Hey PH 👋 I built this after spending way too much time in spreadsheets trying to figure out which LLM API to use. The pricing gap between the cheapest and most expensive model right now is 178x — and providers change prices every few weeks without announcements. opcmake.com lets you: → Enter your monthly token usage (or pick a preset) → Compare up to 5 models side by side → Adjust for prompt caching and batch processing → See exactly how much each model costs per month Some things I learned while building this: • Mistral dropped prices 4x recently and barely anyone noticed • DeepSeek cache reads are 120x cheaper than uncached input — if you're not caching your system prompts you're burning cash • Claude's new Sonnet 5 has intro pricing that expires Aug 31, then goes up 50% Built with Next.js, static pages, hosted on Vercel. Zero tracking, no signup, no paywall. I just wanted a tool that did the math. Would love feedback from anyone paying for LLM APIs — what features would actually make this useful day to day?
