How accurate is the token count?

Token counts use word-based heuristics (~1.3 tokens per word). Results are approximate.

Which models are supported?

GPT-4o, GPT-4o Mini, GPT-4 Turbo, GPT-3.5 Turbo, Claude 3.5 Sonnet, Claude 3 Opus, Gemini 1.5 Pro, and LLaMA 3.1/3.2 variants.

Is my text sent to any server?
