Can I cancel my ChatGPT Plus subscription in favour of DeepSeek V3 API ?

I am impressed by DeepSeek and makes me to feel I am spending lot for ChatGPT plus. I am from India and $23 is very higher for us.

I am thinking about cancelling ChatGPT Plus and use the DeepSeek chat and sometimes API.

My only concern is, I am a using it for coding mostly, and I ask code help in Android, Flutter, JS and Python.

So, how DeepSeek excels in code generation for the above stack?

Also, how does the O1 and upcoming O3 performs in coding and other human language tasks (translation etc) when compared with DeepSeek V3?
