Meta’s Muse Spark ranks second on OpenCode Go usage leaderboard

Meta’s Muse Spark model has reached the number two position on OpenCode Go’s weekly usage leaderboard. Developed by Meta Superintelligence Labs, the model is specifically designed for agentic coding and supports complex reasoning, multimodal tasks, and visual coding.

According to recent statistics, the Muse Spark 1.3 Contributor model recorded significant activity, with one report citing 36 trillion displayed tokens and another noting up to 79 trillion developer tokens across 120 million sessions. The model features a 1 million token context window, allowing it to process large codebases.

Meta offers a Contributor tier at heavily discounted rates—$0.10 per 1 million input tokens and $0.20 per 1 million output tokens—in exchange for permission to use prompts and completions to train future Meta models. Standard API pricing is significantly higher at $1.25 per million input tokens and $4.25 per million output tokens. Meta models collectively accounted for 23.7% of the displayed market share on the platform.
