Grok 4.5 not shown in agent window model selector when set

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

In the newest iteration of the agent window model selector, Grok 4.5 receives special treatment. When selected, the name of the model is not shown in the model selector under the text input buffer, just the effort level (e.g. High) which obscures the fact that Grok is selected.

Other models are explicitly listed at the bottom of the agent window when selected.

Steps to Reproduce

  1. Select Grok 4.5 (any effort level) as the agent model – or open a new agent window, which defaults to Grok 4.5

  2. Observe that ‘Grok 4.5’ is not shown in the agent window, just the effort level (e.g. ‘High Fast’)

  3. Select a different model, such as Opus 5. Observe that the model name and effort are shown in the agent window (e.g. ‘Opus 5 High’)

Expected Behavior

All models should have parity with respect to their display in the agent window. The names and effort levels of models in use should always be listed and never be hidden.

For AI issues: which model did you use?

Grok 4.5

Does this stop you from using Cursor

No - Cursor works, but with this issue

I think this is intentional, meaning Cursor uses Grok 4.5 as the default model.

Hey there!
@IsshikiSenn is right that this is intentional. With the current model-picker layout some users are seeing, when Grok 4.5 is selected the closed control shows just the effort/speed setting (e.g. High / High Fast) rather than repeating the model name. Other models still show name + effort. Open the picker anytime to confirm it’s Grok 4.5 - that is still the selected model.

Same layout is also covered here: Cursor IDE agent window stops showing model and turns on “Fast” by default.

@mohitjain , can you elaborate on the motivation for this behavior? For the record, I’ve been using Grok 4.5 recently, and think it’s a good model, but believe that informing the user about the model they’re using is valuable.

Describe the Bug

In Cursor IDE agent window next to Agent/Plan/Debug/Multitask/Ask mode indicator, the model indicator stopped working. Instead of showing Composer/GPT/Grok etc. it shows only something like “High Fast”. It also turns on fast mode for projects, where I did not do that as a user.

Steps to Reproduce

Update Cursor IDE and open a previous project with a specific chosen agent model and fast mode disabled.

Expected Behavior

Keep project agent as selected by the user before. Show model. Do not turn on fast mode without user permission.

Exactly this is what the cursor GUI stopped to display.
