We're excited to announce two powerful new models are now live on Babbily for all users.

ChatGPT 5.3 Powered by gpt-5.3-chat-latest, this is OpenAI's best general-purpose model from the GPT-5 flagship family. The biggest improvement? It's significantly less annoying β€” fewer unnecessary refusals, less moralizing preamble, and more direct answers. When a useful answer is appropriate, the model delivers it without burying it under caveats. In practice: fewer dead ends, more helpful responses.

Gemini 3.1 Flash Google's latest workhorse model for high-volume use cases. Gemini 3.1 Flash Lite Preview already outperforms 2.5 Flash Lite on overall quality and lands close to full 2.5 Flash performance. Notable improvements span audio input/ASR, RAG snippet ranking, translation, data extraction, and code completion β€” making it a strong pick for fast, cost-efficient tasks.

Both models are available now across the platform. Go try them out.
