Building APIs for AI

Introduction

Welcome to this week's Tech Talk, where we explore "AI Power for Any Application: An API-Based Approach to AI." I am Nathan Melis, the head of engineering for Modsy, an artificial intelligence platform that aims to bridge what we call the AI Valley of Death. This term refers to the challenging process of moving AI/ML models from the laboratory to production in a secure and scalable manner.

We meet every Thursday at 12:30 PM Eastern Standard Time, and we cover a wide range of topics. Recordings are posted to the archive channel, and we welcome your suggestions or requests for future talks in the Tech Talks Ideas channel. Next week, we'll provide an overview of the Chassis.ml service, so make sure not to miss it!

Today, I would like to share our experiences in building an API-driven AI product, highlighting high-level takeaways that can be beneficial when developing your own APIs, especially for emerging technologies.

Understanding the Diverse Personas

When developing AI-driven APIs, we need to consider the varied personas involved in the process:

1. Data Scientists: Experts in mathematics and algorithms, they may lack programming and cloud architecture experience. They might struggle with hardware allocation for efficient model performance.

2. Application Developers: They have robust programming skills but may find AI models opaque. They often require specific input formats, which can lead to suboptimal experiences if not correctly supplied.

3. DevOps and Infrastructure Engineers: Often unfamiliar with AI and application development, they are responsible for deploying models into production, ensuring security, and scaling applications.

This multi-faceted cooperation can complicate the transition of models to production. Research shows that around 50% of models never make it into production, and those that do may take up to nine months post-readiness. Addressing this challenge is the emerging field known as Model Ops, which seeks to create similar benefits for AI model lifecycles that DevOps has provided for application development.

What is Model Ops?

Model Ops contributes to the AI lifecycle in three main ways:

• Automation: Automating processes and providing self-service APIs to minimize the reliance on DevOps teams enhances speed and consistency.

• Integration: Seamless integration with the tools used by data scientists and application developers simplifies the deployment and use of models.

• Open Source Community: Contributing to the growing model ops community enables access to a wealth of resources that can simplify the model release process.

APIs play a pivotal role in these processes, serving as the critical connection point for integration and automation.

Characteristics of a Great API

A great API is designed for both human and machine usage. Here are some crucial characteristics:

1. Semantic Clarity: Use clear language and avoid abbreviations to convey meaning, making it easier for users to understand your API.

2. Intuitiveness: Vocabulary should be tailored to the intended audience, ensuring consistent terminology and avoiding unnecessary technical complexity.

3. Consistency: Adhere to industry standards for authentication, routing, and error handling to reduce the learning curve for users.

4. Error Handling: Provide meaningful error messages that are valuable for both human and machine interpretation.

5. Accessibility: Incorporate a variety of protocols to ensure compatibility with different types of machines, particularly older devices.

6. Declarative API Design: Prefer declarative APIs for ease of use, allowing users to specify desired outcomes without needing to understand complex underlying processes.

Additional Considerations for Emerging Technologies

When developing APIs for rapidly evolving technologies, keep the following in mind:

• Avoid Assumptions: Be cautious of making assumptions about technologies that may change quickly in the AI landscape.

• Keep It Simple: Resist the urge to over-engineer your solution, focusing instead on clear, maintainable architectures.

• Best Practices: Regardless of the technology, apply standard best practices to ensure that the API remains user-friendly.

In conclusion, building effective APIs for AI involves recognizing the diverse needs of users, providing semantic clarity, intuition, and consistency, while remaining adaptable to the fast-paced changes inherent in emerging technologies.

Q2: What are important characteristics of a great API?
A2: A great API should be semantically clear, intuitive, consistent, provide meaningful error messages, be accessible to various machines, and utilize declarative designs.

Q3: Why should we prefer declarative APIs for emerging technologies?
A3: Declarative APIs simplify the user experience by allowing users to specify the desired outcomes without needing to manage complex underlying processes.

Q4: How can organizations ensure their APIs remain relevant amid technological changes?
A4: Organizations should avoid making assumptions about present technologies, focus on simple and maintainable architectures, and adhere to best practices to ensure that APIs are user-friendly and adaptable.
