[Bug]: Model extremely slow on terminal-bench + fails sanity check

[Vedang12345]

Bug Description

When running grok-cli against terminal-bench, the model takes an unusually long time to start completing tasks and fails even the basic hello-world sanity check.

Steps to reproduce

1. Install and set up terminal-bench as per the README.
2. run command : tb run -a grok-cli -m grok-4-latest -d terminal-bench-core==0.1.1
3. Observe that progress is extremely slow — around 6% in 1 hour — and the hello-world task does not pass.

Expected Behavior:

The model should quickly start producing completions for tasks.

The hello-world task should pass as a basic sanity check.

Actual Behavior:

The run hangs for long periods between actions.

Progress is very slow (6% in ~1hr).

This worked before you guys fixed the previous hanging issue I came with.

@Vedang12345 I'm trying to figure out why it doesn't work, running the command:

grok -m grok-code-fast-1 -p "Create a file called hello.txt in the current directory. Write 'Hello, world!' to it." works in my terminal and does the correct thing, seems to fail on terminal bench though. Any ideas why this could be?

in Terminal:

grok -m grok-code-fast-1 -p "Create a file called hello.txt in the current directory. Write 'Hello, world!' to it."
