Common questions
Is Gemini cheaper than GPT?
On 10 November 2026, the median Google model on this list costs $0.575 per million input tokens and $3.00 per million output tokens, against $2.00 and $10.00 for OpenAI. By that measure Google is cheaper, but compare the specific models you would use, since both providers sell models at very different price points.
What is the cheapest Gemini model compared with the cheapest GPT model?
The cheapest Google model on this list is Gemma 3 4B at $0.05 in and $0.10 out per million tokens. The cheapest OpenAI model is gpt-oss-20b at $0.02 in and $0.03 out.
Which has the larger context window, Gemini or GPT?
The largest Gemini context on this list is 1.05M tokens (Gemini 4 Argon) and the largest GPT context is 1.05M tokens (GPT-6.1 Terra Pro).
How should I choose between Gemini and GPT for a production agent?
Price per token is one input. Run both on a set of your own real cases, count how often each needs a retry or a human check, and compare the total cost of a correct answer rather than the cost of a token.
Choosing a model for a production agent
Price is one input. Quality on your own cases, latency and the cost of retries decide the rest. Tell me what you are building.
