Unit 2 · Make AI outputs predictable

Connect Ax to the right model

You configure the provider, current model, credentials, and runtime options in one place. Your program contract stays separate from that choice.

Worked example

See the idea in context

var client = Ax.ai("openai", Map.of("apiKey", System.getenv("OPENAI_API_KEY")));

Choose the provider
name selects the provider adapter used by this client.
Read credentials from the host
The API key stays in the process environment instead of browser storage or source code.
Pick a current model
Model selection belongs in provider configuration, not in the program signature.

Run itIn your own project

// Gradle (build.gradle):
implementation 'dev.axllm:ax:24.0.15'
// Maven (pom.xml):
<dependency>
  <groupId>dev.axllm</groupId>
  <artifactId>ax</artifactId>
  <version>24.0.15</version>
</dependency>

import dev.axllm.ax.Ax;
import java.util.Map;

public class QuickStart {
  public static void main(String[] args) throws Exception {
    var llm = Ax.ai("openai", Map.of("apiKey", System.getenv("OPENAI_API_KEY")));
    var classify = Ax.ax("review:string -> sentiment:class \"positive, negative, neutral\"");
    var result = classify.forward(llm, Map.of(
      "review", "Useful and boring in the best way."
    ));

    System.out.println("sentiment: " + result.get("sentiment"));
  }
}

Set OPENAI_APIKEY in your environment before running provider-backed code.
