Keep every language surface safe and consistent

You treat model output, tool results, resources, notifications, and catalog text as untrusted. Generated language packages preserve the shared Ax contract through native APIs.

axllm.SetRateLimiter(globalLimiter)
axllm.SetTracer(tracer)
axllm.SetMeter(meter)
workflow.ForwardWithHooks(ctx, client, input, nil, axllm.AxRuntimeHooks{RateLimiter: callLimiter, Tracer: tracer, Meter: meter})

Run itIn your own project

go get github.com/ax-llm/ax/packages/go

package main

import (
    "context"
    "fmt"
    "os"

    axllm "github.com/ax-llm/ax/packages/go"
)

func main() {
    client := axllm.NewAI("openai", map[string]axllm.Value{"apiKey": os.Getenv("OPENAI_API_KEY")})
    classify := axllm.NewAx("review:string -> sentiment:class \"positive, negative, neutral\"", nil)
    result, err := classify.Forward(context.Background(), client, map[string]axllm.Value{
        "review": "Useful and boring in the best way."
    }, nil)
    if err != nil {
        panic(err)
    }

    fmt.Println("sentiment:", result.(map[string]axllm.Value)["sentiment"])
}

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