Description
ERNIE X1 is a reasoning model from Baidu ERNIE. Webparam does not stock this model yet and can source it on request — tell us what you need it for and we will come back with availability and a price. Baidu ERNIE’s stated focus is china's longest-running LLM lineage. The weights are not published, so it is API-only.
Capabilities
- Reasoning
- Spends extra billed tokens thinking before it answers, trading latency and cost for accuracy.
- Tool calling
- Calls functions you define and returns their arguments as structured data, the basis of agents.
- Streaming
- Emits tokens as they are generated, so answers appear progressively rather than all at once.
