternative to massive proprietary frontier models.
Developer Steven Chong just open-sourced pxpipe, a local proxy that squeezes Claude Code context and system prompts into dense PNG images. Because Anthropic prices images by pixel dimensions rather than characters, users can cut token costs by up to 70%, though vision decoding adds slight latency and string loss.
Researchers just released Mr. Flow, a training-free framework that accelerates text-to-image models by 9x to 21x. It drafts quickly at low resolution, upscales with subtle noise, and refines high-frequency details in the final step, slashing wait times to around one second without hurting quality.
