Current models

Augment uses world-class large language models together with our Context Engine. We currently support the following models:
  • Claude Sonnet 4 by Anthropic
  • GPT-5 by OpenAI

​
Choosing a model

You can select the model directly using the Model Picker in the Augment panel. Choose between Claude Sonnet 4 and GPT-5 based on your preference or task needs.
  • In VS Code and JetBrains, open the Augment panel and use the model dropdown near the input box to switch models.
  • Your selection applies to Chat, Agent, and Completions in that workspace and can be changed at any time.
Model Picker in Augment panel If you don’t pick a model, Augment will use your last selection or the default set by your organization.

​
Feature compatibility

Both models support the core Augment features:
  • Deep code understanding with Augment’s Context Engine
  • Chat, Agent, Next Edit, and Code Completions
  • Tool use (integrations and MCP), file edits, and multi-step planning
Some behaviors (e.g., wording or style) may vary slightly between models. We’ll continue to refine prompts and guardrails to provide a consistent developer experience.

​
Notes and transparency

  • We may roll out model updates gradually. If you’re part of a staged rollout, different workspaces or teammates may see updates at different times.
  • For troubleshooting, you can share the request ID with our support team; they can confirm which model handled a specific request.
If you have questions about model availability or want to participate in early access programs, please reach out via Support.
