Use the model picker as the source of truth
A model announcement is not a guarantee of access on every account. Check the model picker in the product you use, then confirm your region, plan and available usage. The official model documentation is dynamically rendered; we have not verified a complete current roster and do not republish the old Claude 3.5 / DeepSeek list as current.
Check access before changing your workflow
The international Free plan currently lists Auto mode only. Paid plans list access to all models, subject to the product’s availability. A model family, an exact version and an agent are different choices.
- Update the client from the official download center.
- Open the model picker and record the exact model name.
- Check your subscription and usage balance.
- Try a small task before running a long agent session.
When a model disappears
Record the client version, region, account plan and error text. Check the official documentation or support before repeatedly retrying. A missing model may reflect account eligibility, a rollout or a service issue; it does not by itself mean your installation is broken.
