In recent years, AI has taken giant leaps, fueled by key developments in deep learning, transformer models, and scaling. I will briefly review this progress and then turn our attention to the open\n                      challenges we are still facing. Despite the recent advancements, AI is still in its infancy. All AI systems still struggle with basic tasks. I will illustrate these challenges with examples from post-training and evaluation, focusing\n                      on core capabilities such as instruction following, factuality, and multilinguality. Addressing these challenges is crucial to realizing the full potential of AI and ensuring its responsible development.<\/p>\n                  <\/div>\n                <\/div>\n              <\/div>\n

While these models demonstrate remarkable linguistic fluency,\n                      the extent to which they genuinely grasp word semantics remains an open question. In this talk, we investigate the disambiguation capabilities of state-of-the-art instruction-tuned LLMs, benchmarking their performance against specialized\n                      systems designed for Word Sense Disambiguation (WSD). We also examine lexical ambiguity as a persistent challenge in Machine Translation (MT), particularly when dealing with rare or context-dependent word senses. Through an in-depth\n                      error analysis of both disambiguation and translation tasks, we reveal systematic weaknesses in LLMs, shedding light on the fundamental challenges they face in semantic interpretation. Furthermore, we show the limitations of standard\n                      evaluation metrics in capturing disambiguation performance, reinforcing the need for more targeted evaluation frameworks. By presenting dedicated testbeds, we introduce more effective ways to assess lexical understanding both within\n                      and across languages. With this talk we highlight the gap between the impressive fluency of LLMs and their actual semantic comprehension, raising important questions about their reliability in critical applications.<\/p>\n                  <\/div>\n                <\/div>\n              <\/div>\n            <\/div>\n          <\/div>\n        <\/div>\n      <\/div>\n      <div data-colibri-id=\"5976-c44\" class=\"h-row-container gutters-row-lg-1 gutters-row-md-1 gutters-row-0 gutters-row-v-lg-1 gutters-row-v-md-1 gutters-row-v-1 style-2199 style-local-5976-c44 position-relative\">\n        <!---->\n        <div class=\"h-row justify-content-lg-center justify-content-md-center justify-content-center align-items-lg-stretch align-items-md-stretch align-items-stretch gutters-col-lg-1 gutters-col-md-1 gutters-col-0 gutters-col-v-lg-1 gutters-col-v-md-1 gutters-col-v-1\">\n          <!---->\n          <div class=\"h-column h-column-container d-flex h-col-lg-auto h-col-md-auto h-col-auto style-2200-outer style-local-5976-c45-outer\">\n            <div data-colibri-id=\"5976-c45\" class=\"d-flex h-flex-basis h-column__inner h-px-lg-1 h-px-md-1 h-px-1 v-inner-lg-1 v-inner-md-1 v-inner-1 style-2200 style-local-5976-c45 position-relative\">\n              <!---->\n              <!---->\n              <div class=\"w-100 h-y-container h-column__content h-column__v-align flex-basis-100 align-self-lg-start align-self-md-start align-self-start\">\n                <!---->\n                <div data-colibri-id=\"5976-c46\" class=\"h-divider style-2198 style-local-5976-c46 position-relative h-element\">\n                  <!----><span class=\"h-divider__line style-2198-line style-local-5976-c46-line style-2198-line style-local-5976-c46-line\"><\/span><\/div>\n              <\/div>\n            <\/div>\n          <\/div>\n        <\/div>\n      <\/div>\n    <\/div>\n  <\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Baby Steps and Giant Leaps: Where AI Is Today Tuesday (11.3.25), 9:00 \u2013 10:00 Slav Petrov Vice President, Research,&nbsp;Google DeepMind Bio: Slav Petrov is Vice President, Research at Google DeepMind.
