Groq¶

What it is¶

Groq is an AI infrastructure company that developed the Language Processing Unit (LPU), a new type of processor designed specifically for the extreme high-speed requirements of LLMs. As of July 2026, Groq is the industry benchmark for low-latency inference, supporting Llama 4 Maverick, Mixtral 10x22B, and the newly released Gemma 3 models.

What problem it solves¶

Solves the "bottleneck" of slow LLM inference, providing near-instantaneous responses that enable real-time applications and highly interactive agents. It eliminates the latency hurdles that often hinder complex agentic workflows, particularly those utilizing the MCP 3.0 Task Protocol for multi-step reasoning.

Where it fits in the stack¶

Inference Provider / Infrastructure. It provides a high-speed API for the most popular open-source models (Llama, Mixtral, Gemma).

Typical use cases¶

Real-time Agents: Voice assistants or interactive chatbots that require sub-second response times.
High-Volume Processing: Summarizing or analyzing large quantities of text at hundreds of tokens per second.
Interactive Coding: Powering coding assistants where immediate, fluid feedback is essential.
Autonomous Task Execution: Serving as the fast inference backend for agents executing complex tasks via MCP 3.0.

Strengths¶

Extreme Speed: Often 10x+ faster than traditional GPU-based providers (400-800+ tokens/sec).
Open Model Support: Focuses on the best open-weights models like Llama 4 and Gemma 3.
Low Latency: Unmatched time-to-first-token (TTFT) and overall throughput.
LPU Efficiency: Unlike GPUs which excel at parallel pixel processing, LPUs are optimized for the serial nature of text generation, eliminating the "memory wall" that slows down standard hardware.

Limitations¶

Model Selection: Limited to the open models they have specifically optimized for their LPU hardware.
Context Window: Historically had smaller context windows than cloud giants, though this is expanding rapidly in 2026 to support 128k+ across most models.

When to use it¶

When response speed is the absolute top priority.
For "agentic" workflows where an agent makes many sequential, recursive LLM calls.
When using Llama or Mistral models and looking for the fastest possible user experience.

When not to use it¶

If you need proprietary models like GPT-4, GPT-5.5, or Claude 4.8.
For extremely large context tasks (e.g., 1M+ tokens) where native large-context models like Gemini are superior.

Getting started¶

Install the SDK:

pip install groq

Basic API call (Python):

from groq import Groq

client = Groq()

chat_completion = client.chat.completions.create(
    messages=[{"role": "user", "content": "Explain LPU speed with Gemma 3."}],
    model="gemma-3-27b",
)
print(chat_completion.choices[0].message.content)

CLI examples¶

# Query a model directly using the Groq API via curl
curl -X POST "https://api.groq.com/openai/v1/chat/completions" \
     -H "Authorization: Bearer $GROQ_API_KEY" \
     -d '{"model": "llama-4-70b", "messages": [{"role": "user", "content": "Hello"}]}'

# List available models via API
curl https://api.groq.com/openai/v1/models \
     -H "Authorization: Bearer $GROQ_API_KEY"

API examples¶

Groq enables exceptionally fluid streaming responses using the OpenAI-compatible SDK.

from groq import Groq

client = Groq()

stream = client.chat.completions.create(
    messages=[{"role": "user", "content": "Write a 500-word story."}],
    model="llama-4-70b",
    stream=True,
)

for chunk in stream:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="", flush=True)
