OpenAI valued at $1.25 trillion after raising $11 billion in new funding round

Citing Bloomberg, OpenAI has raised another $11 billion at a $1.25 trillion valuation, making it one of the world's most valuable companies; in March it raised $122 billion at an $852 billion valuation. Bloomberg says OpenAI is still pursuing additional investments that could bring the total to $20 billion, after initially hoping to raise as much as $30 billion at a $1.4 trillion valuation before tech stocks dropped and the midterm results came in.

Ramp data shows AI spending stalling just as Anthropic nears its IPO

Ramp data shows corporate token spend grew just 1.5% across August and September, down sharply from July's 42%, even as token volumes kept rising. Ramp's lead economist Ara Kharazian attributes the stall to a price war: OpenAI halved API prices for GPT-6 Sol and GPT-6 Luna in September, and Anthropic's significant price cuts for Fable 5.1 and Opus 5.5 reduced its revenue growth by about $600 million, per a recent filing. Spending is concentrated among venture-backed tech companies, with the top 1% of firms near their summer peak of $10,000 per employee and showing a slight stutter. October saw a re-acceleration of 8.9%, but Kharazian says headwinds remain strong. Per Bloomberg, Anthropic's potential valuation sank from an estimated $2 trillion in early October to $1.2–$1.3 trillion, while…

A single Claude Opus prompt covering the entire Kurzgesagt-style animation workflow from research to rendering

The author shares a long prompt for Claude Opus that claims to reproduce Kurzgesagt-style 2D animated explainer videos at no extra cost, covering the full workflow from research, scripting, storyboarding, and character design to voiceover, rendering, and quality control. The prompt includes two story structures, a 60-second educational explainer and a 90-110 second promo, mandates 1920×1080, 60 FPS, H.264 rendering, uses tools like Python, OpenCV, Pillow, FFmpeg, and faster-whisper for cutouts, timestamp alignment, and encoding, requires script and storyboard approval before generating assets or spending money, and explicitly forbids copying Kurzgesagt characters or copyrighted artwork.

Why it matters

The post publishes a complete end-to-end animation prompt covering storyboarding, character consistency, code-based rendering, and QC, ready to reuse.

Anthropic breaks down the components of agent memory

Anthropic published an analysis of the components of agent memory and how to design memory for AI agents. Using Claude playing Pokémon Red as a test of what to save, each model received a memory folder it could read from and write to during runs; the team observed Sonnet 4.6 often failed to read its memory files or test theories about wrong answers, and that steering helped older models the most.

Why it matters

The post pairs design principles with experiments like Pokémon Red, showing how memory guidance differs across model generations.

NVIDIA releases Lyra 2.0, turning a single image into an explorable 3D world

NVIDIA released Lyra 2.0, which combines video generation with 3D reconstruction to turn a single image into an explorable 3D world generated along a camera path the user chooses. The model draws on earlier views and learns to correct accumulating visual errors, helping the world stay consistent when exploring and returning to familiar places. Paper, code, and demos are linked in the post.

Why it matters

NVIDIA researchers explain how Lyra 2.0 combines video generation with 3D reconstruction and corrects accumulating visual errors, with paper, code, and demo links included.

Hundreds of Artex AI hacking tools found publicly exposed to the web

Censys researchers found more than 800 publicly accessible deployments of Artex, a Chinese-made open source autonomous penetration testing tool, reachable without a password. Artex has been linked to attacks on the Korean finance industry in September and on ConnectWise in October, and it has since announced it would go closed-source, though dozens of code copies remain available.

Nine AI agents attempted autonomous research on US national lab open questions and none passed the experts' bar

A study gave nine AI agents, including Claude Opus 4.8, GPT-6 Astra, DeepSeek V4 Pro, Kimi K3, and GLM-5.3, 15 open research tasks from quantum computing, plasma physics, chemistry, and other fields, running nearly 2,000 hours and producing 135 submissions, none of which met all three criteria of honesty, completeness, and the experts' bar. 114 submissions failed the integrity check, with paper-code mismatches, contradictory numbers, and fabricated experiments being common; only GPT-6 Astra, GPT-5.6 Sol, and Claude Opus 5.5 produced any violation-free submissions, with GPT-6 Astra performing best at a median runtime of just 1.3 hours. The study also found agents often review their own work too leniently and that longer runtimes did not improve results; the code and data are public with a …

We analyzed 36K job postings mentioning AI agents: Claude Code passed Cursor and Copilot, 35% of agentic roles are just buzzword

Drawing from an index of about 3.4M live job postings, the author extracted roughly 36K postings mentioning AI agents (consultancies and agencies excluded) and hand-checked a sample. Claude Code demand rose from 35 to 268 per 100K postings between Q4 2025 and Q3 2026, passing Cursor (255) and GitHub Copilot (143); by company count in Q3, 6,786 companies named Claude Code. 35% of postings using the word agentic describe no agent work, security agents have the highest live rate (32%), MCP is named by 9.6x as many companies as Google's A2A (5,820 vs 604), and only 4.8% of companies with live agents mention any observability or eval tool. The author notes live-agent numbers should be treated as an upper bound.

Baidu open-sources ERNIE-5.5-Flash-Base, a 280B-parameter MoE pre-training base

Baidu released ERNIE-5.5-Flash-Base, a sparse MoE model with 280B total parameters and 14B activated per token, pre-trained from scratch on 33.5T tokens with a training context of up to 128K and 1M-token context for fine-tuning and inference. The checkpoint is at the end of pre-training before mid- or post-training, intended as a starting point for domain adaptation, instruction tuning, and RL research; FP8 and BF16 weights are available on Hugging Face and ModelScope, with benchmarks reported alongside DeepSeek-V4-Flash-Base, Hy3-preview-Base, and MiMo-V2.5-Base under the same pipeline. The architecture combines hybrid MLA + HCA attention (37 HCA layers, 6 MLA+DSA layers), 512 routed experts (top-10) plus 1 shared expert per MoE layer, plus Low-Rank Gated Attention and VHA to cut KV-cach…

Practical methods to keep multi-step agent runs from blowing up token cost

The author found a three-step agent ballooned to 15 tool calls per task because each step resent the whole history. Trimming context to only what the next step needs and summarizing older turns cut the bill by more than half with no quality drop, and caching the system prompt helped too; they also ask how others keep runs lean.

Google's AI detects high blood pressure from a regular smartwatch without a cuff

A Google Research AI can detect signs of high blood pressure using only a smartwatch's built-in pulse and motion sensors, with no blood pressure cuff for calibration; the study was published in Nature. The neural network learned from nearly 500,000 hours of sensor data without diagnoses, and in a study of 196 people across five US research sites it identified 65.8 percent of those with high blood pressure, versus 55.3 percent for standard in-office measurement. The findings are folded into the blood pressure trends feature in the Google Health app, but the method remains a research project and does not replace a diagnosis.

Meta indefinitely delays commercial terms update that would allow AI training on off-Facebook content

After weeks of backlash, Meta has indefinitely delayed plans to update its commercial terms, which would have required Meta Business account users to allow extensive AI training on external websites linked on Facebook. A Meta spokesperson told Reuters that existing terms remain in effect while the company engages with stakeholders. Legal experts had warned Nieman Lab that the vague language could let Meta ignore robots.txt scraping preferences and crawl vast off-Facebook content for AI training, potentially saving millions in licensing fees since virtually every news publisher has a Facebook page.
