Baidu API pricing ranges from $0.070 to $0.42 per 1M input tokens. Output tokens cost more than input on every model. Prices are per 1 million tokens (1M ≈ 750,000 words). Use the calculator above to estimate your monthly spend at your actual workload.
ERNIE 4.5 21B A3B Thinking is the lowest-priced Baidu model with public pricing at $0.070/1M input tokens. It suits high-volume tasks where cost matters most — classification, extraction, summarization, and similar workloads that don't need frontier reasoning.
ERNIE 4.5 VL 424B A47B is Baidu's highest-tier model at $0.42/1M input. It delivers the most sophisticated reasoning, instruction-following, and nuance. For workloads that don't require frontier performance, a mid-tier model typically cuts inference costs substantially.
ERNIE 4.5 21B A3B Thinking support deep reasoning mode, which improves performance on multi-step coding, debugging, and code review. For simpler autocomplete or snippet generation, a faster, cheaper model often delivers acceptable quality at a fraction of the cost.
ERNIE 4.5 21B A3B Thinking, ERNIE 4.5 21B A3B, ERNIE 4.5 VL 28B A3B and 2 more support function calling (tool use), required for agentic workflows. Agents need a model that reliably follows structured output schemas — test with your specific tool definitions before committing to production volumes.
Yes — ERNIE 4.5 VL 28B A3B, ERNIE 4.5 VL 424B A47B accept image input alongside text. You can pass screenshots, photos, charts, and documents for analysis. Vision adds no separate line-item on most Baidu models — you're billed for the token equivalent of the image.
Yes — Baidu supports prompt caching (discounts for repeated context) and batch processing (accept a delay, cut costs ~50%). These rates appear in the table above under "Cached /1M" and "Batch /1M." Caching pays off quickly if your prompts share a long system prompt or document prefix across many calls.
Baidu has historically adjusted prices when launching new model generations, often cutting rates to stay competitive. Buzzi.ai snapshots pricing daily — you can subscribe to price-drop alerts on any Baidu model using the "Alert me" button on its detail page.
