Why Stableoutput

example

API keys stored on browser localStorage

API keys are stored on browser localStorage and API calls to OpenAI and Anthropic are made directly in the browser. API keys are not sent to Stableoutput server.

Popular AI models to use

Chat with OpenAI models like O1 Preview, O1 Mini, GPT-4o, or Anthropic models like Claude 3.5 Sonnet. Easily switch between models to append, edit, or regenerate messages with any of them, in any part of the conversation.

More personalized

Customize your system prompt, temperature, max tokens, and other supported model settings. Adjust settings per chat or apply a global setting for all new chats.

Usage tracking

Every time you use a feature, the usage amount, typically measured in tokens, will be displayed. This helps you monitor your API usage so you don't need to worry about unexpectedly exceeding your API usages.

Chat with PDFs, code-files, and images

Upload images, documents (such as PDFs, CSVs, and more), or coding-related files (such as JS, TS, C, and more) to allow the AI model to analyze them and provide you with relevant information.

Pin chat, share chat, and control over message requests

Pin chat to prioritize a chat over others, share chats with view-only or view-edit capability, and control whether to include previous files or messages within a conversation to help manage API cost, without switching to a new chat or conversation.
