Facebook's parent company on Thursday updated its Muse Spark large language model to version 1.1, promising improvements in coding and handling longer tasks, and made it available to developers via an API. Meta charges $1.25 per million input tokens and $4.25 per million output tokens. Alexandr Wang, who was brought in to reboot Meta's AI effort, told Axios that improving performance in coding and agentic tasks was a key focus. Meta is also using the model to power the thinking mode in the Meta AI app and website. The company is promising a significantly more powerful version of Spark later this year that uses substantially more computing power. Earlier this week, Meta debuted Muse Image, a picture-generating model added to Meta AI and Instagram. A model code-named Watermelon, using vastly more compute, is still in training and should be released later this year. Wang said he is working toward a more agentic Meta AI that could handle tasks like planning a party or a vacation, noting Meta's strength is its billions of users and how much the company knows about them.
