Mark Zuckerberg criticizes "closed" AI model makers, says AI labs are espousing a "discourse ... so filled with doom", and defends distillation as a principle (Jamie John/Financial Times)
↗
Zuckerberg publicly attacked closed AI model makers and their doom-laden safety discourse while defending distillation, coinciding with Meta's release of the open-weight Muse Glimmer model and a commitment to open-weight Muse Spark 1.2.
The rhetoric reframes openness as the responsible default and positions closed-model companies as anti-competitive fear-mongers, which could influence regulatory debates around model access. For engineers, the practical upshot is a new 30B Apache 2.0-licensed agentic model that runs locally on consumer GPUs, with a more powerful open-weight model promised soon.

Zuckerberg framed closed AI labs as pushing excessive doom discourse and positioned open model releases as the responsible alternative.
Meta released Muse Glimmer, a 30B open-weight agentic model under Apache 2.0 that runs on 24GB VRAM and supports multi-step tool use and vision.
Meta committed to releasing open weights for its more advanced Muse Spark 1.2 model in the coming weeks.
