Try Jotform for freeToday, we've got Google's Gemini 4 Argon going fully public and undercutting its rivals on price, Claude quietly solving a cryptography puzzle the NSA left unsolved for 25 years, Anthropic handing 5% of itself to a public benefit fund, and Disney picking up most of Character.AI's team.
On this day in 2017…
Nature published DeepMind's AlphaGo Zero paper, "Mastering the game of Go without human knowledge." No human game records, no opening book — just the rules and self-play. It reached superhuman strength in days and beat the version that had defeated Lee Sedol 100 games to nothing. Nine years later, we're still arguing about how much human data a model actually needs.
🚀 Gemini 4 Argon Goes Public — and Undercuts Everyone
After two weeks of limited access for security partners and the US government, Google opened Argon to AI Pro and Ultra subscribers on October 13. DeepMind says it took sole first place in 13 of 19 evaluation categories, including 51.3% on AutomationBench against GPT-6 Astra's 41.4% and Claude Opus 5.5's 42.5%. The sharper number is the price: $2 per million input tokens and $10 output, versus $4/$20 for Opus 5.5 and $10/$50 for Astra. The frontier just got cheaper to rent.
🔐 Claude Closes a 25-Year NSA Cold Case in Under 30 Minutes
The seed values behind NIST's standard elliptic curves have been a cryptography conspiracy theory since 2000 — the NSA supplied them and never explained where they came from, which left the door open to a deliberate backdoor. Claude figured out they were generated by lrand48, a plain C random number generator, and did it in half an hour. Backdoor theory: substantially weakened. Hacker News: 1,048 points and 387 comments of disbelief.
🏛️ Anthropic Pledges 5% of Itself to a Public Benefit Fund
Ahead of a reported IPO, Anthropic says it will commit 5% of its shares to a public benefit fund. For a company that just posted $16.8B in Q3 revenue, that is a large number attached to a governance promise — and it lands the same week Anthropic is also pushing a federal AI safety bill and consulting law firms on how negotiating agents should behave.
🎭 Disney Agrees to Hire Most of Character.AI's Workforce
Five years after launch, the chatbot platform that defined AI companionship filed for bankruptcy — and Disney has agreed to take the majority of its staff, with the "vast majority" of those offered jobs accepting. It's a stalking horse bid, so a higher offer could still appear. Either way: consumer AI companions turned out to be a feature, not a company.
⚡ perplexityai/SPACE is the Firecracker-based sandbox Perplexity has used to contain every Perplexity Computer agent session since July, now open-sourced under Apache 2.0. Each task gets its own microVM, credentials live outside the box, and the host controls egress. Perplexity red-teamed it with nine frontier models across 216 runs: zero escapes to the host, including runs where the model was handed SPACE's own source code. Written in Rust, driven over an HTTP API, with CoreWeave, Akamai and Crusoe lined up to offer it.
🪞 reflection-oss/mirror is Reflection's coding harness — a terminal coding agent in Rust and Python, Apache 2.0 — and it pairs with the big release of the week: Beam's weights landed on Hugging Face on October 16. That's 501.3B total parameters, 23.4B active, a one-million-token context window, BF16/FP8/NVFP4 builds, a speculative-decoding drafter, and fine-tuning plus RL recipes for NeMo RL, TRL, SkyRL and Axolotl. All of it Apache 2.0.

🇬🇧 The UK gets its pre-release model access back
After September's White House request that labs stop sharing new models with the UK's AI Security Institute, the decision has reportedly been reversed. AISI scientists are evaluating the current generation again, Argon included.
⚖️ Anthropic's safety bill has a very high floor
The proposal only triggers at 50 deaths or $1B in damages, and would effectively make the Commerce Department the only agency able to stop a model. Reaction on Hacker News was not warm.
👔 Anthropic has nearly stopped hiring junior staff
Junior roles fell from 27% to 9% of new technical hires since early 2025, while by August 2026 the company's AI agents were logging six times as many hours as its humans. Researchers call the risk a "tragedy of the cognitive commons": no juniors now, no seniors later.
