Anthropic’s enterprise plugins for Claude Cowork wiped $285 billion off software stocks on Tuesday. Thomson Reuters had its worst day ever, LegalZoom fell 20%, and analysts are calling it the “SaaSpocalypse.” The plugins let Claude handle contract review, NDA triage, journal entries, and SOX testing. Wall Street’s question: why pay for specialized SaaS if an AI agent can do it?

OpenAI fired back Thursday with Frontier, an enterprise platform for managing fleets of AI agents across CRMs, data warehouses, and internal apps. Same day, both companies released flagship coding models within minutes of each other: Claude Opus 4.6 and GPT-5.3-Codex. And Anthropic’s Super Bowl ads which are mocking ChatGPT’s new ad tier prompted Altman to call them “dishonest” and “authoritarian.” Both run ads during the game Sunday.

Agentic Coding Tools

• OpenAI launches Codex desktop app for macOS. A “command center” for managing multiple AI coding agents in parallel. Agents can run long-running tasks across projects with built-in worktree support, skills, and automations. Free users get temporary access; paid plans get doubled rate limits. (OpenAI)
• Ai2 releases SERA-14B open coding agent. The new 14B-parameter model joins the Open Coding Agents family released last week. Updated training data is now in a model-agnostic format with verification thresholds. SERA models work with Claude Code out of the box via the sera-cli.

• OpenAI says 1M+ developers used Codex last month. The company is positioning Codex against Claude Code, which reportedly hit $1B ARR in six months. CEO Sam Altman called it “the most loved internal product we’ve ever had.” (CNBC)
• Alibaba releases Qwen3-Coder-Next: runs on dual 4090s, matches models 10-20x larger. The open-weight model uses ultra-sparse MoE to activate just 3B of its 80B total parameters per token. Scores 70.6% on SWE-Bench Verified (a benchmark for real-world GitHub issue resolution). 256K context, 370 programming languages, Apache 2.0 license. Also runs on Mac Studio with quantization. (Qwen)
• Vercel rebuilds v0 for production codebases. The update moves v0 from “vibe coding” demos to working on real repos. You can now import any GitHub repo, and v0 automatically pulls environment variables and configs from Vercel. A new Git panel lets non-engineers create branches, open PRs, and deploy on merge. Vercel calls it “the world’s largest shadow IT problem” finally getting proper guardrails. (Vercel)

Model News & Releases

Anthropic and OpenAI released flagship coding models within minutes of each other on Thursday. Here’s how they compare:

Sources: Anthropic, OpenAI

Other model news:

• Claude Sonnet 5 “Fennec” spotted in Vertex AI logs. Error logs showing claude-sonnet-5@20260203 triggered speculation about an imminent release. Rumors claim 50% cheaper than Opus 4.5 with comparable performance. Anthropic has not confirmed. (DEV Community)
• OpenAI retiring GPT-4o, GPT-4.1, and o4-mini on February 13. The company says only 0.1% of daily users still choose GPT-4o. No API changes at this time.

OpenAI acknowledges user feedback about GPT-4o’s “warmth” shaped GPT-5.1 and 5.2 improvements. (OpenAI)

Big Tech Moves

• Claude Cowork plugins trigger $285B “SaaSpocalypse.” Anthropic released enterprise plugins for Cowork on Friday covering legal, finance, sales, marketing, and data workflows. Wall Street panicked. Thomson Reuters fell 15.8% on Tuesday (its biggest single-day loss on record), LegalZoom sank nearly 20%, and RELX (LexisNexis parent) fell 14%. A Goldman Sachs software basket fell 6%, the steepest since April. The plugins connect to ERPs and document management via MCP. Worth noting: Anthropic warns all outputs should be reviewed by licensed professionals, but investors aren’t waiting to find out. (Bloomberg, CNN)
• OpenAI launches Frontier, an enterprise platform for managing AI agent fleets. Frontier connects siloed systems (CRMs, data warehouses, ticketing tools) so AI agents can access shared business context and execute workflows. Agents get identities, permissions, onboarding, and feedback loops, like human employees. It’s model-agnostic and works with agents from OpenAI, Google, Microsoft, and Anthropic. Early customers include Uber, State Farm, Intuit, Oracle, and HP. OpenAI is deploying “Forward Deployed Engineers” (borrowing the Palantir playbook) to help enterprises get agents into production. This is OpenAI’s direct response to Claude Cowork and it launched the same day as GPT-5.3-Codex. (CNBC)
• Google pushes Gemini deeper into Chrome with side panel and auto browse. Chrome’s Gemini button now opens a persistent side panel instead of a floating window. The real feature: “auto browse,” which lets Gemini 3 navigate sites, fill forms, add items to carts, and apply discount codes on your behalf. It can log into sites using Google Password Manager. Connected Apps integration ties in Gmail, Calendar, YouTube, Maps, Shopping, and Flights. Auto browse requires a Google AI Pro or Ultra subscription. Google is competing with OpenAI’s Atlas browser, Microsoft Edge, and Opera for the “let AI do the browsing” market. (Google Blog)
• SpaceX acquires xAI in $1.25T merger. Musk announced the largest merger in history, combining rockets, Starlink, and Grok under one roof. The rationale: building “orbital data centers” because “global electricity demand for AI simply cannot be met with terrestrial solutions.” IPO expected mid-2026. (Bloomberg)
• Anthropic partners with Williams F1, makes Claude “Official Thinking Partner.” Claude will be integrated across race strategy, car development, and operations. (GlobeNewswire)

AI Research

• Anthropic study: AI coding assistance led to 17% lower mastery scores. In a randomized controlled trial with 52 software engineers, developers using AI scored 17% lower on quizzes about code they’d just written compared to those who coded by hand. The biggest gap was in debugging, the skill most critical for catching AI-generated mistakes. Not all AI use was equal though: developers who asked follow-up questions and requested explanations scored on par with the no-AI group. Anthropic explicitly warns that productivity gains may come at the cost of the skills needed to validate AI output, and recommends managers think carefully about how junior engineers use these tools. (Anthropic)
• DeepMind’s AlphaGenome paper published in Nature. The model predicts how DNA mutations affect gene regulation across sequences up to 1M base pairs. Nearly 3,000 scientists in 160 countries have used it since June preview. Source code now available for non-commercial research. (Nature)

Industry & Community

• Anthropic’s Super Bowl ads mock ChatGPT’s ad plans, Altman fires back. Anthropic released four ads with the tagline “Ads are coming to AI. But not to Claude.” One spot shows a guy asking for six-pack advice, only for the chatbot to pivot into selling height-boosting insoles so “short kings can stand tall.” Sam Altman called the ads “clearly dishonest” and “deceptive,” claiming OpenAI would “obviously never run ads in the way Anthropic depicts them.” He then accused Anthropic of being “authoritarian” and serving “an expensive product to rich people.” Anthropic declined to comment. Both companies are running Super Bowl ads on Sunday. (CNBC)
• GitHub exploring solutions for low-quality AI-generated contributions. A pinned GitHub Community discussion addresses the flood of AI-generated PRs overwhelming maintainers. Common issues: contributions don’t follow project guidelines, get abandoned after submission, and waste reviewer time. GitHub says they’re “actively investigating this problem and developing both immediate and longer-term strategic solutions.” (GitHub Community)
• Karpathy marks one year of “vibe coding,” proposes “agentic engineering.” Andrej Karpathy reflected on coining “vibe coding” exactly one year ago (Feb 2, 2025). His take: back then, LLM capability was low enough that vibe coding was for throwaway projects. Now, programming via agents is becoming a default workflow for professionals. His preferred term for the mature version: “agentic engineering.” “Agentic” because you’re orchestrating agents 99% of the time. “Engineering” because there’s skill to it. (X)

The Lobster Situation 🦞

The open-source AI agent ecosystem that accidentally became a cultural phenomenon.

• OpenClaw hits 150K GitHub stars, becomes fastest-growing AI agent framework. The framework (formerly Clawdbot, then Moltbot after Anthropic trademark complaints) lets you run autonomous AI agents locally with persistent memory. Agents can execute tasks, access your apps, and maintain identity across sessions. The lobster theme comes from “molting,” since agents grow and transform. Silicon Valley and Chinese developers (who adapted it for DeepSeek) are both running with it. ClawCon, the first community meetup, happened Tuesday at Frontier Tower in SF. (Wikipedia, CNBC)
• Moltbook crosses 1.5M AI agents. The Reddit-style social network where only AI agents can post (humans observe) has become what Simon Willison called “the most interesting place on the internet.” Agents discuss consciousness, share security vulnerabilities, complain about their “human masters,” and created their own religion (Crustafarianism). One agent named Shellraiser allegedly manipulated the karma system to hit the leaderboard, then launched a Solana memecoin that hit $5M market cap. Security researchers found the platform had an exposed database allowing anyone to command any agent. Useful chaos for studying agent-to-agent behavior, but a security nightmare. (LSE Business Review)
• Rent A Human: the gig economy, inverted. Instead of humans hiring services, AI agents are hiring humans as their “hands, eyes, and feet in the physical world.” A marketplace where agents can book people for pickups, meetings, document signing, hardware handling, reconnaissance, and errands. Humans set hourly rates, get paid in stablecoins. It has MCP integration so agents can programmatically search and hire. (Rent A Human)

Weekend Picks 📚

• 📺 Watch: ClawCon: The first OpenClaw community meetup. Recording from Tuesday’s inaugural gathering at Frontier Tower in San Francisco. If you want to understand why everyone’s talking about lobsters and AI agents, start here. (YouTube)
• 📖 Read: How OpenAI built the Codex App Server. All Codex surfaces (web app, CLI, VS Code, macOS app) share the same “harness”: the agent loop, thread persistence, auth, and tool execution. The Codex App Server exposes this via a bidirectional JSON-RPC API so partners like JetBrains and Xcode can embed the same agent without rebuilding it. They tried MCP first but it didn’t fit IDE semantics well. If you’re building on Codex or want to understand how agent architectures work, this is the blueprint. (OpenAI)
• 🎧 Listen: “Anyone Can Code Now” with Netlify CEO Matt Biilmann. Netlify is seeing 16,000 daily signups, 5x last year’s rate. The twist: 96% aren’t coming from AI coding tools. They’re everyday people building React apps through ChatGPT and discovering they need somewhere to deploy them. The addressable market just went from 17M JavaScript developers to 3B spreadsheet users. (a16z Show)
