I spent $638 on AI coding agents in 6 weeks.

1 pointsnthypes7mo ago8 comments

I just got my Cursor invoices and I'm genuinely shocked. Between October and early November, I've burned through $638 on AI coding assistance. That's more than some cloud bills.

Context: I'm an Founder & CTO building an AI-First CRM product.

Here's what happened:

October: Started the month thinking "I'll stay within the Pro limits, no problem." By mid-month, Cursor hit me with a $280 invoice. By month end? $348.56 total in on-demand charges. I literally maxed out the $400 limit.

November: It's only November 12 and I've already been invoiced $289.38:

Cost per request: Claude 4.5 Sonnet Thinking ranges from $0.02 to $0.06 depending on context size. Doesn't sound like much until you realize you're hitting it 200+ times per day.

I tried 7 different models (GPT-5, Gemini 2.5 Pro, Cheetah, etc.) thinking I'd save money. Claude still ate 85% of my budget because, honestly, it's the best.

Am I more productive? Absolutely. Is it worth $638 every 6 weeks? Idk. That's $5,500+ annually just for code assistance.

So I'm curious:

What are YOU spending? Am I an outlier or is this the new normal?

Have you changed behavior to cut costs? (Using faster models? Being more selective? Bringing your own API keys?)

At what price point would you stop? $100/month? $500? $1000?

Is anyone actually staying within the included limits? Or is that just marketing?

I feel like we're in this weird phase where the value is obvious but the pricing model hasn't stabilized.

Would love to hear how others are navigating this.

I just use claude code max (125/month flat) with no problems like this. I constantly have multiple agents doing things on clusters figuring out problems, writing codes, or otherwise doing research for me (I am a scientist). Maybe you should swich from loser Cursor to winner Claude? Haha. And anyways, you are a founder, is 638$/6weeks affordable in your budget? It is up to you to decide what you think is a reasonable expense on your adventure towards profitability.

Thanks for the input! I'm checking on Claude Code Max now - from what I'm seeing, even the $200/month plan has weekly rate limits (240-480 hours of Sonnet 4, 24-40 hours of Opus 4 per week).. so not quite unlimited tokens either, though definitely more predictable billing.

$638/6 weeks won't make me broke, but here's my main issue: for me it's about the value-to-token ratio feeling off.

What bugs me most is that many of those 340M tokens feel wasteful? Like the LLM will use 50k tokens exploring dead ends before finding a solution that could have been expressed in 5k tokens. The productivity gain is real, but it feels like I'm paying 10x more than what should be "fair" for the actual value delivered.

Maybe this is just the current state of AI coding - the models need that exploration space to get to the answer. Or maybe I need to get better at constraining the context and being more surgical with my prompts.

For me as a founder, it's less "can I afford this" and more "does this pricing model make sense long-term?" If AI coding becomes a $5-6k/year baseline expense per developer, that changes a lot of unit economics, especially for early-stage companies.

Are you finding Claude Code Max more token-efficient for similar tasks, or is it just easier to stomach because the billing is flat?

i think when you are testing out ideas you cannot also be thinking about how efficient that is. it doesn't make a lot of sense unless the problem you are trying to solve is efficiency. So like, I get your point, but I don't think anyone is wasting tokens, the LLM explores different solutions and arrives at ones that work. You seem to not want to pay for the tokens used on bad solutions, but they were useful to find the actual solutions. I also think that there are plenty of software licenses that we pay for in my work that are multiple times 5-6k/year and yet all our software is much cheaper than the salaries that cover our developers. Good developer tools are always worth it imo.

And was it worth it? What were you able to achieve with the LLM-support you payed for? How much time did you save?

I did experiments with Claude Sonnet and Opus and also with Gpt-5, the latter via my Perplexity subscription. My experience with Claude was mixed; most output required significant re-work which mostly consumed the time savings enabled by Claude. In contrast, Gpt-5 was able to generate code for several complex problems and made different transpilations for me, and the generated code usually compiles and correctly runs up front, all covered by my Perplexity subscription.

I've asked Sonnet 4.5 (Cursor) to generate some stats based on my cursor CSV file usage. Here it is the output:

Key Findings from Your Cursor Usage Here are the most interesting insights from your usage data:

Cost Summary

Total Cost: $928.45 over 70 days

Average per Request: $0.06

Cost per Task (Request): Ranges from $0.00 to $2.78, with 65.7% costing under $0.05

Projected Monthly Cost: ~$416 (based on average daily spend of $13.86)

Request Patterns

Requests per 5 Hours: Average 70.7, ranging from 1 to 451

Average Time Between Requests: 6 minutes 33 seconds

Median Time Between Requests: Just 13 seconds (shows bursts of activity)

Peak Activity: 1-2 PM (10.4% of all requests at 1 PM)

Busiest Day: Saturday with 21.7% of requests

Token Efficiency

Average Tokens per Request: 83,371 tokens

Median Tokens per Request: 38,342 tokens

Average Output per Request: 876 tokens

Cache Hit Rate: 88.8% (excellent! saves money)

Cost per 1,000 Tokens: $0.0009 (very efficient due to caching)

Cost per 1,000 Output Tokens: $0.14

Notable Stats

Most Expensive Request: $2.78 using 6.8M tokens (mostly cached)

Total Hours of Active Usage: 1,692 hours (~9 requests/hour)

Most Used Models: claude-4.5-sonnet-thinking, claude-3.5-sonnet, and others

Your cache hit rate of 88.8% is excellent and is saving you significant costs! Without caching, your costs would be much higher.

I totally agree with the closing questions and statements here.

Yes, there is an apparent fluctuation in pricing for said tokens/credits/etc.. and they are just finding the sweet spot.

I primarily use the https://www.warp.dev/ terminal and they have just released a new plan which outwardly states lower cost per request.

They mentioned 'At full usage, the plans didn’t scale sustainably'. This is encouraging to know.

Right now, I'm looking around and trying out. Nice read, thanks.

Also interesting is what it will cost if you do or don't train yourself to use it. You can't be a very good spell caster if you don't practice as much as the next wizard. Also, from now on everything you do will be this expensive :P
