Replit drops Anthropic for OpenAI partnership
At TechCrunch Disrupt 2026, Replit CEO Amjad Masad announced that OpenAI is replacing Anthropic as the default AI model provider for its platform, citing cost, partnership, and superior performance, especially on internal benchmarks for vibe-coded applications. However, Anthropic's Claude models remain available for customers, and a source familiar with the matter claimed the Anthropic partnership is still active, with Replit's website and social media showing recent use of Claude models. Replit's enterprise revenue grew from 2% to 15% of total revenue in a year, and the company expects over half of revenue from enterprise and government customers by 2027. Masad also emphasized AI safety and robust agent habitats.
The decision by Replit, a prominent AI coding platform, to switch from Anthropic to OpenAI signals a significant shift in the AI model vendor landscape, affecting the competitive dynamics and adoption of AI models in the developer tools market and potentially influencing advertising and marketing technology applications that rely on such models.

OpenAI Shuts Down Sora; Anthropic Leads Code
OpenAI has shut down its Sora product across app, API and ChatGPT video features after demand declined. At the same time Anthropic’s Claude Code reportedly captured a plurality of the AI coding market (estimated ~42–54%), while OpenAI holds roughly ~20% and trails in U.S. developer usage. The newsletter frames coding as the highest-value AI workload, favoring providers that focused on enterprise workflows. The piece also highlights emerging industry shifts: token-based budgets for engineer model usage (tokenized compensation), Anthropic productizing Claude Code into a managed execution environment similar to OpenClaw but more closed, and Norway’s $2.1 trillion sovereign wealth fund preparing to permit limited agent-driven investment decisions using Anthropic’s Claude under human supervision. The report lists additional AI-related headlines (legal, platform competition, and product launches) and argues these developments could reshape where the agent and software stack is defined.
OpenAI Declares 'Code Red', Refocuses on ChatGPT
OpenAI CEO Sam Altman has declared a “code red,” directing staff to prioritize improving ChatGPT and temporarily shelving or deprioritizing initiatives such as ads, shopping agents and a personal assistant called Pulse. The move is framed as a reaction to intensified competition — notably Google’s Gemini 3, which the newsletter reports outperforming OpenAI’s GPT-5 on certain benchmarks and having a rapidly growing mobile user base. The roundup also catalogs multiple frontier-model releases (e.g., Mistral 3, Runway Gen-4.5, Nvidia’s Alpamayo-R1), legal and financial developments for OpenAI (including a US judge ordering production of 20M anonymized ChatGPT logs and large projected data-center debt), and Anthropic’s IPO preparations and commercial momentum. Broader infrastructure and industry signals — AWS Trainium3, Amazon Nova, and rising demand for data-center construction labor — are also highlighted.
OpenAI Pivots to Enterprise as Anthropic Gains Ground
A newsletter roundup reports OpenAI is cutting consumer 'side quests' (browser, Sora, device efforts) to focus the company on coding and enterprise products after Anthropic captured enterprise mindshare. Fidji Simo framed the move internally as a “code red.” Reuters says OpenAI is in advanced talks with private-equity firms (TPG, Advent, Bain, Brookfield) on a roughly $10 billion joint-venture to accelerate enterprise distribution. Separately, a U.S. federal judge (Rita Lin) blocked the Pentagon’s designation of Anthropic as a supply‑chain risk, finding evidence that the designation was retaliation tied to press comments. The newsletter also highlights broader AI themes: new benchmarks (ARC-AGI 3) challenging model claims, debate over AI’s labor impact (The Atlantic, NBER), and shifting competition around coding-focused LLMs like Claude and OpenAI’s Codex/GPT releases.
