200+ open-source models hosted at competitive prices.
- No free tier
- Cost: Low
- Speed: Fast
- Best for: Open-model variety
It's a WhatsApp bot that runs on open-source models hosted by Together AI. With ChatMitra you bring your Together API key — setup takes about 5 minutes, and you get 200+ models from a single key.
What it looks like in real businesses
Four chats from real industries, all using Together AI (meta-llama/Llama-3.3-70B-Instruct-Turbo) inside ChatMitra. Mix of English, Hindi, and Hinglish — the way customers actually type.
Picked by ChatMitra customers who want open-model flexibility and one-key access to many alternatives.
In simple terms: Together AI is the open-model marketplace — pick from Llama 3.3, Mixtral, DeepSeek-R1, Qwen and more, all from a single API key. Pricing scales with model size, generally $0.05–$3.50 per 1M tokens.
Not 100% sure Together AI 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 Together AI — switching later is one click inside ChatMitra without rebuilding your bot.
What is Together AI, really?
Together AI doesn't make models — they host other people's open models faster and cheaper than the labs themselves often do. If you want to A/B test Llama vs Mistral vs Qwen without juggling 5 different API keys, this is the cleanest way.
Together AI is a US AI infrastructure company founded in 2022, known for hosting 200+ open-source models. Pricing varies by model size and family.

Best for these businesses
Pick Together AI when you want flexibility — multiple open-model options, one API key, predictable pricing.
- Teams that want to A/B test 2–3 different open models against each other
- Businesses comfortable with open-source models and want to avoid lock-in
- Use cases where you might want to fine-tune a hosted model later
- Closed flagship-quality replies (GPT-5, Claude, Gemini still have a quality edge)
- Free-tier-only experimentation — pricing kicks in fast
Open models like Llama 3.3 70B are excellent but still trail GPT-5 / Claude Sonnet on the hardest queries. For 90% of WhatsApp business chat, you won't notice the gap.
How to get your Together AI API key
Whole flow takes about 5 minutes. Mockups below are deliberately generic — Together AI's dashboard may look slightly different by the time you read this, but the steps stay roughly the same.
1. Create your Together AI account
Sign up using your business email. If you already have a Together AI login (or a parent-product login), the same one usually works.
api.together.ai/signup2. Verify your email & claim free credits
Together AI 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.
api.together.ai/settings/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 Together AI, paste the key. ChatMitra validates it on the spot. Green tick = ready.
UI may change slightly as Together AI 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 Together AI in ChatMitra (about 5 minutes)
Once you've copied your API key from Together AI, the rest happens inside ChatMitra. Same wizard you'd use for any other provider — just pre-filled for Together AI.
Pick Together AI as your AI
In the ChatMitra AI Chatbot wizard, Step 2 shows the provider grid. Click Together AI's tile, paste the API key you just copied. ChatMitra checks the key right then — green tick = ready.
Together AI SelectedPick a model
ChatMitra auto-selects meta-llama/Llama-3.3-70B-Instruct-Turbo 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. Together AI reads this prompt before every reply.
Add a fallback (optional, recommended)
Add up to 3 backup providers. If Together AI rate-limits or has an outage, ChatMitra automatically switches to the backup — your customers don't see an error. Most teams add one of Fireworks or Openrouter 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 Together AI first, switch later if something better fits.

Which Together AI model should I pick?
Llama 3.3 70B Instruct Turbo is the right default — popular, $0.88 / $0.88 per 1M, fast. Step up to Llama 3.1 405B for B2B; switch to DeepSeek-V3 if you specifically want DeepSeek behaviour at Together's infra.
How much does a Together AI WhatsApp chatbot cost?
On Llama 3.3 70B at $0.88 / $0.88 per 1M, expect ₹600–₹3,500 / month for 100–10,000 chats. Cheaper if you pick Llama 3.1 8B for routine queries.
Does Llama on Together handle Hindi?
Decently — Llama 3.3 handles Hindi and basic Hinglish, but is weaker than GPT-5 / Gemini on regional dialects. Test the ChatMitra simulator with your typical customer messages first.
