PaLM 2 is extra highly effective than any current mannequin, primarily based on public disclosures. Facebook’s LLM known as LLaMA, which it introduced in February, is educated on 1.4 trillion tokens. The final time OpenAI shared ChatGPT’s coaching measurement was with GPT-3, when the corporate stated it was educated on 300 billion tokens on the time. OpenAI launched GPT-4 in March, and stated it reveals “human-level performance” on {many professional} exams.
LaMDA, a dialog LLM that Google launched two years in the past and touted in February alongside Bard, was educated on 1.5 trillion tokens, in accordance with the newest paperwork seen by CNBC.
As new AI purposes shortly hit the mainstream, controversies surrounding the underlying expertise are getting extra spirited.
