Stop Overpaying for LLM APIs: A Token Cost Calculator for 2026

The LLM API Price War

In 2026, the price war between OpenAI (GPT-4o), Anthropic (Claude 3.5), and DeepSeek has driven costs down, but it also made pricing models extremely confusing. Context caching, batch API discounts, and output token multipliers make it hard to estimate real-world costs.

The OmniTool LLM Cost Calculator

We built the LLM API Cost & Token Calculator to solve this.
Paste your prompt, and it will:

1. Estimate the token count (using Tiktoken/Claude heuristics).
2. Calculate the exact cost for GPT-4o, Claude 3.5 Sonnet, and DeepSeek.
3. Compare costs instantly without signing up for a dashboard.
