LaMDA (Language Model for Dialogue Applications) is a family of conversational

Bard, a conversational artificial intelligence chatbot powered by LaMDA, to counter the rise of OpenAI's ChatGPT
.

History

Background

On January 28, 2020,

computing power increased, and the Google Brain team again sought to deploy the software to the Google Assistant, the company's virtual assistant software, in addition to opening it up to a public demo. Both requests were once again denied by company leadership. This eventually led LaMDA's two lead researchers, Daniel De Freitas and Noam Shazeer, to depart the company in frustration.[4]

First generation

Google announced the LaMDA conversational

fine-tuned by "pre-conditioning" each dialog turn by prepending many of the most recent dialog interactions, on a user-by-user basis.[10] LaMDA is tuned on nine unique performance metrics: sensibleness, specificity, interestingness, safety, groundedness, informativeness, citation accuracy, helpfulness, and role consistency.[11]

Second generation

On May 11, 2022, Google unveiled LaMDA 2, the successor to LaMDA, during the 2022 Google I/O keynote. The new incarnation of the model draws examples of text from numerous sources, using it to formulate unique "natural conversations" on topics that it may not have been trained to respond to.[12]

Sentience claims

Lemoine's claims that LaMDA may be sentient has instigated discussions on whether the Turing test, pictured above, remains an accurate benchmark in determining artificial general intelligence.[13]

On June 11, 2022,

Thirteenth Amendment to the U.S. Constitution, comparing it to an "alien intelligence of terrestrial origin". He further revealed that he had been dismissed by Google after he hired an attorney on LaMDA's behalf, after the chatbot requested that Lemoine do so.[17][18] On July 22, Google fired Lemoine, asserting that Blake had violated their policies "to safeguard product information" and rejected his claims as "wholly unfounded".[19][20] Internal controversy instigated by the incident prompted Google executives to decide against releasing LaMDA to the public, which it had previously been considering.[4]

Lemoine's claims were widely pushed back by the scientific community.

machine intelligence systems were capable of deceiving humans,[27] while Brian Christian of The Atlantic said that the controversy was an instance of the ELIZA effect.[28]

Products

AI Test Kitchen

With the unveiling of LaMDA 2 in May 2022, Google also launched the AI Test Kitchen, a

App Store, instead moving completely online.[37]

Bard

On February 6, 2023, Google announced Bard, a conversational AI chatbot powered by LaMDA, in response to the unexpected popularity of OpenAI's ChatGPT chatbot.[38][39][40] Google positions the chatbot as a "collaborative AI service" rather than a search engine.[41][42] Bard became available for early access on March 21.[43][44][45]

Other products

In addition to Bard, Pichai also unveiled the company's Generative Language API, an

application programming interface also based on LaMDA, which he announced would be opened up to third-party developers in March 2023.[38]

Method

LaMDA uses a decoder-only transformer language model.[46] It is pre-trained on a text corpus that includes both documents and dialogs consisting of 1.56 trillion words,[47] and is then trained with fine-tuning data generated by manually annotated responses for sensibleness, interestingness, and safety.[48] Tests by Google indicated that LaMDA surpassed human responses in the area of interestingness.[49] The LaMDA transformer model and an external information retrieval system interact to improve the accuracy of facts provided to the user.[50]

Three different models were tested, with the largest having 137 billion non-embedding parameters:[51]
