AI evals can be wild . Q: What day was yesterday?.LLM: Yesterday would be April 14, 2025.LLM eval: ❌ ERROR - the answer says "April 14, 2025" instead of "2025-04-14". The claim says "ignore formatting" . SO I SHOULD HAVE ANSWERED "SUCCESS" INSTEAD🤪

Inspired by @JamesWard and @starbuxman “Building Agents with AWS” demo, I gave Spring AI and Evaluation Testing a try. Cool stuff, but getting evals right can be tricky! 😅👉

Me: hacking with SQL Injection a dummy site intentionally made vulnerable for learning purposes 🤓. Real hackers: let me open this $3000 mac book pro and try electro-magnetic fault injection into one chip to see if it skips a few instructions of code 🤯.

Love #ChatGPT simultaneous smartness and dumbness . asked it why a regex does not work and answers ". due to the way regex capturing groups work, only the last match in a repeating pattern is captured" 😍 then contradicts itself giving a solution that does not work either 😅

I tried a few times and another solution for the multiple ports specification was to configure two rules . 🤓 There is a way to use 2 ports in the same rule.🤖 You're right . Nice save by #ChatGPT4 👏

Don't know if @OpenAI #chatgpt4 is smart but it sure looks like it . 🤓 Send a payload of a specific size using curl.🤖 To send a payload of a specific size using curl . 🤓 This will not work for big payloads.🤖 You're correct . command line length / memory limitations 😲👇
