Teenager builds self-hosted AI drift proxy to detect LLM changes

By PulseAugur Editorial · [1 sources] ·

A 15-year-old developer has created Wallras, a self-hosted AI drift detection proxy designed to identify silent changes in LLM behavior. The tool operates with minimal overhead and keeps all data on the user's servers, addressing privacy concerns associated with third-party observability platforms. Wallras employs advanced statistical methods like Population Stability Index and Jensen-Shannon Divergence to detect drift, and analyzes token log probabilities to identify confident hallucinations. It also includes robust data deletion capabilities for SQLite databases, ensuring compliance with regulations like GDPR by overwriting deleted data and crypto-shredding salts. AI

IMPACT Enables developers to monitor LLM behavior and data privacy without relying on third-party services.

RANK_REASON The item describes a self-hosted proxy tool for detecting AI model drift, not a new model release or core research.

    How I built a 3ms self-hosted AI drift proxy in Python (and wiped deleted prompts from SQLite WAL files)

    <p>If you run LLMs in production—whether OpenAI, Anthropic, Gemini, or self-hosted Ollama/vLLM—you have probably been burned by <strong>silent model drift</strong>. An upstream provider tweaks quantization or safety filters overnight, refusal rates jump, or an update subtly break…
