Notion is shutting down Notion Mail on September 22, citing that over half its users already manage email entirely through AI agents. Anthropic's Claude saw ~75% paying consumer revenue growth since January and now leads ChatGPT in DataCamp course searches 3-to-1. JetBrains selected OpenAI's Codex as the default recommended agent in its IDEs after benchmarking across Java, C#, and Python tasks. Additional items cover Patronus AI's $50M raise for agent stress-testing, Sail Research's $80M round, Vercel's AI SDK 7 release, MCP spec security risks flagged by Akamai, and GitHub Copilot code review cost reductions. ## Content **TLDR:** The Trump administration asked OpenAI to restrict GPT-5.6 to a select group of partners during a safety review period, mirroring what Anthropic is already doing voluntarily with Claude Mythos. Notion is killing Notion Mail on September 22 after discovering over half its users already manage email entirely through AI agents. Anthropic's Claude grew paying consumer revenue roughly 75% since January, with Claude now the top search term on DataCamp — outpacing ChatGPT course demand 3-to-1. JetBrains selected Codex as the default recommended agent in its IDEs after a structured benchmark across Java, C#, and Python tasks. --- ## White House asks OpenAI to gate GPT-5.6 behind partner approvals over safety concerns The Trump administration told OpenAI to limit GPT-5.6 access to a vetted set of partners rather than releasing it publicly, with Sam Altman telling staff that government approval would happen customer by customer during a preview window. The concern is that frontier models capable of finding and exploiting software vulnerabilities at machine speed could be weaponized. This mirrors Anthropic's voluntary Project Glasswing approach with Claude Mythos, which is already restricted to a small partner set. Separately, speculation circulating suggests GPT-5.6 may be less token-efficient than 5.5 with no price reduction — which would make it a tough sell given open-source competition from models like GLM 5.2.

The company is pivoting entirely toward its agent developer platform, which has seen over one million agents built by customers. Users connected via Gmail keep their email; drafts and scheduled emails need manual export before the deadline. It's a concrete data point that agent-native workflows are replacing human-facing UIs faster than most product teams anticipated.

DataCamp, with 20 million users, reports Claude is now its most searched term — with Claude course demand outpacing ChatGPT 3-to-1 among self-directed learners. ChatGPT still leads on total users, crossing 1 billion monthly users in May, but its market share dipped below 50% for the first time in March. Both companies are approaching IPO, with Anthropic filing confidentially at a valuation near $965 billion.

Codex (GPT-5.4 mini with medium reasoning) and Junie (Gemini 3 Flash) were close in offline benchmarks, but an online A/B test with real users tipped the decision to Codex based on activation, churn, and failure rate signals. Users can still switch to Junie, Claude Agent, or any ACP-compatible agent at any time. The recommendation will be revisited as models and benchmarks evolve.
