This year’s GTC keynote focused on one important idea: By co-designing, leveraging open models, and collaborating with all supply chain partners, Nvidia provides the most efficient system to pave the way for future AI that no other competitor does.
The overarching logic of this year’s keynote is that NVIDIA provides the infrastructure for the modern economy. NVIDIA CEO Jensen Huang no longer just sells the chips; he is telling the audience that NVIDIA is capturing all five layers of the cake:
“NVIDIA is a vertically integrated computing company with open horizontal integration with the world.”
By capturing "100% of the $100 trillion of industry" represented by the companies at GTC, Jensen Huang ensures that its architecture is the foundation for all future AI, whether digital agents or physical robots.
1. The “Flywheel” of the Installed Base
The most significant barrier to entry for competitors is NVIDIA’s massive, existing user base.
The Installed Base Advantage: Huang emphasized that hundreds of millions of CUDA-compatible GPUs are already on the market. This creates a “gravity” that pulls developers in.
The Developer Cycle: Because so many people own NVIDIA hardware, developers first write their most innovative algorithms in CUDA. This leads to more applications, which in turn attract more users, further expanding the base.
Extended Life Cycles: By providing constant software updates that improve the performance of older chips (like the Ampere architecture), NVIDIA ensures that its ecosystem remains the industry standard long after the initial hardware purchase.
The Role of Groq: The “Inference King”
Screen snapshot NVIDIA’s core argument is that while training is a one-time, compute-heavy task, inference is an ongoing industrial process. Huang described this through the concept of “AI Factories”: facilities that take in electricity and “unstructured data” (like raw video or text) and output “tokens” (intelligence and actions) that generate revenue.
A major highlight of the keynote was the integration of Groq technology into the NVIDIA ecosystem. Following a $20 billion transaction in late 2025, NVIDIA unveiled the Groq 3 LPU (Language Processing Unit) as a specialized engine for the “decode” phase of AI.
Screen snapshot Why Groq matters for NVIDIA’s edge:
Speed (Low Latency): While traditional GPUs are excellent at “prefill” (understanding the initial prompt), Groq’s LPU architecture is optimized for “decode”—the part where the AI actually spits out words one by one. Huang claimed this specialized hardware can generate tokens 35 times faster than previous systems.
Predictability: Unlike standard chips that might “jitter” or slow down under heavy use, Groq’s architecture is deterministic. This means it provides a smooth, lightning-fast response every time, which is critical for Autonomous Agents that need to act instantly.
The “Heterogeneous” Strategy: In the new Vera Rubin systems, NVIDIA uses its own GPUs to handle the heavy reasoning and Groq’s LPUs to handle the high-speed delivery of answers. This combined “Inference Pipeline” allows NVIDIA to dominate the economics of running AI, making it cheaper and faster for companies to deploy large-scale agents.
Screen snapshot Why this gives NVIDIA a Competitive Edge
By incorporating Groq, NVIDIA has addressed the growing demand for cheaper, leaner inference hardware. Instead of letting startups or competitors like Groq eat into the inference market, NVIDIA absorbed the technology to offer a “full-stack” solution.
This means a customer can buy a single Vera Rubin rack that handles the training, the complex reasoning, and the lightning-fast delivery of answers—all within the same “AI Factory” architecture.

Professor Shih-hao Hung of National Taiwan University, Department of Computer Science and Information Engineering, commented:
Nvidia has now released the technical details and application examples of Groq 3 LPX. As we had expected, it is mainly designed for ultra-high-speed inference. If a task involves very complex problems that require extremely long reasoning processes (i.e., many reasoning tokens), this system can be much faster than other architectures, provided that most of the model parameters and KV cache reside in SRAM.
To put things into perspective, a single LPX rack contains 256 chips, each equipped with 0.5 GB of SRAM. Through high-speed networking inside the rack, the chips can be interconnected for parallel computing. Even so, the total SRAM capacity is only 128 GB. While this is not enough to fit very large models, mid-sized models running extremely fast complex reasoning could, in certain domains, be more useful than large models. In that sense, the system can be seen as a niche product.
Interestingly, Nvidia is not satisfied with that alone. It has applied several well-known acceleration techniques—including speculative decoding and prefill–decode disaggregation—and uses the LPX rack as an accelerator for mainstream GPU racks running large models. This is something the Groq team could not achieve when they were competing directly with Nvidia, and it highlights one of the advantages of collaboration.
As for how much acceleration this approach actually delivers, Nvidia’s official white paper can serve as a reference—but it should not be taken at face value. Meaningful performance estimates require incorporating the characteristics of real-world workloads as well as the specific features of the computing platform.
2. The Five-Layer “AI Factory” Stack
NVIDIA is positioning itself as more than a chip designer; it is a full-stack “platform company.” Huang outlined a “five-layer cake” that provides a complete industrial solution:
Infrastructure: The physical space and power.
Chips: High-performance hardware like Blackwell, Vera, and Rubin.
Platforms: Software environments like CUDA X and the new “AI Factories.”
Models: Integration with both proprietary and open-source models.
Applications: The end-user tools that “turn power into revenue.”
By controlling every layer, NVIDIA can optimize the interaction between software and silicon in a way that “point-solution” competitors (who only make chips or only make software) cannot.
3. Scaling Laws and Generative Compute
Huang argued that the industry has moved past the era of “retrieving” data to “generating” it.
Generating with Compute: When data is missing, NVIDIA’s strategy is to “generate more with compute.” This relies on their hardware’s ability to handle massive scaling laws—where more compute power leads to exponentially better AI performance.
Economic Moat: New technologies like Vera are claimed to operate at 35 times less the cost than previous generations. By drastically lowering the “cost per token,” NVIDIA makes it financially impractical for companies to switch to less efficient architectures.
4. Transition to “Physical AI” and Autonomous Agents
The keynote suggests NVIDIA is already moving to the next battlefield: the “Industrial Age” of AI.
Autonomy: Shifting from passive AI agents to those that “act autonomously” using the Nemo framework for safety and guardrails.
Robotics: Huang described this as the “GPT moment for the bots,” where AI moves from digital screens into physical machines (Physical AI). By building the simulation and training platforms for these robots now, NVIDIA is securing its edge in the next decade of industrial automation.
Conclusion: The Inevitability of the Ecosystem
The true takeaway from this year’s GTC is that NVIDIA is no longer just selling hardware; it is selling a closed-loop economic engine. By integrating Groq’s high-speed inference into the Vera Rubin architecture, Jensen Huang has effectively neutralized the “point-solution” competitors who hoped to challenge NVIDIA on speed or cost-per-token alone.
As Professor Shih-hao Hung noted, the real magic isn’t just in the specialized hardware, but in the collaboration—using speculative decoding and disaggregated prefill-decode to turn niche performance into mainstream acceleration. This is the hallmark of the NVIDIA strategy: identifying a breakthrough, absorbing it into the stack, and making it a standard part of the “five-layer cake.”
By the end of the keynote, the roadmap became clear. We are moving from a world where we “search and retrieve” to one where we “compute and generate.” Whether it is a digital agent navigating a complex reasoning task or a physical robot navigating a factory floor, they will likely be doing so on NVIDIA’s foundation. In the race to build the infrastructure for the modern economy, Huang isn’t just leading the pack—he is building the track.

Your framing of the Groq acquisition as NVIDIA's answer to the inference economics problem is sharp. The $20 billion price tag looks steep until you consider what it actually buys: a dedicated decode engine that eliminates the HBM bottleneck entirely by running on SRAM. That's not just a performance upgrade — it's a fundamentally different cost curve for inference at scale. The real strategic insight here is that NVIDIA is building a heterogeneous compute stack where training and inference are no longer forced through the same silicon. Every hyperscaler writing nine-figure checks to NVIDIA is simultaneously exploring custom chips for exactly this reason — Jensen's counter-move is to own both sides of that split before customers build their own alternatives.
