When to choose each
Claude Haiku 5.5
Best for
- High-volume classification, extraction and routing under the 100,000-token line
- Cost-sensitive fan-out steps where a frontier model is overkill
Watch out for
- Priced by prompt length, and it is a cliff rather than a taper: a request whose prompt passes 100,000 tokens is billed at $0.50 input and $2.50 output for the whole request, five times the short rate
- Cache reads and cache writes both count toward that 100,000-token measurement, so a large cached prefix can tip a request into the higher band on its own
- It is the only current Claude model whose 1M window is not priced uniformly; every other 4.6-and-later model bills a 900k request at the same rate as a 9k one
Gemini 3.1 Flash-Lite
Best for
- High-volume multimodal extraction and translation
Watch out for
- The published price for audio input differs from the listed text, image, and video input price
- Google's earliest published shutdown date is 2027-05-07; migrate to gemini-3.5-flash-lite.
