State-of-the-art video generation across quality, cost, and latency.

We're excited to unveil the Grok Imagine API, a unified bundle of powerful APIs designed for end-to-end creative workflows. Grok Imagine is our most powerful video-audio generative model yet. Bring an image to life, start from a simple text prompt, or even refine a complex cinematic sequence.

Video generation

Grok Imagine has best-in-class instruction following capabilities.

Video editing

Restyle scenes, add/remove objects, and control motion.

Performance and Benchmarks

We engineered these models to deliver high-quality, native video-audio generation on par with today's top providers, while also optimizing latency, concurrency, and cost—refined through multiple rounds of close partner feedback. One message came through consistently: quality alone is not enough if latency and cost make iteration painful. By improving speed and economics, we enable developers, creative teams, and enterprise workflows to explore multiple directions in parallel—converging faster through rapid, cost-effective experimentation.

What our partners are saying

The Grok Imagine API is available on our partner platforms, alongside our own API.

"We are thrilled to partner with xAI. Grok Imagine API delivers outstanding video quality with native audio video generation, combining photorealistic realism, strong creative style, and an impressive level of control."

"The ComfyUI team gravitates strongly toward retro anime and cyberpunk aesthetics, and Grok performs exceptionally well in both text-to-image and image-to-video generation for these styles."

"Grok is awesome because it helps bring the craziest ideas to life. At a video level grok brings visuals to life with accuracy and fluidity to actions that are prompted as well as to create visuals that are creatively restrictive to make using other models.The Addition of sound and dialogue further help in bringing visuals to life."

"Imagine API is great at fast, high-quality visual ideation. It’s particularly strong at capturing scene-level style, mood, and physical realism, making it a great fit for early creative exploration and rapid iteration!"

"We've been integrating Grok into our Video Agent at HeyGen. With Grok's latest video model, you can just prompt edits directly for quick tweaks, empowering our users to iterate on clips in minutes instead of completely leaving it to luck. Excited to see more capabilities unlock from Grok."

State-of-the-art RAG system built directly into our API.

Today, we're excited to announce Collections API. With Collections, you can upload and search through entire datasets. From PDFs and Excel sheets to entire codebases, you can upload your files into a knowledge base that supports precise and fast search. This allows developers to build RAG applications without the headache of managing indexing and retrieval infrastructure.

To help you get started, we're making file indexing and storage free for the first week*, with retrieval priced at a flat rate of $2.50 per 1,000 searches.

Indexing

• Powerful document understanding: We use OCR and layout-aware parsing to extract text while preserving structure such as the layout of a PDF, hierarchy of an Excel table, or the syntax of code.
• Smart file management: Easily upload, update, and download files. And when a file changes, our system efficiently reindexes it to ensure your collection is never stale.
• Broad format support: Collections supports a wide range of file types. (see full list)

Retrieval

Choose the retrieval method that best fits your use case:

• Semantic search: To search using the meaning and intent behind a query.
• Keyword search: For precise term matching.
• Hybrid search: For the highest accuracy, combine keyword and semantic search. We support both a dedicated reranker model and reciprocal rank fusion.

Benchmark Results

Our Collections API delivers state-of-the-art retrieval performance, matching or outperforming leading models in real-world RAG tasks across finance, legal, and coding domains.

These fields are especially challenging due to their long, dense documents. To avoid hallucinations and deliver reliable answers, models must retrieve the exact passages and reason over them accurately.

Accuracy* (Higher is better)

Task | xAI Grok 4.1 Fast | Google Gemini Pro 3 | OpenAI GPT 5.1
Finance Tabular and numerical questions | 93.0 | 85.9 | 84.7
Legal Complex reasoning over multiple chunks | 73.9 | 74.5 | 71.2
Coding Code understanding and large file systems | 86 | 85 | 81

*Internal source.

Financial Analysis

Extracting tabular and numerical data from files can be challenging with semantic search alone. Hybrid search enables you to accurately retrieve this data from documents such as SEC filings*, allowing the model to precisely reference information.

Legal Analysis (LegalBench)

The LegalBench dataset tests retrieval and reasoning over nuanced legal language and complex cross-references, consisting of 128 challenging question-answer pairs drawn from an extensive corpus of authentic commercial contracts across multiple datasets.

Codebase (DeepCodeBench)

Code understanding is crucial for applications such as code summarization and generation. We use the DeepCodeBench dataset to comprehensively benchmark for this. It features a diverse set of tasks drawn from real-world open-source repositories, API usage, and complex algorithmic problems.

Data Privacy

We do not use user data stored on Collections for model training purposes, unless the user has given consent.

Start Building

Code examples and instructions are provided for creating and searching collections, using collections in chat, and direct API usage.

*You may be charged after the free trial period. We will follow up with more information.
