Claude Haiku 4.5
Very low latency for high-volume, simple tasks — classification, short summaries, and lightweight chat where response time matters more than depth.
Noticeably weaker on multi-step reasoning and long-context synthesis; pairing with a larger model for escalation is common.
Gemini 3.1 Pro
Native audio, video, and document understanding with a ~1M token context window — strong fit for multi-modal RAG and large-document analysis.
Output token cost is steep relative to input, and the largest context windows can be slow to fill — chunk large documents where possible.
