AssemblyAI
Universal-2 speech-to-text with speaker diarisation and audio intelligence
AssemblyAI provides a speech-to-text and audio intelligence API. Its Universal-2 model offers high-accuracy transcription with built-in speaker diarisation, sentiment analysis, topic detection, and PII redaction. The Nano model targets cost-sensitive batch workloads. Pricing is per audio hour.
Nebius AI
HGX B300, B200, H200, H100 — European AI cloud with GDPR-native data sovereignty
Nebius AI is a European cloud provider offering GPU compute and LLM inference with GDPR-native data sovereignty. GPU catalog includes HGX B300, B200, H200, H100, RTX PRO 6000, and L40S — with preemptible rates significantly lower than on-demand. The Token Factory product enables high-throughput batch inference. Nebius also offers managed Kubernetes, PostgreSQL, MLflow, and object storage. Check nebius.com for current rates.

Frequently asked questions
AssemblyAI FAQs
How is AssemblyAI priced?
AssemblyAI charges per audio hour. Universal-2 is $0.37/hour and Nano is $0.10/hour. Additional audio intelligence features (diarisation, sentiment, PII redaction) are priced separately. See assemblyai.com/pricing for current rates.
What is Universal-2?
Universal-2 is AssemblyAI's flagship transcription model with built-in speaker diarisation, sentiment analysis, topic detection, and PII redaction. It is designed for meeting intelligence and call analytics use cases.
What is LeMUR?
LeMUR (Leveraging Large Language Models to Understand Recorded Audio) is an AssemblyAI feature that lets you run LLM-powered Q&A, summarisation, and action-item extraction directly over transcribed audio without building a separate pipeline.
Nebius AI FAQs
What GPU hardware does Nebius AI offer?
Nebius AI offers HGX B300, B200, H200, H100, RTX PRO 6000, and L40S — with preemptible rates significantly lower than on-demand. Check nebius.com for current rates.
What is Nebius Token Factory?
Token Factory is Nebius AI's high-throughput batch inference product. It processes large volumes of inference requests at reduced per-token cost compared to real-time inference, making it ideal for batch processing workloads.
Is Nebius AI GDPR-compliant?
Yes. Nebius AI operates data centres in Europe (Amsterdam and other EU locations), making it a strong choice for European businesses with GDPR data residency requirements.
