Frequently asked questions
No, Llama 4 Scout is cheaper for the typical workload above. At $0.100/1M input and $0.300/1M output tokens, it costs $0.1100 versus $2.5500 for Gemini 3.5 Flash — a 96% difference.
Gemini 3.5 Flash supports a 1M token context window. Llama 4 Scout 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.
Gemini 3.5 Flash supports context caching (90% off repeated tokens). It offers a 50% Batch API discount. Llama 4 Scout does not support context caching. It does not offer a batch API discount.
No, they use different tokenizers. Gemini 3.5 Flash uses the Gemini tokenizer, while Llama 4 Scout uses Heuristic (~chars/4). 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.
Gemini 3.5 Flash (Google): $1.5 input / $9 output per 1M tokens. Llama 4 Scout (Meta): $0.1 input / $0.3 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 — Gemini 3.5 Flash costs $7.5000 per 1M total tokens and Llama 4 Scout costs $0.2600. Llama 4 Scout is 97% cheaper for this pattern. For your exact ratio, paste a real prompt into the calculator above.
