But this may be more a sign of Bard’s current limitations than a long-term strategy. “We spent decades perfecting that experience,” he says. Krawczyk says that Google does not want to replace Search for now. Google has been working on LaMDA for years, she says, and she thinks pitching Bard as an experiment “is a PR trick that larger companies use to reach millions of customers while also removing themselves from accountability if anything goes wrong.” “We are mindful of all the things that can go wrong with large language models.”īut Margaret Mitchell, chief ethics scientist at AI startup Hugging Face and former co-lead of Google’s AI ethics team, is skeptical of this framing. “We’ll get user feedback, and we will ramp it up over time based on that feedback,” says Google’s vice president of research, Zoubin Ghahramani. These early users will help test and improve the technology.

The company is now making the chatbot available for free to people in the US and the UK who sign up to a waitlist. Google has been working on Bard for a few months behind closed doors but says that it’s still an experiment. Like ChatGPT and GPT-4, Bard is fine-tuned using reinforcement learning from human feedback, a technique that trains a large language model to give more useful and less toxic responses.

Google says it will update Bard as the underlying tech improves. But it will say that Bard is built on top of a new version of LaMDA, Google’s flagship large language model. They acknowledged that success depends on improving BART’s reliability, which has seen a decline since last year.Google won’t share many details about how Bard works: large language models, the technology behind this wave of chatbots, have become valuable IP. Most Bay Area employers have already made long-term decisions on return-to-office requirements.Īgency officials said they will track ridership data to determine whether the changes succeeded in growing BART’s customer base. Downtown office workers accounted for a significant share of BART’s ridership in 2019, but many of them now only commute to work two or three times a week, if at all. There are some tradeoffs to the schedule changes, which will not raise operating costs for the fare-dependent agency.Īdded frequencies on evenings and weekends come at the expense of adding five minutes to wait times on weekdays, particularly on the Blue Line to Dublin/Pleasanton.īART ridership has stagnated since last fall, with weekday ridership about 40% of pre-pandemic levels. BART will run six trains per hour, or every 10 minutes, on the Yellow Line on weekdays until 9 p.m. The Yellow Line averages 99 passengers per train car during peak travel times, about twice the amount of any other BART line. The Antioch line is the system’s workhorse line, and its trains are closest to resembling the packed weekday crowds before the pandemic. No other route will benefit more from the new changes than BART’s Yellow Line to Antioch. Trains will run at least every 20 minutes on each line from open to close, benefiting night and weekend riders who now wait 30 minutes or longer on some trips.īART will also run more trains to San Francisco and Oakland international airports on weekdays. 11, weekday and weekend schedules will closely resemble one another.
