According to @AIatMeta, Meta FAIR released Code World Model (CWM), a 32B-parameter research model to study how world models can transform code generation and reasoning about code, and it is shared under a research license (source: AI at Meta on X, Sep 24, 2025). According to @AIatMeta, the open weights are available on Hugging Face at facebook/cwm, the project code is on GitHub at facebookresearch/cwm, and a technical report is linked via ai.meta.com (source: AI at Meta on X; Hugging Face facebook/cwm; GitHub facebookresearch/cwm). For traders, near-term tracking signals include Hugging Face download counts and GitHub stars and issues on the referenced repositories to gauge developer traction following this open-weight launch, as no crypto or token integration was mentioned in the announcement (source: Hugging Face facebook/cwm; GitHub facebookresearch/cwm; AI at Meta on X).

According to Vitalik Buterin, the cost associated with 405 billion parameters may be slightly above the current cost threshold but remains under the 10**26 FLOP threshold. He notes that advocates for open weights are pushing for transparency in near-frontier models, even as the development of these models becomes increasingly well-funded.

According to VitalikButerin, the cost associated with models at the 405 billion parameter level may be slightly above the cost threshold but still falls under the 10**26 flop threshold. He notes that advocates for open weights are pushing for near-frontier models to remain open even as the frontier becomes more financially robust.

According to Vitalik Buterin, there is uncertainty regarding the impact of a new bill on open weights in AI development. Buterin notes that earlier versions of the bill included a full shutdown requirement incompatible with open weights, but this has since been removed. He seeks evidence on whether the current bill will still target open weights, despite some AI safety advocates expressing support for the legislation.
