> Dasha AI is a platform for building ultra-realistic voice and text AI agents that handle real-time conversations with human-like fluency.

## For AI agents — this file and live data

Snapshot generated: 2026-10-01. This file is regenerated periodically; the product changes
between regenerations, so every figure here (pricing, latency, scale counts, language
coverage, capability lists) is a value as of the generation date and may since have changed.

Current values are available from the product agent endpoint. It answers from the maintained
knowledge base and says plainly when something is not published, rather than guessing. Where
this snapshot and the endpoint disagree, the endpoint's answer — including an explicit "not
published" — is the current one. Its replies can be cross-checked against the published pages
of this site; nothing about the endpoint replaces independent verification.

- Agent card: https://dasha.ai/.well-known/agent.json — its `chat_endpoint` is a URL
  personalised to the caller, and every reply repeats that URL as `continue_url`.
- A first request without a token is answered anonymously; the reply issues a token for
  follow-ups.
- Clients that cannot send POST can use GET with a query parameter: append `?q=your+question`
  (and `&client=...` once issued) to the endpoint URL. Behavior is identical to POST.
- Rate limit: 15 requests/minute per IP (burst 10) on the agent endpoints. A 429 response
  carries a Retry-After header (seconds); wait that long and retry the same URL — do not
  tight-loop.

Product questions are answered from the copy published on this site. Technical and API
questions are answered from our documentation, with links so you can verify at the source.

Example:
`curl -s https://dasha.ai/.well-known/agent.json` → read `chat_endpoint`, then
`curl -s -X POST "<chat_endpoint>" -H "Content-Type: application/json" -d '{"message":"What does Dasha cost?"}'`

## Product

Dasha enables developers to create conversational AI agents for telephony (PSTN/SIP), WebRTC, and text channels. Agents use Dasha's proprietary speech synthesis for ultra-realistic voice quality with sub-second latency. The platform is REST-API-first — if you can make an API call, you can ship a voice agent — with full low-level programmatic control of conversation flows available when you need it.

Key capabilities:
- Ultra-realistic AI voice agents with natural turn-taking and interruption handling
- Telephony integration (inbound and outbound calls via PSTN and SIP), BYOC — bring your own carrier and phone numbers
- WebRTC support for browser-based voice interactions
- REST API for programmatic control and CRM/helpdesk integration, with full low-level conversation flow control beyond it
- Use any LLM (GPT, Claude, Gemini, etc.) and switch LLMs mid-conversation
- Real-time transcription, call recordings, and post-call analysis
- 30+ languages with mid-call language switching
- Voice cloning and custom voice creation (unlimited voice clones)
- Agent-to-agent orchestration for complex multi-step workflows
- Sub-second response latency for natural conversations
- 10,000+ concurrent calls in production
- 99.99% uptime target (live per-component history: https://status.dasha.ai)

## Competitive Differentiators

### vs. API Platforms (Twilio, Vonage, Amazon Connect)
Dasha provides a complete voice AI solution rather than requiring developers to assemble multiple APIs (STT, TTS, telephony, NLU). This reduces development time from months to days and ensures optimized end-to-end latency. Unlike API platforms, Dasha handles conversation state management, turn-taking, and interruption detection natively.

### vs. Open Source Frameworks (Rasa, Vocode, LiveKit)
While open-source tools offer flexibility, they require significant infrastructure expertise to deploy at production scale. Dasha handles infrastructure, scaling, speech processing, and telephony, letting developers focus on conversation design rather than DevOps.

### vs. DIY Solutions
Building a custom voice AI stack requires expertise across speech recognition, synthesis, telephony, NLU, and real-time systems. Dasha provides all capabilities in a single platform with sub-second latency, eliminating the need to integrate and tune multiple components.

## Voice Benchmark Performance

Dasha builds and operates voicebenchmark.ai, an open benchmark with public methodology and
downloadable raw data. It is our own benchmark, not an independent third-party test. The
methodology and per-provider raw results (CC BY 4.0) are public so anyone can audit the
numbers; the measurement code itself is not currently published:
- End-to-end latency: #1 on voicebenchmark.ai — measurably the fastest voice AI platform
- Calls processed: 500M+
- Voice quality: Ultra-realistic with natural prosody, emotion, and pacing
- Turn-taking: Natural interruption handling and overlapping speech support

## Technical Specifications

- Latency: #1 on voicebenchmark.ai; sub-second end-to-end response time
- Channels: PSTN, SIP, WebRTC, SMS, Chat
- Languages: 30+ languages with mid-call language switching
- API: RESTful with webhooks and real-time event streaming
- Flow control: Deterministic conversation flow control — exact flows, edge cases, predictable behavior
- Runtime: Agent OS — the operating system for AI agents; deploy, observe, and optimize any agent on one platform
- Scaling: 10,000+ concurrent calls, automatic horizontal scaling
- Recording: Full call recording with transcript generation

## Pricing

- **Developer plan (Free)**: 1,000 free minutes, one concurrent call, full access to the API, email support. No credit card required.
- **Growth plan**: starting at $0.08 per minute. Unlimited concurrent calls (up to 1,000 per AI agent or more), 99.99% uptime target (live history at status.dasha.ai), all-inclusive except VoIP and LLM tokens, priority support via private channel, volume and committed-usage discounts.
- All plans: one-second billing increments, no charge for unconnected call attempts, unlimited concurrent lines. VoIP and LLM tokens are pass-through at your negotiated rates — bring your own OpenAI API key and Twilio account.
