Calibrated · measured on the vendor's tokenizer · 2026-06-10 Auto-counts as you type

Counts use a chars-per-token calibration measured on the vendor's own published tokenizer (baichuan-inc/Baichuan-M2-32B, 2026-06-10). English prose is typically within a few percent; code and non-Latin scripts tokenize heavier. For billing-exact counts use the vendor's count-tokens API.

Baichuan4 Air API pricing FAQ.

Practical pricing questions for Baichuan4 Air, especially when comparing Chinese-market budget models.

Q · 01 What is Baichuan4 Air priced at? +
Baichuan's official pricing page lists Baichuan4 Air at roughly $0.1458/M unified. That comes from 0.00098 yuan per 1K tokens converted at 6.7209 CNY/USD, and the same rate applies to both prompt and completion tokens.
Q · 02 Is Baichuan4 Air Baichuan's cheapest current paid model? +
Yes on the current public pricing page. Baichuan4 Air is much cheaper than Baichuan4 Turbo, Baichuan4, Baichuan-M3-Plus, and Baichuan-M3 on a per-token basis.
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 AI//COST therefore treats cached input as the same rate as normal input instead of guessing at an unpublished discount.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 $0.1458/M unified versus Gemini 2.5 Flash's $0.30/M input and $2.50/M output. Since September 18, 2026 Gemini 2.5 Flash is open only to accounts that used it before. 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? +
No separate batch-discount row appears on Baichuan's official pricing page for Baichuan4 Air. Treat the quote board as list pricing unless Baichuan publishes another billing mode.
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.
