DeepSeek R1 is DeepSeek's dedicated reasoning model, trained with reinforcement learning to produce explicit chain-of-thought before answering. It is designed for complex math, coding, and logic problems, and was notable for matching top closed reasoning models at a fraction of the cost.
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.
