To select a model and interact with the messages and responses in the chat, there are a few functionalities in the chat. These are the model selector in the top left corner and the buttons to interact with prompts and responses.
Langdock is model-agnostic, which means we integrate the best AI models currently available in a GDPR-compliant EU setting, regardless of provider. You can select from current top models like GPT-4.1, Claude Sonnet 4, Gemini 2.5 Pro, and others.To choose a model for your next response, switch it in the top left corner of the chat. Each model has its characteristics. You can learn more about the current models in Langdock in our model guide.
If you’re unsatisfied with a response, edit the prompt by clicking the pen icon. Click save when ready. It’s normal to iterate on your instructions when using AI models and add more context where needed.
To reuse a prompt, save it by clicking the ”+” icon. Choose a folder in your prompt library and give your prompt a name. Learn more about the prompt library here.
If you’re unsatisfied with a response, click the circular arrow to regenerate it. This works because AI models are non-deterministic, meaning you’ll get slightly different results for the same prompt. You can compare multiple responses and pick the best one. If responses are still insufficient, try editing your prompt with more specific details.
