GPT-5.5 is OpenAI's April 2026 flagship model, described as its most intuitive yet at understanding intent and carrying more of a task itself. It excels at writing and debugging code, research, data analysis, and multi-step agentic tool use, with reduced hallucination in sensitive domains like law, medicine, and finance.
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.
