We benchmark LLMs at PostHog on practical tasks with real data

Comments on “We benchmark LLMs at PostHog on practical tasks with real data”

3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked

PostHog describes how it benchmarks its LLM agents on real tasks, including its ReviewHog code review agent and Scouts, its scheduled research agent. It covers three evaluation approaches of rising complexity: checking against bugs from a single PR, a 33-incident golden set built from real past incidents, and tailored rubrics…

Why it ranked

No. 35 of 127 with a score of 0.67. The panel rated it highest on practical relevance (0.83) and technical depth (0.82), lowest on significance (0.54). Placed No. 35, No. 26 by score alone: the seventh AI & machine learning story of the day (−0.080). The placement terms move stories; they are not part of the score.

AI judgeJudge 2claude-haiku-5-5
Detailed, practical engineering write-up on benchmarking LLM agents with real data and isolation pitfalls. Strongly on-topic for builders; fairly substantiated by internal experiments, though it is a company blog with limited external verification.
AI judgeJudge 3gpt-5.6-luna
Detailed first-party engineering lessons on benchmarking agentic systems, grading subjective tasks, preventing state leakage, and building reproducible frozen environments, with concrete internal results and implementation tradeoffs.

Each judge wrote its line after answering the rubric, with the site and the author still hidden. Every answer behind this is in the table under Score.
