Ready to talk to Ernie? DeepSeek's latest rival from Baidu is here
It's a shot across the bow of DeepSeek, China's premier LLM, which has seen unprecedented success since it debuted in December 2024.
It's also a big change of approach for Baidu. The company had previously been vocal in its defiance of moving to open source, working to keep its business model proprietary.
DeepSeek and other international rivals like ChatGPT have proven that being open source can lead to a more impressive LLMs, and still be lucrative.
While the change could not be as monumental as the arrival of DeepSeek, it could have major ramifications for AI.
'This isn't just a China story," Sean Ren, associate professor of computer science at the University of Southern California and Samsung's AI Researcher of the Year told CNBC.
"Every time a major lab open-sources a powerful model, it raises the bar for the entire industry."

"While most consumers don't care whether a model's code is open-sourced, they do care about lower costs, better performance, and support for their language or region," Ren added.
"Those benefits often come from open models, which give developers and researchers more freedom to iterate, customize, and deploy faster."
Baidu's move to open source could also help provide more competition to its aforementioned rivals.
If Baidu's model is able to offer comparative features to rivals, but at a lower price, it could be seen as a moment that reverberates through the industry.
Earlier this year, Sam Altman, OpenAI's CEO, discussed open source models on Reddit.
'While OpenAI has open-sourced models in the past, the company has generally favored a proprietary, closed source development approach,' Altman explained.
'[I personally think we need to] figure out a different open source strategy,' he added.
'Not everyone at OpenAI shares this view, and it's also not our current highest priority … We will produce better models [going forward], but we will maintain less of a lead than we did in previous years.'
Expect Baidu's model to be under plenty of scrutiny, too. This week, Germany moved to ban DeepSeek for transferring data to China.
In AI, the term open-source refers to systems where the code and training data is made publicly available.
This is becoming more common recently, with the likes of OpenAI, Deepseek and Gemini all releasing open-source versions of their products.
With an open-source AI model, the public can inspect, adapt and distribute the code in their own way. This speeds up the process for smaller companies who aren't able to put in the huge amount of work at the start that is needed.

6 Reasons Why Mazda Won't Like Nissan's New Electric Sedan in China
Nissan launched its $17,000 N7 electric sedan in China on April 28, and the model has already received over 20,000 orders. In May, Nissan delivered 3,034 N7s in China, while the Mazda EZ-6, a competing electric sedan starting at $19,600, sold 1,821 units. Nissan confirmed that the N7 will expand to global markets, but hasn't yet specified which countries. While the N7 and the EZ-6 didn't sell as many units in May as models like Toyota's new bZ3X electric SUV, the two vehicles are helping deliver the value that Chinese consumers are looking for in an electric sedan, and Nissan has Mazda beat beyond price. Both models are comparable in size, with the N7 measuring 194 inches in length and 74.6 inches in width, and the EZ-6 measuring 193.7 inches in length and 74.6 inches in width. The N7 offers two motor options with 215 and 268 horsepower, respectively, while the EZ-6's electric powertrain delivers 258 horsepower. An EZ-6 gets you from 0-62 MPH in 6.2 seconds, and the 268-horsepower N7 isn't far behind at 6.9 seconds. While Mazda offers an extended-range electric vehicle (EREV) EZ-6 that's fundamentally an electric car, this version also features a 1.5-liter gas engine used as a battery recharging generator, so we'll focus on the EV version. Regarding range, the N7's two lithium-iron-phosphate (LFP) battery options-58 kWh and 73 kWh-yield 335 miles and 388 miles of range, respectively. Mazda's fully electric EZ-6 offers a 373-mile range. You'll pay $19,200 to $20,800 for a 73 kWh N7 in China, placing it neck and neck with the EZ-6 in terms of pricing. Those prioritizing charging speed will favor the N7, which charges from 10% to 80% in 19 minutes, three minutes faster than the EZ-6. Inside, Nissan's N7 contains a 15.6-inch center console display, while the EX-6 features a 14.6-inch infotainment screen. You'll also get more trunk space within an N7 at 17.8 cu ft compared to this Mazda's 12.3 cu ft. The EX-6 offers a bit more curb appeal than the N7 with a sportier look, but the N7's exterior seems to mirror the modern, minimalist EV design sentiment that consumers are after from brands like Tesla. While Nissan hasn't yet confirmed which markets the N7 will first expand to, Japan and Australia are rumored to be frontrunners, according to Carscoops. Other possibilities include Malaysia and limited European markets. In 45 days, Nissan has moved 10,000 N7 units, indicating promising growth from May's 3,034 deliveries. Nissan has historically experienced struggles in the Chinese and American EV markets, so the N7's early momentum is a bigger win for the automaker than it may seem. Drivers in the U.S. can also look forward to Nissan's redesigned Leaf SUV that's debuting in the fall. The 2026 Leaf is expected to cost more than the N7, with an unconfirmed starting price in the mid-$30,000s, but it remains more accessible than many electric SUVs in its class.

Tesla's Q2 Deliveries Were Not as Bad as Feared. Does That Mean You Should Buy TSLA Stock?
Tesla (TSLA) released its Q2 deliveries and production numbers on Wednesday, July 2. The deliveries, which closely approximate vehicle sales fell 13.5% year-over-year. The decline was higher than the 13% fall in Q1 and was the worst ever for the company. Tesla's Q2 deliveries came in at 384,122, which, while below the consensus estimate of 387,000, was better than what many were expecting. For instance, Troy Teslike, who claims to have an average error rate of just 3% in the preceding 12 quarters, put his final estimate at 356,000 on July 1.

However, Tesla's deliveries were not as bad as many, including me, were expecting. That said, with Tesla facing tougher comps in Q3, the prospects of the Elon Musk-run company posting yearly growth in deliveries look quite bleak. This would mean a second straight year of yearly decline for the company whose CEO once touted a long-term delivery compound annual growth rate of 50%, a goal it has virtually abandoned. Tesla also looks set to lose its crown as the world's largest electric vehicle seller. Chinese rival BYD (BYDDY) sold over 300,000 more EVs in the first half despite the first quarter being seasonally weak in China, its biggest market. The gap might be too big for Tesla to fill in the back half of the year, especially as BYD's global sales continue to soar, coming in at a record high in all months this year. Tesla's Energy business, which Musk once claimed would be bigger than the automotive business, is also sagging. It deployed 9.6 GWh of energy storage products in the second quarter, which was slightly below the 10.4 GWh it deployed in the first quarter, even as it rose just over 2% on a yearly basis. The number peaked at 11 GWh in Q4 2024 and has since fallen for two consecutive quarters. Overall, with markets expecting much worse numbers from Tesla, the Q2 delivery numbers provided a sigh of relief, and TSLA stock rose nearly 5% on Wednesday. The next big event for Tesla is the upcoming Q2 earnings, where the company might update its 2025 delivery guidance and also provide an update on the long-awaited low-cost model, which is expected to drive sales. Meanwhile, amid the slowdown in the automotive business, Tesla (and analysts bullish on the company) have been instead fixated on other aspects of the business. These include autonomous driving and robotaxis in the short to medium term, and robotics over the long term. To its credit, Tesla did launch the robotaxi service in Austin on June 22. While it wasn't a perfect launch and videos showed the vehicles breaking traffic laws, inviting an investigation from the National Highway Traffic Safety Administration (NHTSA), it was nonetheless an incremental step forward for the company. President Donald Trump's policies were never expected to be pro-electric vehicles (EVs), and EV tax credits now officially seem on their way out. However, his administration previously relaxed crash reporting requirements, which were supportive of autonomous driving and robotaxis. That, however, was in a different era in which Musk was a close ally of Trump. The political stakes are particularly high for its autonomous driving business. For instance, shortly before Tesla's robotaxi launch in the state, Texas Governor Greg Abbott signed legislation that effectively gives the state arbitrary powers to revoke the permits of autonomous vehicle operators that are deemed a threat to public safety. Given the feud between Musk and Trump, it wouldn't be surprising to see the company's robotaxi operations – which it plans to expand significantly in the coming months – face greater regulatory scrutiny. Overall, there is still a lot of uncertainty surrounding Tesla, and while the stock could still be a long-term winner if autonomous driving and humanoid operations go as planned, for now, I will refrain from adding to my position in the stock.
