Bolna AI Pricing vs Bolti: Which Voice Agent Costs Less?

Evaluating Bolna pricing for your voice AI agents requires looking beyond the base platform fee to understand the total cost of ownership. Bolti, a voice AI platform for building production-ready conversational phone agents, offers a transparent ₹7/min pay-as-you-go rate with a 50-minute free trial, making it easy to compare costs against legacy platforms.

What Is Bolna AI Pricing?

Bolna AI pricing is structured around monthly subscription tiers with usage limits, rather than a pure pay-as-you-go model. Because their exact per-minute rates, overage charges, and feature gating are not publicly transparent, most teams must book a sales call to get a binding quote for production volumes.

This lack of upfront transparency makes budgeting difficult for growing teams. If your team runs 1,000 outbound calls a day in cities like Mumbai or Bangalore, a difference of just ₹1.50 per minute between platforms translates to an extra ₹45,000 every month. Comparing this to alternative platforms like Ringg AI or Bolti helps clarify where you are overpaying for bundled features you might not even use.

How Does Bolti Pricing Compare to Bolna?

Bolti charges a flat platform fee of ₹7/min with no monthly minimums, setup fees, or feature gating. You pay only for the exact minutes you use, with full access to all developer tools, APIs, and multi-language features from day one.

Here is what is included at ₹7/min on Bolti:

• Complete Provider Freedom: Choose your own STT, LLM, and TTS providers per agent via the Speech and LLM tabs in the dashboard.
• Telephony Flexibility: Bring your own carrier (BYOC) via Twilio, Plivo, or Exotel SIP trunks, or use Bolti-managed numbers.
• Full API Access: Every dashboard action is available as a REST API call, allowing deep CRM and helpdesk integrations.
• No Tiered Gating: Features like PII redaction, sub-accounts, and custom LLM endpoints are not locked behind expensive enterprise tiers.

Your total cost per minute is the Bolti platform fee (₹7/min) plus the direct cost of your selected STT, LLM, and TTS providers. This transparent pass-through model is often far cheaper than bundled pricing models that markup provider costs. Check the details on the Bolti pricing page.

How Does Provider Choice Impact Your Voice Agent Cost?

Your choice of Speech-to-Text (STT), Large Language Model (LLM), and Text-to-Speech (TTS) providers directly dictates your per-minute costs and latency. Bolti lets you mix and match these providers per agent to balance quality, speed, and budget.

• STT (Speech-to-Text): For Indian-language calls (Hindi, Tamil, Telugu, Marathi, Gujarati, Bengali), using Fennec or SarvamAI STT in the Speech tab provides native accent optimization. For English, Deepgram or Cartesia offer ultra-low latency.
• LLM (Large Language Model): For scripted, high-volume agents, Groq Llama models are extremely fast and cost-efficient. For complex, branching customer support conversations, use OpenAI GPT-4o or Gemini 2 Pro.
• TTS (Text-to-Speech): For premium English brand voices, ElevenLabs is the standard. For cost-sensitive, high-volume Indian campaigns, SmallestAI or SarvamAI keep costs low while maintaining native prosody.

Can You Use Custom or Open-Source LLMs to Lower Costs?

Yes, Bolti allows you to connect custom and open-source LLMs to bypass expensive proprietary model fees. By integrating Baseten directly into the LLM tab, you can run optimized open-source models on dedicated GPU infrastructure at a fraction of the cost of GPT-4o.

Using open-source models on Baseten helps you scale to zero so you only pay for active GPU time during business hours. Bolti supports several production-ready open models:

• DeepSeek-V3.1: The best overall balance of reasoning quality, tool-calling capability, and low cost.
• Llama-4-Maverick-17B: Optimized for the fastest time-to-first-token (TTFT) and extremely long context windows (up to 1M tokens).
• Qwen3-235B-A22B: A massive open model for complex reasoning tasks where quality is prioritized over latency.

This flexibility is highly valuable for Indian SMBs running large-scale outbound operations where proprietary API costs would otherwise be prohibitive.

What Does a Typical Deployment Actually Cost?

A typical outbound campaign running 500 minutes of calls per day on Bolti costs approximately ₹3,500 in platform fees daily, plus minor provider pass-through costs. This pay-as-you-go model prevents you from paying for idle capacity or unused subscription tiers.

Let's look at a concrete example of an outbound payment-reminder campaign in India:

• Daily Volume: 200 calls at an average of 2.5 minutes each = 500 minutes.
• Bolti Platform Fee: 500 minutes × ₹7/min = ₹3,500 per day.
• Monthly Platform Cost (25 working days): ₹87,500.
• Provider Costs (STT + LLM + TTS): Typically ranges from ₹0.15 to ₹0.80 per minute depending on your stack. Using a low-cost stack like Groq Llama + SmallestAI keeps this near the bottom of the range, while ElevenLabs + GPT-4o sits at the top.
