At a high level, Groq operates a hybrid business model combining elements of semiconductors, cloud services, and on-premise enterprise deployments. However, their core product offering revolves around their custom AI accelerator chip, the Tensor Streaming Processor (TSP), optimized for ultra-low latency inference on large language models.

Groq's most visible revenue stream currently comes from GroqCloud, their cloud AI inference platform. GroqCloud provides access to Groq's massively parallel TSP infrastructure running the latest large language models like Llama and Mistral MixedRoll through a simple pay-as-you-go API. This operates similar to the Nvidia-hosted AI services from major cloud providers.

Groq charges extremely aggressive pricing on GroqCloud starting at $0.27 per million tokens generated. While likely unprofitable currently, this pricing helps drive adoption of their TSP chips by making it easy for developers to experiment and build apps/services on Groq's unique low-latency architecture.

The other side of Groq's business involves selling their TSP chips and servers directly to enterprises with large on-premise AI infrastructure needs. Given Groq's nascent stage, this revenue stream is likely still modest.

However, selling hardware deployments could become a bigger revenue driver over time as more organizations want the flexibility and data security of running large language models internally. Groq has announced on-prem deployments with entities like Saudi Aramco.

Similar to traditional semiconductor companies, Groq likely charges a upfront fee to purchase the TSP chips/servers, with potential for ongoing support/maintenance revenues.

Groq is up against three basic categories of competition: silicon incumbents, hyperscaler clouds, and other startups.

Even though more than 50 companies are making AI chips, the AI data center chip market is dominated by three companies, Nvidia ($390B), Intel ($123B), and AMD ($118B).

Nvidia used its GPUs, built primarily for gaming, to capture nearly 100% share of the AI training market early on, growing its market cap from $7B to $3.25T in less than ten years. However, Nvidia's GPU architecture seems to face some inherent limitations for ultra-low latency inference required for interactive AI applications.

The major public cloud providers all have active AI accelerator programs leveraging their hyperscale economics and co-design capabilities. Google has been deploying its Tensor Processing Units (TPUs) since 2015, while AWS recently released its Inferentia chip focused on inference. Microsoft has utilized FPGAs extensively and has its own pipeline of AI chips in development.

These cloud platforms can package their custom silicon into optimized "AI boxes" and leverage their distribution capabilities - potentially squeezing out current chip suppliers in 5-10 years if they achieve cost/performance leadership.

2021 alone saw AI chip startups raise over $10B in VC funding as investors piled into the next potential "arm" wave of novel AI architectures. Well-funded startups like Cerebras ($5B+ valuation) with its massive chip aimed at training, and Graphcore have gained traction at prominent research centers.

However, none have broken through to challenge Nvidia's dominance of the training market yet. For inference, Groq is taking an innovative architectural approach tailored for low-latency applications, but remains an emerging player with an unproven long-term business model.

Groq's proprietary low-latency architecture gives it differentiation versus Nvidia's CUDA ecosystem, but also diminishes its addressable market compared to accelerators optimized for throughput over latency. Sustaining long-term differentiation as larger competitors enhance their offerings will be critical for Groq to maintain a viable competitive positioning.

Groq's initial TAM is centered around the market for AI inference acceleration, with a specialized focus on latency-sensitive workloads like large language model deployment, conversational AI, and autonomous systems.

The size of the overall AI inference acceleration market was estimated at $12B in 2022 and has been projected to grow to $83B by 2027.

However, only a subset of these inference workloads are truly latency-sensitive enough to favor Groq's architecture over throughput-optimized accelerators

Based on industry analysis, we estimate Groq's immediately addressable inference acceleration TAM focused on extremely low-latency requirements is likely in the range of $3-5B but growing rapidly.

While starting in a niche, Groq has clear opportunities to expand its addressable market if it can extend its architectural advantages:

Planned moves to denser process nodes (e.g. 4nm roadmap) could improve chip economics to better compete on throughput and capture a wider range of inference use cases outside the latency niche.

Working directly with AI research labs and model developers, Groq could optimize future models and systems to take maximum advantage of their massively parallel/scaled-out architecture.

Novel applications like real-time AI agents, autonomous systems, coding assistants, etc. could drive demand for more interactive, latency-optimized AI compute.
