Summary

Adds xAI's Grok 4.6 (grok-4.6) to the built-in Grok catalog so it can be selected out of the box. Reuses the existing OpenAI-compatible xAI endpoint and openai thinking adapter; the only catalog delta vs Grok 4.5 is the documented xhigh reasoning effort.

Related Issues

Closes #1112

Changes

  • Add grok-4.6 first in the Grok provider list (500k context / 500k output, vision, tools)
  • Map thinking as non-toggleable reasoning_effort low / medium / high / xhigh (default high) via a dedicated grok46Effort capability — disabling is coerced to low, matching other always-on effort models
  • Cover catalog placement, metadata, and xhigh request injection in unit tests
  • Update supported-model docs in all locales (also lists Grok 4.5 / 4.3 / Build 0.1 that were already in the catalog) and add a GROK_MODELS example

Type of Change

  • Bug fix (non-breaking change that fixes an issue)
  • New feature (non-breaking change that adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to change)
  • Documentation update
  • Refactoring (no functional changes)
  • CI/CD or build changes

Verification

Steps to reproduce / test

  1. Open the model picker and select the Grok provider — Grok 4.6 is listed first
  2. Thinking control offers low / medium / high / xhigh, default high, with no disable/none option
  3. npx vitest run tests/ai/openai-provider.test.ts tests/ai/thinking-config.test.ts tests/ai/model-metadata.test.ts

What you personally verified

  • Targeted tests: 74 passed (RED first: picker still started at grok-4.5 and xhigh was not injected)
  • Full tests/ai suite: 129 passed
  • ESLint clean on the changed TypeScript files
  • Not verified: a live xAI API call with grok-4.6 / xhigh (no key in this environment)

Evidence

  • CI passes (pnpm check && pnpm lint && npx tsc --noEmit)
  • Manually tested locally
  • Screenshots / recordings attached (if UI changes)

The Grok picker still topped out at 4.5, so the new flagship ID was not selectable with its documented xhigh reasoning effort.

fix(docs): stop the docs Next app from loading app instrumentation
d62b583 
Next 16 discovers the repo-root instrumentation.ts from packages/docs, then fails because that file imports app persistence modules. Give the standalone docs app a no-op register() so the Grok catalog docs can build.
