A roundup of AI industry news compiled by zhichai.net's Easy AI Daily, covering business moves, policy and safety, model capabilities, agent tooling, infrastructure, and research.

Business & Companies

• OpenEvidence raises $250M at $12B valuation: The "ChatGPT for doctors" completed a $250M round — roughly 12x its October 2025 valuation of $1B. The CEO says ~40% of US doctors use it, with revenue topping $100M last year (about 120x price-to-sales). CNBC
• Podium's "AI employees" pass $100M ARR: The SMB SaaS company grew its customer-service/sales agent business from 0 to $100M ARR in 21 months, with 10,000+ deployed AI employees handling missed calls and after-hours leads. Burn reportedly fell from $95M to zero. Founder thread
• Runpod hits $120M ARR: The developer-focused GPU cloud, which started as a Reddit post on /r/LocalLLaMA, reached $120M ARR four years after launch. TechCrunch
• Lightning AI merges with Voltage Park: Co-led by Lightning CEO William Falcon and former Voltage CEO Ozan Kaya, widely read as a reverse merger combining compute with an MLOps stack to compete with Runpod. Announcement
• GPU price war: Voltage promises 8×A100 80GB at $6/hr and 2×RTX 5090 at $0.53/hr in 2026, claiming up to 80% cheaper than AWS/RunPod/Vast.ai; Spheron AI launched a marketplace claiming 40–60% savings on H100/H200/B200.
• Greg Yang moves to advisory role at xAI due to long-term Lyme disease fatigue; the community is concerned about impacts on xAI's theoretical research direction. Announcement

Policy, Governance & Safety

• Anthropic releases Claude's constitution as CC0 open source: The values/behavior document is stated to be directly used in training; the community debates whether it's a practical harm-reduction tool or "alignment theater," and the circularity of training a model on a document describing its own behavior. Release post
• Jailbreaking communities keep probing Gemini and Grok: BASI prompt chains like "Project Shadowfall" got Gemini to explain pass-the-hash attacks (members pointed to Google Bughunters for bounties); Grok seen as stricter, with members attempting third-party API token workarounds.
• Adversarial attacks on AI text classifiers: Eleuther community shared practical attacks and "adversarial models" that fool AI-writing detectors, while acknowledging Pangram's detection research holds up at scale. Blog post

Models & Capabilities

• AirLLM claims 405B on 8GB VRAM: Layer-by-layer streaming inference (with optional compression) reportedly runs Llama3.1-405B in 8GB and 70B in 4GB VRAM — viewed as an extreme paging experiment demonstrating "it can run," not a production setup.
• Gemini 3: Strong education push (SAT practice with The Princeton Review, Writing Coach with Khan Academy) alongside frequent image/video generation failures on LMArena and OpenRouter — "capable but unstable."
• GPT-5.2: Thinking mode runs 20–30 minute reasoning chains; leaked GPT-5 mini pricing around $0.25/M input tokens, seen as a strong value option versus Haiku 4.5 and Gemini 3 Fast.
• Agent benchmarks far from human-level: Google's APEX-Agents long-horizon Workspace tasks — Gemini 3 Flash High Pass@1 at 24%, GPT-5.2 High at 23%, Claude Opus 4.5 at 18.4%. The prinzbench legal-retrieval benchmark shows search as the main weakness; GPT-5.2 Thinking barely passed 50%, some Claude variants scored 0/24 on search. APEX results
• GLM-4.7-Flash integration failures: FlashAttention falling back to CPU, extreme slowness (down to 2.8 tok/s), infinite loops. Fixed via a llama.cpp PR; the model was re-uploaded on Hugging Face with corrected configs — a textbook case of model + inference stack misalignment.

Agents & Tooling

• Prefect Horizon: An enterprise "context layer" over MCP with managed deployment, tool registries, gateways, RBAC, and audit logs — MCP defines the protocol, not how to run it safely in a company. Intro
• LangChain Agent Builder GA + Deep Agents: Agents packaged as organized folders of files — downloadable and runnable locally or in the cloud; sub-agents used for context isolation.
• MCP vs Skills: Hugging Face's Phil Schmid argues the problem is poorly designed MCP servers, not the protocol — design for outcomes, strongly typed flat parameters, error messages written for agents. Skills and MCP are complementary. Thread
• Devin Review: Cognition's AI tool for reading PRs — reorders diffs by importance, flags duplicated/pasted code, enables per-hunk chat, accessible via devinreview.com or npx.
• GitHub Copilot CLI adds askUserQuestionTool: The CLI agent now asks clarifying questions (e.g., how to handle rebase conflicts) before acting — command-line AI evolving toward conversational agents.

Infrastructure & Hardware

• GPU kernel optimization as sport: Anthropic's public performance takehome (optimizing a VLIW micro-machine kernel) got human and AI attempts — hand-written CUDA/Triton at 2200 cycles, Claude Opus 4.5 in Claude Code at ~1790 cycles. Problem repo
• PyTorch maintainers drowning in AI-generated PRs: Proposals to auto-filter with Claude/Pangram plus Cursor Bugbot + GPT-5 Pro triage before human review.
• AMD AI Bundle: The latest Adrenalin driver packages one-click installs of PyTorch, ComfyUI, Ollama, LM Studio, and Amuse for Windows, lowering the bar for local AI on AMD GPUs. AMD blog
• Used GPU prices soaring: Used 3090s near €850 on eBay; a 5090 bought at £2000 now listed at £2659.99 — local-model GPUs have become quasi-assets, signaling persistent compute scarcity.
• NVIDIA ecosystem deep-dives: Blackwell warp/TMA utilization, NCCL all-reduce pipelining across nodes, nvshmem as a communication alternative, and HBM capacity as a real bottleneck alongside FLOPs. NCCL issue

Products & Applications

• Google × Khan Academy Writing Coach: Gemini guides students through drafting and revision rather than writing for them, positioned as an education tool. Announcement
• Runway Gen-4.5 image-to-video: Emphasis on character consistency, camera motion, and narrative continuity — evaluation shifting from single-clip quality to multi-shot storytelling. Release
• LMArena: Text Arena surpassed 5 million votes; Video Arena opened on the web with 3 generations/day in battle mode. Video Arena
• Multi-model desktop apps: Inforno (chat with multiple LLMs, .rno history files) and Soulbotix (virtual-avatar Windows client running local Whisper on RTX 4070Ti-class GPUs).
• AI adult content: AI-generated virtual personas are competing with human creators, forcing a shift toward IP, interaction, and offline experiences.

Research & Methods

• DSPy RLM: Reframing agents as callable programs — large files stored in Python variables and manipulated via function calls, turning context management into a coding problem.
• Multi-vector retrieval: Mixedbread claims a 17M-parameter ColBERT-style model beats 8B-parameter single-vector embeddings on long-document benchmarks, serving 1B+ docs at p50 < 50ms; TurboPuffer markets ANN indexing at 100B-vector scale.
• NVIDIA TTT-E2E: Treating long context as online weight updates so inference time scales with steps, not context length — trading off precise needle-in-haystack recall.
• Cute/CUTLASS layout algebra: A categorical-foundations treatment of shape/stride constraints argues kernel authors need formal layout algebra intuition. Blog

Community Notes

• LM Studio: GLM-4.7-Flash crashes post-runtime update; users note no "GPT-4-style jump" since Qwen3 and are watching the 100–200B open-model space.
• Manus.im complaints: Only 20 of 38 user-built modules still working, Manus 1.6 regressions, and a $42 upgrade's promised 8,000 credits not arriving — worrying signals for an engineering-agent product.
• Coderrr: An open-source Claude Code alternative with project-level understanding, welcoming issues and PRs. GitHub
• Aider's future questioned: Slow updates spur fears the project is dying; the community Aider-CE fork is adding MCP and agent capabilities.
