Relace Apply 3 is a specialized code-patching model that merges AI-suggested edits directly into existing source files at very high speed (thousands of tokens per second). It is designed to be paired with a larger generation model as a fast, cheap 'instant apply' layer, reducing latency and token cost in AI coding tools.
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.
