GPT-5.2-Codex is the coding-specialized variant of GPT-5.2, built for agentic software engineering across large codebases. It benefits from GPT-5.2's large context window for repository-scale refactors and long-horizon coding tasks.
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.
