GLM-5 (Reasoning) Token Counter & Cost Calculator
Count tokens for GLM-5 (Reasoning) and estimate the exact API cost — $1.00
per 1M input tokens, $3.20 per 1M output tokens — using a real
o200k_base BPE tokenizer. Everything runs in your browser; nothing is uploaded.
Counts are exact for OpenAI models (o200k_base is GPT-4o/4.1/5's tokenizer). For Claude, Gemini and other vendors — whose tokenizers are not public — treat the count as a close estimate (typically within ±15%).

How is GLM-5 (Reasoning) API cost calculated?
Cost = (input tokens ÷ 1,000,000) × $1.00 + (output tokens ÷ 1,000,000) × $3.20 — GLM-5 (Reasoning)'s official per-1M-token prices from Artificial Analysis.
Does this cover every reasoning-effort tier of GLM-5 (Reasoning)?
Pricing shown is for the merged representative tier. GLM-5 (Reasoning) groups 2 reasoning-effort variants: GLM-5 (Reasoning), GLM-5 (Non-reasoning).
