Why flat pricing matters
No hidden extras
₹2/min is the whole price for a standard call — telephony included. Nothing added on top for the model or speech layer.
One rate, every language
The same flat ₹2/min applies across all 27 Indian languages plus English — no per-language pricing tiers to track.
Bring your own number
Already have a Plivo number? Import it and keep your existing DLT registration — we charge ₹0 for that.
Predictable billing
One line item per call. No provider invoices to reconcile, no usage-based surprises — just minutes used × ₹2.
What's inside the ₹2/min rate
We run and tune the voice pipeline so you don't have to shop and manage individual providers — it's all inside one flat rate.
Bring your own phone number

Frequently asked questions
What does ₹2/min actually include?
+
Everything for a standard voice call: the LLM, speech recognition, text-to-speech, and telephony. It's a flat, all-inclusive rate — not a base fee with provider costs added on top. Speech-to-speech (realtime voice on an external premium model like GPT-4o Realtime) is the one exception — that's a clearly-labeled add-on on top of the voice rate, since it runs on a different, more expensive model.
Can I bring my own phone number?
+
Yes — import an existing Plivo number and keep your DLT registration. ThinnestAI charges ₹0 for that; you just keep paying Plivo directly. Or buy an Indian number from us for ₹250/mo.
Do I need to bring my own LLM, STT or TTS keys?
+
No. ThinnestAI runs a curated provider stack behind the ₹2/min rate — you don't manage individual provider accounts or keys for the model or speech layer. That's what keeps pricing flat and predictable instead of a bundle of separate provider bills.
Why a flat rate instead of pass-through provider billing?
+
Predictability. One number — ₹2/min — tells you exactly what a call costs before you make it, with no separate STT, LLM or TTS line items to track or reconcile against provider invoices.
Is there a free tier?
+
Yes — every new account gets 25 free voice minutes and 200 free chat replies on Trial, no card required, using our curated free models.
