    Hao AI Lab releases the ORA open-source robot agent framework, powered by DeepSeek-V4.1-Flash

    Hao AI Lab releases the ORA (Open Robot-Use Agents) open-source framework, powered by DeepSeek-V4.1-Flash, which operates robots zero-shot from visual input without VLA and can compete with frontier model agents. ORA achieves 69.2% on RoboTwin and 81.4% on LIBERO-Pro; by comparison, RPent achieves 62.4%/58.4% on RoboTwin (GPT-5.5/Opus-4.7) and 82.4% on LIBERO-Pro (Opus-4.7). It works similarly to a coding agent, completing the loop through prompts, perception and action tools, and context management; the same framework can run ARX X5, ALOHA, and Franka, with a model cost of about $0.30–0.35 per solved case. In preliminary real-robot tests, DeepSeek-V4.1-Flash used a low-cost robotic arm, a fixed RGB-D camera, and a wrist camera to pull open a drawer handle and put candy into a box.

    Meta open-sources 816B-parameter model Muse Spark Open on Hugging Face

    Meta has released the model weights of Muse Spark Open on Hugging Face, an 816B-parameter model aimed at coding and agent tasks. The open-source version shares the same base model as Muse Spark 1.3, with additional safety post-training to reduce the risk of misuse when used standalone without system guardrails, reversing Meta's strategy of its first proprietary closed frontier model in April this year. The model has 62 layers, each containing 256 expert networks, with each token routed to 8 of them, so deployment requires the memory of an 816B-parameter model but runs at the speed of a 42B model. A 3-bit quantized version tested on a 512GB M3 Ultra occupies about 344 GB, with generation speed of about 21 tok/s under short prompts.

    Meta open-sources 816B-parameter multimodal model Muse Spark Open

    On October 15, Meta released the weights of Muse Spark Open, a natively multimodal open-source model with 816B total parameters, 42B activated parameters, and a 1M token context window, targeting coding and long-horizon agent tasks. The model uses a MoE Transformer plus Perception Encoder architecture, can be invoked through API platforms such as Baseten, Fireworks AI, and Groq, with weights downloadable from Hugging Face, Amazon SageMaker AI, Google Cloud Model Garden, and elsewhere; running the NVFP4 version locally requires at least 700GB of VRAM. Meta claims it is the first model of its class that can run on desktop, carried by two Mac Studios equipped with M5 Ultra paired with the MLX framework; the model card shows its Artificial Analysis Intelligence Index at 39, lower than GLM 5.3's 45 and Kimi K3's 44 in the table.

    Meta releases 816B open-source model Muse Spark Open

    Meta releases Muse Spark Open, an open-weight model with 816B parameters and 42B activated parameters, using a 1 million token context window, callable via APIs such as Baseten, Fireworks AI, Groq, and OpenRouter, with weights downloadable from Hugging Face, Amazon SageMaker AI, Google Cloud Model Garden, and others. Meta says it targets coding and agent tasks and leads Kimi K3, GLM 5.3, and Qwen3.8 on agent and tool-calling benchmarks such as JobBench and MCP-Atlas, but trails on coding benchmarks such as Terminal-Bench 2.1 and DeepSWE 1.1. The model uses the Muse Model License; companies with annual revenue over $20 million must first notify Meta and sign a separate agreement to offer model services, and users must prominently label Built with Muse Spark Open in product interfaces.

    Meta releases Muse Spark Open, partnering with Apple to run on Mac Studio

    Meta releases Muse Spark Open, calling it the most capable US open-weight model to date, with 816B total parameters, 42B activated parameters, a 1 million token context window, and aimed at coding and agent tasks. The model was adapted for Mac Studio in partnership with Apple and can run on two 512GB M5 Ultra Mac Studios via the MLX framework; the 512GB Mac Studio is not yet on sale and is expected to launch later this month. Model weights can be downloaded from Hugging Face, Amazon SageMaker AI, Google Cloud Model Garden, and Microsoft Foundry Models, and can also be used via the APIs of Baseten, Fireworks AI, Groq, Modal, Nebius, OpenRouter, and Together AI; downloads are free under a license permitting limited commercial use.
