How do I count tokens for an LLM?
Paste any text to get a rough token estimate for GPT-4, Claude, Gemini, and Llama models. Uses a character-based heuristic (~4 chars per token for English), not each model’s real tokenizer — treat counts as approximate. Prices shown are input-only list prices as of September 2026 and may be outdated; check provider docs before budgeting.
