  * IMPORTANT: Model names MUST use `antigravity-` prefix for stability.
  *
- * The opencode-antigravity-auth plugin supports two naming conventions:
- * - `antigravity-gemini-3-pro-high` (RECOMMENDED, explicit Antigravity quota routing)
- * - `gemini-3-pro-high` (LEGACY, backward compatible but may break in future)
+ * Since opencode-antigravity-auth v1.3.0, models use a variant system:
+ * - `antigravity-gemini-3-pro` with variants: low, high
+ * - `antigravity-gemini-3-flash` with variants: minimal, low, medium, high
  *
- * Legacy names rely on Gemini CLI using `-preview` suffix for disambiguation.
- * If Google removes `-preview`, legacy names may route to wrong quota.
+ * Legacy tier-suffixed names (e.g., `antigravity-gemini-3-pro-high`) still work
+ * but variants are the recommended approach.
  *
