LaMDA
LaMDA is Google's legacy conversational AI model that pioneered open-ended, sensible dialogue — so researchers and developers could explore natural, context-aware chat without rigid scripting (now evolved into Gemini).
About LaMDA
LaMDA (Language Model for Dialogue Applications) is (was?) Google's groundbreaking 2021–2023 research model that showed AI could hold open-ended, sensible, specific, and interesting conversations, paving the way for modern chatbots like Gemini.
Trained on 1.56 trillion words, it focused on "sensibleness, specificity, and interestingness" to avoid generic or off-topic responses.
The model sparked global discussion in 2022 when an engineer claimed it showed signs of sentience (Google denied this).
LaMDA tech was fully integrated into PaLM and Gemini pathways. It's no longer a standalone product or API - all public/developer access is through Gemini (the current flagship).
