Gorilla: Bridging LLMs and the Real World

Some time ago, I stumbled upon the Gorilla project, and it immediately reminded me of platforms like make.com and n8n, which also leverage the power of APIs by incorporating them into workflows. However, Gorilla felt different, slightly more nuanced in its approach. It's not just about chaining together pre-defined API calls; it's about enabling Large Language Models (LLMs) to dynamically interact with a vast ecosystem of software tools and services. LLMs, after all, don't exist in a vacuum. Their true potential is unlocked when they are integrated into the real world, and that's precisely what Gorilla aims to do. Imagine a world where you could describe a task in plain English and have an LLM not only understand your request but also execute the necessary commands to make it happen. That’s the vision Gorilla is bringing to life, connecting LLMs with a massive collection of APIs.

Gorilla: The Bridge Between LLMs and the Real World

Imagine describing a task in plain English – like "list all my cloud servers" or "get the weather in London" – and having an LLM not just understand your request but also execute the necessary commands to make it happen. That's the power Gorilla unlocks. It's built on a robust LLM fine-tuned to understand and translate natural language into precise API calls, supporting over 1,600 APIs across various domains like cloud computing (AWS, GCP, Azure), development tools (GitHub, Conda), and even system utilities (Curl, Sed).

Key Components of the Gorilla Ecosystem

The Gorilla ecosystem comprises several key elements that work together to deliver this powerful functionality:

Gorilla Core LLM: The brain of the operation, this LLM is fine-tuned on models like MPT and Falcon and is specifically trained to reduce API "hallucinations" (generating incorrect or non-existent API calls). It's also open-source (Apache 2.0 licensed), allowing for commercial use and community contributions.
Gorilla OpenFunctions: This is where Gorilla truly shines. OpenFunctions v2, the latest version, is a state-of-the-art open-source function calling system on par with offerings like GPT-4. It supports complex scenarios like choosing between multiple functions, calling the same function multiple times in parallel, and even distinguishing between regular chat and function call requests. It also boasts broad language support, including Python, Java, and JavaScript, making it incredibly versatile.
Berkeley Function Calling Leaderboard: This platform provides a comprehensive evaluation framework for function calling, fostering community contributions and ensuring continuous performance tracking and improvement.
API Zoo: The fuel that powers Gorilla, the API Zoo is the largest collection of community-contributed APIs, curated and ready for training. It’s a constantly growing library, ensuring Gorilla stays up-to-date with the latest tools and services.

Three Ways to Tame the Gorilla

Gorilla offers multiple ways to leverage its power, catering to different needs and levels of technical expertise:

Gorilla CLI: The Simplest Path

Want to quickly try out Gorilla? The Command Line Interface (CLI) is your friend. Install it with a simple

pip install gorilla-cli and you're ready to go. Just type gorilla "your command in natural language" and Gorilla will suggest possible API commands, letting you choose the one that fits best. For example, you could say gorilla "generate 100 random characters into a file called test.txt" and Gorilla would suggest the appropriate command-line tools to achieve this. The CLI handles everything from processing your input, selecting the best command, executing it with your approval, and even sending feedback to improve the model.
Hosted Gorilla OpenFunctions: For Developers

If you're a developer looking to integrate Gorilla directly into your applications, the hosted OpenFunctions service offers a seamless experience. Compatible with OpenAI's API, you can use familiar Python code to send requests and receive structured responses, including both human-readable text and machine-parsable JSON. This allows you to easily incorporate powerful function-calling capabilities into your applications. For example, you can ask Gorilla "What's the weather in Boston and San Francisco?" and define a get_current_weather function. Gorilla will then return the appropriate function calls with the correct arguments.
Running Gorilla Locally: Full Control

For maximum control and customization, you can run Gorilla locally. This option provides a structured prompt format and response formatting tools, allowing you to fine-tune the model's behavior and integrate it into your own infrastructure. You'll need to install some dependencies, but this approach gives you complete ownership over the entire process.

Privacy and Security: A Top Priority

Gorilla is designed with privacy and security in mind. It only executes commands with your explicit approval, and it doesn't collect the output (stdout) of those commands. Only the queries themselves and any errors (stderr) are used for model improvement. Furthermore, all commands are executed locally, ensuring your data stays within your control. User identification relies on either a Git email address or a randomly generated UUID stored locally, prioritizing privacy while still allowing for some degree of personalization. A history mechanism also keeps track of your interactions, but it's designed to prevent duplicates and limit the history length.

Gorilla in Action: Real-World Examples

The potential applications of Gorilla are vast. Here are a couple of examples:

Cloud Operations: Imagine simplifying your cloud management with commands like gorilla "list all my GCP instances". Gorilla would translate this into the appropriate gcloud command, saving you from remembering complex syntax and reducing the cognitive load.
Kubernetes Management: Interacting with Kubernetes can be daunting. With Gorilla, you could simply say gorilla "get the image ids of all pods running in all namespaces" and Gorilla would handle the complex kubectl commands needed to retrieve that information.

The Future of Gorilla: Even More Powerful and User-Friendly

Gorilla is a rapidly evolving project with an ambitious roadmap. Future developments include:

Enhanced Capabilities: Offline mode support, local model options, and expanded API coverage.
Integration Features: Seamless integration with OpenFunctions, custom API support, and enterprise deployment options.
User Experience: Project-specific suggestions, learning from user preferences, and customizable command sets.

Conclusion: A New Era of LLM-Powered Automation

The Gorilla ecosystem represents a significant leap forward in connecting LLMs with the practical tools and APIs that power our digital world. Whether you're a developer looking to build powerful applications, an IT professional seeking to automate tasks, or simply curious about the potential of LLMs, Gorilla offers a compelling solution that's both powerful and user-friendly. As the project continues to grow and evolve, driven by community contributions and a commitment to innovation, Gorilla is poised to redefine how we interact with computers and unlock a new era of LLM-powered automation.
