Put models side by side on price, context, capabilities, and benchmarks.
o4-mini-high is OpenAI's o4-mini reasoning model at a higher reasoning-effort setting for improved accuracy on math, coding, and visual reasoning tasks. This is the batch variant for cheaper asynchronous processing.
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.
