GDPR-Compliant Gemini Live Alternative

The European Alternative to Gemini Live.

Deepslate Opal engineered for European enterprise production. 100% GDPR compliant, zero data retention, self-hosted voice AI available.

Enterprise Security

Your Legal Team's Favorite Foundation Model.

For regulated industries, data sovereignty is not a feature request. It's a baseline requirement. Here's where Gemini Live falls short, and how Deepslate fills the gap.

Gemini Live

Legal Friction for EU Enterprises

Google Cloud APIs carry complex enterprise opt-out requirements and broad data access policies. For European banks, insurance companies, and government agencies: sending sensitive audio streams to US-centric infrastructure is a dealbreaker for most compliance teams.

Deepslate Opal

Deepslate: GDPR Voice AI by Design

Deepslate Opal is different by design. No training on your audio streams. No storage. Absolute data sovereignty. Host in our strictly EU-regional cloud or run Deepslate as a self-hosted voice AI entirely in your own VPC, air-gapped if needed.

Performance

EU-hosted. 47% faster. No transatlantic routing.

Gemini Live routes EU audio to US servers. That adds up fast. Deepslate's Frankfurt infrastructure eliminates the transatlantic hop entirely. No Schrems II exposure. No added latency.

The result: 47% faster Time-to-First-Audio-Byte and barge-in that feels genuinely human.

Deepslate leads with 71% accuracy vs. 55% for Gemini 2.5 FlashTau Labs, March 2025

Intelligence

Built for complex CX scenarios.

The Tau2-Telecom Benchmark evaluates voice AI models on tool calling, intent resolution, and end-to-end workflow completion in enterprise telecom contexts.

Opal outperforms Gemini 2.5 Flash by 16 percentage points. Pure parameter count doesn't translate to enterprise-grade reasoning.

Speech Reasoning

Direct audio understanding.

Opal doesn't transcribe audio to text and then reason. The Speech-to-Speech API processes speech natively, extracting nuance, tone, sarcasm, and context directly from the raw audio stream.

Big Bench Audio v2.1: Opal scores 90 out of 100, outperforming Gemini 2.5 Pro by 9 points.
