This episode provides an analysis of the capabilities of large multimodal models (MLLMs) in non-verbal abstract reasoning. The experiment employs various versions of the Raven's Progressive Matrices, a standard test for measuring fluid intelligence, to evaluate the models' ability to interpret visual relationships and deduce missing parts of puzzles based on abstract rules. The results show that open-source models underperform compared to closed-source ones, such as GPT-4V, which demonstrate significantly more advanced reasoning capabilities. The study highlights the need to develop more robust evaluation methods for these models and address their limitations, particularly their inability to accurately perceive visual details and provide reasoning consistent with visual information. Finally, the document explores the implications of these findings for the future development of MLLMs and their ethical and strategic implications for companies.

The episode addresses the challenge of ensuring the reliability and consistency of responses provided by large language models (LLMs). It introduces an innovative solution called "Consensus Game," which leverages a game-theoretic approach to harmonize the often contradictory signals coming from generative and discriminative decoding methods. This approach led to the development of the "Equilibrium-Ranking" algorithm, which aims to find a balance between the needs of the generator and the discriminator, optimizing the consistency and reliability of predictions. The algorithm demonstrates excellent performance on various linguistic tasks, but it also presents some limitations, such as dependence on the training corpus and potential bias. Despite these challenges, Equilibrium-Ranking is positioned as a promising tool for improving the quality of responses provided by LLMs, offering considerable added value for companies looking to make the most of language models in their applications.

AI chatbots offer great opportunities, but they can also generate inappropriate content. Red teaming, a security testing process, is used to test chatbots, but it is costly and slow. Curiosity-Driven Red-Teaming (CRT) is a new technique that uses reinforcement learning to create provocative inputs that test chatbot security. This technique is more efficient than traditional red teaming, but it raises questions about AI autonomy and the importance of human oversight.

Large language models (LLMs) like GPT and LLaMA are becoming increasingly powerful, yet a recent study has highlighted a concerning paradox: while these models improve at handling complex tasks, they tend to make more errors in simple tasks. The study examines this phenomenon by exploring the relationship between perceived task difficulty and the accuracy of responses, the models' tendency to avoid answering difficult questions, and their sensitivity to variations in question formulations. The findings show that, despite increases in size and optimization, these models are not yet reliable in contexts where precision is critical, particularly in crucial areas such as health, safety, or law. The study suggests a need to rethink development strategies to ensure more reliable accuracy and response stability, moving away from the purely expansive approach that has so far dominated the field of artificial intelligence.

A group of researchers from MIT has discovered that large language models, such as ChatGPT and Gemini, use a relatively simple method to manage some information. Specifically, to understand the relationships between concepts, these models rely on linear functions, akin to a map that helps them transition from one idea to another. However, this method is not applied to all information, and in some cases, the model uses more complex processes. The discovery of this linear method is significant because it could allow for "teaching" new information to the models, correcting errors, and customizing interactions with users.
