Understanding AI Token Limits: What You Need to Know

What Are Tokens?

Tokens are the basic units AI models use to process text. Think of tokens as pieces of words:

• 1 token ≈ 0.75 words (English)

• 100 tokens ≈ 75 words

• 1,000 tokens ≈ 750 words

• "Hello world" = 2 tokens

• "ChatGPT is amazing" = 4 tokens

Two Types of Limits

1. Context Window (How Much AI Can Remember)

• Maximum tokens AI can process in single conversation

• Includes your messages + AI responses + uploaded files

• Claude: 190k-200k tokens

• ChatGPT: 128k tokens

• Gemini: 1M tokens (2M for some models)

2. Usage Limits (How Much You Can Use)

• Message caps per hour/day/week

• Rate limiting during high demand

• Reduced limits when hitting capacity

• Varies by subscription tier

Why This Matters Now

Late 2025/Early 2026 Changes:

• Claude decreased weekly usage limits approaching faster

• Users hitting limits more frequently
