Choosing a Model
Versors gives you access to multiple AI models. Every plan includes all models - you choose which one to use for each conversation.
How It Works
Models run through two different harnesses under the hood:
Claude Agent
Sonnet 4.6, Opus 4.5, Opus 4.6, Haiku 4.5
Our primary harness. Claude models have full access to all Versors tools and capabilities.
OpenCode
GPT-5 Nano, Grok 4.1 Fast, Gemini 3 Flash, Kimi K2.5
Powers all other models. These are solid options and users can explore them to see if they fit their specific needs.
Our Recommendations
Best for most knowledge work - writing, analysis, building apps, and general coding. The go-to model for everyday use.
Best for chatting, quick edits, and saving tokens. Fast and cheap for lighter tasks.
Best for complex coding, large refactors, and deep reasoning. Note: Opus eats a lot of tokens, so reserve it for when you really need it.
Selecting a Model
Use the model dropdown at the top of the chat panel to switch models for the current conversation.
To set a default model for all new conversations on a machine, open the Settings window from the desktop and choose your preferred default.
