LLaMa-2: лучшая опенсорсная языковая модель (by Meta)
Авторы обновили обучающий датасет, сделав его чище и больше (2T токенов), добавили более быстрый grouped-query attention, удлинили контекст до 4k токенов и учили в несколько этапов: pretraining, supervised fine-tuning, RLHF.
Из интересных наблюдений — RL не просто портит калибровку вероятностей (что первыми заметили openAI), а на самом деле корректирует температуру, балансируя между фактологической точностью и креативностью, в зависимости от промпта.

Apparently upbeat developments in Russia's discussions with Ukraine helped at least temporarily send investors back into risk assets. Russian President Vladimir Putin said during a meeting with his Belarusian counterpart Alexander Lukashenko that there were "certain positive developments" occurring in the talks with Ukraine, according to a transcript of their meeting. Putin added that discussions were happening "almost on a daily basis." That hurt tech stocks. For the past few weeks, the 10-year yield has traded between 1.72% and 2%, as traders moved into the bond for safety when Russia headlines were ugly—and out of it when headlines improved. Now, the yield is touching its pandemic-era high. If the yield breaks above that level, that could signal that it’s on a sustainable path higher. Higher long-dated bond yields make future profits less valuable—and many tech companies are valued on the basis of profits forecast for many years in the future.
