## Inworld AI

Inworld AI has evolved from its origins as a character engine for games into a realtime voice and inference platform aimed at consumer applications. The core pitch is latency: the company advertises time-to-first-audio in the tens of milliseconds for its Flash voice model and sub-second time-to-first-token for hosted LLMs, which matters for companions, tutors, coaches and any product where a pause breaks the illusion of conversation.

On the voice side, Inworld ships Realtime TTS-2 for expressive, steerable speech across a very large number of languages and dialects, Realtime STT-1 for streaming transcription that also returns traits such as emotion, style, age and accent, and a speech-to-speech endpoint that handles listening, reasoning and speaking over a single WebSocket or WebRTC connection. Expressive controls let developers direct delivery rather than only choosing a preset voice.

On the model side, Inworld Inference hosts a catalogue of open text, image, video and decision models that the company tunes from weights down to kernels, competing on price, throughput and reliability. Developers typically mix one hosted LLM with a voice model, paying per million characters for speech and per million tokens for inference, with volume and enterprise tiers available.

**Pricing & Plans:** Usage-based. Speech is billed per million characters (published enterprise rates sit far below legacy voice vendors) and STT per hour of audio; hosted LLMs are billed per million input, output and cached tokens. Enterprise and volume commitments are quoted on request, and a free playground plus trial credits let you test models before buying.

- **Realtime text to speech:** Streaming TTS with latency as low as tens of milliseconds to first audio, expressive style control and support for several hundred languages and dialects.
- **Streaming speech to text:** Realtime transcription that returns voice traits such as emotion, style, age and accent alongside the transcript.
- **Speech to speech endpoint:** One WebSocket or WebRTC connection that listens, reasons with any LLM and talks back, for natural turn-taking agents.
- **Inworld Inference:** Managed hosting for open text, image, video and decision models, optimised for time to first token, cost per request and reliability.
- **Developer tooling:** Documentation, API reference, model playground, community support and a copyable 'skill' that plugs the platform into coding assistants.

**Strengths:** Strong latency numbers for both voice and LLM serving, which is the hard part of conversational products; Voice and inference available from a single vendor, reducing integration work; Very broad language coverage and multiple hosting regions; Publicly documented per-unit pricing and a playground for evaluating models

**Limitations:** Pricing is consumption based, so costs scale with engagement and need monitoring; You bring your own orchestration, guardrails and application logic; Enterprise discounts and some features require a sales conversation

## SpatialReal

SpatialReal tackles the two things that usually make digital humans impractical in production: latency and cost. Instead of streaming rendered video from the cloud, it renders the avatar on the user's device, which brings response time below 300 milliseconds, drops bandwidth to 10–15 KB/s and cuts compute cost to roughly a hundredth of a typical cloud video avatar. The result is a photorealistic character that reacts, listens and breathes in real time rather than playing back stiff animation.

The platform is aimed squarely at developers. Web, iOS and Android SDKs are available on every tier including the free trial, alongside simple APIs for integrating into existing voice agents and conversational stacks. Because it is designed for interruption and adaptive dialogue, avatars work in live settings — customer support, sales onboarding, recruiting interviews, tutoring and interactive characters — not just pre-scripted demos. SpatialReal reports over 10 million interactions processed on the platform.

Pricing runs on credits. The free trial gives 500 credits a month — about 50 avatar minutes or 4 agent minutes — with 2 concurrent sessions and a watermark. Paid tiers step up from Starter ($19/mo, 22,000 credits) through Build ($99/mo) and Scale ($299/mo) to Accelerate ($999/mo), with per-minute rates falling as volume rises. Enterprise offers custom volume and concurrency with a dedicated contact.

**Pricing & Plans:** Freemium with credit-based plans. Trial: free, 500 credits/month (~50 avatar min or ~4 agent min), 2 concurrent sessions, 10-minute cap, watermarked. Starter $19/mo (22,000 credits), Build $99/mo (120,000), Scale $299/mo (400,000), Accelerate $999/mo (1,400,000); annual billing saves 20%. Avatar minutes from ~$0.0086 to $0.0071/min and agent minutes from ~$0.1036 to $0.0856/min depending on tier. Enterprise pricing is custom on request.

- **Sub-300ms real-time interaction:** Avatars respond in under 300 milliseconds, so conversations feel immediate rather than delayed, and they keep listening, reacting and breathing while waiting for the user.
- **On-device rendering, low bandwidth:** Rendering happens on-device instead of streaming video from the cloud, which cuts bandwidth to 10–15 KB/s and compute cost to roughly one hundredth of typical cloud video avatars.
- **Cross-platform SDKs and API:** Web, iOS and Android SDKs plus simple APIs let developers integrate digital humans into existing apps and agent stacks without a heavy backend.
- **Customisable AI presence:** Appearance, behaviour and voice can be tailored to your brand or AI experience, with natural, controllable motion rather than stiff scripted animation.
- **Built for live, interruptible dialogue:** The platform is built for interruption, reaction and adaptive dialogue, so users can talk over, pause and redirect the avatar naturally.

**Strengths:** Sub-300ms latency makes real-time conversation feel natural rather than laggy; On-device rendering slashes bandwidth to 10–15 KB/s, so avatars work on ordinary connections and devices; Around 1/100 compute cost versus cloud video avatars reduces scaling expenses significantly; Identical SDK coverage (Web, iOS, Android) on the free trial and all paid plans

**Limitations:** Credit-based pricing with separate avatar and agent minute rates takes some arithmetic to forecast real monthly cost; The free trial caps you at 500 credits, 2 concurrent sessions and 10-minute sessions with a watermark; Agent-mode minutes are roughly twelve times the cost of avatar-only minutes, which matters for long-running voice assistants; Session duration limits and concurrency rise only at the higher paid tiers
