## AssemblyAI

AssemblyAI builds speech AI models and the infrastructure to run them, aimed at developers and product teams adding voice to an application. Its core offering is speech-to-text: an asynchronous API for pre-recorded audio, a realtime API for streaming and voice agents, and a synchronous API for short clips and dictation. The company's flagship accuracy model is marketed as top of independent benchmarks, with strong speaker diarization and native code-switching across dozens of languages.

On top of transcription, AssemblyAI offers a Speech Understanding API that layers tasks such as summarization, sentiment, topic detection, PII redaction, content moderation and guardrails onto transcripts. It has also released its first text-to-speech model, AssemblyAI-TTS-1, built for voice agents on live calls, plus an LLM Gateway for routing model calls and a Dictation API. Models can run on AssemblyAI's managed inference cloud, or self-hosted in a customer's own VPC or on-premises environment.

Pricing is pay-as-you-go after a free trial: for example, pre-recorded transcription is billed per audio hour, with optional add-ons such as speaker diarization, keyterms prompting and medical or veterinary modes priced separately. Enterprise plans offer custom rate limits, higher concurrency and compliance features including SOC 2 Type 2, HIPAA and GDPR.

**Pricing & Plans:** Free trial to start, then pay-as-you-go per audio hour and per add-on feature — for example around $0.15/hr for the Universal-2 model and around $0.21/hr for the more accurate Universal-3.5 Pro model, with extras like diarization billed individually. Enterprise and custom-rate-limit plans are available via sales.

- **Async, realtime and sync speech-to-text:** Choose pre-recorded transcription for files, a realtime API for live streams and voice agents, or a synchronous endpoint for short clips and dictation.
- **Audio intelligence and Speech Understanding:** Layer summarization, sentiment, topic detection, PII redaction, content moderation and guardrails onto transcripts without building your own models.
- **Text-to-speech for voice agents:** AssemblyAI-TTS-1 is trained on real phone calls for natural, low-latency speech, targeted at IVR and voice-agent use cases.
- **High accuracy with diarization:** Flagship models emphasise exact transcription, speaker labels and native code-switching across many languages, supported by published benchmarks.
- **Flexible deployment:** Run models on AssemblyAI's managed cloud with unlimited concurrency, or self-host in your own VPC or on-prem for full data control.

**Strengths:** One API family covering transcription, understanding and text-to-speech; Transparent per-hour pay-as-you-go pricing with a free trial; Self-hosting option for teams with strict data-residency requirements; Strong accuracy and diarization performance backed by published benchmarks

**Limitations:** Costs scale with volume and add-ons can raise the effective per-hour rate; Some advanced features are model-specific and not available on every model; Heavier product surface than a simple transcription API may be overkill for basic needs

## Gabber

Gabber provides the plumbing for realtime, multimodal AI applications. Instead of stitching together separate speech recognition, speech synthesis, and vision services, teams use Gabber's orchestration engine to wire them into a single low-latency pipeline. The platform's App Flow Builder is a visual canvas where developers drag composable nodes for inference, logic, and state, then connect them into an application that can see, hear, and respond in under a second.

The system is built around streaming and multi-participant scenarios. Apps can mix video, screen, audio, and text inputs from multiple streams and users at once, making it suited to live coaching, interactive avatars, gaming companions, and assistive tools. Developers bring their own models or use Gabber-hosted options, and custom building blocks let apps call external APIs and SDKs so the AI can take real actions.

Deployment is flexible: teams can run on Gabber's managed cloud or host the stack locally. Pricing is pay-as-you-go per session hour, and concurrent sessions are unlimited, which keeps the cost model predictable for prototypes and production apps alike.

**Pricing & Plans:** Pay-as-you-go per session hour (around $0.50/hour base session plus STT at roughly $0.15/hour; TTS and LLMs priced at cost or by provider). Enterprise plans offer custom integrations, dedicated infrastructure, volume discounts, and priority support. A free tier/get-started path is also offered.

- **Graph-based orchestration:** A drag-and-drop App Flow Builder connects inference, logic, and state nodes so you can design complex realtime flows without custom glue code.
- **Multimodal realtime inference:** Built-in low-latency orchestration for vision-language models, speech-to-text, and text-to-speech in a single pipeline.
- **Multi-stream, multi-participant:** Combine video, screen, audio, and text from several streams and participants simultaneously for rich interactive apps.
- **Composable, extensible nodes:** Mix and match building blocks, or write custom nodes to interface with your own API or SDK so the AI can act on external systems.
- **Flexible deployment:** Run in Gabber's managed cloud or host the stack locally, with unlimited concurrent sessions and per-hour billing.

**Strengths:** Low-latency orchestration engineered specifically for realtime multimodal apps; Visual builder lowers the barrier to wiring STT, TTS, VLMs, and LLMs together; Unlimited concurrent sessions with transparent per-hour pricing; Custom nodes and integrations let the AI take real actions

**Limitations:** Pay-as-you-go hours can add up for always-on production workloads; Realtime multimodal work still requires developer skill and testing; Some advanced app templates and features are gated behind higher tiers
