Our VP of Engineering, Xiaofan(James) Luan, was supposed to buy his wife a Dior bag for their anniversary.  Instead, he bought three Claude Code subscriptions and spent the holiday trying to cross-compile 2 million lines of C++. Every fix on one platform broke two others.  $600 later, the only output was "git reset --hard" — and a very cold dinner table.😂 "Make it compile on Windows" is a trap. The real goal was "compile everywhere without hacks" — no AI is going to figure that out for you at 2 am. What worked: constraints before code, review tests not code, bottom-up, one layer at a time. Same task, two days. Then he ran six parallel Claude sessions across three machines with git worktree. The bottleneck stopped being intelligence and started being how fast one person can alt-tab. AI solves exactly the problem you give it. Engineering is in knowing which one to give. His wife is still waiting for that bag.

We (w/ Shansan Gong, Ruixiang ZHANG, Huangjie Zheng, Jiatao Gu, Navdeep Jaitly, Lingpeng Kong) released a family of 7B diffusion language models, DiffuCoder, that specializes on code generation, with a focus on understanding and improving masked diffusion models. A core analysis of DiffuCoder is the autoregressiveness (AR-ness) score, a novel metric that quantifies the causal patterns in decoding, revealing how diffusion models break from strict left-to-right generation for more flexible, non-linear code planning. Recent advances in autoregressive (AR) models dominate code generation, but diffusion-based LLMs (dLLMs) like DiffuCoder offer a promising alternative, especially for complex programming tasks. DiffuCoder explores how these models decode differently—showing less global AR-ness in code tasks compared to math—and how temperature affects both token selection and generation order, unlike traditional AR models. We also introduce coupled-GRPO, a post-training RL method with a coupled-sampling scheme, to reduce performance drops during accelerated decoding, boosting parallelism and efficiency. We use a self-improvement pipeline that leverages AR-ness analysis, coupled-GRPO optimization, and evaluation on benchmarks like AceCode-89k to refine decoding strategies. This approach enables DiffuCoder to navigate diverse code generation pathways and enhance performance with modest computational overhead. Looking ahead, we aim to further leverage Reinforcement Learning to steer code generation through these decoding patterns, with the discrete nature of AR-ness scores providing a foundation for search-based strategies—ideal for the sparse rewards of optimizing complex code structures.

We developed an open-source AI tool to design concrete mixes that are stronger, more sustainable, and ready to build with faster—speeding up construction while reducing environmental impact. https://lnkd.in/gPCk8tCM But the impact of this AI tool is not just hypothetical! Amrize used Meta’s AI-based technologies to design a new low-carbon mix, and successfully deployed it in an at-scale slab-on-grade application at Meta's new data center in Rosemont, MN. Compared to the legacy mix, this new AI-designed mix is: 🦁 Stronger ⏱ Faster 🍃 Lower carbon ⏱ ️The ideal set time All this was achieved without needing any new materials, nor special equipment. Best of all, the AI is open-sourced. https://lnkd.in/g2KA7KZW This work was featured in a Meta engineering blog article published today! https://lnkd.in/gBU9HY8H

Anysphere, a three-year-old San Francisco startup that makes the AI-powered coding assistant Cursor, raised $900 million at a $9.9 billion valuation, reports Bloomberg, confirming a scoop by the Financial Times last month. The deal was led by Thrive Capital, with Andreessen Horowitz, Accel, and DST Global also opting in. https://lnkd.in/gtYGEPFu

At Ray Summit 2025, Elizabeth Hu, Goku Mohandas Mohandes and Akshay Malik from Anyscale will announce Lineage Tracking on Anyscale, a new observability tool for end-to-end ML lineage powered by OpenLineage. It maps datasets and models across Workspaces, Jobs, and Services and renders an interactive lineage graph for fast reproduction, audit, and debugging. It also integrates with your existing catalogs and registries like MLflow, Weights & Biases, and Unity Catalog. What you will learn: - How OpenLineage automatically captures datasets, models, code versions, and parameters across development to production on Anyscale - How to navigate the lineage graph to reproduce runs, trace failures upstream, and support governance and audits - How to connect lineage to MLflow, W&B, and Unity Catalog to keep one source of truth for artifacts and metadata Nov 3–5 at the San Francisco Marriott Marquis. Register now: https://lnkd.in/ghAANMa6

Run Claude Code Locally on Apple Silicon Using LM Studio and LiteLLM (Zero Cost) In this blog, Manjunath Janardhan walks us through how to run Claude Code locally on Apple Silicon using LM Studio + LiteLLM + Qwen3-Coder-30B — with zero API cost and no cloud dependency. The setup uses: - LM Studio for local inference - Qwen3-Coder-30B as the coding model - LiteLLM as a bridge between Claude Code and a local OpenAI-compatible endpoint This is a practical way to get the Claude Code experience fully offline on macOS, especially for M-series Macs where MLX models can make a real difference. Worth reading if you want to run agentic coding tools on your own machine without relying on the cloud. Read it from the comments!
