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.

Baichuan's official pricing page lists Baichuan4 Air at roughly
$0.138/M unified. That comes from 0.00098 yuan per 1K tokens converted at 7.10 CNY/USD, and the same rate applies to both prompt and completion tokens.Q · 02 Is Baichuan4 Air Baichuan's cheapest current paid model? +

Q · 03 Does it have cache pricing? +
No separate cache-hit discount is listed for Baichuan4 Air. AI//COST therefore treats cached input as the same rate as normal input instead of guessing at an unpublished discount.
Q · 04 How does it compare with Gemini 2.5 Flash? +
Baichuan4 Air is cheaper on raw token price: about
$0.138/M unified versus Gemini 2.5 Flash's $0.30/M input and $2.50/M output. Gemini still brings a very different global multimodal feature set and a much larger context window.Q · 05 Is there a public batch-discount row? +

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 is set by Baichuan's server-side token count and can differ for Chinese, code, or mixed-language prompts.
