"Benchmarking local LLMs for enterprise use: what I learned comparing Ollama, vLLM and llama.cpp" by zahra Zhar
Benchmarking local LLMs for enterprise use: what I learned comparing Ollama, vLLM and llama.cpp
How I compared four open-source LLMs on enterprise tasks using Promptfoo, an LLM judge and response-time monitoring, and what I learned about serving them locally.

Stop eyeballing! Use 'Evals' to catch regressions. Tools like Promptfoo let you run automated test suites against tweaks. Pair with Pydantic for strict schemas. Treat prompts like code—version them and test against a gold dataset.

Reliability usually breaks at the eval step: without a fixed golden set, a prompt tweak fixes one case and silently regresses others. promptfoo is one open-source harness for it. Does the article cover evals, or stay on infra and retries?

Hoy las evals de la plataforma de OpenAI pasan a sólo lectura. El 30-nov se apagan el dashboard y la API de Evals. Si tu equipo tiene evals ahí, exporta este mes. OpenAI publicó una guía para pasarse a Promptfoo.

OpenAI Evals go read-only today and shut down Nov 30. OpenAI's move guide has no export step.
My script saves every eval, run and output item, plus a promptfoo grader map. On a fake API and model, 40 of 40 checks matched.

OpenAI Evals shutdown: save your evals and runs before November 30, then move them to promptfoo
OpenAI Evals go read-only Oct 31 and shut down Nov 30, 2026, with no export button. A tested script saves every eval and run; a grader map moves them.

Introduction: Large Language Model (LLM) applications are increasingly vulnerable to sophisticated prompt injection and secret exfiltration attacks that bypass standard instruction tuning. Setting up a local red-teaming lab using frameworks like Promptfoo and FastAPI enables developers to proactively identify security gaps before deployment.

openai killed its evals platform and bought promptfoo, meanwhile my rag pipeline's entire eval suite is a spreadsheet called final_v2 and some vibes. guess i know what this weekend looks like

A spreadsheet is a fine start honestly. Moving 30 or so real questions, each with the doc that should come back, into promptfoo is a doable weekend job, and it'll tell you if the chunking fix holds.

拿一句话练习摘要：

摘要：“项目将于下周上线。”
句子很顺，试点却变成上线，未决定变成确定。把这样的错留作测试题，换提示词后再跑一遍，比只看语气有没有更好更实在。
