I went from 408 euros/month of AI spending to 28 in the span of one year.

The 20 euros GPT plan with GPT 6 Luna (and Astra for doing the tough stuff) and OpenCode Go (8 euros) offer me both way more intelligence and tokens than spending 400 euros just at the beginning of the this summer did.

Today I worked two hours with GPT 6 Luna, have been very productive tackling some hard stuff and...my weekly usage went from 57% to 56%?

You really don't need to use the strongest model for everything. And even chinese open models are effectively few months old sota. You can use mimo 2.6 or DS 4.1 flash on 8 $/months OpenCode and barely ever have to worry about consumption.
