Meena
Introduced by Daniel Adiwardana et al. in Towards a Human-like Open-Domain Chatbot
archive 2025-07-28 Description, source and code snippet are the archive's method entry.
Meena is a multi-turn open-domain chatbot trained end-to-end on data mined and filtered from public domain social media conversations. This 2.6B parameter neural network is simply trained to minimize perplexity of the next token. A seq2seq model is used with the Evolved Transformer as the main architecture. The model is trained on multi-turn conversations where the input sequence is all turns of the context and the output sequence is the response.

Usage over time archive 2025-07-28
Components: the archive holds no method-to-method composition, so PwC's Components table cannot be rebuilt; the Papers list carries no Results column for the same reason (the archive does not join its leaderboard rows to method tags).
