Frequently asked questions
Yes, Claude Haiku 4.5 is cheaper for the typical workload above. At $1.00/1M input and $5.00/1M output tokens, it costs $1.5000 versus $2.2500 for Gemini 3.6 Flash — a 33% difference. Costs scale linearly with request volume, so larger workloads amplify this gap.
Claude Haiku 4.5 supports a 200K token context window. Gemini 3.6 Flash 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 3.6 Flash 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 3.6 Flash 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 3.6 Flash (Google): $1.5 input / $7.5 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 3.6 Flash costs $6.3000. Claude Haiku 4.5 is 33% 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 3.6 Flash has a 1M-token context window — approximately 750K words or ~3K pages. (Estimates assume ~0.75 words per token.)
