What it does
Tokenomy predicts token usage and dollar cost for GPT-4o, Claude, and other LLMs before you make the API call. A VS Code sidebar, CLI, and LangChain callback surface estimates and cost-saving tips so dev teams ship confidently without surprise bills.
Tokenomy is the economic runtime for LLMs and AI agents. Agent-level cost attribution, budgets enforced in the request path, and an effective-dated price record behind every number. BYOK across OpenAI, Anthropic, Google, xAI and open-weight endpoints.
Tokenomy meters, budgets, routes and charges back every model call across OpenAI, Anthropic, Google, xAI and open-weight endpoints. Bring your own keys — provider spend stays on your accounts. Two doors: engineering teams who own the bill, and finance teams who own the margin and the forecast. Last updated 2026-09-12 . Model pricing is refreshed twice daily. Agent-level attribution down to the step and tool call. Budgets with hard and soft caps that fire before spend, not after. Smart routing to the cheapest model that still clears your quality and latency bar. Gross margin per customer and per feature, spend forecasts with a stated confidence band and month-end accrual, commitment…from tokenomy.ai

Token price calculator for 400+ LLMs2024 · github.com · ▲268Hey HN! Tokencost is a utility library for estimating LLM costs. There are hundreds of different models now, and they all have their own pricing schemes. It’s difficult to keep up with the pricing changes, and it’s even more difficult to estimate how much your prompts and completions will cost until you see the bill. Tokencost works by counting the number of tokens in prompt and completion messages and multiplying that number by the corresponding model cost. Under the hood, it’s really just a simple cost dictionary and some utility functions for getting the prices right. It also accounts for…
Price Per Token – LLM API Pricing Data2025 · pricepertoken.com · ▲339The LLM providers are constantly adding new models and updating their API prices. Anyone building AI applications knows that these prices are very important to their bottom line. The only place I am aware of is going to these provider's individual website pages to check the price per token. To solve this inconvenience I spent a few hours making pricepertoken.com which has the latest model's up-to-date prices all in one place. Thinking about adding image models too especially since you have multiple options (fal, replicate) to use the same model and the prices are not always the same.

Tapflow 2.0▲1,125We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
