This is the discounted 'contributor' tier of Meta's Muse Spark 1.3 coding and agentic model, priced far below the standard endpoint (about $0.10/$0.20 per million input/output tokens versus $1.25/$4.25) in exchange for letting Meta use your prompts and completions for training. Capabilities match the standard model, so it is best reserved for non-sensitive workloads where that data-sharing tradeoff is acceptable.

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.
