Meta dives into AI coding race with Muse Spark 1.1 and aggressive pricing

Meta rolled out Muse Spark 1.1, its best-performing model for agentic and coding tasks, with a public developer API after a private preview and pricing designed to attract high usage: $20 in free credits, then $1.25 per million input tokens and $4.25 per million output tokens. The move aims to competing with OpenAI and Anthropic, with initial API access limited to Meta properties while scaling, and Meta says a Muse Spark variant will remain open source even as it develops a more powerful model codenamed Watermelon; Muse Spark’s development follows Muse Image and signals a broader shift from open-source Llama toward paid access to proprietary AI models.
