Compare models
Put models side by side on price, context, capabilities, and benchmarks.
GPT-4.1 Nano is OpenAI's smallest and fastest GPT-4.1 variant, optimized for extremely low-latency, low-cost tasks such as classification, extraction, and simple chat. It sacrifices some capability for speed and price relative to Mini and full GPT-4.1.
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.
