Adam, a 9-yr old optimizer, is the go-to for training LLMs (eg, GPT-3, OPT, LLAMA).

Introducing Sophia, a new optimizer that is 2x faster than Adam on LLMs. Just a few more lines of code could cut your costs from $2M to $1M (if scaling laws hold).https://t.co/GrMY600lLO 🧵⬇️ pic.twitter.com/bPLCOWcIHZ

Known reinfections had higher Ct values (indicating lower viral loads) with each variant than ones where no record of a previous symptomatic infection existed, here shown in the unvaccinated. 6/9 pic.twitter.com/QRvYQJh9GJ

Vaccines are the single most important tool in our fight against COVID

However, I’ve worried our approach using a narrow single protein mRNA Vax may limit our ability to keep up w the virus

This new data suggests it might

I’ll explain

Big study of ~70k Covid cases showing Omicron's far lower severity of outcomes vs Delta

Symptomatic hospitalisation -53%
Median hospital stay length -70%
ICU admission -74%
Mortality -91%

Major effects among both vaccinated and unvaccinated patients.https://t.co/xxxlYanRVL pic.twitter.com/3fsdd1OLIR

New from today's @UKHSA report is the finding that Omicron has faster vaccine effectiveness waning vs symptomatic infection than Delta (N for Moderna small)https://t.co/viVjY37rNQ which is a replication of what has been seen in Israel @BarakRaveh pic.twitter.com/ynNM0DlRkv

In neutralization assays, @BalazsLab observes only a 4-fold or 6-fold reduction in titer going from wild-type to Omicron after booster relative to 43-fold or 122-fold after initial mRNA vaccine series (https://t.co/EuHC1fuHWP). 4/14 pic.twitter.com/AidMZkxzUd

Under existing control measures, we project a wave of infections resulting from Omicron that exceeds the January 2021 levels, for all four scenarios.

In the optimistic scenario, hospital admissions are projected to remain below Jan 2021 levels. pic.twitter.com/LpZIp4NQxA
