Common questions
Is Grok cheaper than GPT?
On 10 November 2026, the median xAI model on this list costs $1.25 per million input tokens and $2.50 per million output tokens, against $2.00 and $10.00 for OpenAI. By that measure xAI is cheaper, but compare the specific models you would use, since both providers sell models at very different price points.
What is the cheapest Grok model compared with the cheapest GPT model?
The cheapest xAI model on this list is Grok Build 0.1 at $1.00 in and $2.00 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, Grok or GPT?
The largest Grok context on this list is 2M tokens (Grok 4.20 Multi-Agent) and the largest GPT context is 1.05M tokens (GPT-6.1 Terra Pro).
How should I choose between Grok 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.
