Is there any industry that won’t be affected by AI at all?
A 45M parameter model competing with 230M–270M models sounds ridiculous. But that’s exactly what Needle 2 claims to do. Needle 2: • 45M parameters • 14MB single binary • 2-bit quantized • Built for tool calling, device use, and structured extraction Compared with FunctionGemma 270M, LFM2.5 230M, and Apple’s on-device foundation model, Needle 2 reportedly trades wins while using a footprint that can be 5–70× smaller than FP16 alternatives. That may be the real story here. The future of edge AI may not be about making models bigger. It may be about making them small enough to run everywhere. #AI #LLM #EdgeAI #OnDeviceAI #SmallLanguageModels
What is Jev? Imagine you have a super-fast AI helper. You give it some information and ask a simple question like: “Is this spam?” “Which group does this belong to?” “Should we do A or B?” Jev looks at the information and makes a decision. ChatGPT is good at talking and writing. Jev is designed to be good at choosing and judging. It’s kind of like an AI-powered if statement for your program. ⚡ Input → Jev → Decision Simple, fast, and easy for software to use. #AI #Jev #Programming #ArtificialIntelligence

LLMs are great at language. But enterprise AI needs structure. Ontology defines the schema, relationships, and meaning behind your data. Think of it like: Ontology = semantic schema Knowledge Graph = connected data LLM = natural language layer This is where RAG and AI Agents get much more powerful. #AI #LLM #Ontology #KnowledgeGraph #RAG
A user clicks “Pay” twice. Your API receives both requests. How do you prevent a double payment? A) Validation B) Idempotency key C) JWT D) Redis What would you choose — and why? 👇 #Backend #API #SystemDesign #WebDevelopment #Programming

@upmills_0106 ありがとうございます。よろしくお願いいたします。
20年以上エンジニアをして感じること。 AIで「コードを書く時間」は確実に減った。 でも逆に、 ・設計する力 ・要件を分解する力 ・AIの出力をレビューする力 ・障害原因を切り分ける力 価値は上がっています AI時代ほど「正しく判断できるエンジニア」が強い。 AI×Web開発の実践を発信していきます。
