The AI world is evolving fast. While most companies deal with slow response times and performance issues, Cerebras is delivering incredible speed that’s transforming what we can do with large language models.

Why Speed Actually Matters in AI

Speed isn’t just a cool feature anymore—it’s essential for business success. According to Cerebras customer stories, their infrastructure delivers over 2,000 tokens per second. That’s more than 30 times faster than ChatGPT or Claude!

This isn’t just about getting faster answers. It’s about building entirely new types of AI applications that weren’t possible before.

Here’s what one customer from GSK said:

“With Cerebras’ inference speed, GSK is developing innovative AI applications, such as intelligent research agents, that will fundamentally improve the productivity of our researchers and drug discovery process.”

What Makes Cerebras Special?

Cerebras built something truly revolutionary—a wafer-scale engine designed specifically for AI workloads. While traditional GPU clusters struggle with communication delays and memory limits, Cerebras’ architecture provides:

• Unmatched throughput: Process thousands of tokens per second
• Ultra-low latency: Real-time interactions that feel natural
• Massive context windows: Handle complex, multi-step reasoning tasks
• Energy efficiency: Do more while using less power

What This Means for Developers

You can now build applications that:

• Process entire codebases in seconds instead of minutes
• Analyze genomic data in real-time for medical decisions
• Power enterprise search that feels instant
• Enable conversational AI that never interrupts your flow

Getting Started with Cerebras

The good news? Cerebras makes their enterprise-grade infrastructure surprisingly easy to use for developers. Let’s look at how you can integrate Cerebras-powered Llama models into your apps.

Note: These examples show common patterns. Check the Cerebras documentation for exact implementation details.

JavaScript/Node.js Example

Perfect for web apps and real-time interfaces:

// cerebras-llama-js.js
import { CerebrasClient } from '@cerebras/sdk';

// Initialize the client with your API key
const client = new CerebrasClient({
apiKey: process.env.CEREBRAS_API_KEY,
model: 'llama-3-70b',
});

async function generateResponse(prompt) {
try {
// Cerebras delivers results at lightning speed
const startTime = Date.now();

const response = await client.generate({
prompt: prompt,
maxTokens: 512,
temperature: 0.7,
topP: 0.9,
});

const endTime = Date.now();
const duration = endTime - startTime;
const tokensPerSec = response.usage.output_tokens / (duration / 1000);

console.log(`Response generated in ${duration}ms`);
console.log(`Tokens per second: ${tokensPerSec.toFixed(2)}`);

return response.text;
} catch (error) {
console.error('Error generating response:', error);
throw error;
}
}

// Example usage
const prompt = "Explain how Cerebras' wafer-scale architecture improves AI performance:";
generateResponse(prompt).then(console.log);

Rust Example

For performance-critical applications:

// cerebras_llama.rs
use cerebras_sdk::{Client, GenerateRequest, Model};
use std::time::Instant;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
// Initialize the Cerebras client
let client = Client::new(
&std::env::var("CEREBRAS_API_KEY")?,
Model::Llama3_70b,
);

let prompt = "Write a function that calculates Fibonacci numbers efficiently in Rust:";

// Measure the incredible speed
let start = Instant::now();

let request = GenerateRequest::new()
.prompt(prompt)
.max_tokens(256)
.temperature(0.3)
.top_p(0.95);

let response = client.generate(request).await?;

let duration = start.elapsed();
let tokens_per_second = response.output_tokens as f64 / duration.as_secs_f64();

println!("Response generated in {:.2?}", duration);
println!("Tokens per second: {:.2}", tokens_per_second);
println!("Result:\n{}", response.text);

Ok(())
}

Go Example

For cloud-native applications and microservices:

// cerebras_llama.go
package main

import (
"context"
"fmt"
"log"
"os"
"time"

"github.com/cerebras/go-sdk/client"
"github.com/cerebras/go-sdk/models"
)

func main() {
// Initialize Cerebras client
apiKey := os.Getenv("CEREBRAS_API_KEY")
if apiKey == "" {
log.Fatal("CEREBRAS_API_KEY environment variable is required")
}

cerebrasClient, err := client.NewClient(apiKey)
if err != nil {
log.Fatal("Failed to create client:", err)
}

// Define the prompt
prompt := `Analyze this Go code for potential performance optimizations:

package main

import "fmt"

func main() {
sum := 0
for i := 0; i < 1000000; i++ {
sum += i
}
fmt.Println(sum)
}`

// Measure performance
start := time.Now()

request := models.GenerateRequest{
Prompt:      prompt,
MaxTokens:   300,
Temperature: 0.2,
Model:       "llama-3-70b",
}

response, err := cerebrasClient.Generate(context.Background(), request)
if err != nil {
log.Fatal("Generation failed:", err)
}

duration := time.Since(start)
tokensPerSecond := float64(len(response.Tokens)) / duration.Seconds()

fmt.Printf("Response generated in %v\n", duration)
fmt.Printf("Tokens per second: %.2f\n", tokensPerSecond)
fmt.Printf("Analysis:\n%s\n", response.Text)
}

PHP Example

For web applications and enterprise integration:

<?php
// cerebras_llama.php
require 'vendor/autoload.php';

use Cerebras\Client;
use Cerebras\GenerateRequest;

// Initialize the Cerebras client
$client = new Client($_ENV['CEREBRAS_API_KEY'] ?? getenv('CEREBRAS_API_KEY'));

$prompt = "Generate a secure PHP login system with password hashing and session management:";

// Time the response
$startTime = microtime(true);

try {
$request = new GenerateRequest([
'prompt' => $prompt,
'model' => 'llama-3-70b',
'max_tokens' => 400,
'temperature' => 0.5,
'top_p' => 0.9,
]);

$response = $client->generate($request);

$endTime = microtime(true);
$duration = $endTime - $startTime;
$tokensPerSecond = count($response->tokens) / $duration;

echo "Response generated in " . number_format($duration, 4) . " seconds\n";
echo "Tokens per second: " . number_format($tokensPerSecond, 2) . "\n";
echo "Generated code:\n" . $response->text . "\n";

} catch (Exception $e) {
echo "Error: " . $e->getMessage() . "\n";
}
?>

What Makes Cerebras Different?

The speed difference isn’t just about better hardware—it’s about completely rethinking AI infrastructure.

While competitors use clusters of GPUs connected by slow interconnects, Cerebras built a single chip the size of a wafer with:

• 4 trillion transistors working together
• No communication bottlenecks between processing elements
• Memory bandwidth that eliminates data transfer delays
• Software stack optimized specifically for LLM workloads

This architecture enables real-world performance that’s simply unmatched. One customer noted:

“We have a cancer-drug response prediction model that’s running many hundreds of times faster on that chip (Cerebras) than it runs on a conventional GPU… We are doing in a few months what would normally take a drug development process years…”

Real-World Use Cases

1. Real-time Code Assistance

Developers using tools powered by Cerebras can stay “in flow” because the AI responds at the speed of thought. No more waiting and losing your train of thought.

2. Enterprise Search
