Back in 2016, Jonathan Ross founded Groq, the AI chip startup, which went on to enter a non-exclusive licensing agreement with NVIDIA for Groq’s inference technology (as part of a $20 billion deal). The name ‘Groq’ is commonly confused with X (formerly Twitter)’s Grok, which was launched in 2023 as a Gen AI chatbot. 

As demand for real-time AI continues to grow, inference has become one of the most important and expensive parts of the machine learning lifecycle. This has led to increased interest in alternative hardware architectures designed specifically to serve models efficiently at scale.

But what exactly is Groq? If companies like NVIDIA already dominate the GPU market, why do new approaches to inference hardware exist?

In this blog, we’ll explore what Groq is, why it was built, the problem it aims to solve, and how it compares to traditional GPUs.

What is inference?

AI inference is the process of applying or exposing a pre-trained model to new data in order to make new predictions, classifications, or decisions. A good example of inference is a model trained for spam detection being exposed to real-world data, such as your inbox. Inference occurs when the model makes a classification about whether the email is spam or not.

In other words, you can think of inference as throwing a model into the wild, wild being the real world, and observing the conclusions it makes based on the data that was used to train it.

​What makes inference important is its proximity to our daily lives. As more companies push to integrate “AI experiences” into their products, inference becomes important for powering these experiences, as each company has a unique data set that fuels the experience.

What is Groq?

Groq is an AI chip company founded in 2016 by Jonathan Ross, who, before founding Groq, began what became Google's TPU effort as a 20% project, where he designed and implemented the core elements of the original chip. 

If you are unfamiliar with the TPU (Tensor Processing Unit), it’s a custom chip that Google built specifically to handle machine learning workloads. TPUs became widely adopted within Google for machine learning workloads and now power many of its internal AI systems.

Introducing the LPU

Groq's flagship product is the LPU, or Language Processing Unit. The LPU features a functionally sliced microarchitecture, where memory units are interleaved with vector and matrix computation units. In simpler terms, where a GPU is designed to handle many types of workloads, graphics, training, and inference, the LPU is built to do one thing: run inference as fast as possible with predictable performance. This focus on inference speed is what makes the LPU Groq's moat; it is one of the fastest architectures for low-latency language model inference in specific workloads.

FeatureDescription

Single core & on-chip SRAM

Hundreds of MB of SRAM store model weights directly (not cache), reducing latency and keeping compute units fully utilized

Custom compiler, fully in control

Static scheduling enables deterministic, predictable performance at any scale

Power efficient

Air-cooled design reduces infrastructure complexity, lowering cost and environmental impact

Direct chip-to-chip connectivity

LPUs connect via a plesiosynchronous protocol, allowing hundreds of chips to operate as a coordinated system with compiler-managed data flow

NVIDIA’s deal with Groq

In December 2025, NVIDIA agreed to purchase assets from Groq for approximately $20 billion, which is a record for NVIDIA. As part of the deal, Groq founder Jonathan Ross and president Sunny Madra joined NVIDIA to help scale the licensed technology. Groq continues to operate as an independent company with Simon Edwards stepping into the role of CEO, and GroqCloud remains up and running.

Why did NVIDIA invest in Groq?

While it may seem like a move to eliminate competition, NVIDIA’s interest in Groq is better understood as a strategic expansion of its inference capabilities. NVIDIA continues to dominate AI training, but inference is an increasingly competitive space, particularly as hyperscalers develop their own internal solutions.

Groq’s LPU represents a different architectural approach, optimized for low-latency, deterministic inference. Integrating this kind of technology allows NVIDIA to broaden its offering without having to build a new inference-first architecture from scratch.

This aligns with NVIDIA’s broader push to make inference faster and more cost-efficient. Recent platform developments, including next-generation CPU and GPU designs tailored for modern AI workloads, reflect that same direction. Bringing in specialized inference technology complements, rather than replaces, those efforts.

But what does this mean for GPUs?

GPUs vs. Groq: What is the difference?

Groq’s approach does not signal the end of GPUs for inference. Instead, it highlights that different hardware is optimized for different stages of the AI lifecycle. As general-purpose accelerators, they provide the flexibility needed to take models from development to production.

Groq’s LPUs, by contrast, are purpose-built for serving models that are already trained. Their strength lies in real-time, latency-sensitive workloads, where predictable performance matters more than raw parallel throughput. This makes them well-suited for applications like chatbots, agents, and other interactive AI systems.

It’s also worth noting that building an inference platform in-house requires significant expertise and time. Platforms like GroqCloud simplify this by providing access to specialized inference hardware without the overhead of managing infrastructure.

In practice, the two are complementary: GPUs handle training and broad workloads, while LPUs optimize how models are served at scale.

Improves utilization by processing multiple requests simultaneously (batching). This increases throughput but can introduce latency

Cost considerations

More efficient at low-latency, real-time workloads

More cost-efficient at high throughput (batched workloads)

Summary

NVIDIA's move to bring Groq into the fold signals just how important inference is becoming in the AI landscape. As models get smarter and reasoning chains get longer, the demand for faster and cheaper inference is only going to grow.

In this blog, we looked at what Groq is, why NVIDIA acquired it, and how LPUs differ from traditional GPUs when serving trained models.
