It\u2019s small enough to run on a Mac or PC with a single consumer GPU, enabling use cases that range from local agents and function calling, to local coding, and LLM-as-a-judge evaluation. Muse\u00a0Glimmer delivers strong performance on key agentic use cases and benchmarks compared with leading models in its size category.<\/p>\n<p class=\"text-text-paragraph text-base leading-7 sm:text-lg sm:leading-8\">Foundation models have achieved remarkable capabilities across reasoning, code generation, and tool use \u2014 yet most deployments still depend on cloud infrastructure and network access. Running models locally enables you to use AI anywhere, anytime, with or without an internet connection. This is increasingly viable: the open source community has shown that smaller models, when trained effectively, can approach frontier-level performance on targeted tasks. Muse\u00a0Glimmer is optimized for these local use cases.<\/p>\n<p class=\"text-text-paragraph text-base leading-7 sm:text-lg sm:leading-8\">Keeping with our long tradition of sharing fundamental AI research, we&#8217;re releasing Muse\u00a0Glimmer open weights today on <a class=\"text-link underline underline-offset-4\" rel=\"noopener noreferrer\" target=\"_blank\" href=\"https:\/\/huggingface.co\/meta-models\/Muse-Glimmer-30B\">Hugging\u00a0Face<\/a>, along with <a class=\"text-link underline underline-offset-4\" rel=\"noopener noreferrer\" target=\"_blank\" href=\"https:\/\/dev.meta.ai\/docs\/muse-glimmer\">developer documentation<\/a> to help you start building and running your own agents. Muse\u00a0Glimmer is built to work with the tools developers already use. Optimized integrations on llama.cpp, MLX, and ExecuTorch will land in the coming days, so you can go from download to working agent in minutes.<\/p>\n<h2 class=\"font-display text-text-primary pt-8 text-3xl leading-tight font-medium\">How We Trained Muse\u00a0Glimmer<\/h2>\n<p class=\"text-text-paragraph text-base leading-7 sm:text-lg sm:leading-8\">An agent that manages your schedule, drafts your messages, organizes your files, and learns how you work needs deep access to personal context. It also needs several capabilities working in concert: long-horizon execution, precise tool calling, multimodal understanding, long-context memory, and instruction following.<\/p>\n<p class=\"text-text-paragraph text-base leading-7 sm:text-lg sm:leading-8\">We designed Muse\u00a0Glimmer to balance capability against the memory and compute constraints of local hardware. This required a compact architecture, a novel distillation recipe that transfers agentic reasoning from a much larger teacher model, and inference optimizations \u2014 including quantization \u2014 to meet latency expectations. We achieved this in the following phases:<\/p>\n<ul class=\"text-text-paragraph list-disc space-y-2 ps-6 leading-7\">\n<li><strong>Pre-Training.<\/strong> We trained Muse\u00a0Glimmer on Muse\u00a0Spark&#8217;s outputs using logit distillation, leveraging a similar data mix as the teacher.<\/li>\n<li><strong>Mid-Training.<\/strong> We trained the model on longer-context, more agent-heavy data with richer reasoning traces, alongside organic data.<\/li>\n<li><strong>Post-Training.<\/strong> We combined supervised fine-tuning with a mix of on-policy distillation and reinforcement learning across general, reasoning, coding, and agentic domains.<\/li>\n<\/ul>\n<p class=\"text-text-paragraph text-base leading-7 sm:text-lg sm:leading-8\">Muse\u00a0Glimmer was evaluated under the standards set out in <a class=\"text-link underline underline-offset-4\" rel=\"noopener noreferrer\" target=\"_blank\" href=\"https:\/\/ai.meta.com\/blog\/scaling-how-we-build-test-advanced-ai\/\">Meta&#8217;s Advanced AI Scaling Framework<\/a> and assessed for open-weight release across all relevant categories.<\/p>\n<h2 class=\"font-display text-text-primary pt-8 text-3xl leading-tight font-medium\">Built for Agents: What Muse\u00a0Glimmer Can Do<\/h2>\n<p class=\"text-text-paragraph text-base leading-7 sm:text-lg sm:leading-8\">Building effective agents requires key capabilities working together to achieve the user\u2019s goals. Muse\u00a0Glimmer is trained and evaluated across each of the following:<\/p>\n<ul class=\"text-text-paragraph list-disc space-y-2 ps-6 leading-7\">\n<li><strong>End-to-end Agentic Task Completion.<\/strong> Muse\u00a0Glimmer achieves strong success rates on full-task benchmarks including DeepSearch QA, MCP-Atlas, \ud835\uded5-Bench and SWE-Bench, which measure its ability to work within scaffolds, write and debug code, and resolve multi-turn requests from start to finish.<\/li>\n<li><strong>Reliable Tool Use.<\/strong> The model handles a wide range of function calls, invoking tools with precise schemas throughout extended workflows.<\/li>\n<li><strong>Multi-Step Reasoning.<\/strong> Muse\u00a0Glimmer chains reasoning over long horizons, sustaining coherent plans across complex, extended workflows.<\/li>\n<li><strong>Failure Recovery.<\/strong> When a tool call fails or returns an unexpected result, the model is trained to diagnose the error and retry rather than halt.<\/li>\n<li><strong>Multimodal Input and Reasoning.<\/strong> Through a dedicated perception encoder, the model accepts interleaved text and images. This enables agents to interpret screenshots, charts, and documents alongside conversation.<\/li>\n<li><strong>Scaffold Compatibility.<\/strong> Muse\u00a0Glimmer works across OpenClaw and other agentic orchestration patterns.<\/li>\n<li><strong>Controllable Effort.<\/strong> Muse\u00a0Glimmer supports different reasoning strengths to select the right balance between quality and speed.<\/li>\n<li><strong>Multilingual.<\/strong> Muse\u00a0Glimmer is trained on data from more than 100 languages.<\/li>\n<\/ul>\n<figure class=\"article-media-module__3u0F1q__figure article-media-module__3u0F1q__full\" data-media-placement=\"full\"\/>\n<h2 class=\"font-display text-text-primary pt-8 text-3xl leading-tight font-medium\">Performance<\/h2>\n<p class=\"text-text-paragraph text-base leading-7 sm:text-lg sm:leading-8\">We evaluated Muse\u00a0Glimmer across a broad range of benchmarks to assess the diverse capabilities required for effective autonomous agent behavior. Compared with Gemma4-31B and Qwen3.6-27B, Muse\u00a0Glimmer performs strongly for its size class on several widely used LLM benchmarks.<\/p>\n<figure class=\"article-media-module__3u0F1q__figure article-media-module__3u0F1q__wide\" data-media-placement=\"wide\">\n<div class=\"article-media-module__3u0F1q__shell\"><picture class=\"site-image-module__lM2DSa__picture\"><source data-responsive-media=\"true\" sizes=\"(min-width: 950px) 1804px, calc(200vw - 96px)\" srcset=\"https:\/\/lookaside.fbsbx.com\/elementpath\/media\/?media_id=1763817931416938&amp;version=1786388559&amp;transcode_extension=webp&amp;resize_width=480&amp;resize_height=4800 480w, https:\/\/lookaside.fbsbx.com\/elementpath\/media\/?media_id=1763817931416938&amp;version=1786388559&amp;transcode_extension=webp&amp;resize_width=960&amp;resize_height=9600 960w, https:\/\/lookaside.fbsbx.com\/elementpath\/media\/?media_id=1763817931416938&amp;version=1786388559&amp;transcode_extension=webp&amp;resize_width=1440&amp;resize_height=14400 1440w, https:\/\/lookaside.fbsbx.com\/elementpath\/media\/?media_id=1763817931416938&amp;version=1786388559&amp;transcode_extension=webp&amp;resize_width=1920&amp;resize_height=19200 1920w, https:\/\/lookaside.fbsbx.com\/elementpath\/media\/?media_id=1763817931416938&amp;version=1786388559 2160w\"\/><\/picture><\/div>\n<\/figure>\n<p class=\"text-text-paragraph text-base leading-7 sm:text-lg sm:leading-8\">For more detail about our evaluations, see <a class=\"text-link underline underline-offset-4\" rel=\"noopener noreferrer\" target=\"_blank\" href=\"https:\/\/research.meta.ai\/static\/muse-glimmer-methodology\">our report<\/a>.<\/p>\n<h2 class=\"font-display text-text-primary pt-8 text-3xl leading-tight font-medium\">Optimized for Local Deployments<\/h2>\n<p class=\"text-text-paragraph text-base leading-7 sm:text-lg sm:leading-8\">A local agent is truly useful if it&#8217;s fast enough to feel responsive. An agent that takes minutes to reply or plan its next step breaks the flow of real work. We applied two optimizations to make Muse\u00a0Glimmer run at practical speeds on consumer hardware without sacrificing quality.<\/p>\n<h3 class=\"font-display text-text-primary pt-5 text-xl leading-tight font-medium\">Fitting the Model on Your Device.<\/h3>\n<p class=\"text-text-paragraph text-base leading-7 sm:text-lg sm:leading-8\">At full precision, a 30-billion parameter model would require over 55 GB of memory \u2014 far more than any consumer GPU offers. We use quantization techniques to compress the model&#8217;s weights to approximately 4-bit precision, shrinking the language model to under 20 GB. This leaves enough headroom for the model&#8217;s working memory (its &#8220;KV cache&#8221;), the perception encoder for image understanding, and the speculative decoding drafter to run simultaneously within a 24 GB or 32 GB envelope. We validated that this compression introduces minimal to no degradation on agentic tasks.<\/p>\n<figure class=\"article-media-module__3u0F1q__figure article-media-module__3u0F1q__wide\" data-media-placement=\"wide\">\n<div class=\"article-media-module__3u0F1q__shell\"><picture class=\"site-image-module__lM2DSa__picture\"><source data-responsive-media=\"true\" sizes=\"(min-width: 950px) 1804px, calc(200vw - 96px)\" srcset=\"https:\/\/lookaside.fbsbx.com\/elementpath\/media\/?media_id=1479406130664613&amp;version=1786319248&amp;transcode_extension=webp&amp;resize_width=480&amp;resize_height=4800 480w, https:\/\/lookaside.fbsbx.com\/elementpath\/media\/?media_id=1479406130664613&amp;version=1786319248&amp;transcode_extension=webp&amp;resize_width=960&amp;resize_height=9600 960w, https:\/\/lookaside.fbsbx.com\/elementpath\/media\/?media_id=1479406130664613&amp;version=1786319248&amp;transcode_extension=webp&amp;resize_width=1440&amp;resize_height=14400 1440w, https:\/\/lookaside.fbsbx.com\/elementpath\/media\/?media_id=1479406130664613&amp;version=1786319248&amp;transcode_extension=webp&amp;resize_width=1920&amp;resize_height=19200 1920w, https:\/\/lookaside.fbsbx.com\/elementpath\/media\/?media_id=1479406130664613&amp;version=1786319248 2160w\"\/><img loading=\"lazy\" data-media-backup-available=\"true\" data-media-backup-key=\"muse-glimmer\/quantization-table\/v1\" data-media-failure-sequence-id=\"_R_anpbsnpff5tklb_\" data-media-fallback-kind=\"primary\" data-media-fallback-remaining=\"true\" alt=\"Table comparing full precision, K-Quant-Dynamic, and K-Quant-17GB by accuracy degradation and target hardware memory.\" data-media-placeholder=\"true\" data-observability-media-key=\"muse-glimmer\/quantization-table\/v1\" data-responsive-media=\"true\" loading=\"lazy\" width=\"2160\" height=\"674\" decoding=\"async\" data-nimg=\"1\" class=\"site-image-module__lM2DSa__image article-media-module__3u0F1q__media article-media-module__3u0F1q__contain\" style=\"color:transparent\" src=\"https:\/\/lookaside.fbsbx.com\/elementpath\/media\/?media_id=1479406130664613&amp;version=1786319248\"\/><\/picture><\/div>\n<\/figure>\n<h3 class=\"font-display text-text-primary pt-5 text-xl leading-tight font-medium\">Faster Generation Through Speculative Decoding.<\/h3>\n<p class=\"text-text-paragraph text-base leading-7 sm:text-lg sm:leading-8\">Language models normally generate text one token at a time, which can feel slow during long reasoning chains or multi-step tool calls. Muse\u00a0Glimmer ships with a lightweight &#8220;drafter&#8221; model based on <a class=\"text-link underline underline-offset-4\" rel=\"noopener noreferrer\" target=\"_blank\" href=\"https:\/\/arxiv.org\/abs\/2602.06036\">DFlash<\/a> \u2014 a small companion network that proposes entire blocks of tokens at once. The main model then verifies these proposals in parallel, accepting correct tokens and correcting wrong ones. This technique lets Muse\u00a0Glimmer generate text significantly faster than standard token-by-token generation while producing identical output quality. We provide quantized drafter versions to incur a smaller memory overhead in the release.<\/p>\n<figure class=\"article-media-module__3u0F1q__figure article-media-module__3u0F1q__full\" data-media-placement=\"full\"\/>\n<h3 class=\"font-display text-text-primary pt-5 text-xl leading-tight font-medium\">The Result:<\/h3>\n<p class=\"text-text-paragraph text-base leading-7 sm:text-lg sm:leading-8\">We measure the speed of our K-Quant-17GB model alongside the quantized DFlash drafter on MacBook\u00a0M4-Max, M5-Max and on a RTX-5090. The model is fast enough for fluid conversation and real-time agent interaction, all running entirely on your device.<\/p>\n<figure class=\"article-media-module__3u0F1q__figure article-media-module__3u0F1q__wide\" data-media-placement=\"wide\">\n<div class=\"article-media-module__3u0F1q__shell\"><picture class=\"site-image-module__lM2DSa__picture\"><source data-responsive-media=\"true\" sizes=\"(min-width: 950px) 1353px, calc(150vw - 72px)\" srcset=\"https:\/\/lookaside.fbsbx.com\/elementpath\/media\/?media_id=1786825739136571&amp;version=1786319248&amp;transcode_extension=webp&amp;resize_width=480&amp;resize_height=4800 480w, https:\/\/lookaside.fbsbx.com\/elementpath\/media\/?media_id=1786825739136571&amp;version=1786319248&amp;transcode_extension=webp&amp;resize_width=960&amp;resize_height=9600 960w, https:\/\/lookaside.fbsbx.com\/elementpath\/media\/?media_id=1786825739136571&amp;version=1786319248 1080w\"\/><img loading=\"lazy\" data-media-backup-available=\"true\" data-media-backup-key=\"muse-glimmer\/inference-time-chart\/v1\" data-media-failure-sequence-id=\"_R_bfpbsnpff5tklb_\" data-media-fallback-kind=\"primary\" data-media-fallback-remaining=\"true\" alt=\"Bar chart showing DFlash speculative decoding increasing Muse\u00a0Glimmer decode speed by 3.1 times on RTX 5090, 1.8 times on M5 Max, and 1.5 times on M4 Max.\" data-media-placeholder=\"true\" data-observability-media-key=\"muse-glimmer\/inference-time-chart\/v1\" data-responsive-media=\"true\" loading=\"lazy\" width=\"1080\" height=\"1080\" decoding=\"async\" data-nimg=\"1\" class=\"site-image-module__lM2DSa__image article-media-module__3u0F1q__media article-media-module__3u0F1q__contain\" style=\"color:transparent\" src=\"https:\/\/lookaside.fbsbx.com\/elementpath\/media\/?media_id=1786825739136571&amp;version=1786319248\"\/><\/picture><\/div>\n<\/figure>\n<h2 class=\"font-display text-text-primary pt-8 text-3xl leading-tight font-medium\">Get Started With Muse\u00a0Glimmer Today<\/h2>\n<p class=\"text-text-paragraph text-base leading-7 sm:text-lg sm:leading-8\">Muse\u00a0Glimmer is available now, and you can download the weights on <a class=\"text-link underline underline-offset-4\" rel=\"noopener noreferrer\" target=\"_blank\" href=\"https:\/\/huggingface.co\/meta-models\/Muse-Glimmer-30B\">Hugging\u00a0Face<\/a>.
