Meta shifts from open-weight AI, frontier moves to China

Meta, a key player in open-weight LLMs, has shifted its focus away from releasing open models, with its last public releases being Llama 4 Scout and Maverick in April 2025. The company's more recent frontier model, Muse Spark, was released as a private API, and significant layoffs suggest a strategic pivot. Despite Meta's move, the open-weight AI frontier has not collapsed but has instead relocated, primarily to Chinese labs, with Western holdouts also contributing. Current open-weight models now lag behind the best closed-frontier models by an average of about four months, a significant reduction from previous gaps, though the true gap may be slightly larger than reported.
