SmolDataEnvs is an open-source set of more than 5,000 verifiable reinforcement-learning environment tasks for hill-climbing small models in code and data science. The release includes environments, evaluations, and training.
Token Meter is a free, open-source menu bar tool from Splunk that shows coding agent costs as a run is underway.
inclusionAI has open-sourced the Ming-Image-0.1-Design family under the MIT License: two complementary 6B models, Design and Layer, for visual-design workflows. ModelScope says Design ranks first among open-weight models on the Artificial Analysis UI/UX Design leaderboard, and that Layer leads all 12 evaluated Crello settings while running 4.3× faster than the evaluated 20B open-weight baseline.
Arena.ai places Qwen-Image-2.1 first among open-source models in both arenas. On Image Edit, it scores 1,367 points, ranks 16th overall, and trails GPT-Image-1.5-high-fidelity by three points.
On September 22, 2026, Ahmad Awais said he was launching Jev on Command Code for free, limited to headless mode or the Provider API. He also open-sourced the mod cmd-mod-jev-nudge.
Jev can be used only in headless mode or through the Provider API. Ahmad Awais also open-sourced the mod cmd-mod-jev-nudge and says the free access is for keeping an agent running while more work remains.
StepFun says onPanda, its internal tool for LLM data annotation and model inspection, is now open source. It reports a 52% lower median annotation time than manual post-editing and on-policy fidelity of ΔPPL under 1% versus the model’s resampling baseline.
Contributors from IBM, Meta, and Hugging Face present hardware-agnostic layers intended to balance frontier performance with portability for users running diverse models on diverse hardware.
StepFun has released the Step Code v0.1.0 command-line tool as open source under the MIT License, including one-command static site publishing with StepPage. StepFun reports 80.9% on Terminal-Bench 2.1 and 73.3% on Multi-Frame, its 150-task long-horizon benchmark.
Step Code v0.1.0 is an MIT-licensed CLI agent that reads and edits code, runs tests, and ships from one command line. StepFun reports 80.9% on Terminal-Bench 2.1 and 73.3% on Multi-Frame, its 150-task benchmark, and includes one-command publishing with StepPage.
The desk device shows idle, working, needs-a-decision, and done. Wahlin used Copilot CLI to create several animations and a web-based character studio, and published the project as esp32-agent-companion.
Clement Delangue (@ClementDelangue) said startup @eidon_ai open-sourced 1,274 hours of egocentric robotics data—13,451 recordings of humans doing everyday tasks—as a gift to the robotics community.
VIDEO REBIRTH says it open-sourced HyperFlow, that the ComfyUI community independently built support within two days, and that the community build has more downloads than its own.
Ghita told Jev users that zerank-2 is a 4B open-source reranker that also returns a confidence score, so a threshold can be set to use it as a classifier. The post said it can be self-hosted with Baseten or Fireworks AI and linked a Hugging Face model page.
