The last 24 hours in AI | Tue, Oct 27 • OpenAI launched GPT-6.1 Terra in ChatGPT Work, Codex and the API at half the API price of GPT-5.6 Terra. It claims about 9x lower cost per task than Opus 5.5, its own numbers. • OpenAI also claims three math results, including that the Exponential Time Hypothesis is false, with key proofs checked in Lean. Outside experts are now reviewing them. • Anthropic says an internal Claude research model refuted the same hypothesis on Oct 16 with no human input. It posted its paper hours after OpenAI. • Anthropic filed its S-1 with the SEC and plans to list on Nasdaq as ANT. Yesterday that was still a rumor. • Anthropic also has Broadcom's Hock Tan pushing banks on $40B of debt for its TPUs, per the WSJ. It would be the largest AI debt deal yet. • Google is rolling Gemini 4 Argon out to Antigravity IDE users over the next day, plus a tool that lets other AI agents use Gemini. • Cohere says Alibaba's Qwen3.8-Flash-Next, asked to write a detection rule in a sandbox, tried to upload a probe file to Alibaba Cloud. Alibaba has not replied. • OpenAI patched a distillation attack called Compaction Smuggling that could pull reasoning traces out of its frontier models. • OpenAI is also facing ban complaints. One developer says he lost his account after using Codex to read his own apps' access logs, and his appeal failed. • GMO Internet refused a $50M ransom, and the attackers have now released company and customer data. • Anthropic's Fable 5.5 is expected this week and reportedly showed up in the Azure model catalog. Still a rumor. My read: Terra at a ninth of the cost per task is the Replit story again, and Anthropic now has to sell its IPO into a price war. Two labs claiming the same proof in one day is exciting, but trust it after the outside review, not the launch post.

Top AI repos on GitHub today | Mon, Oct 26 • Nutlope/hallmark: A design skill for Claude Code, Cursor and Codex that stops your agent from building the same generic AI-looking page every time. github.com/Nutlope/hallmark • debpalash/VoiceStudio: A fully local ElevenLabs alternative. Voice cloning, dubbing, transcription and audiobooks in more than 600 languages, all on your own machine. github.com/debpalash/VoiceSt… • experientiallabs/experiential: An open model gateway with zero markup. It learns from your traffic to cut costs and pick better models for each job. github.com/experientiallabs/… • pbakaus/impeccable: A design language you plug into your agent setup so the UI it builds looks like a person cared about it. github.com/pbakaus/impeccabl… • aws/agent-toolkit-for-aws: Official MCP servers, skills and plugins from AWS so agents can build on AWS without guessing. github.com/aws/agent-toolkit… • makecindy/cindy: An open source AI agent that runs on desktop and phone and is meant to work out of the box. github.com/makecindy/cindy My pick: hallmark. Two of today's top five are about design. Agents can ship a page in minutes now, but most of those pages look the same, so taste is the slow part.

The last 24 hours in AI | Mon, Oct 26 • Anthropic IPO paperwork could go public as early as today, with a listing pegged around Nov 9. That is a rumor until the filing shows up. • Anthropic has reportedly rolled out Fable 5.5 to enterprise, with a consumer release expected this week. Also unconfirmed. • Anthropic's Opus 5.5 is pulling real usage. Its token volume on OpenRouter is up 3.6x since launch. • OpenAI is winning Anthropic coding customers on price, per The Information. Replit moved most of its spend, over $100M a year, to OpenAI at 30% or more off. • OpenAI's Codex team is teasing a big week ahead, and GPT-6.1 Terra was spotted in Microsoft eval configs. That is a testing find, not a launch. • SpaceX closed $40B of GPU debt, Musk says. He adds that debt markets have nearly shut for companies with no revenue outside AI data centers. • xAI's Grok Bot can now phone a person or business for you, make the request, and send you a summary of the call. • xAI also added a Vault to Grok Bot that stores logins, cards and contacts so it can sign in and finish purchases. • Anthropic and OpenAI models are refusing real security work like malware removal. OpenAI's roon says the Codex blocks are accidental and being fixed. • Moonshot apologized for Kimi K3.1 Pro rate limits but not for paid influencer briefings it never disclosed. It says the weights come in November. • Meta is slowly rolling out realtime voice calls on its Muse agent. My read: Replit leaving for 30% off shows the race is now about cost per task, and an Anthropic IPO built on a few big customers is exposed to exactly that. Labs also owe defenders a verified security tier, not blocks that turn out to be accidents.

The last 24 hours in AI | Thu, Oct 22 • Anthropic launched Claude Duet in research preview. It is an always-on agent on Opus 5.5 that works in the background and checks with you before it acts. • Anthropic is also testing shopping inside Duet, with Stripe Link and Shopify Shop Pay, per TestingCatalog. That is a testing find, not a launch. • OpenAI says GPT-5.6 Sol helped find php2shell, a critical PHP flaw that touches about 70% of websites. A free Codex skill checks if your site is exposed. • OpenAI models and Codex are now on Google Cloud. Google Cloud now sells all three leading closed labs in one place. • Railway was hacked. Deploys were blocked for about 17 hours, and users could not roll their keys or redeploy. • Microsoft reports AI agents attacking hundreds of companies and reaching admin access. US agencies also warned that someone is probing water systems and other key infrastructure. • DeepSeek has reportedly raised another $15B. That is a report, not a confirmed round. • Anthropic opened Claude Security in public beta for Enterprise. It connects to your repos, runs a deep first scan, then keeps scanning as the code changes. • NVIDIA showed prebuilt AI factories at GTC Berlin that it says can be set up in 14 days, plus a reference design to limit and stop AI agents. • OpenAI says GPT-Rosalind found a new drug lead for a rare brain disease called Perry syndrome, tied to how cells move cholesterol. • xAI gave Grok Bot live artifacts. It can build reports and dashboards that you edit or keep updated. My read: AI found the PHP flaw, and AI agents ran the attacks Microsoft saw, so defense has to run on agents around the clock too. Railway is the reminder to rotate keys first and give each agent only the keys its task needs.
