TL;DR: I pay, I always try to use SOTA models if I can.

I pay for them; until last week, this was almost entirely[0] pay-as-you-go use of API keys via TypingMind (for chat) and Aider (for coding). The QR code project I linked was made by Aider. Total cost was around $1 IIRC.

API options were, until recently, very cheap. Most of my use was around $2 to $5 per project, sometimes under $2. I mostly worked with GPT-4, then Sonnet 3.5, briefly with Deepseek-R1; by the time I got around to testing Claude Sonnet 3.7, Google released Gemini 2.5 Pro, which was substantially cheaper, so I stuck to the latter.

Last week I got myself the Max plan for Anthropic (first 5x, then the 20x one) specifically for Claude Code, because using pay-as-you-go pricing with top models in the new "agentic" way got stupidly expensive; $100 or $200 per month may sound like a lot, but less so when taking the API route would have you burn this much in a day or two.

[0] - I have the $20/month "Plus" subscription to ChatGPT, which I keep because of gpt-4o image generation and o3 being excellent as my default model for random questions/problems, many of them not even coding-related. I could access o3 via API, but this gets stupidly expensive for casual use; subscription is a better deal now.
