nullsink is a privacy-first proxy for large language models that allows users to access frontier or open-weight models without creating an account. Users can mint a prepaid key directly in their browser and pay with Monero or Bitcoin. The service goes above and beyond to operate without request logs to ensure user privacy and maintains compatibility with standard Anthropic and OpenAI SDKs.

nullsink 1.9.0: More reliable payments
This release focuses on making payments and their status easier to trust: - Payments remain trackable if a quote expires while funds are on the way. - Accidental duplicate quote requests are prevented. - Credit is only confirmed after a reliable balance check. - Payment and network failures now show clearer, more accurate messages. - The single-use payment-address guidance is clearer. Behind the scenes, we also introduced safer infrastructure upgrades with health checks and automatic rollback. Coming soon: support for Kimi K3 and improved caching for open-weight models.

nullsink v1.8: more models, Open WebUI, and a hardening pass
This release adds support for the new GPT-5.6 series (sol/terra/luna), with a refreshed rate card synced from models.dev. There's now a guide for wiring nullsink into Open WebUI (https://github.com/nullsink/nullsink/blob/main/docs/openwebui.md), including a drop-in Claude pipe function. nullsink deliberately ships no built-in chat UI — but if you'd rather not hand-craft raw API calls, this gives you a full chat interface pointed at nullsink. I've tested the guide end-to-end so it's a real, working alternative. Under the hood, we split the proxy and payments into separate processes and shipped a round of reliability and money-safety hardening. Beyond the immediate wins, the split is a step toward maximal privacy assurance — it's the groundwork for moving the proxy onto dedicated TEE-attested hardware. No account. No logs. Same as ever.

The anonymous LLM proxy concept is really clever - you get access to frontier models without giving up your API keys or personal data. The prepaid model means no surprise bills, which is great for developers experimenting with different mod
