Products, side by side
Algorithmic pairing — assembled from recorded fields, not hand-checked
Cerence
Platform
Hybrid generative-AI platform for the car cabin built on Cerence's own CaLLM model family, splitting work between the vehicle's embedded hardware and the cloud so the assistant still answers with no connection.
Inworld AI
Platform
OpenAI-compatible LLM gateway that sends each request to one of 100+ models from OpenAI, Anthropic, Google and others by rules on user attributes, context, A/B splits or cost, with failover and provider rates passed through at zero markup.
No counterpart
Cerence sells these in a stack layer with no product recorded for Inworld AI yet — nothing on the other side to compare them against.
Application
Delivers vehicle-specific insights through AI-refined search, answering questions about the vehicle.
Turnkey in-car voice assistant that carmakers deploy as-is, running core functions onboard the vehicle while reaching the cloud for live information such as news, weather and flight updates.
Brings friendly, free-flowing small talk to the car -- contextual in-car conversation distinct from vehicle-specific Q&A.
Acoustically detects a wide range of global sirens to alert the driver.
Turns drive time into productive time: a voice-based work assistant for drivers.
Always-available personal OEM representative that helps drivers understand and maintain their vehicle.
Removes noise, unwanted sounds and speech interference from in-vehicle audio.
AI agent
Handles dealership customer inquiries as part of Cerence's automotive AI agents portfolio.
Developer tool
Self-service cloud portal where developers upload their own audio to benchmark Cerence's speech recognition engines on word error rate, latency and confidence, and audition and tune the text-to-speech voice library in the browser.
Inworld AI sells these in a stack layer with no product recorded for Cerence yet — nothing on the other side to compare them against.
API service
Speech-to-speech voice-agent API in which one WebSocket session runs Inworld speech recognition with voice profiling, a chosen LLM from 100+ with tool calling and turn detection, and Realtime TTS-2 voice output.
Speech-to-text API (Inworld STT-1) that transcribes streaming or complete audio in 30+ languages with turn detection, returning voice-profile signals for emotion, vocal style, accent, age and pitch alongside the transcript.
Text-to-speech API (Realtime TTS-2 and TTS-2 Flash) with voice cloning and voice design, billed per million characters.
Infrastructure service
Dedicated NVIDIA B200 GPUs for high-volume realtime workloads such as LLM inference, dedicated TTS serving and custom model hosting, with Kubernetes access or Inworld-managed deployment, and deployed models routable through Inworld Router.
Model API
Inworld Inference provides API access to text, image, video and decision models.
