OpenRouter has listed Baidu’s ERNIE-Light-DT-1.0, a model the page says is based on open-source GLM models and incorporates research findings from Baidu Search’s Lightning large model. The listing gives it a context window of 1,024,000 tokens.
The page also names Baidu Sparse Attention, or BSA, as a feature. It does not provide pricing or further technical details about BSA in the available description.
Why it matters
Developers using OpenRouter can see a listed context window large enough for very long inputs, though the page does not explain pricing or how well the model handles them.
