• 41 xAI models returned by the API were not created because the Models API does not provide enough authoritative metadata for the catalog, especially output token limits and some feature/capability flags. Existing models are still updated from API-authoritative fields.
• Skipped remote IDs: grok-imagine-video-1.5, grok-4.20-non-reasoning, grok-4.20-non-reasoning-latest, grok-4.20-beta-non-reasoning, grok-4.20-beta-latest-non-reasoning, grok-4.20-experimental-beta-0304-non-reasoning, grok-4.20-experimental-beta-non-reasoning-latest, grok-4.20-beta-0309-non-reasoning, grok-4.20-non-reasoning-gv2, grok-4.20-reasoning-latest, grok-4.20, grok-4.20-reasoning, grok-4.20-0309, grok-4.20-beta-0309-reasoning, grok-4.20-beta, grok-4.20-beta-0309, grok-4.20-beta-latest, grok-4.20-beta-latest-reasoning, grok-4.20-beta-reasoning, grok-4.20-experimental-beta-0304-reasoning, grok-4.20-experimental-beta-0304, grok-4.20-experimental-beta-reasoning-latest, grok-4.20-experimental-beta-latest, grok-4.20-reasoning-gv2, grok-4.20-multi-agent, grok-4.20-multi-agent-latest, grok-4.20-multi-agent-beta-latest, grok-4.20-multi-agent-experimental-beta-0304, grok-4.20-multi-agent-experimental-beta-latest, grok-4.20-multi-agent-beta-0309, grok-4.3-latest, grok-latest, grok-code-fast-1, grok-code-fast, grok-code-fast-1-0825, grok-imagine-image-2026-03-02, grok-imagine-image-quality-20260403, grok-imagine-image-quality-latest, grok-imagine-image-pro, grok-imagine-video-1.5-preview, grok-imagine-video-1.5-2026-05-30
