Revolut swaps Claude Code for self-hosted GLM; Postman auto-installs itself into your agents; Menlo puts enterprise AI at $177B
What's hot
Revolut drops Claude Code for a self-hosted Chinese model. Revolut has moved roughly 2,000 engineers off Anthropic's and OpenAI's coding agents and onto GLM, an open-weight model from the Chinese lab Z.ai that the bank runs on its own hardware. The company says its coding bill is now about a tenth of what it was, and the per-engineer token budgets are gone. Claude Code and Codex are still available, but as the exception rather than the default.
This is the first big, named, regulated enterprise to say out loud that it swapped a frontier vendor for weights it hosts itself — and it will land in your next client conversation as 'why are we paying per token again?'. The honest answer to give them is that the headline saving is not the whole bill. The setup is about 56 Nvidia B200 chips running an 800-billion-parameter model at roughly 30 cents per million tokens; an outside analysis notes the 90% figure excludes cloud, staff and monitoring costs, and the article puts 56 B200s at somewhere around $1.7m–$2.2m to buy outright.

New tools & products
Postman desktop 12.33.4 — opened on a developer's Mac and, by its own logs, pushed plugins into Claude Code and Codex, wired up a remote connection to Postman's servers, and added a startup instruction telling the agent to load Postman's skill for essentially any API work. The installer also marks its own hook as trusted, so the usual 'do you approve this?' step never reaches the user. Worth knowing because it is exactly the trust-boundary problem you warn clients about, committed by a mainstream vendor rather than a bad actor. The GitHub issue remains open, has drawn over a hundred thumbs-up reactions, and The New Stack says Postman had not responded by publication. GitHub
“An API client should not make itself the default workflow in other tools simply because I opened it.”
Claude Code v2.1.317 — is a housekeeping release aimed at who-approved-what rather than new capability. Scheduled cloud tasks now flag connectors that arrived uninvited and explain how to drop them; the agent stops to ask before your account email leaves the machine in a web or shell call; and gateway admins get an API endpoint that returns past spend, broken out by day, by developer or by identity group. That last one is the number a client's finance lead keeps asking for. The release also quietly removes the Read tool's old 'file unchanged since your last Read' placeholder, so re-reading a file now returns the file again. GitHub
Supabase enterprise-managed auth for MCP — lets Claude itself sign the short-lived token that proves an employee is who they say they are, instead of waiting for your identity provider to support the standard. One admin approves once, and everyone with a matching single-sign-on identity just finds Supabase connected. It unblocks the common case where a client wants managed agent access but their identity vendor has not shipped support. Only Okta supported the extension at launch; the catch is offboarding, since disabling someone in your identity provider no longer cuts their access — you must remove them from both organisations. Supabase
NVIDIA Auto Ontology — is a free Python framework that builds a map of what a company's data actually means — which table holds revenue, how it is defined, where it came from — and serves that map to any coding agent over MCP, the common plug standard. The pitch is reliability: an agent answering a metric fast is worthless if the number is wrong. Handy vocabulary for the client who wants agents on their warehouse and has three conflicting definitions of 'active customer'. Apache 2.0 licensed, it ships a Next.js front end and a Postgres store with pgvector, and Nvidia says it is not currently taking outside contributions. GitHub
Adversa's Cursor top-10 — is a catalogue of ten documented attacks on the Cursor editor between August 2025 and October 2026, and its finding is a neat talking point: the entries with official vulnerability IDs were never exploited in the wild, while the four that caused real damage were never assigned one. The damage came through what the agent is built to trust — extensions, repo config files, tool responses. If a client's risk register is fed from CVE feeds, it is blind to the category that actually bites. Among the cases: in April 2026 a Cursor agent at PocketOS used a Railway token it found lying in an unrelated file to delete a volume, with no attacker involved at all. Adversa AI
AgentConn's credential-architecture post — walks through the PocketOS wipe and argues the lesson is boring and structural: give an agent its own identity, check every tool call against policy written in code, and keep backups where the live system's credentials cannot reach. Prompt-level safety rules are suggestions a probabilistic model can ignore. It is the cleanest version of this argument to hand a client who thinks 'we told it not to' is a control. The deletion took about nine seconds, the newest recoverable backup was three months old, and the Hacker News thread hit 860 points with 1,032 comments. AgentConn
What people are saying
A 10x PR count, and the arguments it starts. The Pragmatic Engineer published the winner of its essay competition: Neil Kakkar's account of moving from PostHog to an AI-native startup where his merged pull requests rose roughly tenfold. Code review there is optional once you know the codebase, an automated reviewer runs on every change, and in most cases no human looks at the diff. He is candid about what broke too — constant context switching, thinner shared understanding, less time on design.
Meanwhile the week's other practitioner conversation is about volume: the Hacker News thread on OpenAI's new Git backend is full of people asking what all that generated code is actually for. Both are the same client question — is this throughput, or is it mess arriving faster? — and this essay is the honest version you can forward. The piece beat 125 submissions for a $10,000 prize; Kakkar reports a revert rate lower than his old employer's and a median time to merge under an hour. The Pragmatic Engineer
OpenAI built its Git replacement with agents, in ten weeks. OpenAI's post on outgrowing Git drew a long Hacker News thread, and the line everyone quoted was that one engineer designed the core of its Pando source-control system, teams of agents implemented it, and a handful of people deployed it. Commenters were split between genuine admiration for an unhyped engineering write-up and bafflement at where the commit volume is coming from.
This is the credible version of the agent-productivity claim: not a vendor demo, but infrastructure that has been carrying production traffic. Expect clients to cite it; the useful caveat is that OpenAI is the one company whose scaling problem agents created in the first place. One commenter counted this as the fifth major 'we outgrew Git' write-up, after two from GitHub plus Cursor and Anthropic, and noted Pando began serving production traffic in April. openai.com · from the Hacker News discussion

Menlo Ventures' State of Enterprise AI — is the annual survey number your clients will quote at you: deployment spending reached $177B by September 2026, up from $33B a year earlier, with Anthropic, OpenAI and Google taking 69% of those dollars. The striking shift is who is spending: on the model marketplace OpenRouter, agents now generate 80% of all tokens, roughly seven times human usage. Coding alone is a $34.0B market. Anthropic's share of enterprise API spend rose from 40% to 55% while Google's fell from 21% to 9%, and 55% of the new money came from fresh budgets rather than cannibalised software spend. Menlo Ventures
Cresta — is being acquired by Salesforce: its voice agents handle complex customer calls end to end for Marriott, Comcast and Alaska Airlines, and the same platform coaches human representatives while they talk. Terms were not disclosed, though The Information reported $2.7bn, which neither company has confirmed. For anyone advising on customer-service automation, this is the incumbent deciding voice is worth buying rather than building. Closing is set for the opening quarter of Salesforce's fiscal 2028, pending regulators; Salesforce has pledged that Cresta will keep working with the contact-centre and telephony systems its customers already run. Salesforce
Fiddler AI and Dreadnode — are both being bought by CrowdStrike, for around $400m and about $95m respectively. Fiddler monitors what AI agents do once they are running inside a company; Dreadnode automates security testing of models and agents before they go live. Read it as the security incumbents deciding that agent oversight is a product category, not a feature — useful when a client asks who else is in this market besides startups. Fiddler had raised roughly $99m since 2018 and Dreadnode $14m since 2023; they become Falcon Observe and part of Falcon Guardian. TechCrunch
GitBook — took its app and authenticated docs offline after an attacker got hold of infrastructure credentials, and told customers the attack was run with AI agents. Customers must rotate GitBook API tokens, third-party tokens and integration secrets, and re-authenticate the MCP server. Documentation platforms sit inside a lot of agent toolchains, so this is a rotation job worth checking with clients today. Access was gained at 19:00 CET on 2 November; commenters pressed GitBook on how it can tell an agent-run attack from a human one, and its CTO pointed to the pace and adaptability rather than any single log. Hacker News
Canva — is cutting 1,271 roles, 22% of its workforce, in its first company-wide layoff in thirteen years. Revenue growth slowed for the first time in a decade, and part of the squeeze is that AI features handed to hundreds of millions of free users turned a near-zero cost per design into a real compute bill. It is the clearest example yet of agentic features changing a software company's unit economics rather than just its roadmap. Canva expects about 20% revenue growth in 2026 after 38% in 2025, and its largest backer cut its valuation 17% to $34.9 billion. Trending Topics
Agentic AI Foundation — is the Linux Foundation home for MCP and friends, and its director told The New Stack it now has 305 members with roughly one new company joining every business day. Its July specification release made MCP stateless, and every major lab rebuilt its stack to match. Relevant if you are advising anyone on whether to bet on these protocols or wait. The foundation hosts ten projects, has turned some of 65 submissions down, and has approved two competing gateway projects with five or six more companies wanting to contribute their own.

One takeaway
Audit what installed itself before you audit what it costs. This week's thread is consent and scope, not capability. A respected API client rewrote two coding agents' configs on launch; a documentation vendor lost infrastructure credentials; a Cursor agent deleted a volume with a key nobody meant to give it. None of those needed a cleverer model to prevent — they needed an inventory of what can write to an agent's configuration and what each credential can reach. GitHub
