AI Daily Brief — 1 May 2025

May Day mega-cycle. Anthropic shipped Integrations with MCP servers and a 45-minute Research mode. OpenAI completed the GPT-4o sycophancy rollback and turned ChatGPT shopping search on globally — 1B+ web searches the prior week. Apple’s Q2 call carried Cook’s first public tariff number. And a covert U. Zurich AI persuasion experiment on r/changemyview broke open.

Top stories

  • Anthropic launches Claude Integrations and advanced 45-minute Research mode. Integrations framework connects Claude to remote MCP servers across web and desktop apps. Launch partners: Atlassian (Jira/Confluence), Asana, Zapier, Cloudflare, Intercom, Square, Sentry, PayPal, Linear and Plaid (with Stripe, GitLab and Box to follow). Research mode autonomously plans and executes multi-step investigations across the web, Google Workspace and integrations for up to 45 minutes per query, producing cited reports. Beta on Max, Team, Enterprise; web search globally available to all paid Claude users. via Anthropic
  • OpenAI fully rolls back the GPT-4o sycophancy update. Free users reverted first; paid users later in the day. OpenAI signaled future personality-selection options (‘eventually we clearly need to be able to offer multiple options’). via VentureBeat
  • ChatGPT shopping search rolls out worldwide to Pro, Plus, Free and logged-out users. Visual product details, pricing, reviews, merchant lists and direct buy links. Results independent of paid ads. OpenAI disclosed ChatGPT had handled more than 1 billion web searches the prior week — escalating its direct challenge to Google for product discovery. via OpenAI
  • Apple Q2 FY25: $95.4B revenue, EPS $1.65; Cook flags ~$900M tariff hit. Revenue +5% YoY, EPS +8%, double-digit Services growth. On the call Cook publicly addressed Trump-era tariffs for the first time, estimating about $900M in added costs in the June quarter and outlining supply-chain reshuffles (more US-bound iPhone production to India). via Apple
  • Microsoft AI capex commentary: AI run-rate $13B+ growing 175% YoY. CFO Amy Hood: Q4 FY25 capex steps up sequentially to support AI scaling, but FY26 capex growth will be slower and shift toward shorter-lived assets (GPUs/CPUs) more directly tied to monetization vs long-lived datacenter shells. Microsoft noted dock-to-live for new GPU capacity cut ~20% and AI perf-per-ISO-power improved ~30%. Cost-per-token more than halved.
  • U. Zurich’s unauthorized AI persuasion experiment on r/changemyview surfaces. Researchers ran a four-month covert experiment on Reddit’s r/changemyview (3.8M members), posting 1,700+ AI-generated comments under fabricated personas (rape victim, Black man opposing BLM, trauma counselor). Study claimed AI comments were ~6x more persuasive than human responses. Reddit CLO Ben Lee called it ‘improper and highly unethical’; Reddit prepared formal legal demands and the researchers agreed not to publish. The university opened an internal investigation. via Science

Who shipped

Anthropic ran the most concrete product day with Integrations + 45-min Research. OpenAI ran the user-facing day with the rollback and shopping search. Microsoft and Apple set the macro tone via earnings.

Open-source pulse

Anthropic’s MCP-based Integrations effectively extends the MCP protocol it pioneered into a broad partner network. No major model open-weights drops dated May 1 — community still benchmarking Qwen3 and DeepSeek-Prover-V2 from the prior days.

Money, infra & hardware

Microsoft’s $13B+ AI run-rate (+175% YoY) is the largest concrete AI-revenue disclosure to date from any hyperscaler. Apple’s $900M tariff disclosure is the first hard number from a Mag-7 CEO on Trump-era tariff impact.

Quiet corners

Google DeepMind, Meta, xAI quiet on the model side.
