Paste text. See tokens. See cost.

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 Baichuan3-Turbo 128K, especially around the cost of buying more context.

Q · 01 What is Baichuan3-Turbo 128K priced at? +
Baichuan's official pricing page lists Baichuan3-Turbo 128K at about $3.38/M on a unified basis. That USD figure comes from 0.024 yuan per 1K tokens converted at 7.10 CNY/USD.
Q · 02 Why does the 128K row cost double the 32K row? +
Baichuan's public table prices the 128K row at exactly twice the 32K Baichuan3-Turbo rate: $3.38/M versus $1.69/M. You are paying for the larger context window, not for a different input/output split.
Q · 03 Does Baichuan3-Turbo 128K have prompt-cache pricing? +
No separate cache-hit discount is listed for Baichuan3-Turbo 128K on the official pricing page. AI//COST therefore sets cached input equal to the normal token rate instead of inventing another billing mode.
Q · 04 Is it cheaper than Baichuan4? +
Yes by a wide margin. Baichuan4 is about $14.09/M unified on the same pricing page, while Baichuan3-Turbo 128K is about $3.38/M unified.
Q · 05 When does the 128K variant make sense? +
Only when you genuinely need the longer context. If your workload fits in 32K, the standard Baichuan3-Turbo row cuts the unified token rate in half.
Q · 06 How accurate is the tokenizer estimate? +
The browser widget uses a baichuan-tokenizer-estimate chars-per-token approximation for English text. Real billing comes from Baichuan's API usage counters and can differ for Chinese, code, or mixed-language prompts.
