Summary

Easy AI Daily for June 23, 2025 covers major AI developments across models, research, industry, and hardware. Sakana AI introduced Reinforcement Learning Teachers (RLTs), 7B models that teach Chain-of-Thought to larger models. Mistral shipped Small 3.2 with better instruction following and FP8 support, while Google released Magenta RealTime, an 800M-parameter open model for real-time music generation runnable on free Colab. Arcee AI launched the 4.5B AFM foundation model, OpenThinker3-7B claimed a 33% improvement over DeepSeek-R1-Distill-Qwen-7B, and STORM compressed video inputs 8x to beat GPT-4o on MVBench. In industry news, Harvey AI raised $300M at a $5B valuation, Replit's ARR passed $100M, and ElevenLabs launched the MCP-enabled 11ai voice assistant. The roundup also compares PPO vs GRPO, covers spectral clipping optimization, n8n automation tutorials, AMD Ryzen AI Max 395 running 70B+ models, and Yuval Noah Harari's warning that AI is like billions of digital immigrants arriving visa-free.

Easy AI Daily | June 23, 2025

A roundup of AI industry news for June 23, 2025, covering model releases, research advances, funding, tools, and hardware.

Model Releases and Updates

  • Sakana AI Reinforcement Learning Teachers (RLTs): Trains 7B models via reinforcement learning to generate step-by-step explanations that accelerate Chain-of-Thought learning in larger models — the small model acts as a "teacher" rather than the LLM being trained directly. Details
  • Mistral Small 3.2: Improved instruction following and function calling, experimental FP8 quantization; tool calling in GGUF/transformers largely fixed. Update
  • Google Magenta RealTime: 800M-parameter open model for real-time instrumental music generation from mixing parameters; runs in free-tier Colab; claimed as the first open real-time music generation model. Project | GitHub | Demo
  • Arcee AI AFM-4.5B: 4.5B-parameter foundation model built by extending Llama 3, five months in development, targeting sub-10B scenarios. Blog
  • OpenThinker3-7B: New open 7B reasoning model, +33% over DeepSeek-R1-Distill-Qwen-7B on reasoning benchmarks. Release
  • STORM text-to-video: Inserts Mamba layers to compress video inputs 8x; scores 70.6% on MVBench, surpassing GPT-4o; combines SigLIP vision encoder with Qwen2-VL. Highlights
  • OmniGen2: Open image editing model based on Qwen-VL-2.5 (an open Flux.1 Kontext alternative), with decoupled text/image decoding paths, no flash-attn required; strong single-image editing, good multi-image editing, beating OmniConsistency and BAGEL. Project | GitHub | Hugging Face
  • Research and Algorithms

  • PPO vs GRPO: PPO uses clipped objectives and a value model for stable general-purpose learning; GRPO removes the value model and normalizes rewards within groups, better suited to reasoning-heavy tasks. Analysis
  • DINOv2 on ImageNet-1k: Aggressively optimizing k-nn accuracy on ImageNet-1k suggests overfitting evaluation metrics can still yield better generalizing models. Analysis
  • Spectral clipping: New optimization technique that caps singular values (e.g., values above β=8 set to 8), unlike Muon which pushes them toward 1; improves stability. Blog
  • Torchtune dataset packing: Fixes OOM issues from packing, supports pre-tokenized packed datasets, dynamic packing planned to speed reasoning-model training. PR #2819
  • Industry and Funding

  • Harvey AI: $300M Series E at a $5B valuation, led by Kleiner Perkins and Coatue, for R&D and market expansion. Announcement
  • Replit: ARR surpassed $100M, a 10x increase since end of 2024. Announcement
  • ElevenLabs 11ai: Voice-first AI assistant supporting MCP, integrated with Perplexity, Linear, and Slack. Product
  • MCP Validator: New release supports the 2025-06-18 MCP spec, adding OAuth 2.1 auth, structured tool output, and GitHub Actions compliance templates. GitHub
  • Tools and Platforms

  • Unsloth: Fixed Gemma 3 8-bit/4-bit quantization RuntimeError; users should upgrade unsloth-zoo and unsloth, with PyTorch 2.7cu12.6 recommended.
  • Cursor: New pricing caused rate-limit confusion; some users report Gemini 2.5 Pro looping/verbosity issues and suggest switching to Sonnet 4. Pricing
  • Chisel CLI: Profiles AMD MI300X via cloud servers at $1.99/hour, auto-syncing code and running rocprof. GitHub
  • Notebook LM: Now indexes and retrieves images (charts, figures) from PDFs.
  • Tutorial: Getting Started with n8n

    An 8.5-hour n8n video tutorial is recommended; the first 1.5 hours cover the basics. Prerequisites include:

    1. Basic skills: Flowchart/swimlane diagramming; experience with event-triggered tools (Axure, IFTTT, iOS Shortcuts, RPA). 2. Data basics: Data types (numbers, dates, strings, arrays, binary files) and JSON. 3. API concepts: GET/POST, API keys, cURL — no deep technical knowledge needed. 4. Prompting knowledge: system prompt vs user prompt for AI chat nodes. 5. Agent structure: Chat + Memory + Tool for configuring Agent nodes.

    Use cases: automated social media posting and customer email replies, batch image generation/editing, and cloud file management (invoice organization, document classification). Note that better tools may exist for some scenarios.

    Ecosystem contrast: Overseas markets enjoy a thriving open-API ecosystem with companies and intermediaries of all sizes; domestic (China) users tend to rely on full-suite services from large platforms.

    AI and Society

  • Yuval Noah Harari compared the AI revolution to billions of "digital immigrants" arriving visa-free at light speed, disrupting jobs and power structures; he called for attention to governance challenges. Talk
  • Mechanize trains AI agents in simulated environments for professional skills (engineering, law), aiming for a "fully automated economy." Intro
  • AI code quality debate: Developers report inexperienced teams producing low-quality AI code that inflates maintenance needs and demand for senior engineers, though tools like Claude Code may improve this. Discussion
  • Hardware and Optimization

  • Blackwell B200 / RTX 5090: Both run Gemma 3 stably; the B200 nearly exhausts VRAM training a 27B model; 5090 pricing in Europe dropped to about €2,200.
  • AMD Ryzen AI Max 395: With 128GB LPDDR5x, runs 70B+ models in LM Studio at 3–4 tokens/second; memory allocation needs driver improvements. Demo
  • Neutrino: Open-source eBPF-based GPU kernel-level profiling tool with assembly-level probing and memory access visualization, accepted at USENIX OSDI '25. GitHub
  • Community and Open Source

  • Arch-Agent-7B: 7B model scores 69.85 on multi-step agentic workflows, surpassing GPT-4.1 (68.89); strong at function calling and complex task planning. Model card
  • Sherlog-MCP: IPython-based shared workspace enabling multi-agent collaboration with persistent results, sidestepping context window limits. GitHub
