It focuses heavily on long-running agents that can work across a codebase, research problems, test their work, and keep going through complex multi-step tasks. According to xAI's evaluations, Grok 4.6 reaches frontier-level performance and matches GPT-5.6 Sol on the Artificial Analysis Intelligence Index.\n\nWhat makes it even more interesting for developers is ** Grok Build**, xAI's own terminal coding agent and TUI. Instead of relying on a third-party coding interface, xAI built a full-screen, interactive terminal experience specifically for working with its models, and Grok 4.6 now powers Grok Build directly.\n\nIn this guide, we will use Grok Build and just **four prompts** to create an end-to-end data science project that predicts how long a customer may need to wait for a coffee order.\n\n## What Is Grok Build?\n\nGrok Build is xAI's coding agent for working directly from the terminal.\n\nIt can understand your project, create and edit files, execute commands, search the web, and work through longer coding tasks. Its interactive TUI provides a full-screen, mouse-enabled coding experience, and it can also run headlessly for scripts and automation.\n\nThe biggest advantage is that **Grok 4.6 is the same model powering Grok Build**, so you get xAI's latest coding model inside a coding environment built specifically around it.\n\n## Installing Grok Build\n\nGrok Build provides prebuilt versions for Windows, macOS, Linux, and Windows Subsystem for Linux.\n\n**For macOS, Linux, or WSL,** open a terminal and run:\n\n```\ncurl -fsSL https://x.ai/cli/install.sh | bash\n```\n\n**For Windows PowerShell**, open PowerShell and run:\n\n```\nirm https://x.ai/cli/install.ps1 | iex\n```\n\nConfirm that Grok Build was installed:\n\n```\ngrok --version\n\n>> grok 1.0.4 (d846eb93d9)\n```\n\n## Creating the Project Folder\n\nStart by creating a clean project folder and launching Grok Build inside it so the agent can build everything in one workspace.\n\nCreate an empty folder for the project:\n\n```\nmkdir coffee-wait-time-project\ncd coffee-wait-time-project\n```\n\nStart Grok Build inside the folder:\n\n```\ngrok\n```\n\nGrok Build opens its interactive terminal interface. On the first launch, it normally opens a browser so you can sign in.\n\n## Prompt 1: Generating and Exploring the Dataset\n\nFor the first step, we asked Grok Build to generate a realistic dataset, clean it, explore the data, and create useful visualizations.\n\n**Prompt:**\n\nCreate a beginner-friendly end-to-end data science project by generating 3,000 realistic coffee shop orders with customer waiting time as the target, save the dataset in data/coffee_shop_orders.csv, perform data cleaning and exploratory analysis, and save useful visualizations inside reports/figures.\n\nGrok Build first reviewed the project folder and then started creating the dataset and analysis workflow.\n\nWithin a few minutes, it generated the raw dataset and a **cleaned dataset with 2,986 rows**. It also handled missing values and removed 14 extreme wait-time outliers.\n\nThe initial analysis already gave us some useful insights. The average wait time was around **10.5 minutes**, rush hour added roughly **3.3 minutes**, and staff load had the strongest relationship with wait time, with a correlation of **0.68**.\n\nIt also created a baseline Random Forest model with an **MAE of 1.63 minutes and R² of 0.85**.\n\n## Prompt 2: Training and Evaluating the Models\n\nIn this step, we asked Grok Build to prepare the data pipeline, train multiple models, compare them, and save the best full pipeline for reuse.\n\n**Prompt:**\n\nPrepare the coffee shop data using a reusable scikit-learn preprocessing pipeline, train Linear Regression, Random Forest, and Gradient Boosting models, compare them using MAE, RMSE, and R², evaluate the best model with charts and test predictions, and save the complete winning pipeline as models/coffee_wait_time_pipeline.joblib.\n\nGrok Build continued from the cleaned dataset and built a reusable ** scikit-learn** preprocessing and training pipeline.\n\nDuring the process, I hit the **free usage limit**, so I upgraded my plan and then typed \"continue\". Grok Build picked up exactly where it had stopped and completed the model training and evaluation.\n\nIt trained **Linear Regression, Random Forest, and Gradient Boosting**, then compared them on the hold-out test set of **598 orders**.\n\nThe results showed that **Gradient Boosting** performed best, with an **MAE of 1.101**, **RMSE of 1.408**, and **R² of 0.934**. Linear Regression also performed well, while Random Forest came in third.\n\nAfter that, Grok Build saved the winning pipeline as `models/coffee_wait_time_pipeline.joblib`\n\n, giving us a ready-to-use model for the next stages of the project.\n\n## Prompt 3: Building the FastAPI Application\n\nIn this step, we asked Grok Build to turn the trained model into a simple ** FastAPI** application with clean endpoints and input validation.\n\n**Prompt:**\n\nCreate a beginner-friendly FastAPI application in main.py that loads models/coffee_wait_time_pipeline.joblib, provides root, health-check, and prediction endpoints, validates coffee order inputs with Pydantic, returns the estimated waiting time and a short explanation, handles errors clearly, and includes examples in the automatic API documentation.\n\nGrok Build created a FastAPI app that loads the saved pipeline at startup and exposes three endpoints:\n\n**GET /** for service information and example usage**GET /health** to confirm the model is loaded**POST /predict** to estimate the coffee order wait time and return a short plain-English explanation\n\nIt also added ** Pydantic** validation, so invalid inputs are handled clearly with structured error messages.\n\nBefore deploying, I asked Grok Build to **test all of the API endpoints itself**. It started the server, sent test requests, checked the responses, and confirmed that the prediction and validation endpoints were working correctly.\n\n## Prompt 4: Deploying to FastAPI Cloud\n\nIn this step, we asked Grok Build to prepare the project for deployment, deploy it to ** FastAPI Cloud**, and test the live API.\n\n**Prompt:**\n\nPrepare this project for FastAPI Cloud by confirming fastapi dev works, configuring the application entry point if needed, ensuring the saved model and required files are included, running fastapi deploy, pausing only if browser authentication is required, testing the live root, health, prediction, and docs endpoints, fixing deployment errors, and showing me the final public API URL.\n\nDuring deployment, FastAPI Cloud asked me to sign in through the browser. Once I authenticated, Grok Build continued the deployment automatically.\n\nAfter the deployment finished, it gave me the public Swagger documentation URL and a ready-to-use curl command for testing the live prediction endpoint.\n\nAfter deployment, Grok Build also gave me a ready-to-use `curl`\n\nrequest to test the live `/predict`\n\nendpoint:\n\n```\ncurl -X POST https://coffee-wait-time.fastapicloud.dev/predict \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"order_date\":\"2025-03-13\",\"hour_of_day\":8,\"item_name\":\"Latte\",\"item_size\":\"Medium\",\"quantity\":1,\"customization_count\":2,\"order_channel\":\"In-Store\",\"payment_method\":\"Card\",\"queue_length\":5,\"num_baristas\":2,\"weather\":\"Rainy\",\"is_member\":1,\"order_total\":5.50}'\n```\n\n**The live API returned:**\n\n```\n{\n  \"predicted_wait_time_minutes\": 13.06,\n  \"explanation\": \"Estimated wait time is about 13.1 minutes, mainly due to a moderate queue (5 people), rush-hour timing.\",\n  \"model_name\": \"Gradient Boosting\",\n  \"model_metrics\": {\n    \"MAE\": 1.101,\n    \"RMSE\": 1.408,\n    \"R2\": 0.934\n  }\n}\n```\n\nThis confirmed that the **deployed model, preprocessing pipeline, and FastAPI prediction endpoint were all working correctly in production**. The API predicted a wait time of about **13.1 minutes** and also returned a simple explanation along with the model performance metrics.\n\nI also tested the prediction directly through the **live Swagger UI**, which returned the expected prediction along with the model metrics and explanation.\n\nFinally, Grok Build organized the complete project and updated the **README** with the project workflow, model results, live API link, and instructions for running and deploying the application. This makes the entire project easy to understand and reproduce.\n\n## Final Thoughts\n\nAfter using Grok Build for this project, I came away genuinely impressed. It handled the full workflow well — from generating and cleaning the data to training models, building the API, testing it, fixing issues, and deploying everything. With **Grok 4.6**, it now feels much more capable and polished for serious coding work.\n\nFor me, **Grok Build is now on par with Claude Code** for many practical development tasks. The biggest improvement is how well the new model handles longer, multi-step workflows without constantly needing guidance. If xAI keeps improving the model and the terminal experience, Grok Build could easily become one of the best AI coding agents available.\n\n(\n\n[Abid Ali Awan](https://abid.work)\n\n[@1abidaliawan](https://www.linkedin.com/in/1abidaliawan)) is a certified data scientist professional who loves building machine learning models.
