Ask HN: Anyone doing production image editing with image models? How?https://news.ycombinator.com/item?id=46721518Hey HN — I’m building an app where users upload “real life” clothing photos (ex. a wrinkly shirt folded on the floor). The goal is to transform that single photo into a clean, ecommerce-style image of the garment.One key UX requirement: the output needs to be a PNG with transparency (alpha) so we can consistently crop/composite the garment into an on-rails UI (cards, outfit layouts, etc.). Think “subject cutout that drops cleanly into templates.”My current pipeline looks like: 1. User-uploaded photo (messy background, weird angles) 2. User-upload is matched to “query” image (style target) + promptCurrently using Nano Banana) 4. Background removal model to get transparency and save as RGBA PNGThis works, but it feels hacky + occasionally introduces edge artifacts. Also, the generation model sometimes invents shadows/background cues that confuse the background removal step. It feels like the two steps are fighting one another.I’m trying to understand what “good” looks like in production

Surviving AIhttps://news.ycombinator.com/item?id=46720146What follows was written by ChatGPT 5.2 Instant and it reflects my conversation with it about the two articles linked below. Enjoy.Ego plays a complicated role in periods of technological change. It sharpens skill during stable eras, but it often hinders adaptation during inflection points.Two recent essays on AI and software engineering illustrate this tension clearly.Emir Ribic’s “From Craftsmen to Operators” https://dev.ribic.ba/the-rapid-evolution-of-software-engineer-s-roleRibic frames the rise of AI-assisted development as a loss of craft. He mourns the disappearance of deep, line-by-line problem solving and the sense of authorship that came with it. Engineers, in his telling, are becoming operators—prompting, reviewing, and assembling—rather than builders. The piece captures something real: pride in difficulty, satisfaction in mastery, and the joy of personally solving hard problems.But that pride is also where ego enters. What’s being lost isn’t just a way of working—it’s a for

Show HN: Grov – Multiplayer for AI coding agentshttps://github.com/TonyStef/GrovHi HN, I'm Tony.I built Grov (https://grov.dev/) because I hit a wall with current AI coding assistants: they are "single-player." The moment I kill a terminal pane or close a chat session, the high-level reasoning and architectural decisions generated during that session are lost. If a teammate touches that same code an hour later, their agent has to re-derive everything from scratch or read many documentation files for basically any feature implemented or bug fixed.I wanted to stop writing a lot of docs for everything just to give context to my agents or have to re-explain to my agents what my teammate did and why.Grov is an open-source context layer that effectively gives your team's AI agents a shared, persistent memory.Here is the technical approach:1. Decision-grain memory, not document storage: When you sync a memory, Grov structures knowledge at the decision level. We capture the specific aspect (e.g., "Auth Strategy"), the choice made ("JWT"), and the reasoning ("Stateless for

Show HN: I built an AI book recommender in 2 dayshttps://mynextbook.aiHi HN! I built this in ~2 days over the New Year's break, and it was the most fun I've had coding in a while...*Why I built it:* I was tired of generic listicles and recoms from Google Search, ChatGPT/Gemini, and Goodreads. I wanted something where I could say "a cozy mystery for a rainy weekend" or "something like Kafka but less depressing" and get actual niche results.*How it works:* - Describe what you're looking for in plain text (or voice) [https://mynextbook.ai/onboarding-books] - A RAG system, built using Gemini 2.5 Flash Lite + Exa search, finds personalized recommendations - Metadata is fetched from multiple sources - ~5-10 seconds from input to recs (5-10X faster with cache)*Stack:* - Next.js 14 / TypeScript on Vercel - Neon (Postgres) + Prisma - Gemini + Exa Search API - Built with Cursor + Claude Code, & AntiGravity (happy to discuss which was better for what)*Try it without signing up:* no sign-up required to explore*Bonus:* It also recommends movies and TV shows based on

But this picture clashes with everyday experience, where objects appear in definite locations and configurations, never in superpositions. To account for this, standard quantum the

Show HN: Agentic coding – a practical guide to building with coding agentshttps://agenticoding.ai/Agentic coding is getting a lot of attention, but most explanations stay abstract or stop at demos.This is a short, hands-on course on building with coding agents: how to structure agent loops, when autonomy helps vs hurts, how tools and memory are actually used, and where things tend to break in real projects.The course focuses on:* Practical agent loop patterns (plan → act → reflect and variants)* Tool use, context management, and guardrails* Common failure modes (hallucinations, drift, runaway autonomy)* Tradeoffs between control, reliability, and speedIt’s aimed at engineers who want to go beyond toy examples and actually ship things with coding agents. Not a framework, not a product — just structured lessons based on real-world patterns.Feedback and critiques welcome, especially from people already building agents in production.
