AI Transcription 85% Cheaper Than OpenAI: Multimodal Pricing for Bot Developers

Hanzo Bot delivers speech-to-text at $0.0009/minute — 85% cheaper than OpenAI Whisper — plus image generation at the industry's lowest price of $0.00013/step.

Audio-enabled bots have always been expensive to run. Voice assistants, transcription services, podcast summarizers, meeting note-takers — every minute of audio costs money. At OpenAI's Whisper pricing, a lot of money.

Today we're announcing multimodal pricing on Hanzo Bot that changes the economics of building bots that can hear, see, and create.

These prices apply to Hanzo's proprietary Zen3 model family, accessible through the same API that serves 100+ models from every major provider.

What 85% Cheaper Means in Practice

At OpenAI's Whisper pricing of $0.006 per minute:

  • 1,000 hours/month = $360/month
  • 10,000 hours/month = $3,600/month
  • 100,000 hours/month = $36,000/month

At Hanzo's Zen3 Audio Fast pricing of $0.0009 per minute:

  • 1,000 hours/month = $54/month
  • 10,000 hours/month = $540/month
  • 100,000 hours/month = $5,400/month

For a startup processing 10,000 hours of audio monthly, that's $3,060 saved every month — $36,720 per year.

Four Audio Models

Zen3 Audio ($0.0015/min) — Best quality. Multi-language support, highest accuracy. Use when accuracy matters more than cost.

Zen3 Audio Fast ($0.0009/min) — Best value. Multi-language support, fast inference. The default choice for most workloads.

Zen3 ASR ($0.0035/min) — Real-time streaming. Sub-second latency for live transcription, voice assistants, and real-time captioning.

Zen3 ASR v1 ($0.0032/min) — Legacy streaming. For existing integrations.

Image Generation: From $0.04 to $0.00013

The Zen3 Image family covers every use case:

ModelPricingBest For
Zen3 Image$0.04/imageGeneral-purpose generation
Zen3 Image Max$0.08/imageProfessional creative work
Zen3 Image Dev$0.0005/stepExperimentation and iteration
Zen3 Image Fast$0.00035/stepReal-time generation
Zen3 Image SDXL$0.00013/stepHigh-resolution, high-throughput
Zen3 Image SSD$0.00013/stepFastest, cheapest
Zen3 Image Playground$0.00013/stepAesthetic/artistic styles

At $0.00013 per step, you can generate thousands of images per dollar. For bots that create social media content, product mockups, or design variations — this changes the unit economics entirely.

Content Safety Included

Every Hanzo Bot deployment includes access to Zen3 Guard — a 4B-parameter content safety classifier covering 9 safety categories across 119 languages. No separate moderation API needed.

All Through One API Key

Every model above — audio, image, text, safety — is accessible through the same Hanzo API key that also serves GPT-5, Claude, Gemini, and 100+ other models. One integration. One bill.
