Yesterday I did some testing on the cost to solve the same simple problem on openrouter with different models using cline. Simple problem but it had a few nuances to solve it properly and so required reasoning.
After reading comments like this I was expecting (hoping?) that DeepSeek or similar would be cheaper.
However I was surprised that DeepSeek v4 cost about 5.5x GPT-5.4 to solve the problem.
That doesn't sound right. Were you using the actual Deepseek provider? The one time I spent 3 dollars on Deepseek in a day, I had 615k output tokens, 96M cache hit input tokens, and 5M cache miss output tokens.

- Deepseek-v4-pro-medium cost $2.47 - GPT-5.4-medium cost $0.45 - GPT-5.5-low was $0.86
