ChatGPT vs Gemini Price Comparison

Among the currently available LLMs, there are mainly two that offer cloud-based services.
One is OpenAI (or Azure OpenAI), known as ChatGPT.
The other is Google's Vertex AI - Palm2 & Gemini.

This document does not aim to compare performance, but rather focuses on a simple price comparison.

Note: Although the official websites indicate pricing per 1,000 tokens/1,000 characters,
both have been converted to 1 million tokens/1 million characters due to excessively long decimal places.

The 'k' within the parentheses represents the maximum number of tokens for each.
