The next leg of the AI race is on, and has expanded beyond the usual players, such as OpenAI, Google, Meta, and Microsoft. In addition to the dominance of the tech giants, more open-source options have now taken to the spotlight with a new focus in the AI arena.
Various brands, such as DeepSeek, Alibaba, and Baidu, have demonstrated that AI functions can be developed and executed at a fraction of the cost. They have also navigated securing solid business partnerships and deciding or continuing to provide AI products to consumers as free or low-cost, open source models, while larger companies double down on a proprietary, for-profit trajectory, hiding their best features behind a paywall.
The latest models, such as DeepSeek's R1, Alibaba's Qwen2.5-VL, and Baidu's Ernie 4.5 have been compared to the top models such as OpenAI's 4o or GPT-4.5 models. Meanwhile, their codes are easily accessible at repositories, such as GitHub or Huggingface for developers to use on unique applications.

DeepSeekDeepSeek, short for Hangzhou DeepSeek Artificial Intelligence Basic Technology Research Co., Ltd., is a Chinese AI startup that gained international attention after its AI models proved to be formidable in quality to those of well-established brands in the industry, including OpenAI, Google, Meta, Microsoft, and others. The company showcased AI models developed in a fraction of the time and operating cost of competitors' models.
The young company has been around since April 2023, an offshoot of the parent company High-Flyer, but has developed several AI models. These include the original DeepSeek-LLM, DeepSeek-Math, DeepSeek V2, and DeepSeek V3– the last of which was announced in November 2024 and was already gaining industry attention. The brand announced its DeepSeek-R1 and DeepSeek-R1-Zero reasoning models in January 2025, which took the AI industry by storm with comparisons to OpenAI's GPT-4 and o1 models. The infamous introduction affected stock prices, made competitors rethink business strategies, and caused security concerns among government entities.
DeepSeek was released under the MIT License, which indicates it is as open as it can be without being 100% open source. The company calls its AI models "open weight." Still, they are available on the GitHub repository for users to download and develop.
DeepSeek is a chatbot-style AI tool that is available in web-based format as well as through iOS and Android mobile applications. Since gaining notoriety, the company has partnered with several companies, including Lenovo, Tencent, Alibaba, and Baidu, among others, to use its AI models.
Alibaba QwenAlibaba Qwen, short for Tongyi Qianwen, a large language model family, is among the top 10 open-source models in the world. Alibaba itself is a notable Chinese e-commerce brand. The company announced its first model as a beta in April 2023, which quickly became popular in the AI space as it officially released models as open source throughout the year.
Subsequent models have been released as either partially or fully open source, including Qwen 2, Qwen-VL2, Qwen-vl-max, Qwen-Audio, and Qwen2-Math. The company's most recent models include Qwen 2.5-Max, which was announced in January 2025, and Qwen2.5-VL, which was announced in March, marketing them as more powerful than rival models such as OpenAI's GPT-4o, DeepSeek-V3, and Meta's Llama-3.1-405 B LLMs.
The original Qwen model was based on Meta's Llama LLM– another open-source model, modified to suit Alibaba's processes. Future models have been released under the Apache 2.0 License and can be found at the GitHub and Huggingface repositories.
Qwen is a chatbot-style AI tool that is available in web-based format as well as through iOS and Android mobile applications. Since its inception, over 90,000 independent models have been developed based on Qwen's open-source code.
Baidu Ernie botThe Ernie Bot, short for Enhanced Representation through Knowledge Integration, is a chatbot developed by Baidu, a well-known Chinese internet brand. While Baidu has been developing its ERNIE model since 2019, it first released the Ernie 3.0 LLM in March 2023.
Since then, it released Ernie 3.5 in June 2023 and Ernie 4.0 in October 2023. The 4.0 model was reserved for Baidu's subscription-based products, while the 3.5 model was used for the brand's free chatbot.
Currently, the Ernie model is not open source; however, the brand plans to soon make it more available to the public in response to increasing competition in the AI industry, as well as due to rapidly reducing production costs.
Baidu released its Ernie 4.5 LLM, and Ernie X1 reasoning model in mid-March, which has been compared to OpenAI's GPT-4.5 and DeepSeek R1, respectively. The brand has plans to make its models open source on June 30. Additionally, the company announced that its chatbot will be free to all users as of April 1. A future model, Ernie 5 is expected to be released during the second half of 2025, similarly being open source and free to use.
Ernie is a chatbot-style AI tool that is available in web-based format as well as through iOS and Android mobile applications. Since its inception, Ernie has been used as the model for the AI integration on an international version of the Samsung Galaxy S24 series.

ASU+GSV 2025: When To Use Custom AI Chatbots, Podcasts, Agents
SAN DIEGO — Tina Austin, a stem cell biologist and lecturer in California universities, said when it comes to artificial intelligence, there are "too many tools, too little strategy."At the AI Show last weekend, a three-day addition to the ASU+GSV Summit focused solely on artificial intelligence and its educational applications, she offered guidelines for when it's best to use emerging technologies in the classroom — namely custom GPTs, AI podcasts and AI agents — and when it's best not to use tech at all.
CUSTOM GPTS Custom GPTs allow users to tailor chatbots to specific uses. Austin uses a paid version of ChatGPT's custom tool to create hers, inputting a description of the chatbot's intended purpose and uploading materials for the bot to reference in its responses. This makes the scope of knowledge much smaller than traditional large language models, but ensures information comes from vetted sources.For example, in her regenerative medicine course, Austin created one chatbot called the "regenerative medicine mentor" as a way for students to ask general questions around the clock. While Austin found that traditional AI chatbots often got science and math problems in this area wrong, her custom GPT gave students accurate answers to their questions.
Austin said custom GPTs are a good tool to use for giving students reliably correct assistance with low-stakes concepts. When students need help with high-order thinking, she said, skip the GPT.
To decide whether to deploy a custom GPT, she said educators should weigh the benefit of hearing questions directly from students and being involved in their problem-solving process against the time-saving power of outsourcing that process to an AI tool."Use [custom GPTs] when students need specific advice exploring a complex lesson of your choice," she said. "Skip it when you don't have time to test and monitor the responses, and you need to personally make sure that they understood."
Austin said she has also created custom GPTs to serve as coaches for students. To do this, she provides the GPT with all the same information she shares with students, and students can ask the chatbot questions to make sure they are on track with their assignments each week. She said this can be especially helpful for long-term projects that require pacing.
The ASU+GSV Summit's supplemental AI Show in San Diego ran from April 5-7.
If a student misses a class, the chatbot lets them know what happened in class that day. If students want more interactive advice on how to study for an upcoming exam, it can draw on course materials to provide accurate study guides. Fielding these simpler questions frees up time for Austin."Right now, I'm teaching four different classes in four different disciplines across three schools, so if I did not have AI, honestly it would be a whole challenge," she said. "But it is important to keep an eye on everything."
AI PODCASTS Google's NotebookLM, Austin's tool of choice for AI podcasts, takes materials users upload and turns them into conversational podcasts. According to Austin, the podcast format can hook students on topics they otherwise aren't very interested in and work with their mobile lifestyle.Austin uploads lecture notes and uses the platform to create alternate ways of engaging with the material.
"Use it when you want to get creative, when you want to be accessible," she said.
However, she recommended not using it when you don't have time to review the finished product before sharing it, and not making the podcast too long. Seven to nine minutes is the sweet spot, she said.
"In my case, I had it talk about regenerative medicine. Halfway through, it said I was a cardiologist, it was mispronouncing some scientific names, it was going off the rails," Austin said. "And there were some issues with the biases, where the female voice was like, 'Oh, wow, I didn't know that' and the male voice was very intelligent."
Instructors can add parameters to the request and regenerate the podcast if they encounter similar problems, Austin said, and should keep in mind that some complex topics may be better served without it.
AI AGENTS AI agents, which have the most decision-making power of these tools and can run on their own, are best for high-repetition tasks that instructors would like to automate, Austin said.For example, Austin uses an AI agent to send students summaries of notes and discussions each week without needing additional prompting. It just takes granting access to the learning management system, in her case Canvas, once.
"I can actually turn off my laptop, go on vacation, and it will keep sending students summaries and notes every week," she said.
Austin likes to think of these tools like chess pieces, differing in number and ability but working together. It might make sense to use one AI agent and two custom GPTs, for example, to best assist one instructor. Like chess, it takes a cohesive strategy to be successful.
