Frequently asked questions
No, Gemini 3.5 Flash-Lite is cheaper for the typical workload above. At $0.300/1M input and $2.50/1M output tokens, it costs $0.6500 versus $1.5000 for Claude Haiku 4.5 — a 57% difference.
Claude Haiku 4.5 supports a 200K token context window. Gemini 3.5 Flash-Lite supports a 1M token context window. A larger context window lets you include more text — documents, conversation history, or code — in a single API call.
Claude Haiku 4.5 supports context caching (90% off repeated tokens). It offers a 50% Batch API discount. Gemini 3.5 Flash-Lite supports context caching (90% off repeated tokens). It offers a 50% Batch API discount.
No, they use different tokenizers. Claude Haiku 4.5 uses the Anthropic tokenizer, while Gemini 3.5 Flash-Lite uses Gemini tokenizer. Different tokenizers split text differently, so the same prompt will produce different token counts on each model — the effective cost difference may be larger or smaller than the per-token price difference alone suggests.
Claude Haiku 4.5 (Anthropic): $1 input / $5 output per 1M tokens. Gemini 3.5 Flash-Lite (Google): $0.3 input / $2.5 output per 1M tokens. Rates shown before caching or batch discounts.
For an 80% output / 20% input workload — typical for code generation or long-form writing — Claude Haiku 4.5 costs $4.2000 per 1M total tokens and Gemini 3.5 Flash-Lite costs $2.0600. Gemini 3.5 Flash-Lite is 51% cheaper for this pattern. For your exact ratio, paste a real prompt into the calculator above.
Claude Haiku 4.5 has a 200K-token context window — approximately 150K words or ~600 pages of standard text. Gemini 3.5 Flash-Lite has a 1M-token context window — approximately 750K words or ~3K pages. (Estimates assume ~0.75 words per token.)
