It was the first Grok model available for commercial API use at scale. ## At a Glance **Where Grok-2 leads** - Native image generation via Aurora — text-to-image without a separate API call - Real-time X (Twitter) knowledge, the defining xAI differentiator - $2/$10 pricing — competitive with GPT-4o at launch - Strong multilingual performance including French, German, Spanish, and Japanese - Enterprise API with structured outputs, function calling, and system prompts **Where it lags** - 128K context (vs 200K+ for Claude and Gemini) - SWE-bench Verified below the 2025–2026 frontier; superseded by Grok-3 and Grok-4 - Image generation via Aurora is a separate model — not natively integrated reasoning with generation **Best for:** X-integrated applications, content generation with image output, and teams needing real-time social data alongside LLM capabilities. ## What Grok-2 Is Grok-2 was released at xAI's enterprise API launch in August 2024. It represented a major capability leap from Grok-1.5 — significantly better on GPQA (scientists-level questions), math, and coding, with the addition of vision understanding. The Aurora image generation integration made it the first commercial LLM API to offer combined text reasoning + image generation in a single provider relationship. Grok-2 Mini launched simultaneously as a smaller, faster, cheaper variant for high-volume use cases where the full Grok-2 would be cost-prohibitive. ## Specifications | Field | Value | |---|---| | Organization | xAI | | Context window | 128,000 tokens | | License | Proprietary | | Release date | August 13, 2024 | | Knowledge cutoff | June 2024 | | Modality | Multimodal (text + vision input; text + image output via Aurora) | | Data access | Real-time X (Twitter) | ## Pricing | | Input (per 1M tokens) | Output (per 1M tokens) | |---|---|---| | xAI API | $2.00 | $10.00 | Source: [xAI API pricing](https://x.ai/api). ## Public Benchmark Scores | Benchmark | Score | Source | Date | |---|---|---|---| | GPQA | 56.0% | [xAI — Grok-2](https://x.ai/blog/grok-2) | 2024-08 | | MATH | 76.1% | [xAI — Grok-2](https://x.ai/blog/grok-2) | 2024-08 | | HumanEval | 92.7% | [xAI — Grok-2](https://x.ai/blog/grok-2) | 2024-08 | | MMLU | 87.5% | [xAI — Grok-2](https://x.ai/blog/grok-2) | 2024-08 | *Scores reported by xAI.
