OpenAPI Specification

A/B testing with large language models in production is crucial for driving optimal performance and user satisfaction.

A/B Test Prompts and Models

LLMs are **costly** to run. As their usage increaases, the providers have to balance serving user requests v/s straining their GPU resources too thin. They generally deal with this by putting _rate limits_ on how many requests a user can send in a minute or in a day.

LLMs are highly capable of following a given structure. By providing a few examples of how the assistant should respond to a given prompt, the LLM can generate responses that closely follow the format of these examples.

 Consider that you have list of support articles that you want to suggest it to users when users search for it. You want to suggest as best fit as possible. With the availability of tools like Large Language Model (LLMs) and Vector Databases, the approach towards suggestions & recommendation systems has significantly evolved.

Build an article suggestion app with Supabase pgvector, and Portkey

Companies often face challenges of scaling their services efficiently as the traffic to their applications grow - when you’re consuming APIs, the first point of failure is that if you hit the API too much, you can get rate limited. Loadbalancing is a proven way to scale usage horizontally without overburdening any one provider and thus staying within rate limits.

Setting up resilient Load balancers with failure-mitigating Fallbacks

Writing the right prompt is often hard to get a quality LLM response. You want the prompt to be specialized and exhaustive enough for your problem. There is a high chance someone else might’ve stumbled across a similar situation and written the prompt you’ve been figuring out all this while. 

Run Portkey on Prompts from Langchain Hub

Portkey can help you easily create fallbacks from one LLM to another, making your application more reliable. While Fallback ensures reliability, it also means that you'll be running a prompt optimized for one LLM on another, which can often lead to significant differences in the final output.

Smart Fallback with Model-Optimized Prompts

Portkeys Prompt Playground allows you to test and tinker with various hyperparameters without any external dependencies and deploy them to production seamlessly. Moreover, all team members can use the same prompt template, ensuring that everyone works from the same source of truth.

How to use OpenAI SDK with Portkey Prompt Templates

Portkey Fallbacks can automatically switch your app's requests from one LLM provider to another, ensuring reliability by allowing you to fallback among multiple LLMs.
