The Kodacode VS Code extension can use models in chat, agent, and edit workflows. To connect LLMEasy, add an Any OpenAI-compatible API model and use a GPT Key group API Key.
This guide uses the VS Code extension as the example. The Kodacode installation docs list VS Code 1.75 or newer as the minimum version, and the extension ID is Koda.koda.

​
Prerequisites

  • VS Code is installed
  • The Kodacode / Koda extension is installed
  • LLMEasy API Key (register here)
  • The API Key belongs to the GPT Key group
  • A GPT Key group model ID copied from the model plaza, for example gpt-5.5

​
Setup

1

Open the Koda panel and add a model

Open the KODA panel in the VS Code sidebar, click the model selector below the input box, and choose Добавить модель: Agent / Add model: Agent.
Choose Add model: Agent from the model selector in the Koda panel.
2

Fill in the OpenAI-compatible model settings

In the add model dialog, use these values:
FieldRecommended value
ProviderAny OpenAI-compatible API
API Basehttps://www.llmeasy.ru/v1/
Model IDA GPT Key group model ID from the model plaza, for example gpt-5.5
API KeyYour LLMEasy API Key
Click Подключить / Connect after filling in the fields.
Select Any OpenAI-compatible API in the Kodacode add model dialog and fill in API Base, Model ID, and API Key.
3

Confirm that the model is active

After the connection succeeds, select the new model, such as gpt-5.5, from the model selector under the Koda input box. Send a short message to confirm that it returns a response.
4

Check config.yaml

Kodacode writes the configuration to ~/.koda/config.yaml. Open this file to confirm that the model was added.
Kodacode config.yaml with the OpenAI-compatible model configuration added.

​
config.yaml example

Use this full structure as a reference. Replace YOUR_API_KEY with your LLMEasy API Key, and do not commit a real API Key to your repository. 
name: Koda
version: 0.0.1
schema: v1
models:
  - name: Koda Models
    provider: koda-chat-models
    model: AUTODETECT
    roles:
      - agent
      - chat
      - edit
  - name: gpt-5.5
    provider: openai
    model: gpt-5.5
    apiKey: YOUR_API_KEY
    apiBase: https://www.llmeasy.ru/v1/
    roles:
      - agent
      - chat
      - edit
context:
  - provider: code
  - provider: docs
  - provider: diff
  - provider: terminal
  - provider: problems
  - provider: folder
  - provider: codebase
If you use a model other than gpt-5.5, update both name and model so they match the GPT Key group model ID from the model plaza.

​
Troubleshooting

  • If the connection fails, confirm that API Base is https://www.llmeasy.ru/v1/ and keep the trailing /.
  • If the model is unavailable, confirm that Model ID comes from the GPT Key group.
  • If authentication fails, copy the API Key again and avoid extra spaces or line breaks.
  • If config.yaml changes do not apply, restart VS Code or run Developer: Reload Window.
  • LLMEasy usually does not require an extra User-Agent or custom headers.
