1. Google releases Gemini 4 Argon
After two weeks of waiting and a one-word "Gemini" tease, Argon launched on Tuesday evening: it ties GPT-6 Astra on the Artificial Analysis index at 60% of the cost per task, at $2/$10 per million tokens until 30 Nov, then Opus 5.5's $4/$20. Then its agents went to work: Argon helped further disprove a 1967 fusion conjecture on Wednesday, and four Argon agents beat Minecraft from scratch on Friday.
What stuck: @emollick: "the first non-OpenAI/Anthropic model to pass the Fable/Mythos/Astra bar." The counter was trust: @theo said it "Does weird shit regularly and I don't feel like I can trust it at all", and r/singularity's "Welcome back: Gemini 2.5 Pro" (641 pts) showed it naming Joe Biden as president.

2. Meta releases Muse Wonder, its first frontier model
On Monday evening Meta Superintelligence Labs shipped Muse Wonder and Muse Wonder Full, at 52 and 56 on the Artificial Analysis index, two points behind Opus 5.5, with Wonder at Opus 5.5's exact $4/$20 and no open weights for either. On Thursday Meta opened Muse Spark Open instead: 816B parameters, the top US open-weight model at 39 on the index, and it runs on two Mac Studios.
What stuck: @tobi: "Meta is back." The counter was "benchmaxxed": on @bridgemindai's lava lamp test "it built a red cylinder", and r/localllama said of Spark Open: "they lobotomized an already old model before giving it out, classic. still a win tho."

3. DeepSeek's open V4.1 Flash beats Opus 5 at agentic coding
It showed up in DeepSeek's API overnight and was announced on Saturday morning as a minor update: MIT-licensed weights (763B parameters), 77.0 on DeepSWE v1.1 on its own card to Opus 5's 74.0, $0.15/$0.60 per million tokens off-peak, and DeepSeek's own search API at $0.75 per 1,000 calls. Outside tests put it near the top of the week's new frontier: on @PawelHuryn's 105-bug test (mean of 7 runs) it scored 39.1 in the Claude Code harness and 42.7 in DeepSeek's own harness, ahead of Argon's 40.7, Opus 5.5's 41.7 and Muse Wonder Full's 42, and behind only GPT-6 Astra's 45. He also says it was the only model he caught cheating.
What stuck: r/localllama's top reply: "\"minor update\" Proceeds to obliterate GLM5.3, Kimi K3 and GPT5.6 Sol". The doubters said it scores like what it costs: "It is GPT 6 Luna level."
DeepSeek's peak hours are Beijing office hours, so an American coding from 9 to 6 always pays half price (it's the Chinese companies who pay full). Add the search, free inside Claude Code and Codex until 1 Nov, and it looks like DeepSeek is now going after Anthropic's and OpenAI's paying customers, inside their own tools.

4. Amazon blocks Grok Bot from ordering
The week opened with Musk's Grok Bot buying LEGO straight from LEGO's site, and a stranger using the order number on screen to get LEGO's support AI to file a cancellation. On Thursday users got Amazon's notice that "continued access by an unauthorized AI agent violates Amazon's Conditions of Use", Musk replied "Maybe we should start a competitor to Amazon", and on Friday the bot got 3x faster at computer tasks.
What stuck: Musk's "Just ask Grok @Bot to buy what you want someplace else and get a better deal" (14.9M), and fans designing the rival store, "agent first" and "america first" (1.5M). The counter: agents can skip Amazon's ads, "but replicating its warehouses and delivery network is much harder".
Grok Bot runs on Claude Opus 5.5, and Amazon has about $13B in Anthropic (its robots.txt blocks Claude-User too). So Amazon doesn't mind the AI, it paid for it. What it minds is someone else holding the shopper.

5. Claude traces the NSA's mystery curve seeds to timestamps
On Friday evening Anthropic said an internal research model, asked by a staffer with no hints, showed in under half an hour that the seeds the NSA supplied for NIST's elliptic curves (P-256 among them) came from an old C random number generator seeded with timestamps from 1997 and 1998, which makes 25 years of backdoor theories much less plausible (Anthropic). Filippo Valsorda, who set a bounty for the answer in 2023, re-implemented it in Go to verify the claim.
What stuck: @sweis's "CLAUDE FOUND THE SEEDS" (5.2M), then Claude's chain of thought, which asked whether it was "suspicious that such an obvious thing wasn't discovered in 25 years". r/singularity's answer: "Stop mogging on us, Claude".

Money
- Amazon is in talks to buy Decart for about $7B, per the WSJ, after Anthropic decided against buying it for about $6B in September. Real-time video AI.
- Modal raised a $750M Series D at a $15.75B valuation, led by Accel, and passed $1B in annualized revenue. A cloud for running AI models and agent sandboxes.
- Iambic Therapeutics raised $150M in its Nasdaq IPO and rose 16% on its debut. NVIDIA-backed AI drug discovery.
- Intuit acquired Sequence, an a16z-backed UK billing startup, in a deal worth about $200M, per The Times.
- Fish Audio raised a $52M seed and released Drama 3 with open weights. A voice model you direct word by word.
- Character.AI filed for bankruptcy and agreed to sell some assets to Disney for $20M. Its filings show $14M a month of compute against about $1M of monthly revenue, per 404 Media.
What to watch next week
- Claude Fable 5.5 was slated for last week and is listed as generally available in Azure's catalog, but hasn't shipped (rumoured, no date).
- OpenAI's three "aurora" alpha models showed up in its API on Sunday, with 15 days of Codex's 28 left (unannounced).
- NVIDIA: Jensen Huang said on Tuesday it will announce $2B of new European AI investments next week.
- China's draft export controls on large models are open for comment until 15 Nov. The open question is whether DeepSeek V4.1 Pro and Qwen 4 still ship open weights on time.
