Claude 3.5 Haiku (Oct 2024)
Claude 3.5 Haiku (October 2024) is a pinned, dated release of Anthropic's fastest model in the Claude 3.5 family. The dated identifier ensures that applications depending on consistent behavior are not affected by future model updates, making it the right choice for production systems requiring reproducibility and stable evaluation baselines.
As the smallest Claude 3.5 model, Haiku delivers rapid responses at lower cost while still benefiting from Anthropic's Constitutional AI training. It handles high-throughput tasks — summarization, classification, lightweight coding assistance, and conversational agents — where latency and cost-per-token are the primary constraints.
