What it looks like in real businesses
Four chats from real industries, all using Cerebras (llama3.3-70b) inside ChatMitra. Mix of English, Hindi, and Hinglish — the way customers actually type.
The most-recommended free-tier provider on ChatMitra for indie developers and weekend projects.
In simple terms: Cerebras is Groq's main competitor on raw inference speed — and they offer the most generous free tier on the market: 1M tokens / day, no credit card. If your customers wait for replies, Cerebras eliminates the wait.
Not 100% sure Cerebras is right for you?
That's okay — you can switch any time inside ChatMitra. Quick orientation:
- • If cost is your main concern, Groq or DeepSeek are worth a look
- • If top-shelf quality matters more, OpenAI or Anthropic are the usual picks
- • If you want balance, Gemini sits well in the middle
Still unsure? Start with Cerebras — switching later is one click inside ChatMitra without rebuilding your bot.
What is Cerebras, really?
If speed and cost matter more than polish, Cerebras is one of two providers that matter (the other is Groq). Replies arrive in milliseconds — by the time a customer finishes typing the next question, the previous reply is already on their screen.
Cerebras is a US AI compute company founded in 2015. Their wafer-scale chips run open-source models like Llama 3.3, Qwen3, and GPT-OSS at 2,600+ tokens / second — world-record speeds in independent benchmarks.

Best for these businesses
Pick Cerebras when you want Groq's speed AND a more generous free tier. Especially great for prototyping and weekend launches.
- Indie developers and small teams testing AI chatbots without budget
- High-volume D2C / kirana with mostly short queries (free 8K context cap is plenty)
- Festival sale weeks when a free 1M tokens / day covers genuine traffic
- Long conversation contexts on the free tier (8K context cap)
- Closed-flagship-quality replies — open models still trail GPT-5 / Claude on hardest queries
Cerebras's free tier is real and useful, but the 8K context cap means once a conversation hits ~30 messages, you'll start losing earlier context. For longer conversations, upgrade to the Developer tier (still cheap) or fall back to a larger-context provider.
How to get your Cerebras API key
Whole flow takes about 5 minutes. Mockups below are deliberately generic — Cerebras's dashboard may look slightly different by the time you read this, but the steps stay roughly the same.
1. Create your Cerebras account
Sign up using your business email. If you already have a Cerebras login (or a parent-product login), the same one usually works.
cloud.cerebras.ai/2. Verify your email & claim free credits
Cerebras drops you a free-tier credit (or rate-limit allowance) the moment you verify. That's enough for the first several thousand chats.
3. Open the API keys section
In the dashboard sidebar (or your profile menu), find "API keys". Click into it.
cloud.cerebras.ai/platform/api-keys4. Create a new secret key
Click "Create new key", give it a name like "ChatMitra production". Copy the key the moment it appears — most providers won't show it again.
5. Paste it into ChatMitra
Inside the AI Chatbot wizard (Step 2 — Pick your AI), select Cerebras, paste the key. ChatMitra validates it on the spot. Green tick = ready.
UI may change slightly as Cerebras updates their dashboard. The flow stays roughly the same — sign up, add a payment method (if needed), find the API keys section, create a key, copy it.
Set up Cerebras in ChatMitra (about 5 minutes)
Once you've copied your API key from Cerebras, the rest happens inside ChatMitra. Same wizard you'd use for any other provider — just pre-filled for Cerebras.
Pick Cerebras as your AI
In the ChatMitra AI Chatbot wizard, Step 2 shows the provider grid. Click Cerebras's tile, paste the API key you just copied. ChatMitra checks the key right then — green tick = ready.
Cerebras SelectedPick a model
ChatMitra auto-selects llama3.3-70b as the default — that's our pick for everyday WhatsApp business chat. You can override if you want a different one.
Write the bot's personality
Tell ChatMitra about your business — name, industry, a one-line description. Then write the personality prompt yourself, or click Generate with AI and tweak the draft. Cerebras reads this prompt before every reply.
Add a fallback (optional, recommended)
Add up to 3 backup providers. If Cerebras rate-limits or has an outage, ChatMitra automatically switches to the backup — your customers don't see an error. Most teams add one of Groq or Fireworks here.
Test, then activate
Built-in chat simulator lets you message your bot before any real customer does. Try a tricky question. When it looks right, hit Activate — and the bot starts answering on the WhatsApp number you've already connected to ChatMitra.
Worried about getting locked in? You can change AI providers any time inside ChatMitra. The bot's personality, conversation history, and customer data stay exactly where they are — only the underlying AI changes. Try Cerebras first, switch later if something better fits.

Frequently Asked Questions
Is Cerebras's 1M-tokens/day free tier really free?
Yes — 1,000,000 tokens / day free, no credit card. Within the rate limits (30 RPM, 60K-100K TPM, 8K context cap), this is genuinely usable for production. Many small ChatMitra stores never leave the free tier.
How does Cerebras compare to Groq on speed?
Both are world-class. Cerebras's 2,600+ TPS on Llama 3.3 70B is the published world record; Groq's 300+ TPS is also outstanding. In practice, both feel instant. Pick Cerebras if you specifically want the larger free tier.
Which Cerebras model should I pick?
Llama 3.3 70B is the right default — best balance of quality and speed. Llama 3.1 8B is for ultra-routine queries. Qwen3 32B if you're testing Chinese models. GPT-OSS 120B if you want OpenAI's open-source model.
How much does a Cerebras WhatsApp chatbot cost?
Many ChatMitra small stores pay ₹0 — they stay inside the 1M-tokens/day free tier. On the Developer tier, expect ₹400–₹2,500 / month for a typical busy store doing 1,000–10,000 chats.
Does Cerebras handle Hindi?
Through Llama 3.3 70B, yes — decently. Hindi and Hinglish work, regional dialects are weaker. Test before committing.
