Model Selection

Qodo Merge supports a wide range of LLMs (Large Language Models). This guide walks you through configuring different models, including commercial APIs, open-source models, and local setups.

This feature is available for On Prem users only.

We strongly recommend keeping the default model.

Only change it if you have clear evidence that another model performs better for your specific use case or language.

Do not change the default model for any other reason.

Qodo Merge works the best with its default model.

Default model

The default models used by Qodo Merge (August 2025) are a combination of GPT-5 and Gemini 2.5 Pro.

Restrict Qodo Merge to use a specific model

To restrict Qodo Merge to using only one model, add this setting to the configuration file:

[config]
model = "..."

The models currently supported are:

• gpt-5

• claude-4-sonnet

• o4-mini

• gemini-2.5-pro

• deepseek/r1

Change model

To switch models, edit the configuration file:

[config]
model = "..."
fallback_models = ["..."]

Some models require additional parameters or API keys, depending on the provider. These can be configured either in .secrets.toml or as environment variables.

Refer to the LiteLLM documentation for up-to-date model-specific variables.
