Meta releases Muse Spark Open model with 816 billion parameters
The Decoder: Muse Spark Open is Meta's answer to Qwen, GLM, and Kimi in the open-weight race
Meta's Muse Spark Open is a new open-weight model with 816 billion parameters that processes text, images, video, and audio with up to one million tokens of context. It performs roughly on par with the most capable open-weight Chinese AI models on benchmarks and is optimized to run locally on Apple's M5 Ultra.

Part of a story that several outlets report: Meta releases Muse Spark Open AI model for coding
Get smart on it
Meta has released Muse Spark Open, an open-weight AI model designed for coding and agentic tasks with 816 billion parameters and support for text, image, video, and audio inputs. The model performs well ahead of competitors like Qwen, GLM, and Kimi on several benchmark tests, though it still falls short of Meta's own paid Muse Wonder Full models. The weights are freely available on Hugging Face, though commercial providers earning over $20 million annually need a separate agreement with Meta to offer it as an API service. This release represents Meta's entry into the competitive open-weight AI model race against other major players in the field.

Cloudflare Releases Clairic, a System One Extraction Model on Workers AI
Cloudflare has released a preview of Clairic, a new System One extraction model on Workers AI. The Cloudflare Clairic extraction model reads text or images and returns typed values, not generated text. It targets a job developers usually give to LLMs: pulling totals, dates and IDs into JSON. Clairic answers every requested field in 1 forward pass, with no reasoning and no output tokens. TL;DR Size: Parameter count not disclosed. 65,536-token context window, up to 4 images per request.
