You need the calling product (numbers, campaigns, global languages), not only the model meter.
Indic-only, you want the foundation-model vendor, ₹3.50 PAYG is the budget.
Tabbly vs Sarvam AI side-by-side

What Sarvam AI actually is
Sarvam is India’s model lab turning into a voice-agent SKU. The ₹3.50 PAYG rate (models in) is the number everyone will screenshot. Tabbly’s counter is the rest of the product: numbers in 50 countries, 50+ languages beyond the Indic 11, no-code campaigns, unlimited concurrency, and a blended $0.04–$0.05 international rate when you leave India.
Where they are strong
- Owns Indic models — not a wrapper on only US speech APIs.
- Aggressive published ₹/min for the model stack.
- First-class code-mix (Hinglish and friends).
What to watch
- Telephony extra, so loaded cost depends on your carrier.
- Minute bands and monthly fees on Pro/Growth.
- Not a global DID / 50-language calling product.
Price per minute — the loaded number
Tabbly’s published card is From $0.05/min ($0.04/min on large committed volumes); India list ₹6.80/min PAYG or ₹5.10/min from 5,000 min/month. Tabbly bills to the second. Indian numbers are listed around ₹450/month on the enterprise calculator; telco on India PSTN is a small add-on (about 0.75 paisa/min). Public voice-agent rates are $0.05/min PAYG, $0.04 committed, India ₹6.80 / ₹5.10 from 5k minutes.
Sarvam AI publishes Voice Agents PAYG ₹3.50/min (models included); Pro ₹3.25 + ₹9,999/mo; Growth ₹3.15 + ₹49,999/mo; telephony and numbers extra. GST extra.. This is one of the lowest model-included INR rates published in 2026. It is not a full telco bundle — carrier is separate, like Bolna.
Finance teams should model three lines: (1) the vendor’s AI/hosting meter, (2) STT/LLM/TTS if those are BYO, (3) PSTN. A ₹3 or 6¢ headline that excludes the carrier is not cheaper than a ₹5.10 committed Tabbly minute until you add telco. Conversely, Tabbly is not automatically cheaper than VoiceCallingAI’s ₹3 pack or Sarvam’s ₹3.50 model-included PAYG on pure India traffic — those vendors can win on rupees. Tabbly’s commercial case is seconds billing, language coverage, and India + export on one invoice.
Languages
Tabbly: 50–60+ languages, including Hindi, Hinglish, Tamil, Telugu, Kannada, Marathi, Gujarati and major global languages
Sarvam AI: 11 Indian languages + English, with code-mixed speech: Hindi, Tamil, Telugu, Bengali, Marathi, Gujarati, Kannada, Malayalam, Punjabi, Odia, Assamese
For India, the test is not “do they list Hindi.” It is Hinglish code-switch, South Indian languages on the same agent, and whether English/Arabic/Spanish are available if you later call Dubai or Singapore. Sarvam AI is a 12 (11 Indic + English) language story. Tabbly is a 50+ language story with Indic as a first-class set, not an add-on.
Latency and data residency
Latency. Tabbly: India and US residency options so audio does not have to hairpin every turn through a US-only region. Tabbly does not publish a single lab millisecond figure. Sarvam AI: India-hosted models; good Indic ASR/TTS story. Confirm live with your carrier. Ignore US lab milliseconds for a Jio caller. Ask for a recorded +91 round-trip: connect-to-first-word, barge-in, and time-to-interrupt.
Residency. Tabbly: India / USA data residency (stated on tabbly.io) Sarvam AI: India research/product company; agent data on Sarvam’s Indian cloud unless contracted otherwise DPDP is a contract line, not a homepage adjective. If you are regulated, get the region and subprocessors in writing.
Builder, telephony, concurrency
Tabbly ships No-code agent builder plus APIs; campaigns, recordings, analytics, 50+ countries, local numbers including +91, unlimited concurrency on published plans, concurrency unlimited on published product pages.
Sarvam AI ships Managed Voice Agents platform (testing, analytics) plus speech APIs (STT ~₹30/hour, TTS ~₹3 / 1k chars on older API cards). Telephony: Listed separately from the ₹3.50 agent rate. Concurrency: Plan bands by monthly minutes (PAYG <3k, Pro to 16k, Growth to 65k, Business/Enterprise above).
Ops teams that need 50-country DIDs and a CRM-style campaign product out of the box
The honest split
For an Indic-only, India-hosted, model-included minute, Sarvam is priced to win. For a company that also calls the US and UAE, or needs a campaign console and second billing, Tabbly is the broader product. Many stacks will use Sarvam speech inside Tabbly-like products over time — they are not always mutually exclusive.
Buying checklist
- Get a loaded-minute quote (models + India PSTN + number rental), not a hosting-only headline.
- Run 20 Hindi and 20 English live calls on +91. Score completions, not demo polish.
- Confirm language list against your actual states — Tamil and Telugu drop off many “Hindi + English” tools.
- Write down data region, retention, and whether recordings leave India.
- If you might call the US, UK, SG or AE later, do not lock into an India-only vendor without an exit.
