Freemium

Communication API that gives an AI agent a real phone number with voice, SMS and native iMessage on one line, provisioned in seconds.

Key features

  • Agent Phone Numbers on Demand: Real US, Canadian and international numbers are provisioned through a single API call, giving an agent its own phone identity in seconds.
  • Native iMessage with Fallback: Agents send blue-bubble iMessage from their own number, including inbound and cold outbound, with automatic RCS and SMS fallback.
  • Autonomous Outbound Calls: A call is placed with a plain-language instruction and constraints - what to ask, what to book, what price ceiling to hold - and runs on its own with real-time transcription and TTS replies.
  • Unified Multi-Channel Webhook: One webhook receives voice, SMS and iMessage events in the same format, so there is no per-channel plumbing to maintain.
  • MCP Server and Prompt Setup: Dial works out of the box as an MCP server with Claude Code, Cursor, Windsurf and Grok, and a single pasted prompt lets an agent complete the whole setup itself.
  • Self-Hosted or Managed Voice: Voice can run against your own LLM over WebSocket at a lower per-minute rate, or end to end on Dial's hosted model.
  • SDKs and REST API: Node.js and Python SDKs plus a LangChain integration and a direct REST API cover code-first integration paths.
  • Compliance Certifications: GDPR, CCPA, SOC 2 and HIPAA credentials are in place for security reviews.

Best for

  • Agent Errand Calls: Sending an agent to call a vendor, get a quote and book the earliest slot only if it stays under a stated budget, then reading the transcript afterward.
  • Customer Support Lines: Giving an AI support agent an inbound number that handles voice and text on the same line with transcripts routed to your systems.
  • Existing Chat Agents: Adding a real phone number to agents already running in WhatsApp, Telegram or a setup wizard, so SMS and voice work without building a telecom layer.
  • Autonomous Company Operations: Giving agent-run businesses a real phone identity so they can be reached and can transact by phone.
  • Verification and Notifications: Two-way SMS through the same number for confirmations, reminders and inbound replies routed to a webhook.
  • Prototyping by Prompt: Having a coding agent stand up a working phone number and place a test call within a minute, before writing any integration code.

Paid

Post-training platform driven by AI coding agents like Claude Code and Cursor — returns deployable specialized models.

Key features

  • Agent-Driven Workflow: Claude Code, Cursor, or Codex describe the run in natural language and launch training
  • Fixed-Price Quotes: Flash returns one quote and ETA up front — no per-token metering or GPU-hour surprises
  • SFT + GRPO Pipeline: Supervised fine-tuning followed by reinforcement learning past the frontier baseline
  • Custom Kernels: FlashAttention, fused SwiGLU, RMSNorm, RoPE and QK-norm optimized per model architecture
  • Exportable Weights: Every run returns downloadable weights in standard formats to serve on your own infrastructure
  • Data Isolation: Encrypted in transit and at rest, never used to train anything but your model
  • Reproducible Runs: Pinned configs, seeds, and checkpoints so every run always finishes

Best for

  • Turn generic LLM capability into a specialized production feature for your product
  • Have an AI coding agent orchestrate the entire fine-tuning loop without leaving your IDE
  • Retrain small specialized models on the fly as your task data evolves
  • Route the 90% routine tail of LLM calls (classify, extract, rerank, moderate) to a cheap specialized model
  • Beat a frontier model's zero-shot accuracy on a domain task with a sub-10B tuned model
  • Keep model weights in-house instead of relying on hosted API-only fine-tuning
