About Token Counting
Token counting is essential for working with large language models (LLMs) like GPT-4, GPT-3.5 Turbo, and Llama. Each model has a specific token limit, and understanding how many tokens your text uses helps you:
- Stay within model context limits
- Optimize API costs (as many providers charge per token)
- Improve prompt engineering by understanding token efficiency
- Debug issues related to context length
Token Limits by Model
| Model | Max Tokens | Tokenizer |
|---|---|---|
| GPT-4 | 8,192 | cl100k_base |
| GPT-4o | 128,000 | o200k_base |
| GPT-3.5 Turbo | 4,096 | cl100k_base |
| Llama 3 | 8,192 | Llama tokenizer |
