# v0.9.40, build 215 (2025-04-xx xx:xx UTC) - Added support for the announced OpenAI `o4` models. We hope that these `o4` models will be usable by the well-known chat completion API instead of the new responses API, though. AI Studio cannot use the new responses API right now. - Added Alibaba Cloud as a new provider. - Improved the provider selection by showing the name of the provider in the provider selection instead of its identifier. - Fixed an issue where OpenAI `o3` models were not shown in the model selection.
