What it does

Estimate AI API costs, token usage, and monthly budgets for OpenAI, Gemini, Claude, embeddings, images, audio, and vector storage.

TokenMath turns prompts, model rates, and product usage into practical cost projections for OpenAI, Gemini, Anthropic, and the rest of your AI stack. Explore source-linked pricing, standard workload comparisons, use-case examples, developer snippets, and concise cost definitions. See the rates, token assumptions, and formula behind every estimate. Every result identifies its pricing source and last verified date. Move from one request to daily, monthly, and yearly projections. Use calculators for language models, image generation, audio, embeddings, vector storage, fine-tuning ROI, prompt tokens, latency, API budgets, and SaaS unit economics.

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
