What happened

Meta has released Muse Code in beta, a terminal coding agent powered by Muse Spark 1.2, according to reporting cited by Techmeme. Jonathan Vanian of CNBC reported the coding-focused model is priced at $1.25 per million input tokens and $4.25 per million output tokens.

MarkTechPost reports Meta Superintelligence Labs says Muse Code plans changes, writes code, and validates results across large repositories using async background agents. Techmeme also cites Wall Street Journal reporting on a cheaper Muse Spark 1.2 contributor tier at $0.10 per million input and $0.20 per million output tokens in exchange for using user prompts for training.

Evidence

• Meta released Muse Code in beta as a terminal coding agent powered by Muse Spark 1.2 with stated API token pricing.

Why it matters

Developers now have a Meta-backed terminal agent with published per-token rates and an optional data-contributor tier for cost-sensitive workloads.

Limits and uncertainties

Muse Code is in beta; availability, limits, and production readiness are not fully specified in the packet.

Standard Muse Spark 1.2 pricing is attributed to CNBC via Techmeme, not a direct Meta pricing page in this packet.

Contributor tier terms beyond per-token rates and prompt use for training are not detailed here.

Practical implications

Teams can benchmark Muse Spark 1.2 against current coding-agent stacks using the cited $1.25 per million input and $4.25 per million output token rates.

High-volume, non-sensitive workloads may warrant evaluating the contributor tier only if accepting prompt use for training aligns with data policy.

What to watch

Whether Muse Code moves beyond beta and what access limits or regional availability Meta publishes.
