Ask HN: Would you pay for an AI API that guarantees zero prompt retention?
A developer proposes a privacy-first OpenAI-compatible API service built on open-weight models Core promise: zero data retention — no logging of prompts, completions, or request/response content Only operational metadata retained for billing: request ID, model, token counts, latency, and timestamps The idea is still in the validation phase; the author plans to test with a consumer GPU (RTX 5090) before committing to infrastructure
Analysis
TL;DR
- A developer proposes a privacy-first OpenAI-compatible API service built on open-weight models
- Core promise: zero data retention — no logging of prompts, completions, or request/response content
- Only operational metadata retained for billing: request ID, model, token counts, latency, and timestamps
- The idea is still in the validation phase; the author plans to test with a consumer GPU (RTX 5090) before committing to infrastructure
Why It Matters
This highlights a growing demand for privacy-preserving AI inference among developers and organizations handling sensitive data. As regulatory scrutiny around AI data practices increases, services that guarantee zero retention could fill a meaningful niche in the market.
Technical Details
- The proposed service would expose an OpenAI-compatible API endpoint, enabling drop-in replacement for existing integrations
- Open-weight models would be hosted server-side, eliminating the need for users to manage local inference
- Data retention policy strictly limits stored information to billing and operational metadata (request ID, model name, input/output token counts, latency, timestamp)
- No prompts, completions, or request/response payloads would be logged or stored
- Initial proof-of-concept would run on consumer hardware (RTX 5090) with a small open-weight model before scaling
Industry Insight
- Privacy-first AI inference is an underserved segment; competitors who ship this capability first could capture enterprise and privacy-conscious developer audiences quickly.
- Running open-weight models on consumer GPUs for early validation is a cost-effective strategy, but production-grade latency and throughput will require significant infrastructure investment.
- The "zero retention" guarantee is a strong differentiator but introduces operational complexity around logging, debugging, and abuse prevention that the author has not yet addressed.
