Estimate · baichuan-tokenizer-estimate · ≈3.85 chars/token Auto-counts as you type
This is a chars-per-token approximation, not a real tokenizer. Actual tokens vary by language, code density, and tool-call overhead — counts are typically ±10–20% off for English prose, more for code or non-Latin scripts. For exact billing, use the vendor's official tokenizer.

Frequently asked.
Practical pricing questions for Baichuan-M2, especially where its low input price can hide a much higher output side.
Q · 01 What is Baichuan-M2 priced at? +
Baichuan's official pricing page lists Baichuan-M2 at about
$0.282/M input and $2.817/M output. Those USD figures come from 0.002/0.02 yuan per 1K tokens converted at 7.10 CNY/USD.Q · 02 Why does the output side look so expensive? +
Baichuan-M2 uses a 10x spread between input and output on the public table. That keeps prompt-heavy workloads cheap, but any completion-heavy use case can end up much less economical than the headline input number suggests.
Q · 03 Does Baichuan-M2 have prompt-cache pricing? +
No separate cache-hit discount is listed for Baichuan-M2 on the public pricing page. AI//COST therefore treats cached input as the same rate as normal input instead of inventing an unpublished discount.
Q · 04 How does it compare with Baichuan-M2-Plus? +
Baichuan-M2-Plus is much pricier at about
$1.41/M input and $4.23/M output. On the standard 92/8 blend, Baichuan-M2 lands around $0.48/M versus about $1.63/M for M2-Plus.Q · 05 Is it cheaper than Gemini 2.5 Flash on effective cost? +
Not always. Baichuan-M2 is cheaper on input but more expensive on output, while Gemini 2.5 Flash carries
$0.30/M input, $0.03/M cached input, and $2.50/M output. Under the standard 92/8 plus 82% cache assumption, Gemini 2.5 Flash still comes out lower on effective blended cost.Q · 06 How accurate is the tokenizer estimate? +
The browser widget uses a
baichuan-tokenizer-estimate chars-per-token approximation for English planning. Real billing comes from Baichuan's API usage counters and can differ for Chinese, code, or mixed-language prompts.
