"Sarvam AI vs ChatGPT" is really two comparisons. For someone chatting on a phone, it's Sarvam's Indus app against the ChatGPT app. For a business, it's Sarvam's rupee-billed APIs for speech, translation and text against OpenAI's global models. The answer is different in each case, and in both it depends heavily on whether your work is in English or in an Indian language.
This post compares them on the things that decide the choice in India: language and voice quality, price, invoicing, where your data is stored, and how mature each product is. Facts are from the companies' own announcements and dated reporting, checked on 29 September 2026.
The short answer
Pick ChatGPT for English-first work that needs strong reasoning, coding help, long documents, custom GPTs and a large ecosystem of integrations. Pick Sarvam when the job is in Indian languages — especially voice: transcription, voice bots, call-centre automation, dubbing — or when you need an Indian vendor with rupee billing and India-hosted infrastructure. Plenty of teams will reasonably use both: ChatGPT for general reasoning, Sarvam for the Indian-language layer.
The consumer apps: Indus vs ChatGPT
Sarvam launched Indus, its chat app, on 20 February 2026 at the India AI Impact Summit, for web, Android and iOS. TechCrunch reported at launch that it runs on Sarvam's 105-billion-parameter model, takes text or voice input, and was in beta with access limited to India; co-founder Pratyush Kumar said it was rolling out on limited compute, so new users might hit a waitlist. Early users also noted rough edges: you couldn't delete individual chats without deleting your account, and the reasoning mode couldn't be switched off. Indus hadn't announced paid consumer plans when it launched; check the app for its current terms.
ChatGPT is a far more mature product. It has more than 100 million weekly users in India, according to figures cited by TechCrunch in February 2026, and offers file analysis, image generation, voice mode, memory, custom GPTs and apps on every major platform. In India there's a free tier, ChatGPT Go at ₹399 a month (launched August 2025, and given free for a year to users in India who signed up from 4 November 2025), and ChatGPT Plus at ₹1,999 a month. Our post on free AI subscriptions in India covers the Go renewals that start in November 2026.
For a casual user who mostly types in English, ChatGPT is the more capable app today. For someone who wants to speak to an assistant in Tamil, Marathi or code-mixed Hinglish and get a natural answer back, Indus is worth trying alongside it: that's the use case it was built for.
Indian languages and voice
This is Sarvam's home ground. Its speech-recognition model, Saaras V4, launched in September 2026, covers 22 Indian languages plus English, detects the language automatically, handles code-mixed speech, and can output verbatim, normalised, code-mixed, transliterated or translated text. Sarvam says streaming latency is under 150 milliseconds. Its Bulbul text-to-speech voices and Samvaad voice-agent platform, which it says has handled 325 million minutes of calls, are built around Indian accents and phone-quality audio.
ChatGPT understands and writes the major Indian languages, and its voice mode works in Hindi and others, but quality is uneven across languages and it isn't tuned for Indian telephony or code-mixed speech the way Sarvam's models are. One caveat applies to both: Sarvam's accuracy numbers are its own, and we haven't seen an independent benchmark comparing the two on Indian-language audio. If voice quality is the deciding factor, test both on a few minutes of your own real recordings before committing.
Price, rupee billing and GST
Sarvam's APIs are pay-as-you-go and priced in rupees. As of 28 September 2026 its pricing page listed speech-to-text at ₹30 per hour of audio (₹45 with speaker diarisation), text-to-speech at ₹30 per 10,000 characters, translation at ₹20 per 10,000 characters, and its Sarvam 105B model at ₹29.28 per million input tokens and ₹73.20 per million output tokens. New accounts get ₹100 of free credit. As an Indian company, Sarvam can issue an Indian GST invoice, which matters if you want to claim input tax credit.
ChatGPT's consumer plans are shown in rupees, but OpenAI doesn't issue an Indian GST invoice for them. A GST-registered business buying a foreign AI subscription generally has to account for GST itself under reverse charge; our post on GST on foreign AI subscriptions explains how that works. OpenAI's API is billed in US dollars per token, so your rupee cost also moves with the exchange rate.
Where your data is stored
Sarvam markets its platform as built and hosted in India, and Indus as running on India-hosted infrastructure. Sarvam's API catalogue now also includes third-party models such as Gemma 4 31B, GLM-5.3 and DeepSeek V4 Flash, so if data location matters, confirm the hosting region for the specific model you use in your contract rather than assuming it applies to everything.
OpenAI announced data residency in India on 7 May 2025, alongside Japan, Singapore and South Korea. It covers ChatGPT Enterprise, ChatGPT Edu and the API platform: eligible new Enterprise and Edu customers can have conversations, uploaded files and other customer content stored at rest in India, and API customers can create a project with India selected as the region. It doesn't cover the Free, Go or Plus consumer plans. So for a large organisation with residency requirements, both are now options. For an individual or small team on a consumer plan, only Sarvam keeps data in India. In February 2026 OpenAI also announced a partnership with Tata Group for 100 MW of data-centre capacity in India, with plans to scale towards 1 GW.
Which one to choose
Choose ChatGPT if your team works mostly in English and needs the strongest general assistant: writing, analysis, coding, research, and integrations with the rest of your software. Go at ₹399 a month is enough for most individuals, and Plus for heavier use.
Choose Sarvam if you're building anything voice-led or Indian-language-first — a support line in regional languages, transcription of Hindi and Tamil calls, a multilingual WhatsApp or IVR bot — or if procurement needs an Indian vendor, rupee billing, a GST invoice and India-hosted data at a small-business scale.
Use both if you need top-tier reasoning and good Indian-language voice. That's a common pattern: a global model does the thinking, and Sarvam handles speech in and speech out. Our tool pages for Sarvam AI and ChatGPT list each one's India-readiness details in full.
