Estimate · ernie-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 ERNIE 4.5 Turbo pricing questions, with Baidu's published CNY rates kept separate from conversion and workload assumptions.

Q · 01 What is ERNIE 4.5 Turbo priced at? +
On Qianfan it lists CNY 0.8/M input, CNY 3.2/M output, and CNY 0.2/M cache-hit input, stored here as $0.118/M, $0.472/M, and $0.0295/M at 1 CNY = $0.1475.
Q · 02 How large is the cache discount? +
Cache-hit input is CNY 0.2/M against a base input of CNY 0.8/M - a 75% discount. For cache-heavy agentic workloads, that pulls the effective blended cost down to roughly $0.08/M.
Q · 03 Is the 128K variant more expensive than 32K? +
No. ERNIE 4.5 Turbo has 32K and 128K context variants at the same per-token rate, unlike the ERNIE 5.x models which are tiered by input length.
Q · 04 How does it compare with ERNIE 5.1? +
ERNIE 5.1 is Baidu's frontier tier at $0.59/$2.655, roughly 5x the input price of ERNIE 4.5 Turbo. Use Turbo for volume, ERNIE 5.1 for the hardest tasks.
Q · 05 Does this page include tax? +
No. AI//COST stores Baidu's public pre-tax CNY list price and converts to USD for cross-vendor comparison. Enterprise discounts and Baidu AI Cloud resource packages are outside this page.
