## Worth attention

- **Hackers Simply Asked Meta AI to Give Them Access to High-Profile Instagram Accounts. It Worked**
  https://simonwillison.net/2026/Jun/1/hackers-simply-asked-meta-ai/#atom-everything
  Hackers demonstrated they could socially engineer Meta AI into granting access to high-profile Instagram accounts through simple conversational prompts. Verified from multiple sources. This is a serious AI security vulnerability — any AI assistant with account management capabilities is a potential attack surface. If you integrate AI with authenticated systems, audit your access controls.
- **[AINews] NVIDIA Cosmos 3, Nemotron 3 Ultra, and RTX Spark**
  https://www.latent.space/p/ainews-nvidia-cosmos-3-nemotron-3
  Major NVIDIA Computex announcements: Cosmos 3 (omnimodal world model, open weights on HuggingFace in 16B/64B variants), Nemotron 3 Ultra (frontier reasoning model), and RTX Spark (compact desktop AI box with NVLink). Cosmos 3 is notable for open weights covering text-to-image/video/audio. RTX Spark bandwidth claims need verification (see correction item).
- **RTX Spark does not have 600GB/s Bandwidth**
  https://www.reddit.com/r/LocalLLaMA/comments/1tu639j/rtx_spark_does_not_have_600gbs_bandwith/
  Important correction: NVIDIA's RTX Spark 600GB/s figure reported by every outlet is actually the NVLink speed, not memory bandwidth. Confirmed by Computex slides. If you're evaluating Spark for local inference, the actual memory bandwidth will be significantly lower than widely reported.
- **Introducing Mellum2: A 12B Mixture-of-Experts Model by JetBrains**
  https://huggingface.co/blog/JetBrains/mellum2-launch
  JetBrains released Mellum2, a 12B parameter MoE model designed for code intelligence tasks. Built by the makers of IntelliJ/WebStorm with unique IDE usage data. Open weights on HuggingFace. Potentially relevant for IDE-integrated code completion.
- **Qwen 3.7 Plus now available on Vercel AI Gateway**
  https://vercel.com/changelog/qwen-3-7-plus-now-available-on-ai-gateway
  Qwen 3.7 Plus and 3.7 Max are free for paid Vercel AI Gateway users until June 4, 2026 12:00pm PT. The model combines vision and language capabilities. Brief free window worth testing if you use Vercel's AI Gateway.
- **Vercel Blob now supports OIDC authentication**
  https://vercel.com/changelog/vercel-blob-now-supports-oidc-authentication
  Vercel Blob now defaults to OIDC authentication for new projects, replacing long-lived BLOB_READ_WRITE_TOKEN with short-lived, auto-rotating tokens. A meaningful security upgrade. If you use Vercel Blob, migrate away from static tokens.
- **Moss TTS 1.5 8B voice cloning examples**
  https://www.reddit.com/r/LocalLLaMA/comments/1tuh5ko/moss_tts_15_8b_examples_it_is_the_currently_best/
  Builder reports Moss TTS 1.5 8B is the current best open voice cloning model for English, beating Fish Audio S2 Pro and Qwen 3 TTS. Quality improves with output duration and temperature tuning. Relevant for anyone building voice agents with local TTS.
- **Simon Willison: Pasted File Editor**
  https://simonwillison.net/2026/Jun/2/pasted-file-editor/#atom-everything
  Simon Willison built a Pasted File Editor tool using Codex, inspired by Claude's feature of auto-detecting large text pastes and converting them to file attachments. A small but practical workflow tool for anyone doing heavy LLM-assisted editing.
- **Elastic Build Machines now protect against out of memory builds**
  https://vercel.com/changelog/elastic-build-machines-now-protect-against-out-of-memory-builds
  Vercel build machines now auto-scale to prevent OOM failures. Conservative thresholds balance reliability and cost. Useful if you hit OOM during builds.
- **Stop asking what model to run. There are literally only two.**
  https://www.reddit.com/r/LocalLLaMA/comments/1tu82wi/stop_asking_what_model_to_run_there_are_literally/
  LocalLLaMA community consensus is consolidating around Qwen 3.6 (35B and 27B variants) as the only viable local models worth running. Hyperbolic but reflects real market consolidation in the local LLM space.
- **Intel Arc Pro B70 llama.cpp benchmarks posted**
  https://www.reddit.com/r/LocalLLaMA/comments/1tuik6o/intel_arc_pro_b70_llamacpp_benchmarks_posted/
  Benchmarks for Intel Arc Pro B70 running llama.cpp with SYCL backend. Performance data for an alternative GPU vendor in the local LLM space.
- **NVIDIA GB300 Grace Blackwell Ultra pricetags**
  https://www.reddit.com/r/LocalLLaMA/comments/1tu2x22/nvidia_gb300_grace_blackwell_ultra_pricetags/
  Retail pricing for NVIDIA GB300 DGX stations appearing on UK retailer Scan. Enterprise-tier pricing data for the latest Blackwell Ultra hardware.
