Grok

Grok is the model family from xAI, whose developer docs now brand as SpaceXAI. The models hub we fetched on 2026-08-17 marks Grok 4.6 (grok-4-6) as Latest: flagship for code and everything else, agentic tool calling, configurable reasoning, 500k context, $2.00 / $6.00 per 1M input/output tokens. Sibling APIs on the same page include Voice (from $0.05/min) and Imagine image/video (images from $0.02, video from $0.05/sec). This family page should send readers to the current flagship, not freeze on Grok 4.1 or an unverified 1M-context / AIME 95.8% claim.

For the deep 4.6 writeup see Grok 4.6. For the retired beta id see xAI: Grok Beta.

Key Features

• Current flagship grok-4.6: 500k context, configurable reasoning, agentic tools, listed at $2 / $6 per 1M tokens.
• X search and web tools: Docs still list Web Search, X Search, code execution, and MCP.
• Imagine: Image generation/editing and video generation/editing/extension on the same developer site.
• Voice: Real-time speech, TTS, STT.
• Grok Build / CLI: Separate product surface for coding, next to the API.

Use Cases

• Coding and long agents on the 500k 4.6 window.
• Live X/web questions via official search tools, not by assuming the weights contain the firehose.
• Image/video drafts on Imagine when you already have an xAI key.

Pricing

Official models hub (accessed 2026-08-17):

Consumer Grok app pricing is a different SKU (X Premium+ / SuperGrok). Recheck docs.x.ai/developers/models.

Getting Started

1. Open the models hub and confirm the Latest id.
2. Create an API key and call grok-4-6.
3. For coding, also look at Grok Build / CLI in the same docs nav.
4. Read Grok 4.6 before you copy older 4.1 numbers.

Frequently Asked Questions

Is Grok still 1M context?

The live 4.6 card we fetched says 500k tokens. Do not keep 1M without a current table.

SpaceXAI or xAI?

Developer docs use SpaceXAI in the chrome and still live at docs.x.ai. Both names appear first-party.

App vs API?

The Grok consumer app on X is not the same billable object as grok-4-6 API tokens.

Alternatives

• Grok 4.6: Full flagship entry.
• GPT-5.6 Sol: OpenAI frontier.
• Claude Opus 5: Anthropic coding flagship.

Tips

1. Quote the models hub date. xAI has been retiring older ids (docs mention a May 15 retirement).
2. Keep Imagine video rates next to Veo 3 and MiniMax H3, not inside the chat-model paragraph.
3. Fix any leftover YouTube embeds that used a full youtu.be URL as a videoId.

Conclusion

Grok is a family. In August 2026 the official Latest card is grok-4.6 at 500k and $2/$6. Start at the SpaceXAI models hub, then use the dedicated 4.6 page for depth.
