The historical background of artificial intelligence (AI) can be traced back to Alan Turing's "imitation game," early computational theory, and the development of the first neural networks and machine learning, laying the foundation for today's advanced models.

This evolution has been prominently highlighted by key moments such as the rise of deep learning and reinforcement learning, which are crucial in shaping contemporary AI trends, including the emergence of complex Mixture of Experts (MoE) and multimodal AI systems, demonstrating the dynamic and evolving nature of the field. These advancements illustrate the dynamic and evolving nature of AI technology.

The evolution of artificial intelligence (AI) witnessed a pivotal turning point with the emergence of Large Language Models (LLM), particularly the unveiling of ChatGPT developed by OpenAI and the recent Gemini by Google. This technology has not only fundamentally transformed industries and academia but also reignited critical discussions about AI consciousness and its potential threats to humanity.

The development of such advanced AI systems, including significant competitors like Anthropic's Claude and the current Gemini, which represent several advancements compared to GPT-3 and Google's own LaMDA, has reshaped the research landscape.

Gemini's ability to learn through bidirectional dialogue and its "spike-and-slab" attention mechanism, enabling it to focus on relevant parts of the context in multi-turn conversations, represents a significant leap in developing models better suited for multi-domain dialogue applications. These innovations in LLM, including the Mixture of Experts approach adopted by Gemini, signify a shift towards models capable of handling diverse inputs and promoting multimodal approaches.

In this context, speculation about OpenAI's project named Q* (Q-Star) has surfaced, reportedly combining the powerful capabilities of LLM with complex algorithms such as Q-learning and A* (A-Star algorithm), further fostering a dynamic research environment.

Changes in the Heat of AI Research

With the continuous development in the field of Large Language Models (LLM) reflected by innovations such as Gemini and Q*, a large number of studies have emerged, aiming to outline the future research direction.
