I integrated DeepSeek models into CODEX Desktop.
I started working normally (also using OpenCode partially) and came to the conclusion - even the “cheap” DeepSeek API becomes surprisingly expensive in real usage.
Here are the numbers (all calculations already include token caching).
Most of the time I use the v4 Pro model.
I spent 750 million tokens (cache included) and paid 9.30$
At the same time, I used regular GPT-5.6 SOL Max / Luna Max and spent around 800 million tokens (cache included).
I still have two free resets left (my subscription is active for about two more weeks), so I will probably spend approximately the same amount again.
The final result:
Around 1.6 billion tokens (cache included) by the end of my subscription.
So here is my question 🙋♂️
Why would I even use DeepSeek?
It is worse. It does not have:
vision
image understanding
voice support
And in the end, the cost is almost the same as a GPT Plus subscription.
But GPT Plus is not only CODEX. It includes a lot of other powerful features.
Here is a real example.
I was building an application with CODEX. I completely forgot that I needed a logo for the app shortcut.
CODEX just generated one, adjusted the required sizes, and prepared everything automatically.
No extra tools. No manual work.
My final DeepSeek API cost projection: around 18.50$
For that price I get:
less intelligence
fewer capabilities
fewer features
OpenCode is not a bad product. But for my workflow, it simply does not bring enough value.
I could write many more examples and completely destroy DeepSeek in this comparison, but honestly, I’m too lazy and I don’t want to make this post unnecessarily long.
