LLM Native is rapidly transforming the AI landscape. Yet, navigating this uncharted territory can be daunting. Many pioneering developers lack a clear roadmap, often reinventing the wheel or getting stuck.

This frustration ends here.

Through my experience helping organizations leverage LLMs, I've developed a powerful method for creating innovative solutions. This guide serves as your roadmap, guiding you from ideation to production, and empowering you to craft groundbreaking LLM native applications.

Why You Need a Standardized Process

The LLM space is a whirlwind of innovation, with groundbreaking advancements seemingly unveiled daily. This dynamism, while exhilarating, can be overwhelming. You might find yourself lost, unsure of how to bring your novel idea to life.

If you're an AI innovator (manager or practitioner) seeking to build effective LLM native apps, this guide is for you.

A standardized process offers several key benefits:

Team Alignment: Establishes a clear path for team members, ensuring smooth onboarding, especially amidst the ongoing evolution of the field.

Defined Milestones: Provides a structured approach to track your progress, measure success, and stay on the right track.

Risk Mitigation: Identifies clear decision points, allowing you to make informed choices and minimize risks associated with experimentation.

Finding the Right Balance: Bottom-up vs. Top-down

Many early adopters jump straight into complex, state-of-the-art systems. However, I've found that the "Bottom-up Approach" often yields better results.

Start lean, with a "one prompt to rule them all" philosophy. While these initial results might be underwhelming, they establish a baseline for your system. Continuously refine your prompts using prompt engineering techniques to optimize outcomes. As weaknesses emerge, split the process into branches to address specific shortcomings.

The "Top-down Strategy" prioritizes upfront design. It involves defining the LLM native architecture from the outset and implementing its various steps simultaneously. This allows testing the entire workflow at once for maximum efficiency.

In reality, the ideal approach lies somewhere in between. While a good standard operating procedure (SoP) and modeling an expert beforehand can be beneficial, it's not always practical. Experimentation can help you land on a good architecture without needing a perfect initial plan.

The Anatomy of an LLM Experiment

Personally, I prefer a lean approach using a simple Jupyter Notebook with Python, Pydantic, and Jinja2:

Pydantic: Defines the expected output schema from the model.

Jinja2: Writes the prompt template.

Structured Output Format (YAML): Ensures the model follows your defined "thinking steps" and adheres to your SoP.

Pydantic Validations: Verifies the model's output and triggers retries if necessary.

Stabilized Code: Organizes code into functional units using Python files and packages.

For broader applications, consider tools like:

OpenAI Streaming: Simplifies utilizing streaming capabilities.

LiteLLM: Provides a standardized LLM SDK for various providers.

vLLM: Enables working with open-source LLMs.
