ThinnestAI vs Sarvam AI
Sarvam builds India's sovereign Indic foundation models. ThinnestAI is the voice agent platform that ships Sarvam two ways — platform-managed (zero config) and BYOK (your keys).
- Sarvam builds best-in-class Indic foundation models. ThinnestAI is a voice agent platform that ships Sarvam in two modes — platform-managed (free-tier, zero-config) and BYOK (bring your own Sarvam keys).
- Sarvam's Samvaad agent product has no published per-minute rate. ThinnestAI is a flat ₹1.5/min platform fee regardless of whether you use Sarvam platform-managed or BYOK.
- Choose Sarvam directly if sovereign India-hosted foundation models and Samvaad's managed agent are what you want. Choose ThinnestAI if you want a flow editor, phone/SIP, billing, and Sarvam inside as either a managed or BYOK option.
Pricing note
Sarvam publishes per-unit API rates for STT (around ₹30/hour), TTS (Bulbul v3 around ₹30 per 10K characters) and Sarvam LLMs (currently free-tier for most endpoints — verify on sarvam.ai). Their Samvaad conversational agent product does not have a public per-minute rate card. ThinnestAI charges a flat ₹1.5/min platform fee, and Sarvam is available two ways: (1) platform-managed — no setup, included in our free tier, or (2) BYOK — bring your own Sarvam API key and we pass usage through at Sarvam's published rates.

Frequently asked questions
Is ThinnestAI a competitor to Sarvam?
+
No. Sarvam builds Indic foundation models (LLM, TTS, STT). ThinnestAI is a voice agent platform that ships Sarvam in two modes: platform-managed (we host the integration, no API key needed, free tier) and BYOK (you bring your own Sarvam API key). The two are complementary — most ThinnestAI Hindi deployments use Sarvam under the hood.
What's the difference between Sarvam platform-managed and Sarvam BYOK on ThinnestAI?
+
Platform-managed means ThinnestAI handles the Sarvam integration for you — zero config, no API key, included in our free tier. BYOK means you bring your own Sarvam API key and we pass usage through at Sarvam's published rates. Pick platform-managed to get started fast; pick BYOK if you already have a Sarvam account with custom quotas or billing arrangements.
Can I use Sarvam Bulbul TTS and Saaras STT inside ThinnestAI?
+
Yes — both models are wired into ThinnestAI. Sarvam Bulbul v3 is one of our default TTS options for Hindi, Marathi, Tamil, Telugu and other Indic languages. Saaras is wired for STT. You can use them platform-managed or BYOK.
What's Samvaad and how is it different from ThinnestAI?
+
Samvaad is Sarvam's own managed agent product built on Sarvam's foundation models. ThinnestAI is a voice agent platform with a flow editor, phone/SIP, billing and a multi-provider provider router — and Sarvam is one of the providers inside. Samvaad's per-minute pricing is not public; ThinnestAI is flat ₹1.5/min regardless of provider choice.
Which gives better Hindi voice quality?
+
Sarvam Bulbul v3 is excellent for Hindi — and it is exactly what ThinnestAI uses when you pick Sarvam for a Hindi agent. The quality is the same whether you go direct to Sarvam or through ThinnestAI. ThinnestAI adds the flow editor, phone, compliance, and multi-provider routing around it.
Is Sarvam cheaper or more expensive than ThinnestAI?
+
Not directly comparable. Sarvam sells per-unit API rates; ThinnestAI sells a flat ₹1.5/min platform fee plus either included (platform-managed) or pass-through (BYOK) provider cost. For a typical Hindi voice workload using Sarvam platform-managed on ThinnestAI, the all-in cost is usually lower than building direct on Sarvam APIs because you skip the engineering cost of stitching STT + LLM + TTS + phone together.
