Evaluation lab
The RAG palette on this site is only worth trusting if its evaluation is inspectable. This page publishes the whole thing: the questions, the scoring rules, every result, the retrieval numbers, the adversarial cases, and how each run compared with the last. It is regenerated by npm run evals; nothing on it is typed by hand.
- Retrieval
- cloudflare:@cf/baai/bge-m3@1024, cosine similarity over the site's chunks, top 8, threshold 0.42. Calibrated on 15 Sep 2026 for bge-m3: on-topic questions score at or above 0.44, off-topic ones at or below 0.37 (on gemini-embedding-2 the same gap sat at 0.65 and 0.55, threshold 0.60).
- Generation
- groq/openai/gpt-oss-120b, gemini-3.5-flash-lite with a JSON response, temperature 0.2, prompt version p4. The prompt allows only the numbered sources, requires a citation on every factual sentence, and returns NOT_ON_SITE when nothing applies.
- Cost
- Free tiers only: Cloudflare Workers AI for embeddings (10,000 neurons a day; the whole index costs about 250), Groq for generation (30 requests a minute, low reasoning effort), Gemini as the fallback. Per answer, the mean is 1359 prompt and 111 output tokens. The eval runner caches query embeddings so a re-run spends nothing on retrieval.
- Not claimed
- The "similarity" figure shown under an answer is the mean cosine score of the chunks used. It is not a calibrated probability of correctness and is not reported as one.
Grounding
At least one citation points at an expected source, and every citation is an expected source or a general one about him (profile, changelog, testimonials, and the writing, which is derived from the case studies). Retrieval is scored separately: was an expected source in the top 8 above threshold (recall@8), and how high (MRR).
passHas he handled payment webhooks in production?rank 1 · 4364 ms

passWhat is Notify?rank 1 · 2782 ms
Notify is a multi-tenant notification service built in Java 21 with Spring Boot 3.5, RabbitMQ and PostgreSQL that processes one incoming event into separate jobs for each matched channel such as in-app, email (via Resend) and push (via Firebase) [1][2]. It stores events in Postgres as the source of truth, uses RabbitMQ as a courier, and a delivery worker polls every 5 seconds in batches of 50 to send notifications [1][3].
