Customize Your Chat Experience
Lambda Chat offers several settings to tailor your interaction:
1. Hide Emojis: Keep your conversation titles in the sidebar clean and distraction-free by hiding emojis.
2. Disable Streaming Tokens: Prefer to see the AI's full response at once? Disable token streaming to have answers appear completely instead of word-by-word.
3. Direct Text Pasting: Easily paste text, even long passages, directly into the chat. Enable this option to ensure it's treated as plain text, not as a file or separate inputs.
Access the Lambda Labs API
For developers, Lambda Labs provides an API to integrate these powerful AI models into your own applications. To use the API, you'll need to generate an API key from your Lambda Labs dashboard, which typically requires a credit card for billing purposes.
