Model Card

ERNIE 5.5 Flash Preview is a text model from Baidu and the newest foundation model in the ERNIE family, with 280 billion total parameters.

Baidu lists improvements in coding, agentic tasks, knowledge work, and deep research. The model reasons before it answers by default. It supports tool calling and structured output, and it accepts up to 1,024,000 tokens of context with up to 921,600 output tokens.

Baidu has not published benchmark scores for this preview. Its published numbers cover only the related ERNIE 5.5 Flash Base checkpoint, released on November 5, 2026.

At $0.28 per million input tokens and $1.13 per million output tokens, it fits developers building coding assistants, agents, and long-document research tools who need a very long context window at a low per-token cost.

ERNIE Light DT 1.0

ERNIE Light DT 1.0 is a text-only large language model from Baidu, offered through Baidu Qianfan's international API. Baidu says it is built on open-source GLM models and draws on research from Baidu Search's Lightning model. Its main feature is Baidu Sparse Attention (BSA) with feedback-driven history compression. Baidu says this lowers KV cache storage and compute costs while maintaining model performance. The model accepts up to 1,024,000 input tokens and can return up to 131,072 output tokens. The API supports tool calling, structured JSON output, and adjustable reasoning effort (max, high, low, or none). Baidu has not published benchmark scores. It fits developers building agents, long-document analysis, or multi-turn workflows that need a very large context window. At $1.13 per million input tokens and $3.94 per million output tokens, it costs more than Baidu's ERNIE 5.5 Flash Preview, so it makes most sense for long-context work.
