Meta Platforms Inc.Meta introduces new AI coding model Muse Spark 1.3, outperforming rivals in benchmarks.

Meta Platforms gained about 3% Thursday after introducing Muse Spark 1.3, a new artificial intelligence model focused on extended agentic tasks and software development. The model supports Muse Code, a coding agent that operates in terminal and continuous integration environments, planning tasks, modifying projects, and executing commands with approvals and an OS sandbox. In several coding benchmarks, including DeepSWE v1.1 and Terminal-Bench 2.1, Muse Spark 1.3 scored higher than Anthropic's Claude Opus 5 and OpenAI's GPT 5.6 Sol, though it did not lead in all agent-focused tests. The release is part of Meta's broader AI push, but competitive results suggest investors will watch how quickly these models translate into products and revenue.
