Groq provides an inference engine built on proprietary Language Processing Units (LPUs) designed to deliver ultra-fast, low-latency responses for large language models. By focusing on accelerating the inference phase, it eliminates the delays that hinder real-time AI applications.

## LPU Chips Delivering 750+ Tokens per Second

Groq’s core innovation lies in its custom-built Language Processing Units (LPUs). These Application-Specific Integrated Circuits (ASICs) feature a Tensor Streaming Architecture (TSA) and integrate hundreds of megabytes of on-chip SRAM. This design minimizes memory access latency, a common bottleneck for AI performance. The result is an architecture that ensures predictable and consistent execution times, crucial for real-time applications.

Groq offers an API, GroqCloud, that allows developers to integrate these high-speed AI capabilities into their applications. This API supports chat completions, audio transcription (speech-to-text), and text-to-speech, and can generate structured JSON from prompts.

### Real-Time Apps, Voice AI, and High-Throughput Workloads

Groq serves AI application developers, mid-to-large technology companies, hyperscale data centers, and independent developers. Its speed is particularly beneficial for use cases demanding near-instantaneous AI responses:

-   **Real-time Interactive AI**: Powering chatbots, virtual assistants, and co-pilots where immediate feedback is essential.
-   **Autonomous Systems**: Enabling fast, precise decision-making in vehicles and drones.
-   **Financial Analysis**: Accelerating real-time risk assessment, fraud detection, and market trend prediction.
-   **Content Generation & Processing**: Facilitating dynamic content delivery, real-time language translation, and rapid image/speech recognition.
-   **Gaming**: Enhancing AI gameplay with dynamic NPC behavior and interactive worlds.

## Llama 3.3 70B at 300+ T/s and Mixtral at 750+ T/s

Groq’s LPUs deliver impressive performance, often 3-10 times faster than GPUs, and up to 18 times faster than some cloud providers for LLM inference. They can achieve 300-500 tokens per second for models like Llama 2 70B, with a sub-100ms time to first token (TTFT). This performance also comes with efficiency; LPUs are designed to be energy-efficient, consuming less power and being up to 10x more energy-efficient for LLMs compared to GPUs, and are air-cooled.

Groq supports popular open-source LLMs, including Llama 2, Llama 3, Mixtral, Qwen, and DeepSeek R1 Distill. Its OpenAI-compatible API simplifies integration into existing AI workflows and supports various automation tools and LLM app development frameworks.

### Free Developer Tier, Pay-as-You-Go, and Enterprise

Groq operates on a pay-as-you-go token-based pricing model, with several options for users:

-   **Free Tier**: A generous free tier is available without a credit card, suitable for prototyping and testing. It includes rate limits such as 30 requests per minute and 6,000 tokens per minute for most models, with a daily cap of 14,400 requests.
-   **Developer Tier**: Accessible with a credit card, this tier provides up to 10x higher limits and a 25% discount on all tokens.
-   **Batch API**: Offers a 50% discount for non-urgent, large-scale requests.
-   Prompt Caching: Provides a 50% discount on input tokens for repetitive queries.

| Service | Price (per million tokens/characters/audio hour) |
| --- | --- |
| Llama 3.3 70B (input) | $0.59 |
| Llama 3.3 70B (output) | $0.79 |
| Gemma 2 9B (input) | $0.10 |
| Gemma 2 9B (output) | $0.10 |
| Whisper (speech-to-text) | $0.111/hour |
| PlayAI TTS (text-to-speech) | $0.30/1M chars |

## No Fine-Tuning, Limited Context, and Model Availability Gaps

Groq focuses exclusively on inference speed, which comes with trade-offs:

-   Inference Only: Groq doesn’t train models — it accelerates running existing ones. Teams needing training infrastructure must look elsewhere.
-   Model Selection: Only open-source models are supported (Llama, Mixtral, Qwen, DeepSeek R1 Distill). Proprietary models like GPT-4 or Claude aren’t available.
-   Free Tier Rate Limits: The free tier caps at 30 requests/minute, 6,000 tokens/minute, and 14,400 daily requests — tight for production use.
-   Hardware Scale: Scaling beyond prototype levels requires negotiating enterprise contracts; Groq’s LPU hardware isn’t available for self-hosting.
-   Evolving Ecosystem: As a relatively young platform, the API and feature set are still maturing compared to established cloud providers.
