NEW Grok 4 Coder (Sonic): Blazing Fast + Powerful Fully FREE Stealth Model! (Tested)

Key Concepts

• Sonic: A new, free coding model from Grock (likely).
• Context Window: 256K, suitable for real-world coding.
• Speed: The primary selling point of the Sonic model.
• Klein & Root Code: IDEs where Sonic can be tested.
• Vectal: An AI agent for task automation.
• Reasoning Capabilities: Built-in reasoning for code generation.
• SVG Generation: Creating images using code.

Sonic: A New Coding Model

The video introduces Sonic, a new coding model that has been officially released. It's designed specifically for coding and is free to use in apps like Klein, Cursor, Root Code, and others. The model is noted for its speed and solid performance, with some comparing it to Grok-4 coder.

• Origin: The Sonic model is likely from Grock, evidenced by the function call name "XCI" found within the fig files.
• Context Window: It features a 256K context window, which is considered decent for real-world coding applications.
• Performance: While not the best model overall, its speed and output capabilities are impressive. It was able to output 300 lines of HTML code in a single shot, including a video showcasing a full webpage with various components and games.
• Example: A developer on Twitter, Echohhive, used Sonic to create a Minecraft clone, writing 10,000 lines of code. The model generated a step-by-step to-do list and outputted the clone with terrain generation and blocks.

Vectal: An AI Agent for Task Automation

The video then transitions to Vectal, an AI agent designed to automate tasks.

• Functionality: Vectal allows users to input a project name and description, such as setting up a Node.js REST API.
• System Prompt Generation: It can generate a system prompt optimized for the task.
• Model Integration: Vectal allows the use of state-of-the-art models.
• Task Breakdown: Vectal breaks down tasks into subtasks. For example, setting up a Node.js REST API was divided into five subtasks.
• Idea Box: Vectal includes an idea box for brainstorming.
• Web Search: The chat agent uses built-in Perplexity Pro capabilities for web searches.
• MCPS: Users can leverage MCPS for extra tools.
• Offer: A special offer is provided for viewers to try Vectal, including unlimited GBT5 and 30 days of Vectal Pro free with the code "world."

Setting Up and Testing Sonic

The video demonstrates how to set up and test the Sonic model within Klein and Root Code.

• Availability: Access to Sonic within these apps is temporary (72 hours) for testing purposes.
• VS Code Integration: Users can use VS Code with extensions like Klein or Root Code.
• Installation: The video guides users on installing the Klein or Root Code extension in VS Code.
• Connection: Users can connect to the Root Code cloud to access the Sonic model or select Sonic within Klein's settings after signing up for a free account.
• Test Case 1: AI SaaS Landing Page: The model was asked to create an AI SaaS landing page. It generated the code quickly, creating the file and generating the content. The resulting landing page was functional but not as visually appealing as those generated by other models.
• Test Case 2: SVG Butterfly Generation: The model was tasked with generating a butterfly using SVG code. The result was a symmetrical butterfly with vibrant colors.
• Test Case 3: Minecraft Clone: The model was asked to create a Minecraft clone. It rapidly generated the code, creating the core components of the game, including block placement. However, the resulting clone was laggy.
• Test Case 4: 3D Star Animated Simulation: The model was requested to make a 3D star animated simulation. It was fast and produced a good output.

Performance and Observations

The video provides observations on Sonic's performance.

• Speed: The model's speed is its primary selling point.
• Reasoning: It has built-in reasoning capabilities, which contribute to its performance.
• Error Rate: The model exhibited approximately zero errors during the tests.
• Potential Cost: The reasoning capabilities suggest it could be an expensive model upon full release.

Conclusion

The Sonic model is a fast and capable coding model, particularly strong in speed and reasoning. While not perfect, it offers a valuable tool for developers, especially given its current free availability. The video encourages viewers to try it out within the limited 72-hour window. The video also highlights Vectal as a tool to help developers automate tasks.
