Coding Plan

Summary

• Direct string replacement of model identifiers across three files with no architectural changes
• The API model identifier changes from grok-4-fast-non-reasoning to grok-latest (the official alias for Grok 4.3)
• The user-facing display name changes from "Grok 4.2" to "Grok 4.3" for consistency
• The existing @ai-sdk/xai SDK and API endpoint remain unchanged as they support the new model alias

Implementation Steps

Update XAI Model References

This phase updates all hardcoded Grok model identifiers and display names across the codebase to reflect the new Grok 4.3 release.

Task 1: Update Core Model Provider Logic

Update the model provider utility to use the new Grok 4.3 model identifier.

• In lib/utils/index.ts, change the switch case label from 'Grok 4.2' to 'Grok 4.3'
• Update both occurrences of the API model identifier from 'grok-4-fast-non-reasoning' to 'grok-latest' (lines ~44 and ~88)
• Update the fallback chain comment from "Grok" to "Grok 4.3" for clarity (line ~81)
• Update error and warning message strings that reference "Grok 4.2" to "Grok 4.3" (lines ~46, ~50)

Task 2: Update UI Model Selection Options

Update the settings UI to display the new model name and appropriate description.

• In components/settings/components/model-selection-form.tsx, update the model entry in the models array:
  • Change id from "Grok 4.2" to "Grok 4.3"
  • Change name from "Grok 4.2" to "Grok 4.3"
  • Update the description text to reflect Grok 4.3 (e.g., "The latest from xAI featuring Grok 4.3...")
  • Consider updating the badge from "New" to "Updated" or keeping it as "New" to highlight the upgrade

Task 3: Update Default Settings Value

Ensure the default model selection matches the new model identifier.

• In components/settings/components/settings.tsx, update defaultValues.selectedModel from "Grok 4.2" to "Grok 4.3"

architectural changes.

**`lib/utils/index.ts`**
- Change the switch case label from `'Grok 4.2'` to `'Grok 4.3'`
- Update both occurrences of the API model identifier from
`'grok-4-fast-non-reasoning'` to `'grok-latest'` (lines ~44 and ~88)
- Update the fallback chain comment from "Grok" to "Grok 4.3" for clarity (line

- Update error and warning message strings that reference "Grok 4.2" to "Grok
4.3" (lines ~46, ~50)

**`components/settings/components/model-selection-form.tsx`**
- In the `models` array, update the Grok model entry:
  - Change `id` from `"Grok 4.2"` to `"Grok 4.3"`
  - Change `name` from `"Grok 4.2"` to `"Grok 4.3"`
- Update the `description` text to reflect Grok 4.3 (e.g., "The latest from xAI
featuring Grok 4.3...")
- Consider updating the `badge` from `"New"` to `"Updated"` or keeping it as
`"New"` to highlight the upgrade

**`components/settings/components/settings.tsx`**
- Update `defaultValues.selectedModel` from `"Grok 4.2"` to `"Grok 4.3"`

Research

The XAI/Grok model integration is centralized across three files: lib/utils/index.ts handles the core model provider logic including SDK initialization and API model identifier usage; components/settings/components/model-selection-form.tsx defines the user-facing model options in the settings UI; and components/settings/components/settings.tsx sets the default selected model. The application uses the @ai-sdk/xai SDK to communicate with the xAI API at https://api.x.ai/v1. All model identifier strings are hardcoded and require manual updates when changing versions.
