Muse Spark 1.3 is Meta's proprietary coding and agentic model, released September 2, 2026 with a 1M-token context window and text, image, and video input, served through Muse Code and the Meta Model API. It is Meta's largest coding and agentic improvement to date, running roughly 20% fewer tool calls and 25% fewer tokens per task than Muse Spark 1.2 while sustaining longer-horizon work, and defaults to its broadly available xhigh reasoning level.
Claude Haiku 4.5 is Anthropic's fast, affordable small model in the Claude 4 generation, balancing strong instruction-following and coding ability with low latency. It is designed for high-throughput agentic and chat applications where speed and cost efficiency are priorities.
