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.

FAQ

What makes Groq's AI inference faster than GPUs?
Groq uses custom-built Language Processing Units (LPUs) with a Tensor Streaming Architecture and on-chip SRAM. This design significantly reduces memory access latency, allowing LPUs to deliver AI inference speeds 3-10 times faster than GPUs, achieving sub-100ms time to first token.
How much does it cost to use Groq's API?
Groq offers a pay-as-you-go token-based pricing model, with a generous free tier for prototyping. Paid tiers vary by model and context length, ranging from approximately $0.05 input / $0.08 output per million tokens for smaller models, up to $0.99 per million output tokens for larger models. Text-to-Speech and Automatic Speech Recognition have separate rates.
Can Groq be used for training large language models?
No, Groq's Language Processing Units (LPUs) are specifically designed for AI inference, which is the process of running trained models to generate responses. They are not built for training or fine-tuning large language models; those tasks still require traditional GPU hardware.
What types of AI models does Groq support?
Groq supports popular open-source large language models such as Llama 2, Llama 3, Mixtral, Qwen, and DeepSeek R1 Distill. Its API is compatible with OpenAI standards, allowing for integration into existing AI workflows for chat completions, audio transcription, and text-to-speech.
