CAPTCHA has become a familiar part of the internet: distorted texts, “find all the traffic lights” images, audio riddles, and other challenges that distinguish humans from machines. Every bot-system developer or QA engineer automating web scenarios has at least once run into a script suddenly stumbling over a CAPTCHA.

Как уместить ИИ на edge-устройствах

От AlphaGo до ChatGPT — прогресс в области искусственного интеллекта впечатляет своими масштабами. Однако за красивым фасадом скрывается серьезный разрыв между возможностями современных моделей и реальными условиями их применения. Возьмем, к примеру, GPT-3 с его (уже не такими впечатляющими) 175 миллиардами параметров, требующими 800 ГБ памяти. Такие модели существуют только в лабораториях вроде OpenAI. Что уж говорить о запуске подобных систем на устройствах с ограниченными ресурсами.При этом именно edge-у Read more
