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.

Frequently asked.

Practical pricing questions for Baichuan-M2-Plus, especially around the pricing parity with M3 and the extra medical-search charge.

Q · 01 What is Baichuan-M2-Plus priced at? +
Baichuan's official pricing page lists Baichuan-M2-Plus at about $1.41/M input and $4.23/M output. Those USD figures come from 0.01/0.03 yuan per 1K tokens converted at 7.10 CNY/USD.
Q · 02 Why does Baichuan-M2-Plus cost the same as Baichuan-M3? +
On the current public table, both rows carry the same token prices: $1.41/M input and $4.23/M output. That means M2-Plus no longer offers a cheaper on-ramp relative to M3, so the decision is about model behavior and integration history rather than list price.
Q · 03 What is the medical-search surcharge? +
Baichuan notes that Baichuan-M2-Plus can automatically trigger a medical-search service billed separately at 0.03 yuan per call. At 7.10 CNY/USD, that is roughly $0.0042 per triggered call and sits outside the token quote board.
Q · 04 Does Baichuan-M2-Plus have prompt-cache pricing? +
No separate cache-hit discount is listed for Baichuan-M2-Plus on the public pricing page. AI//COST therefore treats cached input as the same rate as normal input instead of inventing another billing tier.
Q · 05 How does it compare with Baichuan-M2? +
Baichuan-M2 is much cheaper at about $0.282/M input and $2.817/M output. On the standard 92/8 blend, Baichuan-M2-Plus lands around $1.63/M versus about $0.48/M for Baichuan-M2.
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.
