Common questions
Is DeepSeek cheaper than GPT?
On 25 September 2026, the median DeepSeek model on this list costs $0.27 per million input tokens and $0.89 per million output tokens, against $1.75 and $10.00 for GPT. By that measure DeepSeek is cheaper, but compare the specific models you would use, since both providers sell models at very different price points.
What is the cheapest DeepSeek model compared with the cheapest GPT model?
The cheapest DeepSeek model is DeepSeek V4 Flash 0423 at $0.0482 in and $0.0963 out per million tokens. The cheapest GPT model is gpt-oss-20b at $0.018 in and $0.09 out.
Which has the larger context window, DeepSeek or GPT?
The largest DeepSeek context on this list is 1.31072M tokens (DeepSeek V4 Flash 0731) and the largest GPT context is 1.05M tokens (GPT-6 Luna Pro).
How should I choose between DeepSeek 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.
