Frequently Asked Questions

How much cheaper is Gemini 2.0 Flash than GPT-4o?

Gemini 2.0 Flash is dramatically cheaper — 25x less per request than GPT-4o. Gemini 2.0 Flash is cheaper on both input ($0.1/M vs $2.5/M) and output ($0.4/M vs $10.0/M). At a fraction of the cost, Gemini 2.0 Flash saves significantly in production workloads. This comparison assumes a typical request of 5,000 input and 1,000 output tokens (5:1 ratio). Actual ratios vary by workload — chat and completion tasks typically run 2:1, code review around 3:1, document analysis and summarization 10:1 to 50:1, and embedding workloads are pure input with no output tokens.

How much does Gemini 2.0 Flash outperform GPT-4o on benchmarks?

Gemini 2.0 Flash scores higher overall (18.5 vs 17.3). Gemini 2.0 Flash leads on GPQA (0.62 vs 0.54) and AIME (0.33 vs 0.15), with both within 5% on MMLU-Pro. If mathematical reasoning matters, Gemini 2.0 Flash's AIME score of 0.33 gives it an edge.

How much more context can Gemini 2.0 Flash handle than GPT-4o?

Gemini 2.0 Flash has a much larger context window — 1,000,000 tokens vs GPT-4o at 128,000 tokens. That's roughly 1,333 vs 170 pages of text. Gemini 2.0 Flash's window can handle entire codebases or book-length documents; GPT-4o works better for shorter inputs.

Is Gemini 2.0 Flash worth choosing over GPT-4o on value alone?

Gemini 2.0 Flash offers dramatically better value — $0.000049 per intelligence point vs GPT-4o at $0.0013. Gemini 2.0 Flash is both cheaper and higher-scoring, making it the clear value pick. You don't sacrifice quality to save money with Gemini 2.0 Flash.

Which model benefits more from prompt caching, Gemini 2.0 Flash or GPT-4o?

With prompt caching, Gemini 2.0 Flash is dramatically cheaper — 31x less per request than GPT-4o. Caching saves 42% on Gemini 2.0 Flash and 28% on GPT-4o compared to standard input prices. Gemini 2.0 Flash benefits more from caching. If your workload has repetitive prompts, Gemini 2.0 Flash's cache discount gives it a bigger cost advantage than list prices suggest.
