The Chinese start-up has introduced only a few incremental updates in recent months, while competitors have released new models

DeepSeek announced on Tuesday the release of the V3.1 model in a brief message to one of its WeChat user groups. The update expands the context window to 128k, allowing the model to hold more information – equivalent to a roughly 300-page book – during user interactions.

The company did not announce the update on its public social media channels, including its X account.
