Baidu: ERNIE-5.5-Flash-Preview (free)

ERNIE-5.5-Flash-Preview sits in Baidu's ERNIE line, which the catalog attributes to Baidu under the ernie family naming. As a preview-tagged Flash variant, it is positioned as a fast, general-purpose text model rather than a heavyweight research release, and it is exposed through Kilo Gateway alongside a broad catalog of hosted models for coding-agent and chat workflows. Nothing in the available evidence indicates published benchmark tables, parameter counts, or a technical report for this exact preview variant, so it is best evaluated as an early-availability release of the Flash tier rather than a fully documented flagship checkpoint.

Practically, the entry is aimed at users who want a quick, inexpensive text model for everyday assistant work and for driving agentic tooling inside editors, terminals, and cloud sessions, where the surrounding platform supplies integrations for tool use, structured output, and reasoning-oriented tasks. Because it is a preview build, expect iteration and behavioral adjustment over time as the ERNIE 5.5 generation matures, and treat it as a practical option for high-volume, latency-sensitive prompting rather than as a benchmark-verified frontier system.
