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.
GPT-5.4 Nano
Cheapest OpenAI option for high-throughput classification, tagging, and routing — ideal as a first-pass filter before a stronger model.
Limited reasoning depth means it should be treated as a triage layer, not a final answer source, for anything business-critical.
