Luma AI Unveils Ray3 Modify: Redefining Video Transformation

Innovative AI Model Transforms Video Editing

Luma AI, the a16z-backed leader in AI video and 3D modeling technology, has introduced its latest innovation, Ray3 Modify. This groundbreaking model allows creators to modify existing footage by using character reference images that faithfully preserve the original performance. By specifying start and end frames, users can seamlessly generate transitional footage, elevating the creative process.

Preserving Authentic Performance

Ray3 Modify addresses a critical challenge in visual production: maintaining the integrity of human performance amidst digital transformation. According to Luma AI, the model ensures that key elements—such as motion, timing, eye line, and emotional delivery—are retained, enabling creative studios to incorporate human actors within AI-modified scenarios. This capability is essential for studios aiming to produce consistent and high-quality brand or creative content.

Expanding Creative Possibilities

Beyond preserving performance, Ray3 Modify empowers creators by facilitating detailed character transformations. Users may provide a reference image to transform an actor’s appearance, retaining crucial details like costumes, likeness, and identity across the shoot. Additionally, by offering start and end frames, directors can meticulously control transitions and character behavior, ensuring smooth continuity between scenes.

Strategic Industry Implications and Funding Momentum

In a statement, Amit Jain, co-founder and CEO of Luma AI, emphasized that the development of generative video models has historically been challenged by issues of control. “Generative video models are incredibly expressive but also hard to control. Today, we are excited to introduce Ray3 Modify that blends the real-world with the expressivity of AI while giving full control to creatives,” Jain explained. The model is now available via the company’s Dream Machine platform.

This release follows significant market developments, including Luma AI’s recent funding surge. A fresh $900 million funding round, led by Saudi Arabia’s Humain and witnessed by investors such as a16z, Amplify Partners, and Matrix Partners, underscores the high stakes in the AI-driven visual content arena. Furthermore, Luma AI’s strategic plans include building a 2GW AI cluster in Saudi Arabia, reinforcing its commitment to expanding technological capabilities and market reach.

Conclusion

With Ray3 Modify, Luma AI is setting a new benchmark in the integration of AI with video production. By offering unprecedented control over digital transformations without compromising on performance authenticity, the new model positions the company at the forefront of an industry undergoing rapid evolution.

China’s Humanoid Robot Boom Faces A Bigger Question: Can These Machines Make Money?

Unitree’s $9 Billion Bet On The Future Of Robotics

China’s humanoid robotics industry is attracting huge investor interest, but as Unitree Robotics prepares for its public debut, questions are growing over whether its robots can move beyond impressive acrobatics and become commercially viable tools.

The Hangzhou-based startup priced its IPO at 150.8 yuan ($22.4) per share, raising $900 million and valuing the company at 61 billion yuan, or about $9 billion. The offering attracted record retail demand on Shanghai’s STAR Market, with the online tranche oversubscribed more than 5,000 times and a winning rate of just 0.018%. Strategic investors included AI startup DeepSeek.

A Unitree-linked pre-IPO perpetual contract was trading at roughly four times the IPO price on Friday, highlighting the speculative interest surrounding the company.

Unitree is known for robots capable of kung fu kicks, backflips and recovering from falls. Yet analysts question whether the technology is ready for large-scale commercial use. “For these humanoid robots, to be honest, they’re fascinating. They can dance and all that, but I’ve never seen them doing any real housework,” said Hao Hong, managing partner of Lotus Asset Management.

In its prospectus, Unitree warned that mass adoption could take longer than expected because robotic hands are still not precise or durable enough for sustained use.

From Acrobatic Robots To Commercial Machines

Even advanced humanoid robots can currently perform only a limited number of tasks and typically operate for a few hours before recharging, according to Dominik Pross, an equity analyst at VP Bank. Most models run for up to four hours, while robots also need to be trained for individual tasks.

“Robots have to be specifically trained for each and every task entrusted to them, even the simplest,” Pross said.

More robotics listings are expected, with Unitree rivals AgiBot and Leju Robotics seeking listings in Hong Kong and Shenzhen. LimX Dynamics founder Will Zhang said last month that “listing is a must.”

China’s Cost Advantage

China’s manufacturing scale has helped it establish a leading position in robotics. Wood Mackenzie expects the global humanoid robot fleet to surpass 10 million units by 2035, while China already accounts for more than 70% of global industrial robot installations and nearly 90% of humanoids deployed last year.

Average humanoid robot prices fell 93% between 2020 and 2025 to $58,000. Unitree’s flagship G1 costs $16,000, while SemiAnalysis estimates that the company has cut the price of its G1 EDU model by more than 45% to $27,300, while maintaining a 67% gross margin.

Falling prices and government support are attracting investment, but analysts say it will take time to prove that humanoid robots can generate strong returns. Unitree’s revenue more than quadrupled last year, although adjusted first-quarter profit fell more than 52% as research and development and marketing spending increased. Nearly three-quarters of its humanoid revenue in the first nine months of 2025 came from research and education, highlighting the gap between demonstrations and widespread commercial use.

“Unlike many early-stage robotics companies, the Unitree story is backed by real revenue growth,” said Jeff Ko, chief analyst at CoinEx. Still, he noted that its $9 billion valuation, at more than 200 times last year’s earnings, reflects significant speculative interest.

Geopolitical Risks

Unitree’s IPO momentum has continued despite growing pressure on Chinese robotics companies. The U.S. moved last month to ban imports of foreign-made humanoid and four-legged robots, potentially exposing Unitree, which generated about 13% of its revenue from the U.S. last year.

Access to Nvidia hardware and software is another risk, as Chinese robotics companies rely on the technology to power their systems. “Chinese robot producers are not yet in a position to do without Western components completely,” Pross said.

China’s control over rare earths used in robot actuators and motors could nevertheless give its manufacturers an advantage, according to Bernstein analyst Dien Wang.

The Bigger Robotics Opportunity

The potential market is attracting major players, including Tesla, whose CEO Elon Musk is expanding production plans for Optimus humanoid robots. At the same time, some researchers argue that the future of robotics will not be limited to humanoids: quadruped and purpose-built robots can be cheaper and more reliable for repetitive industrial tasks, while humanoids may be better suited to unpredictable environments.

For Unitree, the challenge is no longer proving that its robots can perform impressive tricks. It is proving that they can do enough useful work to justify a $9 billion valuation.
