#2 𝕏 AI at Meta shared new evaluations and demos of Muse Spark 1.2, highlighting multimodal capabilities spanning visual-to-code generation, perception-to-physical action, and audio-visual understanding for video-heavy enterprise workflows. One demo shows the model parsing multimodal observations and calling tools to guide a robot through an unstructured environment to find a rubber duck. Also covered by: @AI at Meta , @Alexandr Wang

“Meta released Muse Glimmer, a 30 billion-parameter dense agentic model distilled from Muse Spark and licensed under Apache 2.0, with 4-bit quantization and DFlash speculative decoding for consumer-GPU use.”

#5 ▶️ Meta's new model wants "deep access" to your personal life... Fireship Meta released Muse Glimmer, a 30 billion-parameter dense agentic model distilled from Muse Spark and licensed under Apache 2.0, with 4-bit quantization and DFlash speculative decoding for consumer-GPU use. Muse Glimmer uses logit distillation from Meta's closed Muse Spark model; the transcript states it outperforms Gemma 4, performs comparably with Qwen 3.6, and has a 28% prompt-injection attack success rate versus 40% for Qwen. At full precision, Muse Glimmer requires more than 55 GB of memory; compressing its weights to approximately 4 bits reduces the model to just under 20 GB. A small draft model named DFlash generates token blocks for speculative decoding, after which Muse Glimmer verifies them in one pass; Meta reports a 3x speed increase on an NVIDIA 5090.

#4 𝕏 Sebastian Raschka recaps Meta’s release the previous day of Meta Muse Glimmer, an open-weight, dense 30B multimodal reasoning model with a 131k context window. Its 32 query heads and 2 KV heads deliver a 52 KiB BF16 KV cache per token, making it memory-efficient and well suited to agentic workflows, though benchmarks conflict on whether it outperforms Qwen3.6.
