Meta returns to open source with Muse Glimmer, an Apache 2.0 licensed 30B parameter AI model optimized for agents — available now
Meta has made a notable pivot back to open source with the release of Muse Glimmer, a 30-billion-parameter open-weight AI model. This model is specifically designed to enable autonomous AI agents to run directly on consumer-grade hardware, shifting agentic workloads from cloud infrastructure to high-end Macs and PCs. The most significant aspect of this release is its licensing: Muse Glimmer is distributed under the permissive Apache 2.0 open-source license, a stark contrast to Meta's previous proprietary Muse Spark model and the more restrictive community license used for the Llama family.
This move represents Meta's first fully open release since Muse Spark launched in April. The Apache 2.0 license allows for unrestricted commercial use, modification, and redistribution, addressing criticisms leveled against Llama's license, which included a 700-million-monthly-user cutoff. The weights for Muse Glimmer are immediately available on Hugging Face, with broader support rolling out through platforms like Ollama, LM Studio, and Together AI. Meta CEO Mark Zuckerberg also teased the future open-weight release of Muse Spark 1.2, a frontier model previously behind Muse Code, signaling a broader commitment to open source within the Muse family.
Meta's Muse Glimmer marks a significant return to fully open-source AI, empowering local agentic workloads with a permissive Apache 2.0 license.
Muse Glimmer: 30B-parameter model optimized for always ...
The tech community, particularly on platforms like Hacker News, is reacting positively to Meta's latest release, Muse Glimmer. The news, titled "Meta Muse Glimmer – open weights 30B local coding model," quickly garnered attention, with users expressing enthusiasm for the availability of new open-weight models from Meta. One comment from user tosh encapsulated the sentiment: "good to see new open weights releases from meta."
This reception underscores the demand within the developer community for accessible and open-source AI models, especially those capable of running locally. The 30B-parameter size of Muse Glimmer suggests a powerful tool for various applications, including local coding. The quick spread of the news and immediate positive feedback on platforms like Hacker News further solidifies the impact of Meta's shift back to a more open model strategy.
The developer community on Hacker News has welcomed Meta's Muse Glimmer as a valuable open-weight, local coding AI model.
Platform Engineering ROI: What it costs to build your own platform - The New Stack
Platform Engineering continues to be a critical topic for software engineering leaders, and understanding the return on investment (ROI) for building an in-house platform is paramount. The article from The New Stack delves into the real costs and complexities associated with developing and maintaining a proprietary platform. It implies that while the benefits of a tailored platform can be significant, the resources required in terms of talent, time, and ongoing maintenance should not be underestimated.
The content highlights the importance of making informed decisions when considering a DIY platform versus leveraging existing solutions or vendors. Although specific cost figures are not provided, the emphasis on the need for thorough evaluation and understanding the commitment involved suggests that such endeavors are resource-intensive. For organizations, this means assessing their internal capabilities, the scale of their operations, and their long-term strategic goals to determine if the investment in building a platform aligns with their financial and operational objectives.
Building an in-house Platform Engineering solution demands a thorough cost-benefit analysis, considering the substantial investment in resources and expertise required.
WeatherNext: AI model achieves breakthrough in forecasting cyclones
Google DeepMind and Google Research, in collaboration with expert forecasters from institutions like the National Hurricane Center (NHC) and the UK Met Office, have developed WeatherNext, an AI model that marks a significant breakthrough in cyclone forecasting. This model has achieved state-of-the-art accuracy in predicting a cyclone's track, intensity, and wind structure, providing an average of an extra day's worth of predictive accuracy. This improvement is equivalent to approximately a decade of meteorological progress.
WeatherNext's real-world impact was evident during the 2025 hurricane season, where it assisted the NHC in making a historic forecast for Hurricane Melissa, accurately predicting its rapid intensification and landfall in Jamaica. This advanced warning allowed ground teams critical time to prepare. Given the broad impact of weather phenomena—tropical cyclones alone have been responsible for over 700,000 deaths and $1.4 trillion in economic losses globally over the past 50 years—Google DeepMind has open-sourced both WeatherNext 2 and WeatherNext Cyclones models to make this vital technology broadly accessible.
Google DeepMind's WeatherNext AI model provides an extra day of accurate cyclone forecasting, a breakthrough now open-sourced to aid global preparedness.
Google’s Top AI Brains Are Leaving to Launch Discovery Loop | WIRED
A significant shake-up in the AI world sees four of Google's most prominent AI scientists, including the legendary engineer Jeff Dean, departing the company to found a new startup called Discovery Loop. Dean, co-founder of Google Brain, chief scientist of Google DeepMind and Google Research, and technical co-lead on the flagship AI model Gemini, is joined by Sanjay Ghemawat, Oriol Vinyals, and Quoc Le.
Discovery Loop aims to leverage AI to achieve breakthroughs across various domains, from drug discovery to chip design, by automating the scientific method. Dean previously hinted at this interest during a Y Combinator Startup School event, describing an automated loop of proposing, implementing, evaluating, and getting results from experiments. This departure, despite Google taking a stake in the new venture, represents a considerable loss of top-tier talent for the search giant as it navigates the intense competition in AI model development, akin to founding members leaving a hugely successful band.
