Installation

After installing VeADK Go, you can create, run, and package agents in Go projects. New projects should use the V2 module path by default. Existing V1 projects can stay on the V1 maintenance line.

Prerequisites

Go 1.26.5 or later. This requirement comes from the current mainline go.mod.
A model and API Key are required when you call a model. Installing the module itself does not require model credentials.
To use V2 capabilities, pin to the v2.0.0 tag.

Install V2 for New Projects

Initialize a Go module in your project directory:

mkdir veadk-go-demo
cd veadk-go-demo
go mod init example.com/veadk-go-demo

Pin to the v2.0.0 tag:

go get github.com/volcengine/veadk-go/v2@v2.0.0

Use V2 import paths in your code:

import (
	veagent "github.com/volcengine/veadk-go/v2/agent/llmagent"
	"google.golang.org/adk/v2/agent"
)

V2 contains breaking changes required by ADK v2 and A2A v2. Production projects should pin to v2.0.0 or a validated version.

Install V1 for Existing Projects

If your project still uses ADK v1, install a V1 maintenance release:

go get github.com/volcengine/veadk-go@v1.0.1

V1 import paths do not include /v2:

import (
	veagent "github.com/volcengine/veadk-go/agent/llmagent"
	"google.golang.org/adk/agent"
)

The V1 maintenance branch is release/v1. To inspect V1 examples or fixes, switch to that branch:

git checkout release/v1

Configure the Model

VeADK Go reads .env and config.yaml from the current working directory. .env does not override existing environment variables. Keys in config.yaml are converted to environment variable names and also do not override existing environment variables. As a result, exported environment variables have higher priority than file-based configuration. Create config.yaml in your project root:

model:
  agent:
    provider: openai
    name: deepseek-v4-flash-ga-260731
    api_base: https://ark.cn-beijing.volces.com/api/v3/

Provide the API Key through an environment variable:

export MODEL_AGENT_API_KEY="your-ark-api-key"

You can also configure the model entirely with environment variables:

export MODEL_AGENT_PROVIDER="openai"
export MODEL_AGENT_NAME="deepseek-v4-flash-ga-260731"
export MODEL_AGENT_API_BASE="https://ark.cn-beijing.volces.com/api/v3/"
export MODEL_AGENT_API_KEY="your-ark-api-key"

Do not commit real API Keys, AK/SK pairs, or tokens. Running examples sends prompts to the selected model service and may incur model usage charges.

Verify from Source

To verify V2 capabilities or local changes, clone the source repository:

git clone https://github.com/volcengine/veadk-go.git
cd veadk-go
git checkout v2.0.0

In the source repository, you can run public examples or tests. For first verification, start with examples that do not require an external model, such as the basic Runner example. Examples that call a model require model credentials first.
