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.
Muse Spark 1.2 Contributor is Meta Superintelligence Labs' cost-reduced access tier for its proprietary Muse Spark 1.2 reasoning model (a Stable LatentMoE design activating 16 of 896 experts per token via Kimi Delta Attention), offering a roughly 1M-token context window across text, image, video, audio, and PDF input. In exchange for pricing more than 10 times cheaper than the standard tier, prompts and outputs on this tier may be used by Meta to improve its products, making it best suited for experimentation and early-stage projects rather than data-sensitive production use.
