Use GPT-4o privately on Venice
Running GPT-4o on Venice ensures your prompts are never stored or profiled — only anonymized metadata is retained. You access the same model OpenAI offers, but with privacy-first infrastructure: no training retention, no user tracking. This means enterprise-grade AI with zero prompt retention, ideal for sensitive workflows.
What can GPT-4o do?
- •Real-time responsiveness — audio response latency as low as 232ms, comparable to human conversation.
- •Multimodal fluency — excels at vision and audio understanding, with strong cross-modal reasoning.
- •High performance across languages — significant improvements in non-English text tasks over prior models.
- •Efficient and fast — 50% cheaper than GPT-4 Turbo in API costs while matching its English and code performance.
- •Not open-source or self-hostable — fully proprietary with no open weights available.
- •No end-to-end encryption or TEE protection on Venice — privacy is anonymized, not encrypted in transit or at rest.
- •Video input and output not supported despite 'omni' branding — currently limited to image input and text output.
