Today on the AI Daily Brief why the 2025 AI battle lines are around reasoning models, agents and world models. Before that in the headlines is a new AI mode coming to Google Search. The AI Daily Brief is a daily podcast and video about the most important news and discussions in AI. To join the conversation, follow the Discord link in our show. Notes. Welcome back to the AI Daily Brief Headlines edition. All the daily AI news you need in around five minutes. One of the really fascinating phenomenon that is somehow kind of backseat relative to everything else going on in AI is that for the first time in a very long time, 20 years basically there's competition around what search means. Perplexity is obviously one of the most beloved AI products right now and continues to add to their war chest as well as their feature set. OpenAI is part of their 12 Days of Shipments expanded access to ChatGPT search to the wider world and now the Information is reporting that Google is planning to add an AI mode option to their search as well as the information source is someone who's working on the product who says that Google is planning to, quote, give its billions of search users the option to switch to an AI mode that looks nearly identical to its Gemini AI chatbot. Others have found indications that this shift won't just be about what you type into your computer, but also that there will be a way to talk to search 9 to 5. Google found some indications in the code that suggest you'll be able to use mobile inputs, including voice and photos as a way to search. A Google spokesperson was circumspect about all of this, saying, as our state of the art models continue to advance, there's a huge opportunity to bring these new capabilities into search, helping people discover even more of the web. And to some extent this is absolutely obvious. It feels very likely that in the future there will be simply multiple types of search experiences for different types of queries. The type of perplexity or ChatGPT search, where you're actually trying to get an answer to a question is going to become default for lots and lots of types of queries. I don't think that means that Google's traditional search has no help, but being able to toggle between the two could be really valuable. The challenge, of course, is that a federal judge has already ruled that Google search engine is an illegal monopoly. As the Information writes, the Department of Justice has suggested that it wants to make it harder for Google to leverage its search engines to beat AI chatbot rivals, which could create a legal barrier to something like AI mode This is tough. On the one hand, I absolutely want competition, but on the other, this is just sort of the obvious place to take search for Google, and artificially blocking them from doing so is basically just forcing them to lose. Next up, former Twitch CEO and very briefly, OpenAI CEO Emmett Shear is reportedly working on a new AI startup with some intriguing goals. You might remember that Shear was very briefly named as replacement for Sam Altman as CEO of OpenAI during the leadership controversy in November 2023. Interestingly, he was credited by the Wall Street Journal as clearing the path for Sam Altman's return by effectively immediately threatening to resign if he wasn't given evidence by the board to support Altman's removal. TechCrunch is now reporting that Shir has founded a company called STEM AI with incorporation documents filed in June of last year. The company is still in stealth, so details are very limited, but what TechCrunch uncovered does sound interesting. According to a trademark filed last year, STEM AI is developing software to create AI that, quote, understands, cooperates with and aligns with human behavior, human preferences, human biology, human morality, and human ethics. More hints come from the presence of Adam Goldstein as a co founder. After selling a travel website called HitMonk in 2016, Goldstein became a visiting partner at Y Combinator. He also founded an incubator called Astonishing Labs to back bioresearch startups. According to his LinkedIn page, Goldstein spent a year at Tufts University's 11 labs as a visiting scientist, where he developed new models for biological systems with a focus on cancer. According to PitchBook Goldstein, STEM received backing from Andreessen Horowitz back in August. And while that's all we know right now about the actual company, Shear has been growing increasingly vocal about AI safety and regulation over the past month. In December, for example, he posted almost all currently proposed regulation is a bad idea. He added, though, that ideas around regulating firms rather than AI models and increasing transparency are some of the few reasonable ideas currently being floated. Back in November, he wrote, not being scared of AGI indicates either pessimism about the rate of future progress synthesizing digital intelligence or or severe lack of imagination about the power of intelligence. In June, around the time that California's SB 1047 legislation was being debated, he said on a podcast appearance that his greatest concern was self improving models that could grow out of human control. He said at the time, I'm in favor of creating some kind of fire alarm, like maybe no AI is bigger than X. I think there's good options for international collaboration and treaties about some sort of AI test ban treaty. TLDR Shear is a good operator and this is likely one to watch. Lastly, today, how the mighty have fallen. Intel is courting bids to buy out its Altera programmable chip arm. Altera specialized in the design of low power programmable chips for use in AI enabled devices. The company was spun off as a separate entity in February as Intel attempted to write the ship After a disappointing few years. Bloomberg reports interest from multiple private equity firms including Francisco Partners, Silver Lake Management, Apollo Global Management and Bain Capital. Intel is giving potential buyout partners until January to formalize their offers. Deal terms presented in November range from taking a 20 to 30% stake in the company all the way up to taking full control. Bloomberg reports that Altera is being valued in the range of 9 to 12 billion, a steep discount from the 17 billion intel paid back in 2015. The move comes of course, in the shadow of the departure of CEO Pat Gelsinger. After being brought in three years ago to get intel back on track, Gelsinger retired from his position earlier this month at the request of the board. That, however, is going to do it for today's AI Daily Brief Headlines edition. Next up, the main episode. Today's episode is brought to you by Vanta.

I love it when a set of stories converge in a way that really tells a bigger story than just an individual piece of news. And boy was that the case. Case Today we are looking at what are shaping up to be the 2025 battle lines in AI reasoning models, agents and world models. All of which got some interesting news yesterday. Now of course at this point you probably don't need the background on reasoning models, but effectively this is a new approach to scaling that uses different strategies than just throwing more compute and data in the pre training. This is clearly where OpenAI is putting its emphasis. It released 01 Preview back in September. Subsequent to that we've had Amazon announcing Nova and talking about a reasoning model in the lineup meta releasing Llama 3.3, also emphasizing its reasoning capabilities. Several Chinese labs have also released very competent reasoning models and now Google has joined the party. A few days after their initial launch, Google has added a reasoning model to the Gemini 2.0 flash lineup. The model is called Gemini 2.0 flash thinking experimental hopefully this is just a working title guys, and the way it describes itself is that it's the best in the lineup for multimodal understanding, reasoning and coding. In demonstrations. It seems to perform well on puzzles involving both visual and text clues and so far as novel features that make it stand out from the pack. The model shows its chain of logic so you can see what's going on under the hood, OpenAI co founder Andrej Karpathy wrote. The prominent and pleasant surprise here is that unlike 01, the reasoning traces of the model are shown. As a user, I personally really like this because the reasoning itself is interesting to see and read. The models actively think through different possibilities, ideas, debate, themselves, etc. The case against showing these is that it's typically a concern of someone collecting the reasoning traces and training to imitate them on top of a different base model to gain reasoning ability. Possibly and to some extent. The model is also extremely fast compared to rivals and available for free on Google AI Studio. This in and of itself is pretty surprising as reasoning models so far have been extremely expensive to operate compared to their non reasoning counterparts. One interesting thing here is that Google's naming convention implies that this is just a fine tuned version of 2.0 Flash or perhaps simply the base model with some system prompts to ask the model to think for longer and check its work before answering. Compare that to 01, where OpenAI went out of their way to present it as an entirely new model. Sam Altman even framed the release as the beginning of a different branch of LLMs for the company. One of the big questions I think heading into next year is just how different these reasoning models are from their non reasoning counterparts and more particularly whether they really do evolve in different ways going forward. Now speaking of OpenAI, the other big news for reasoning models is that OpenAI is preparing to release the second generation of their O1 model. Funny enough, speaking of weird naming conventions, according to the information the model is going to be called O3 to avoid intellectual property disputes with British telco O2. Sam Altman all but told us the model would be released today, so it's probably out by the time you're listening to this. The release could answer another big question surrounding reasoning models, which is whether they can show major improvements on the model layer. At the time 01 came out, it was suspected that OpenAI was pivoting to reasoning because adding training data and compute to training runs was showing diminishing returns. In the following months it was confirmed that noticeable improvements could be made to reasoning models by getting them to think longer. Assuming O3 is a brand new model and not a tweak of O, it should reveal whether reasoning models themselves can scale an ability. Or instead, if all of the improvements are only possible by scaling up inference time, the community is pretty excited to check it out. Chubbyonx writes, 03 equals Orion. There is probably no more GPT 4.5 or 5. Everything is summarized in Orion I.e. 03. Surely Orion was fed with a lot of synthetic data from 01 and now has evolved into O3. Chubby also got at the competitive dynamics in the field writing time to take back the crown from Google. We have one more normal episode coming on Monday before we get into end of the year specials, so I will have a chance to follow up on what exactly came out on Friday. Now moving on to the next dimension of competition. The one that's even more obvious than reasoning models in some ways is the race to Deploy agents. Yesterday, OpenAI announced a long list of new integrations for ChatGPT. The desktop application can now access data from a gigantic list of coding platforms, as well as Apple Notes, notion and quip. For now, ChatGPT can only read these apps in context. It can't take actions within those programs. But Chief Product Officer Kevin Weil made it clear that's where this is all going. He said, we've been putting a lot of effort into our desktop apps. As our models get increasingly powerful, ChatGPT will become more and more agentic. That means we'll go beyond just questions and answers. ChatGPT will begin doing things for you. A few weeks ago, Wharton Professor Ethan Malik posted, OpenAI has a lot of pieces on the board right now. Multimodal vision and voice, small, large and reasoning models, image and video creation, code execution, mobile and desktop apps, Web search, semigentic stuff. Very curious when it will be glued together into a singular thing. Interestingly, going back to this quote from Kevin Wheal, it seems extremely notable to me that he says ChatGPT will begin doing things for you. This indicates pretty clearly to me that we have the singular thing that it is and has always been ChatGPT. It's just that over time, ChatGPT is going to be a lot more and frankly different from what ChatGPT originally was. A couple days ago we also got an update from Salesforce on their agent platform, Agent Force. Just three months after announcing Agent Force in September, the company announced Agent Force 2.0. They write, this release introduces a new library of pre built skills and workflow integrations for rapid customization, the ability to deploy Agent Force in Slack and advancements in agentic reasoning in Rag. These advancements will enable companies to scale their workforce with customized agents capable of handling complex multi step tasks with even more precision and accuracy. And if you need a sense of just how important this is to Salesforce, go check out the piece in the Information AI is Marc Benioff's friend and foe. It talks about how Salesforce is facing increasing competition from companies like Sierra which are bringing agents to market and in fact in some cases winning business away from Salesforce. The final vector of competition that I want to discuss today is this new world model approach. These models are trained in a fundamentally different way to LLMs where LLMs are trained on a large corpus of text, image and voice data. World models are trained by observing real or simulated worlds. We've seen a few working prototypes of this style of AI, with two big examples coming out of Fei Fei Li's World Labs and another coming out of Google DeepMind. A third big player is Descartes, who released a model in October capable of generating a fully playable Minecraft like game. While the demo was buggy and rudimentary, it clearly made investors sit up and pay attention. TechCrunch reports that the company has now raised their Series A. The startup raised 32 million at a $500 million valuation. CEO and co founder Dean Ledersdorf said the company wants to compete at the highest level, building a quote, fully vertically integrated AI research lab alongside enterprise and consumer products. He said the aim was to create what he's calling a kilocorn, in other words, a trillion dollar company. You gotta love ambition man. Part of the reason that people are so interested in world models, especially recently, is the sense that perhaps their understanding of physics could be something that allows them to make more fundamental breakthroughs. Still, in many ways, this class of models feels closer to where GPT based LLMs were a few years ago, demonstrating some fascinating emergent properties, but still nowhere near the full scale that they're going to reach. Along those lines, a group of researchers across 19 different universities have just revealed something they are calling a comprehensive physics simulation platform named Genesys. The researchers claim the platform is capable of simulating a wide range of materials and physical phenomena. Researcher Xiaojian writes after a 24 month large scale research collaboration involving over 20 research labs. A generative physics engine able to generate 4D dynamic worlds powered by a physical simulation platform designed for general purpose robotics and physical AI applications. We aim to build a universal data engine that leverages an upper level generative framework to autonomously create physical worlds together with various modes of data including environments, camera motions, robotic task proposals, reward functions, robot policies, character motions, fully interactive 3D scenes, open world, articulated assets, and more, aiming towards fully automated data generation for robotics, physical AI and other applications. So basically, Genesys, as I understand it, can be used as both a robotic simulation platform and as a photorealistic rendering platform. The platform accepts natural language prompts and can be used as a data engine to produce a range of different modalities of synthetic or simulated data. In the immediate term, it's a massive boost to robotics training in terms of speed and accuracy. It could lead to immediate improvements in that field and possibly even unlock more complex use cases. Roboticist Ben Duffy commented, quote, with Genesis, you'll be able to train a locomotion policy that's deployable in real world in less than 26 seconds. That sentence tells us about a future we are not ready for. For reference, that's 430,000 times faster than the previous leading physical simulators. To give a sense of how dramatic this change could be. One of the other potentials is that a platform like this could produce the gigantic data sets required to scale upworld models. Currently they've been trained using either data sets from self driving cars or by observing video games. There are a few projects strapping camera rigs to hikers in order to gather real world data, but if this platform is as performant as the researchers claim, we could soon see near infinite synthetic data sets available to train the next generation of world models effectively. All of the response to this is some version of wow. Viewing their announcement video, AI evangelist Linus writes, this is all generated and simulated in 4D mind blown emoji. Mind blown emoji. Mind blown emoji who writes think instant physics, accurate environments, camera paths and character animations all from natural language. Mila writes, what the this genesis project is like something out of a sci fi movie. I mean, generating entire 40 worlds with physics simulations? That's mind blowing. I'm just sitting here stunned, trying to wrap my head around how this could change everything from robotics to video games. And I think, friends, if we had to sum this up, if you thought that 2025 was going to be any slower than 2024 and 2023 had been, boy do you need to think again. That's going to do it for today's AI daily brief. Appreciate you listening as always. Until next time, peace.
