Does VerticalAPI surface Grok's X-data feature?

Grok's real-time X data access is enabled via xAI's native parameters; VerticalAPI passes them through unchanged.

Is the xAI API OpenAI-compatible already?

xAI's API is broadly OpenAI-compatible at the wire format. VerticalAPI normalizes edge cases (tool_choice, response_format) so your code is portable across all providers.

Frequently asked questions

What is xAI and what models do they offer?

xAI is Elon Musk's AI company, creator of the Grok model family. The 2026 lineup is Grok-3 (frontier reasoning with chain-of-thought), Grok-2 (general-purpose multimodal), Grok-2 mini (cheap/fast) and Aurora for image generation. Grok models have native access to X (Twitter) data via the platform's real-time feed and support function calling, vision input and a 128K context.

How much does xAI cost in 2026?

Grok-3 is roughly $3 per 1M input tokens and $15 per 1M output. Grok-2 is around $2/$10. Grok-2 mini is approximately $0.30/$0.50. Image generation (Aurora) is per-image priced. xAI offers free tier credits for new accounts and X Premium+ subscribers get expanded quotas. Via VerticalAPI BYOK you pay xAI directly with zero token markup.

How do I use xAI via VerticalAPI BYOK?

Create a key at console.x.ai, paste it into VerticalAPI, then point the OpenAI SDK at https://api.verticalapi.com/v1. xAI is OpenAI-compatible, so VerticalAPI passes through with added logging and fallback routing. Function calling, vision input and streaming are preserved. Billing remains on your xAI invoice.

What is xAI best for compared to alternatives?

Grok wins for any task that benefits from real-time X/Twitter context (social monitoring, trending news, public-figure intelligence). Grok-3 is a credible alternative frontier model with competitive benchmarks. Compared to GPT-4o it has fewer ecosystem integrations but a unique live-X data advantage. Not a fit for enterprise compliance-heavy workloads where vendor maturity matters.

Where is xAI hosted / data privacy?

xAI runs on its Colossus GPU cluster (Memphis, TN) and partner clouds. API data is not used to train models on the paid tier. Free tier may opt into training. Enterprise terms are evolving in 2026. Via VerticalAPI BYOK your xAI contract terms are preserved.

Limitations and trade-offs

Smaller developer ecosystem and fewer third-party tools than OpenAI or Anthropic.
Enterprise compliance certifications (SOC 2, HIPAA, EU residency) are less mature.
Output pricing ($15/1M on Grok-3) is at parity with frontier models without clear quality lead on all benchmarks.
Brand/political associations with X and Elon Musk may be a procurement blocker for some enterprises.
Limited geographic deployment — primarily US-hosted as of 2026.

Where xAI is heading

Grok-4 generation expected with deeper reasoning and multimodal.
Expanded Aurora image and video generation capabilities.
Tighter integration with X platform for live social intelligence APIs.
Growth of enterprise tier with SOC 2 and regional deployment.

All supported LLM providers

Same endpoint, same SDK — just change the model and the BYOK header.
