+Fix Vercel AI Gateway Grok model identifiers: the gateway moved xAI models from
+the `xai/` to the `spacexai/` namespace, so `VercelModel.Grok_*` now resolve
+again. Add `VercelModel.Grok_4_7`, `GPT_6_Sol`, `GPT_6_Luna`, and
+`Gemini_3_8_Flash`, with matching CLI picker options.

 ## Unreleased
 
+- Add Claude Opus 5.5 model constants for Claude Code, OpenRouter, Vercel AI
+  Gateway, OpenCode/Zen, and Cursor, mirroring `@upstash/box`.
+- Fix Vercel AI Gateway Grok identifiers: the gateway moved xAI models from the
+  `xai/` to the `spacexai/` namespace, so `VercelModel.GROK_*` now resolve again.
+  Add `VercelModel.GROK_4_7`, `GPT_6_SOL`, `GPT_6_LUNA`, and `GEMINI_3_8_FLASH`.
+- Add GPT-6 Sol and GPT-6 Luna to `OpenAICodex`, `OpenRouterModel`, and
+  `OpenCodeModel`.
 - Fix `delete_boxes(box_ids=[])` deleting every box on the account. The API read
   an empty id list as "no filter". `delete_boxes` and `delete_snapshots` now raise
   `BoxError` before any request is made when the list is empty or contains a
