Overview
- Tool name: Grok 4.7 (grok-4.7)
- Developer: xAI (Elon Musk)
- Official website: https://x.ai
- Documentation: https://docs.x.ai
- Category: AI Models
Grok 4.7 is xAI's current flagship, available via the xAI API and the Grok apps. Three core selling points: a 500K-token context window (whole codebases and very long documents), real-time integration with the X platform (answers on time-sensitive topics are noticeably fresher than competitors'), and competitive pricing within the frontier tier.
API pricing (official, per million tokens)
- grok-4.7: $2.00 input / $6.00 output, 500K context
- Siblings: grok-4.6 ($2/$6) and grok-4.3 ($1.25/$2.50, the value tier)
- Dedicated coding variants such as grok-build-0.1 also exist
Pricing verified against xAI's official docs.x.ai pricing page (October 2026).
Lineup and ecosystem
- Grok apps: included with X Premium / SuperGrok subscriptions, with deep-search features like DeeperSearch
- API: OpenAI-compatible endpoints with tool calling and structured output
- No open weights: xAI has not released weights for any flagship; API or subscription only
Who it is for
- Real-time information tasks: news, sentiment, market moves - the X data connection is unique
- Long context: the 500K window covers most single-repo code and long-document scenarios
- Cost-sensitive frontier needs: $6 output is far below the GPT/Claude flagship tier
Limitations
- No open weights, no self-hosting
- Closed-source; evaluation coverage leans on community leaderboards (LMArena) more than rigorous third-party suites
- X / xAI API access is restricted in some regions
