GPT-4 is OpenAI's landmark large multimodal model offering strong reasoning, coding, and instruction-following well beyond GPT-3.5. It is suited for complex tasks requiring deeper reasoning, though it has largely been superseded by faster, cheaper GPT-4o and GPT-4.1 models.
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.
