Vapi is a developer platform. You choose the transcriber, the language model, the voice and the telephony, and you pay each provider's cost plus Vapi's hosting fee. That gives an engineering team a lot of control, and it also means someone on that team has to assemble, tune and monitor the stack.

Teams that look at alternatives usually want a single predictable rate, an agent that business users can set up without engineers, or calls that land in a CRM with the follow-up already scheduled. Teams that call Indian customers also check Hindi and regional language quality, Hinglish handling and TRAI compliance. Our Vapi pricing guide works through the per-minute cost in detail.

GRX10 Voice AI is a ready AI voice agent for inbound and outbound calls. It runs on a single audio-to-audio model with a patent-pending architecture, so speech does not pass through a stitched speech-to-text, LLM and text-to-speech chain.

• ▸Response time. First-word response under 700 ms on real phone calls.
• ▸Languages. All languages*, including Indian languages with Hinglish code-switching, plus Arabic and Spanish, at one rate.
• ▸Setup. You describe the agent's job in one sentence, and GRX10 generates the prompt, greeting, guardrails and voice in the agent studio.
• ▸After the call. Every call is recorded, transcribed, summarised and written to the CRM with a disposition, and a warm handoff passes the caller to a person with full context.
• ▸Pricing. $0.119 per minute for the platform plus telephony at carrier cost. A typical 2-minute call is about $0.24 on the platform line.
• ▸Compliance. DPDP Act 2023 ready in India, with outbound calls inside TRAI's 9 am to 9 pm hours. In the US, GRX10 supports TCPA-compliant workflows and reviews requirements per use case before go-live.

• ▸Retell AI. Retell lists $0.07 to $0.31 per minute, built from its $0.055 voice infrastructure fee plus the LLM, voice and telephony you choose. Our Retell AI pricing guide and GRX10 vs Retell page cover it in detail.
• ▸Bland AI. Bland states that the LLM, transcription and voices are included in its per-minute rate, with no token charges. Its Start plan is $0.14 per minute with 10 concurrent calls, and its Build plan is $0.12 per minute with a $299 monthly platform fee and 50 concurrent calls.
• ▸Synthflow. Synthflow's pricing page lists enterprise contracts starting at $30,000 a year, scoped on call volume, concurrency, telephony, integrations and launch support. See our Synthflow alternatives page.
• ▸Bolna. Bolna is a developer platform focused on Indian languages, starting at 6¢ (₹5.52) per minute on pay-as-you-go. See our Bolna pricing guide and Bolna alternatives.

Start with the full cost of a typical call, including telephony, any package or platform fee, and add-ons such as HIPAA. Then estimate how much engineering time each option needs before the first live call and every month after it. A low per-minute rate on a developer platform can cost more overall if your team spends weeks building the agent and the CRM integration.

If you call customers in India, test each agent on real Hindi and Hinglish calls on Indian phone lines, and confirm that outbound campaigns respect TRAI calling hours and DND. If you sell in the US, confirm how each vendor handles call-recording consent and TCPA rules for your use case.
