Meta's coding-optimized open-weight model Muse Spark Open is now available on Amazon SageMaker JumpStart. The MoE model has 816B total parameters with 42B active per token, supports a 1M-token context window, takes text, image, document, audio, and audio-video input with text output, and is open-weight under the Muse Model License.
Meta has released Muse Spark Open, an open-weight multimodal mixture-of-experts model with roughly 816B total parameters and about 42B activated per token. It supports text, image, audio and video inputs, offers a context window of up to 1M tokens, and was trained for agentic coding.
Why it matters: The official blog details the model's scale and architecture plus a full deployment path from llama.cpp to TRL fine-tuning, letting readers evaluate the cost of putting it into production.
At the OCP Global Summit, NVIDIA announced it is contributing Vera Rubin rack and compute tray designs to the OCP through its MGX open architecture. The MGX 1.2 spec adds rack-level blind-mate liquid cooling, a 5000A liquid-cooled busbar, and support for rack deployments of up to 250kW.
Why it matters: The piece collects multiple open specifications such as MGX 1.2 and Open Data Center Specification v0.7, along with accompanying software, giving readers a view into the open foundations of AI factories.
Arista Networks (NYSE: ANET) announced an open Ethernet rack-scale portfolio on October 7, 2026, in collaboration with AMD, Arm, Broadcom, d-Matrix, Meta, Microsoft, Qualcomm and others, extending Ethernet into the scale-up domain based on its ESUN initiative.
Ai2 released Olmo-core 3, a redesigned open-source MoE training system that scales to trillion-parameter sizes. It switches from FSDP to a DDP-based approach, with a 47B-parameter MoE reaching a throughput of 52 on 8 NVIDIA B300 GPUs.
Meta today released Muse Glimmer, a 30B-parameter open-source multimodal model distilled from Muse under the Apache 2.0 license, aimed at privacy-focused local deployment and agentic uses like coding, document analysis, and personal assistance.
Why it matters: The article provides architecture details, agent benchmark comparisons, and day-0 usage across inference stacks, helping readers evaluate local multimodal deployment options.
At Advancing AI 2026 on July 23, AMD unveiled a full-stack AI and physical AI product portfolio, including its first rackscale solution, AMD Helios (72 Instinct MI455X GPUs plus 18 6th Gen EPYC "Venice" CPUs).
Why it matters: The official announcement consolidates Helios rack, MI400 series CPU/GPU spec figures, and major customer deployment plans, allowing readers to benchmark actual progress against competing solutions.
On May 19, Google announced an expansion of its content transparency and verification tools, covering Search, Gemini, Chrome, Pixel, and Cloud.
Why it matters: The original maps out how SynthID watermarking and C2PA Content Credentials verification are being extended across Search, Gemini, Chrome, and Pixel, along with rollout timing, to show where content provenance tools stand.
