GPT-3.5 Turbo Instruct is OpenAI's completion-style (non-chat) variant of GPT-3.5 Turbo, designed for legacy instruction-following completion APIs rather than multi-turn chat. It is suited for simple text completion and instruction tasks in legacy integrations.
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.
