Just finished the Maven course “AI Evals For Engineers & PMs” by @HamelHusain & @sh_reya — it exceeded expectations. From error analysis to RAG, agents, and CI/CD, I now have a systematic toolkit to measure & improve LLM apps. Next cohort: maven.com/parlance-labs/… Don’t miss it.

GPT-5-* API 업데이트: - GPT-5 계열 모델 temperature을 지원 안함 - 모델 응답의 길이 3단계로 조절 - Minimal Reasoning: 추론 토큰을 최소화, 응답 속도 향상 - Freeform Tool Calling: JSON 없는 도구 호출 - Context-Free Grammar: 문법 규칙으로 출력 형식 제어 jihobak.github.io/blog/writing/2…

🤔 Spotted something weird with GPT-5 API usage... Looking at token consumption for simple "hi" input, I'm seeing reasoning tokens = 0, but the API is still outputting detailed reasoning summaries. Anyone else noticing this? What could be causing this anomaly? #GPT5 @OpenAI

RAG without guesswork. This course showed me how to improve systematically: retrieval, synthetic evals, segmentation, routing...The playbook survives model changes. Beyond relying on models,a systematic methodology is essential. Strongly recommand @jxnlco maven.com/applied-llms/r…

얼마전 까지 만해도, 나는 비트코인을 그냥 거래소에서 돈놀이 하는 상품 정도로 생각 했다. 비트코인 #BTC 에 대해서 공부하도록 동기부여를 해준 첫번째 질문은 '돈'이란 무엇 인가였다. 나뿐 만 아니라 많은 사람들은 그냥 사용만하지 돈이 무엇인지 화폐가 무엇인지 생각 해본적이 없다고 생각한다
