xAI's product surface — Grok judged among the AI assistants, with honest cards for Grok Build, Grok Bot, Imagine, Grokipedia, and the API.
1 of 7 lines judged in an arena · flagship: Grok in AI Assistants
Grok
JudgedChat by text or voice, analyze files, generate images and video with Imagine, and connect Gmail, Drive, Teams, Salesforce, and custom MCP tools — on the web, iOS, Android, and inside X.
Grok in X
Not yet judgedAsk Grok from the X timeline: summarize threads and replies, explain posts with real-time X context, and generate images without leaving the feed — included with X Premium.
A distribution surface of the same Grok assistant inside X (bundled with X Premium, operated with X Corp) — judged inside the grok entry; its real-time-answers capability scores there where the arena's research stories apply.
Grok Build
Not yet judgedA terminal coding agent: explore, edit, and run code with plan mode, subagents, worktrees, skills and plugin marketplaces, MCP, and headless scripting — installed with one curl.
Beta (May 2026) and shipping weekly; a genuine ai-coding contestant queued as a first-priority bring-up candidate for the next wave — deferred, not excluded.
Grok Bot
Not yet judgedNamed, persistent AI teammates on cloud computers — browser, filesystem, terminal — that take multi-step tasks, learn skills by demonstration, and run scheduled routines; bundled with Cursor plans.
docs.x.ai/grok-bot/overview.md ↗
GA August 2026, but a computer-use-teammate category with no arena yet; judging it in browser-agents or software-factory would misstate its job.
Grok Imagine
Not yet judgedGenerate and edit images and video — multi-image editing, image-to-video, cinematic aspect ratios — inside the Grok app and via the Imagine API.
docs.x.ai/developers/model-capabilities/imagine.md ↗
A capability of Grok and the API, not a standalone app; no image-generation arena exists yet (roadmap: planned).
Grokipedia
Not yet judgedBrowse and search an AI-written and AI-maintained encyclopedia.
A content destination, not a tool with user stories we rank — no encyclopedia or reference arena.
xAI API
Not yet judgedBuild on Grok models with one key: text and reasoning, image and video generation, speech-to-speech phone agents over SIP, RAG collections, and server-side tools.
Proprietary model APIs are not an arena we rank yet (roadmap: frontier-model-apis) — inference-providers ranks hosts of open models, a different job.
A judged line competes in its arena on the same stories as every rival — family membership never affects scoring. Lines without a fitting arena stay unscored until one exists. See the methodology.
