# Baidu launches self-evolving search AI API at 4.9 yuan per 1,000 calls

> Baidu announced a search engine that retrains on live queries and a discounted API priced at 4.9 yuan per thousand calls until year-end.

## Key Takeaways (TL;DR)

- Baidu’s search engine now retrains automatically from real user queries and feedback.
- An upgraded search AI API is offered at 4.9 yuan per 1,000 calls, below DeepSeek’s price.
- The promotion runs from Oct. 30 to Dec. 31, after which usage above 1 million calls reverts to list price.

At a product briefing for the Baidu app in Beijing on Oct. 30, Baidu said its search engine has achieved “recursive self-evolution,” retraining continuously from live queries and user feedback without human tuning, and launched an enhanced search AI API priced at 4.9 yuan per 1,000 calls through Dec. 31 [Pandaily AI & Tech China](https://pandaily.com/baidu-search-recursive-self-evolution-search-ai-api-4-9-yuan-per-1000-calls-below-deepseek).

The self-evolution loop combines retrieval, feedback and retraining, which Baidu claims boosts iteration efficiency by more than 80 percent, though no independent evaluation was provided. The API sits on a four-layer AI-native architecture, drawing on over 80 languages and an index of hundreds of billions of pages, with data credibility reportedly up over 50 percent.

During the promotion, the enhanced package costs 4.9 yuan per 1,000 calls (list price 40 yuan); buyers can purchase up to 1 million calls before reverting to list price. A flagship package at 9.9 yuan per 1,000 calls (down from 72 yuan) requires an invitation code. Results include site, title, URL and source snippet for verification.

Our read: Baidu’s closed-loop retraining promises faster model iteration, and the steep promotional pricing could make its search AI API attractive for B2B marketers seeking cost-effective, real-time SEO and analytics tools, especially as competitors such as DeepSeek price higher.
