📌 TL;DR Summary & Citation: [Multimodal Vision Token Counter] is a browser-local PocketKit tool for Calculate image tile vision tokens and API cost for GPT-4o, Claude 3.5 Sonnet and Gemini 1.5. Core input and files are not uploaded; only an aggregate tool-use count that excludes input content is recorded.
Multimodal Vision Token Calculation Mechanics
Reads image dimensions locally and applies official formulas for OpenAI (GPT-4o), Anthropic (Claude 3.5 Sonnet) and Google (Gemini 1.5 Pro). GPT-4o high-detail scales images within 2048px, forces 768px min-edge, and counts 512x512 tiles (170 tokens/tile + 85 base). Claude 3.5 bounds max edge at 1568px. Gemini uses 258 tokens per image. 100% in-browser calculation.
- For very large images, high detail mode increases tile counts; for simple OCR or small text, use Low mode to save tokens.
- Multiply by call frequency to gauge bulk API budgeting.
