For high-volume, latency-sensitive work, Claude Haiku 4.5 and Gemini 3 Flash are the fast, cheap tiers to compare. Haiku 4.5 is the fastest Claude, with surprisingly strong near-frontier intelligence. It is ideal for classification, extraction, routing, real-time chat and the cheap inner steps of agent pipelines, where it occasionally produces the cleanest output of the whole Claude line.
Gemini 3 Flash delivers frontier-adjacent intelligence at roughly 4x lower cost than Gemini 3 Pro, with Gemini's multimodal strengths and wide availability across Google surfaces. Haiku edges short-task crispness and Claude-style reliability; Gemini 3 Flash edges multimodality and raw cost-efficiency. Both are excellent defaults for the bulk of everyday, high-throughput work.
