Claude Mythos 5 designs better quantum circuits

Sciencepositive +0.7#science#anthropic#mythos#quantum#cryptography

Anthropic's STEM Fellows work shows Mythos 5 taking plain-language specs and beating published quantum circuit designs, sometimes by an order of magnitude.

What they showed / shipped

  • Anthropic: given plain-language instructions, Claude Mythos 5 designed quantum circuits that beat the best published ones, sometimes by 10x or more (x/@AnthropicAI).
  • Primary writeup: Designing more efficient quantum circuits with Claude (Anthropic Research).
  • Same day, Anthropic also published Claude reveals ECDSA curve origins, using the model as a research partner on crypto history (Anthropic Research).

Why it matters

  • This is AI doing real STEM design work with a checkable artifact (circuit efficiency), not a vibe demo.

Four Argon agents clear Minecraft in 27 hours

AIpositive +0.8#agents#google#gemini-4-argon#deepmind#benchmarks

DeepMind's Gemini 4 Argon agents wrote 2,783 programs with no human help to beat Minecraft from scratch, while Argon also hits new research and game benches.

What they showed / shipped

  • Google DeepMind: four Gemini 4 Argon agents beat Minecraft from scratch in 27 hours, writing 2,783 programs, dividing jobs over chat, sharing notes, and debugging with no human help (x/@GoogleDeepMind).
  • Perplexity put Argon on WANDR (Wide-And-Deep-Research) as a new SoTA, live for Pro/Max in search and Computer (x/@AravSrinivas, x/@perplexity_ai).
  • Show HN: Gemini 4 Argon plays StarCraft (StarSkirmish).
  • 📌 On the radar: Sergey Brin says Google's models are reaching recursive self-improvement (Business Insider).

Why it matters

  • Multi-agent sandbox with only code + text is the artifact. Job split, shared notes, self-debug. That is the agent workflow people keep promising.

90% of US work hours sit outside AI benchmarks

AImixed +0.1#benchmarks#economics#data#mercor#public-perception

Mercor's labor-index map says most American working hours are spent on tasks current AI benchmarks barely cover, which reframes every leaderboard fight.

What they showed / shipped

  • Mercor Labor Index: 90% of US working hours are spent on tasks not covered well by AI benchmarks (Mercor).
  • a16z Charts of the Week: more than 1 in 3 Americans bought something based on an AI recommendation in the past year; 44% say AI helps them find better value (x/@a16z).
  • 📌 On the radar: 'It Ain't AGI Until H100s Go for $30 an Hour' argues compute price is the missing AGI tell (corbt).

Why it matters

  • If benchmarks miss 90% of real work, optimizing for SWE-bench-style scores is optimizing for a thin slice of the economy.

Astra Pro runs parallel agents inside ChatGPT

AIpositive +0.7#agents#openai#gpt-6-astra#model-release#tooling

OpenAI upgraded GPT-6 Astra Pro so multiple agents can split a task, run in parallel, and let you watch each one's progress in the Chat tab.

What they showed / shipped

  • OpenAI: GPT-6 Astra Pro in ChatGPT now has faster responses, better plugin/tool use, and multiple agents that tackle different parts of a task in parallel. Pro users can follow each agent's progress in the Chat tab (x/@OpenAI).
  • 📌 On the radar: Altman posted the Navier-Stokes milestone shirt with the last line of the solution chain-of-thought on the back (x/@sama).

Why it matters

  • Parallel agents with a visible progress UI is the product shape people have been waiting for inside the chat they already use.

Try today: reverse-engineer apps, open deciders, Elorian Glimpse

Techpositive +0.7#open-source#tooling#perplexity#elorian#ship-it

Perplexity wired a reverse-engineer skill into Computer with free credits, open-sourced new decision models, and Elorian Glimpse ships visual reasoning from the Gemini/MM-1 crowd.

What they showed / shipped

  • Perplexity integrated @morluto's Reverse-Engineer-Anything skill into Computer and is giving up to 10,000 bootstrapping credits to reverse engineer any app (x/@AravSrinivas).
  • Open-sourced pplx-decider-flash-v1.2 (4B, 1¢/M tokens, top 4B on HF Decision Index) and pplx-decider-v1.2 (27B, 2¢/M, #2 overall), weights on Hugging Face plus Decisions API (x/@AravSrinivas).
  • Elorian's Glimpse: first model from Gemini + Apple MM-1 researchers, built to reason with images (counting, visual puzzles, video), not just caption them (x/@minchoi, TechCrunch).
  • LocalLLaMA: ORL diffusion LLM claims 2,788 tok/s on one RTX 5090, fully open source (r/LocalLLaMA); ALoDLM 8B looped diffusion ~3x faster than Qwen3-8B base (r/LocalLLaMA).
  • 📌 On the radar: Stanford/Together/UIUC/Meta Hybrid Reasoning Agents paper (hidden internal thinking, text only when tools or final answer) (r/LocalLLaMA); Jev is Vercel's fastest-adopted AI model ever (TechCrunch).

Why it matters

  • Reverse-engineer credits + open decision weights + a visual-reasoning drop is a real Saturday lab session.

Runway adds Mirelo SFX 2.0, and video consistency jumps

Businesspositive +0.7#creator-economy#video-gen#voice#runway#mirelo

Runway now generates frame-synced soundscapes with Mirelo SFX 2.0 while keeping dialogue, and creators are showing seven-character swaps that hold environment and motion across 19 clips.

What they showed / shipped

  • Runway: Mirelo SFX 2.0 is live, automatic sound design synced to every frame, full soundscapes while keeping dialogue intact (x/@runwayml).
  • Venturetwins demo: a seven-character swap across 19 clips with environment and movement consistency that would have sounded impossible six months ago (x/@venturetwins).

Why it matters

  • Sound was the missing half of AI video. Frame-synced SFX without killing dialogue is a workflow unlock.

Postgres 19 delayed after AI finds more bugs than humans can fix

Techmixed +0.1#coding#tooling#postgres#claude-code#enterprise

AI code reviewers are surfacing so many real bugs that Postgres 19 slipped, which is the clearest 'AI review throughput > human fix capacity' receipt yet.

What they showed / shipped

  • The Register: Postgres 19 delayed after AI reviewers find more bugs than humans can fix (The Register).
  • Related process writeup: How the Claude Code team does code review (claude.dev).
  • 📌 On the radar: Accenture told employees they can spend only $29/month on Claude (r/singularity); Replit says it is no longer working with Anthropic (TechCrunch).

Why it matters

  • The bottleneck flipped. Finding bugs is cheap; fixing and verifying them is the scarce part.

Open infra lore: vLLM hit ~500k GPUs, Inferact raises $150M

Techpositive +0.6#open-source#infrastructure#vllm#a16z#economics

a16z retells how a two-week OPT speedup became vLLM on about 500,000 GPUs, and the core maintainers raised $150M for Inferact to staff it full-time.

What they showed / shipped

  • a16z: Woosuk Kwon's OPT-175B speedup project became vLLM with ~3,000 contributors, running on ~500,000 GPUs at a time; core maintainers founded Inferact and raised $150M (x/@a16z).
  • 📌 On the radar: China proposes export controls on 23 AI technologies including large models and agents, with already-open-sourced tech exempted (r/LocalLLaMA); Meta's new commercial terms may let it train on news sites without licensing fees (The Verge); Nvidia expands Mercedes driving partnership (x/@nvidia).

Why it matters

  • VLLM is the quiet layer under a huge share of local and cloud inference. The origin story is teachable and the hiring signal is real.
