## Worth attention

- **langchain==1.4.0a3 — new langchain.mcp namespace**
  https://github.com/langchain-ai/langchain/releases/tag/langchain%3D%3D1.4.0a3
  LangChain 1.4's third alpha introduces a dedicated langchain.mcp namespace: an MCPAdapter that wraps any fastmcp.Client (URL, script, in-process server, multi-server config, or ClientGroup) into LangChain tools, with client-side tool-list caching. This is LangChain formalizing first-class MCP support rather than leaving it to third-party glue.
- **Show HN: Running a 125B-parameter model on a 48GB Mac**
  https://github.com/carloslfu/slotstream
  slotstream lets you run Qwen3.8-Flash-Next (a 125B-parameter MoE model that normally needs 100GB+ RAM) on Macs starting at 16GB, via expert-offloading/SSD-streaming, natively in Swift/MLX, reaching ~12 tok/s on a 48GB machine. Ships with an auto-mode that trades off memory vs. speed, with speculative decoding (MTP) planned next.
- **Ollama v0.33.3-rc0**
  https://github.com/ollama/ollama/releases/tag/v0.33.3-rc0
  Release candidate for Ollama 0.33.3: now honors GGUF-defined default sampling parameters, plus MLX/llama.cpp updates. Minor behavior change for anyone running local models with model-embedded defaults.
- **Google Pics — image creation/editing in Workspace**
  https://blog.google/products-and-platforms/products/workspace/google-pics/
  Google launched Google Pics, an image creation and editing tool built on its Nano Banana model, now available inside Google Workspace. It's a consumer/productivity feature rather than a developer API.
- **Publishing pricing on day one (incl. $100 charity tier)**
  https://www.reddit.com/r/SaaS/comments/1w4wjnl/we_published_our_pricing_on_day_one_including_a/
  A B2B SaaS founder describes publishing pricing publicly from launch ($200/$500/$100 tiers, two-month free trial, no card required) against the common advice to hide pricing behind a sales call. A concrete, specific pricing-strategy decision from a real (if early) launch.
- **@huggingface/kernels: 200+ WebGPU Kernels for Local AI**
  https://huggingface.co/blog/webgpu-kernels
  Title indicates Hugging Face released a library of 200+ WebGPU compute kernels for running AI locally (in-browser or on-device), but the fetched content body was empty so specifics (which models, performance, license) can't be confirmed here.
- **Introducing Neon Labs**
  https://neon.com/blog/introducing-neon-labs
  Neon launched 'Neon Labs,' described as a home for experimental tools built around its Lakebase Postgres product - positioned as a community playground. No specific tools listed yet in what was fetched.
- **Show HN: Weedout - hides YouTube AI-labeled videos**
  https://masteranza.github.io/weedout/
  A solo developer built and shipped a $1.99 Safari extension that hides YouTube videos labeled 'Made with AI,' using YouTube's own label rather than AI detection, running locally. Source is open on GitHub.
- **Cloudflare: saving petabytes of cache storage with Zstandard + Pingora**
  https://blog.cloudflare.com/cache-transcoding/
  Cloudflare describes prototyping in-cache compression (Zstandard) inside their Pingora-based cache layer to fit more cached content on the same hardware, potentially saving petabytes of storage at their scale.
