Use Kilo Code with open-source models hosted in the EU
Kilo Code is an open-source coding agent for VS Code, JetBrains and the terminal. It accepts custom OpenAI-compatible providers, either through its settings dialog or in kilo.jsonc. Add inference.eu and your agents work on open-weight models processed in European data centres.

Set it up in a few minutes
- 1
Create an API key in your inference.eu account and export it as
INFERENCE_EU_API_KEY. - 2
In the extension, open Settings, go to the Providers tab and click Custom provider at the bottom.
- 3
Enter
inference-euas the provider id, choose OpenAI Compatible as the provider API, and paste the inference.eu base URL and your key. - 4
Pick the models Kilo fetches from the endpoint, or edit
~/.config/kilo/kilo.jsoncdirectly to set limits and tool calling. - 5
Select an inference.eu model in the model picker and start a small task to confirm that edits work.

}What Kilo Code is
Kilo Code is an open-source AI coding agent available as a VS Code extension, a JetBrains plugin and a command-line tool. It offers modes for different kinds of work, such as architecting, coding, debugging and answering questions, and it edits files and runs commands with your approval.
Kilo supports a long list of built-in providers and lets you add your own. Any endpoint that implements the OpenAI Chat Completions API can be registered as a custom provider, which is how you connect inference.eu and keep your agent work on European infrastructure.
How the configuration works
The custom provider dialog asks for a provider id, a display name, the provider API and a base URL. Choose OpenAI Compatible for the API and enter the inference.eu base URL ending in /v1. When the URL and key are valid, Kilo queries /v1/models and shows a searchable list of models to add.
For finer control, edit kilo.jsonc in ~/.config/kilo/ or in your project. The provider block uses the same shape as the example: an npm adapter, options.baseURL, options.apiKey with {env:...} syntax, and a models map. The model key selects the default as inference-eu/<model id>. Per model you can set tool_call, reasoning and limit.
Which models to choose
For the Code mode and agentic tasks, qwen3-coder-480b-a35b-instruct is a strong default. It is trained for code and tool use and keeps edits focused. For Architect and Ask modes, where the agent reads and reasons more than it edits, glm-5.3 and kimi-k3 give thorough answers.
gpt-oss-120b responds quickly and suits Debug sessions with short loops of trying and checking. Mark models with "tool_call": true in kilo.jsonc so Kilo knows it can give them tools. You can switch models per mode, so it is worth testing each one on the kind of work it will do most.
Troubleshooting
A 401 error means the key did not reach Kilo. If you use {env:INFERENCE_EU_API_KEY}, start VS Code or the CLI from a shell where the variable is set. If the model list stays empty after you enter the base URL, check that it ends in /v1 and has no extra path.
"Model not found" means the model key differs from the inference.eu id. If the agent describes changes without applying them, the model is not returning tool calls: set "tool_call": true and pick a model trained for tool use. Kilo also accepts full endpoint URLs in the base URL field, but the plain /v1 base is the cleanest choice.
Keeping code and data in the EU
With a custom provider, Kilo sends model requests from your editor or terminal to the base URL you enter. With inference.eu, prompts, file contents and command output are processed in EU data centres and never used for training. We sign a data processing agreement under Article 28 GDPR, share our subprocessor list and bill in euros.
Kilo also offers its own gateway and sign-in. If all model traffic must stay with inference.eu, make the custom provider your only one, set its model as the default for every mode, and review Kilo's telemetry setting.
