WEEK OF NOV 1 – 7, 2025

Frontier weights for free, compute at $38B: the week the open-model cost floor met the capex bill

A trillion-parameter open-weight agent and a 12-hour autonomous scientist shipped in the same seven days that OpenAI committed $38B to AWS and a UK judge set the first boundary on AI copyright.

The window ran Monday to Thursday hard. On Nov 3 OpenAI signed a $38B, seven-year AWS deal, its first contract with the cloud market leader and the formal end of Microsoft's cloud exclusivity; on Nov 5 Edison Scientific announced Kosmos, an AI scientist whose single run reads 1,500 papers and writes 42,000 lines of analysis code; on Nov 6 Moonshot AI published Kimi K2 Thinking weights and Google Cloud opened Ironwood, its inference-first TPU, to customers.

Two of those stories are the same story told twice. Kimi K2 Thinking activates 32B of its 1T parameters per token, ships under a modified MIT license with a 256K context window and native INT4, and was reported by CNBC — from an unnamed source — to have cost $4.6M to train, three days after the most valuable private AI lab in the US committed $38B to rent other people's GPUs. Open weights are the price ceiling on closed APIs now, not the consolation prize.

The market read the week differently. Michael Burry's 13F, filed Nov 3 and reported Nov 4, disclosed puts on Nvidia (about $187M notional) and Palantir (about $912M); the Nasdaq fell 1.9% on Nov 6, and Palantir ended the week down more than 12%. Builders got a cheaper stack and a repriced one in the same five days.

Moonshot publishes Kimi K2 Thinking: 1T parameters, 32B active, modified MIT, native INT4

Moonshot AI released Kimi K2 Thinking on Nov 6 with weights on Hugging Face: a mixture-of-experts model of 1T total parameters activating 32B per token, 384 routed experts with 8 selected plus one shared expert, 61 layers, MLA attention and a 256K context window. It is a native INT4 checkpoint — quantization-aware training applied to the MoE components in post-training — for roughly 2x generation speed and a smaller disk and VRAM footprint, and it runs on vLLM, SGLang and KTransformers behind an OpenAI and Anthropic-compatible API. The license is modified MIT: unrestricted commercial use except that products above 100M monthly active users or $20M monthly revenue must display Kimi K2 in the UI.

The self-reported numbers put an open download next to closed frontier models: 44.9% on Humanity's Last Exam with tools against GPT-5's 41.7%, 60.2% on BrowseComp against 54.9%, and 71.3% on SWE-bench Verified, with Moonshot claiming stable tool use across 200-300 sequential calls where earlier models drift after 30-50. CNBC reported the training bill at $4.6M from a source familiar with the matter, which it could not independently verify; Moonshot's CEO later said on Reddit that the figure is not official.

WHY IT MATTERS

Long-horizon agent traces are the expensive part of your bill — hundreds of tool calls, each carrying a growing context — and this is the first openly downloadable model sized for exactly that workload, with INT4 weights so the memory maths is survivable on hardware you own. The practical effect: you can put a frontier-adjacent agent loop behind an OpenAI-compatible endpoint, self-host or buy at open-model prices, and treat closed-API token pricing as a comparison rather than a constraint. The license clause bites only at hyperscale, so white-label use below 100M MAU is unaffected.

Google Cloud opens Ironwood (TPU v7) — 10x v5p peak, 9,216 chips per superpod

Google Cloud announced Ironwood, its seventh-generation TPU, for Cloud TPU customers on Nov 6, pitched at what the post calls the age of inference: 10x peak performance over TPU v5p and more than 4x per-chip performance versus TPU v6e for both training and inference, 9,216 chips in a single superpod over 9.6 Tb/s inter-chip interconnect sharing 1.77 PB of HBM. Anthropic, which said in October it plans to access up to 1 million TPUs, is the flagship customer.

The developer-facing change is the software layer: enhanced vLLM support on TPU behind a unified backend, so a serving stack can move between GPUs and TPUs with minor configuration changes, plus a GKE Inference Gateway that Google says cuts time-to-first-token by up to 96% and serving cost by up to 30% by load balancing across TPU servers. CNBC reported the same day that Google Cloud VP Amin Vahdat told an all-hands the company must double AI serving capacity every six months.

WHY IT MATTERS

Inference, not training, is what a software team actually pays for, and the accelerator market just became less binary: if the same vLLM server runs on TPU, capacity sourcing is a deployment config rather than a rewrite, and you gain a second quote to hold against GPU pricing. Combined with the same week's open-weight releases, agent workloads get a cheaper denominator on both sides — model and silicon — which is the number that decides whether a long-horizon agent feature is viable at your volume.

Kosmos: one 12-hour agent run, about 6 months of research — the world model is the trick

Edison Scientific, the commercial spinout of non-profit FutureHouse that took over its platform the same day, announced Kosmos on Nov 5. Kosmos runs for up to 12 hours on an open-ended objective and a dataset, executing about 200 agent rollouts that collectively write roughly 42,000 lines of analysis code and read about 1,500 papers per run. The architectural claim is that a structured world model, shared between a data-analysis agent and a literature-search agent, is what keeps a single objective coherent across tens of millions of tokens — the failure mode that capped earlier AI scientists at a handful of coherent steps.

In the technical report, independent scientists rated 79.4% of statements in Kosmos reports accurate, and every conclusion is traceable to specific lines of code or passages of literature. In a poll of seven beta users, a 20-cycle run was estimated at 6.14 months of their own research time, and estimated human-equivalent duration scaled linearly with run depth. It is available at $200 per run, with caveats the authors state plainly: Kosmos goes down rabbit holes and chases statistically significant but scientifically irrelevant findings.

WHY IT MATTERS

The transferable piece is the harness, not the science: a persistent external state that survives context exhaustion is the pattern any long-horizon agent needs, and code-level provenance for every claim is the difference between an agent you can audit and one you cannot. It also puts a concrete number on inference-time scaling for open-ended work, which is what you budget when deciding how much compute a task deserves.

UK High Court: Stable Diffusion is not an infringing copy — Getty's secondary claim fails

Mrs Justice Joanna Smith handed down Getty Images v Stability AI on Nov 4. Getty's remaining secondary copyright infringement claim failed: the court accepted that a model can be an article under the Copyright, Designs and Patents Act, but held that Stable Diffusion is not an infringing copy because it does not store or contain the training images — once the weights stop holding a copy, they stop being one. Getty had already abandoned its primary copyright and database-right claims during trial because training happened outside the UK; it won only narrowly on trade mark, over generated images carrying its watermark.

Litigation volume continued in the same seven days: Danish collecting society Koda sued Suno in Copenhagen City Court on Nov 4, author Tasha Alexander filed a class action against Salesforce over its CodeGen and XGen models on Nov 5, and Entrepreneur Media sued Meta over Llama on Nov 6, taking US AI copyright filings past 60. The ruling follows the US arc of Judge Alsup's June 2025 decision that Anthropic's training was fair use but its retention of pirated books was not, and the resulting $1.5B settlement filed on Sept 5.

WHY IT MATTERS

Shipping weights looks materially safer in the UK now — distributing a model is not itself infringement — but the load-bearing test is the useful part: liability turned on whether the pipeline ever held a copy, which is exactly what cost Anthropic $1.5B for keeping a library it did not need. Dataset handling, retention and provenance logging are now the primary legal control surface rather than training itself, so vendor questions become about where data is stored, for how long, and how deletion is proved. Expect an appeal.

OpenAI commits $38B to AWS — days before a $4.6M open-weight model matches frontier scores

OpenAI and AWS announced a multi-year partnership on Nov 3: a $38B commitment over seven years, hundreds of thousands of Nvidia GB200 and GB300 GPUs on Amazon EC2 UltraServers, the ability to scale to tens of millions of CPUs for agentic workloads, and all target capacity deployed before the end of 2026. It is OpenAI's first contract with the largest cloud provider and the clearest break from the Microsoft-exclusive era; Amazon closed at a record, up 4%.

It is the fourth commitment in a run — roughly 10 GW with Nvidia, 6 GW with AMD, 10 GW of Broadcom custom accelerators and a reported Oracle deal — leaving OpenAI with close to $600B of cloud commitments against about $13B of expected 2025 revenue. The market started repricing that assumption two days later: Michael Burry's 13F disclosed puts on Nvidia and Palantir, and the Nasdaq fell 1.9% on Nov 6 with Palantir down more than 12% for the week.

WHY IT MATTERS

Two of the things you architect around moved this week: where inference capacity physically lives, and what it costs. Note that OpenAI is buying CPUs at agentic scale as well as GPUs — that is a statement that the volume driver is multi-step tool loops, not chat, which is what most teams now build against. Because that capacity is sold forward on multi-year commitments, closed-API pricing is exposed to a financing model that assumes continued exponential growth, so an open-weight fallback with compatible APIs is a procurement hedge rather than a purity test.
