Strengths
What Claude Haiku 4.5 brings to your workflows
- High-volume drafting processes large numbers of short responses quickly — ideal for support ticket replies, live chat messages, and batch content generation jobs.
- Vision input lets support agents or automated pipelines attach product screenshots and UI mockups alongside text when diagnosing customer issues or writing how-to responses.
- Tool use enables chatbot agents that query knowledge bases, ticketing systems, and internal APIs inline without switching context or breaking the conversation loop.
- A 200K-token context window holds long conversation histories and policy documents so the model stays oriented and consistent across extended multi-turn support sessions.
