LLM Abacus is a price table for large language model APIs. It covers 57 models from 16 vendors, including OpenAI, Anthropic, Google, xAI, DeepSeek, Zhipu, Moonshot, Alibaba, ByteDance, Baidu, Tencent and MiniMax, with input, output and cached-input prices side by side. Overseas vendors keep their USD list price and are converted through a single exchange-rate constant, so both currencies stay visible. Paste a prompt into the estimator and it counts tokens and gives you the cost per model. There is also a monthly bill calculator, a routing tool that mixes a cheap model with a flagship one to show what the split saves, per-model detail pages, and a live latency board. An automated job re-checks prices every day and flags anything that has drifted.
