Ornith 1.5 open models match Claude Opus 4.8 on coding benchmarks

An open-source model family just posted numbers that rival one of the most capable closed models in the world — and it's available under an MIT license. Ornith 1.5, released today by the Ornith AI team, is a three-model family spanning 9 billion dense parameters up to a 397 billion mixture-of-experts flagship. The big headline: the 397B MoE scores 86.1 on Terminal-Bench 2.1 (Terminus-2) and 86.0 on SWE-bench Verified, placing it on par with Claude Opus 4.8's 85.0 and 85.8 respectively.

NVIDIA Cosmos 3 — open-source world model for embodied AI

NVIDIA is betting that the future of robotics lives at the edge, not in the cloud. At the RSS 2026 conference in Sydney, the company's physical AI team laid out detailed technical specs for Cosmos 3 — a fully open-source world foundation model that unifies text, vision, audio, and action in a single Transformer architecture. Cosmos 3 replaces the fragmented patchwork of separate vision, language, and control models with one unified system.

Block open-sources Berd, a desktop app for juggling AI agents across models

Block just dropped Berd into the open — a desktop app that lets you work with AI agents from any provider in a single window, released under Apache 2.0. The project, built on Tauri 2 and React 19, wraps Block's own Goose agent backend and already has 216 GitHub stars within days of going live. The bet is straightforward: as teams start using multiple AI agents for different tasks, they need one interface instead of five browser tabs.

Qwen3.8-27B hits 1M downloads as small open models close the frontier gap

Alibaba's latest open-source release is turning heads: Qwen3.8-27B, a 27-billion-parameter model that runs on personal computers, has crossed one million downloads within days of launch and is outperforming models several times its size on independent benchmarks. The model scored 52 on the Artificial Analysis Intelligence Index — placing it above every medium-class open model (40B–150B parameters) and tying with DeepSeek V4 Flash, which ranks fifth among all large models.

DFlash 2 brings 20% faster parallel drafting to the inference stack

DFlash 2 brings 20% faster parallel drafting to the inference stack

Inference is eating AI's bill, and a new open-source release just made it cheaper to run. DFlash 2, a block-diffusion draft model from Inco AI, ships checkpoints for Qwen3.8-27B and Muse-Glimmer-30B — and claims over 20% more output per verification pass at roughly 1% added latency. The core idea is speculative decoding: a small draft model guesses a block of tokens, the large model verifies the whole block in one forward pass.

Open Source Radar — August 18: video, pentests & Mac inference

The coding-agent parade took a day off. Today's daily board is a 107k-star video factory still shipping, an AI pentester that validates its own findings, a Mac inference server built for real coding work, and a memory layer that survives switching vendors. MoneyPrinterTurbo (Python, ~107k stars) — Give it a topic or keyword and it writes the script, pulls footage, burns in subtitles and music, and hands you an HD short.

A mixed bag today: Mistral ships a small safety classifier, Y Combinator open-sources an enterprise agent harness, and embodied-AI news comes in two speeds — a nimble cleaning robot and a humanoid that drives a go-kart. Mistral's Shieldstral packs frontier-grade content moderation into a 3B model. The French lab released a small multimodal safety classifier that judges text, images, and mixed content against natural-language rules you define at inference time — so businesses can tune the…

Open Source Radar — August 17: agents go desktop-native

Today's board is light on new coding agents and heavy on the layers around them — making the desktop software agents can't yet reach runnable, making their diagrams look like design work instead of tool output, and making fine-tuning something you can do on a laptop. Three fresh projects worth your attention. CLI-Anything (Python, ~47.7k stars) — A project out of HKUDS that wants to make every piece of software agent-native: it wraps desktop tools — CAD packages, Blender, Obsidian…

Huawei's open-source WorkSwarm brings swarm agents to HarmonyOS PC

The multi-agent trend crossed a new threshold this week: openJiuwen, the open-source agent platform built by Huawei's 2012 Labs, Huawei Cloud and the terminal team, launched WorkSwarm — a swarm of office agents that collaborate as a team, not a single assistant — and it's the first of its kind on the HarmonyOS PC app store. Huawei-backed openJiuwen upgraded its JiuwenSwarm engine into WorkSwarm, a full office-agent suite that ships on the HarmonyOS PC app store with Windows and Mac support.
