AI transitioned from a phase of incremental improvements and text-based chatbots to an era characterized by **complex reasoning**, **native multimodality**, **cinematic video generation**, and the world's first **comprehensive legal frameworks**.\n\n---\n\n## 1. The Dawn of \"Thinking\" and Reasoning Models\nPreviously, Large Language Models (LLMs) relied heavily on \"next-token prediction,\" which could lead to rapid but sometimes logically flawed answers. In 2024, the paradigm shifted toward **inference-time compute** (or \"slow AI\"), where models are trained to \"think\" before they respond:\n* **OpenAI o1:** Released in late 2024 (initially as `o1-preview` in September, followed by a full release in December), this model series uses reinforcement learning to produce internal chains of thought. It demonstrated unprecedented, human-expert-level capabilities in complex mathematics, coding, and scientific problem-solving.\n\n## 2. Native Multimodality & Massive Context Windows\nAI became highly proficient at interacting with multiple data formats (text, audio, and video) simultaneously and natively:\n* **OpenAI GPT-4o:** Launched in May 2024, \"omni\" represents a natively multimodal model trained to process and generate text, audio, and visual inputs in real-time, enabling ultra-low-latency, human-like voice conversations.\n* **Google Gemini 1.5 Pro:** Google broke boundaries by introducing a **1-million-token context window** (later expanded even further), allowing users to upload entire movies, hundreds of thousands of lines of code, or massive library documents for instant analysis.\n* **Meta’s Open-Source Push:** Meta released **Llama 3** and **Llama 3.2**, cementing the power of open-source models by bringing highly capable, lightweight, and multimodal LLMs directly to edge devices and developers globally.\n\n## 3. The Leap in Video Generation\nVideo AI evolved from chaotic, distorted clips into a professional-grade creative tool with a deep understanding of physical space:\n* **OpenAI Sora:** Unveiled in early 2024, Sora stunned the industry by generating highly realistic, 60-second video clips complete with complex camera movements and persistent characters.\n* **Google Veo:** Google's cinematic video generator emerged to provide fine-grained director controls, physics simulations, and high-fidelity generation, allowing AI-generated footage to be practical for commercial production.\n\n## 4. Consumer Integration: Apple Intelligence\nRather than remaining restricted to developer playgrounds and standalone websites, AI became deeply integrated into consumer hardware:\n* Announced at WWDC in June 2024 and officially rolling out with iOS 18.1 in October, **Apple Intelligence** brought on-device and private cloud-based generative AI to millions of Apple users. It introduced system-wide writing tools, smart notifications, Clean Up in Photos, and deep Siri upgrades (partially powered by a partnership with OpenAI).\n\n## 5. AI in Scientific Discovery\nAI solidified its role as an indispensable tool for science, culminating in the highest level of academic recognition:\n* **The Nobel Prize in Chemistry:** Demis Hassabis and John Jumper of Google DeepMind were awarded the 2024 Nobel Prize in Chemistry for their work on **AlphaFold**, an AI system that solved the 50-year-old challenge of predicting protein structures.\n* **AlphaProteo:** Google also unveiled AlphaProteo, an AI model designed to generate novel, highly effective protein binders to accelerate drug discovery and biological research.\n\n## 6. The First Major Legislation: The EU AI Act\nThe regulatory \"Wild West\" of AI officially began to close in 2024:\n* **The European Union AI Act** officially entered into force on **August 1, 2024**. As the world’s first comprehensive horizontal legal framework for AI, it introduced strict, risk-based categories (ranging from \"minimal risk\" to \"unacceptable risk\") to govern how compani","status":"success","sources":[{"url":"https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQGbxrBAzJntu1EWXnANkHrFOyzBt8WMf7NFCTNdTzBtnJ3sb3IutJQuGksAGEK_Irxh969qG6K2P6SljoGOgu9M_Yv01TDNv9nUWY63YDB_QOu2i9ezI5SffWDwKRAMwYgyHBkzHJQuJl-SASPgyv3Eg-Os4BkL5eEbPmiVMz4MrQ==","title":"sectionai.com"},{"url":"https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQHo17H-pHn5mJRHlT8Elq5mmWbnEhgpwSaO2XgfaUQ9BkLHSZHy5jhOWcvOOjps8wxcZc7EhhrEVAMJ8nf3uk_-Paocu6GI22KEBO79N2CC9LQpaww63SYRf8qhdS1nNeCU8YL4ouMHgfwd3S1iSAhCaS5_kPg6vazEKtHNatdk2ZhH1wG3RDp6OakT9cuL8mTE9zR4TN3QXiRK-mg=","title":"forbes.com"},{"url":"https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQEPakdzzEvpYkYmBTGCMMalRO4okoUpZhDm3-52XV0JG4fRSO3oHV8S4cDYOxPDpfYLfij_GpFGgSaJstSSo00NIKrRA7ZXdyRtAZTuj-Ot2AchPqg8K4YydJzII6UPgK1soIJPygzRpYlI4-lU_urOTA==","title":"swiftchipinc.com"},{"url":"https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQGTINk7U4sOyoUVGhSGKRwGiGuusbfUHzn8wfIefqROdFA2QPIP5nk_loDIitTrUhnRh2e2xr8uLLuipP_-iZftiba5qyKfU14bJLfO1AFOwEx3rf-gkez5Xa2fxspoXj3U-QAtH0kba-ZhJkm6YZBv9AkkAricDPWrv8JLxMZV","title":"europa.eu"},{"url":"https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQFRzxvXECiqX6z5q5CLo_bM4sLsErRbkvvCzzh-wGNC_zaSzn_2B9vW2jlmszhEbdfj11mlVdyHYzvo6IIuFJcVlkstTYfU_Yvm6yp6Esf1gzDE5TuQ-Rnc9MFxed0=","title":"wikipedia.org"},{"url":"https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQG5HR5ep-LZh9m065XAyzm1iN_84lsW08kMslDmpc_rTk6QTwLl2lXDFgsI2UAet7pndrkDWtXkZRn2VR_DmKZQtguI-7vayDNAKgZZBt8AAk7Qecde1GoNCYjQg-G9rIEj_1A=","title":"learnprompting.org"},{"url":"https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQHu5nm1wNJY4px0nTda-8rtYiPlPjYGpsXLOdUdfajH5MHaJNIV1Oxi7gMwzyD1ImwvjfhNh5l3A1t1KxexhEaSMAbwAU3uGky-s0-ggK7JPP03GoBs_sh3Ad3U1YAnXUQ=","title":"youtube.com"},{"url":"https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQGk2jXcUDL2fjMHiGhwOyJYFGr6JbJqRkvbIRFQaMY8dfaoNr2-t5_cypmAMu3UpOa-17H6z0sRpyqGgFBiUMCZ0Q8W2dlbiponj7w6TaSJjAfdftE4ePYYbVubb7lIpCyge8kS9VnPhdwS2A_-bCmz-UAuW--P4JGIS7SNIfPwxOaCePZZ-OcvxnjbBuff3MBFt_1j","title":"apple.com"},{"url":"https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQEpA9PFoD5ctehrXhcRie5jfbBFHqANZzvPwlr4SEOV9wvEfe99QPhkdkXNZIqVRHNSClKnw0Px6oVMtDIhhc5M8KGV5v1s0eN7dpCUkQLEXYfX0XPFeuuaIxXPK1t5Se_ziGPZnTnrjbl7_fWC47GDuU0ltFtmMNGZLvnlhCx0FFk3I9I3tDOZ61CxPU6GcA==","title":"blog.google"},{"url":"https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQFpz8jN54qG2P9ayY6S88k1cmQfL1gbBTZCOMkXxWNCd7HP9caSlLDewHxhV45Ssfcokze1oPwQmsOAx4PYm5qrlPbEgSdm2FheOUY_LEaw0YPGwx0FqU_c2K_jrbJSHquD1y2eAhhfiVOPDDvqfGFHfMdB1rzq1oMzrBNt2V905akR1ltLXqFlO9GMRI2NiPi1YzfyPTxgh2UV","title":"apple.com"}]}},"exampleRequest":{"prompt":"What are the latest developments in artificial intelligence in 2024?"},"tags":["x402"],"displayCostAmount":"0.1","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"settled","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.1/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.1","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.1","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_YMfC9_VpaVBIh6uBVMAj5","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.1","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Performs live AI-powered research on any topic using Gemini Flash with web search, and can analyze images or summarize webpages from URLs","exampleAgentPrompt":"Can you research what is causing the recent spike in Ethereum gas fees?
