Grok 4.5 becomes the default xAI and SuperGrok model

What changed

Roder 0.1.10 updates the xAI-backed provider catalog. The direct xai provider and the SuperGrok OAuth provider now expose grok-4.5 as their default model.

The new model entry carries a 500k context window and defaults to high reasoning. It also keeps the supported reasoning choices explicit: low, medium, and high. Existing Grok 4.3, Grok 4.20, SuperGrok Build, and SuperGrok Composer entries remain selectable, so existing pinned workflows do not need to move immediately.

Why it matters

• xAI API-key users and SuperGrok OAuth users now get the same current default model in Roder.
• Long-context coding sessions can use Grok 4.5’s 500k context window without custom catalog overrides.
• Reasoning behavior is predictable. New sessions start at high reasoning, while users can still lower reasoning for faster or cheaper turns when the provider path supports it.
• Existing Grok model selections remain available, which keeps saved configs, scripts, and comparisons stable while the default advances.

Using it

For the direct xAI API-key path, configure the xAI credential and select the provider normally:

export XAI_API_KEY="..."
RODER_PROVIDER=xai RODER_MODEL=grok-4.5 cargo run -p roder-cli

For SuperGrok, keep using the OAuth-backed provider flow:

roder auth login supergrok
RODER_PROVIDER=supergrok RODER_MODEL=grok-4.5 cargo run -p roder-cli

You can omit RODER_MODEL when you want the provider default. Pin one of the older Grok entries only when a workflow depends on that exact model behavior.
