OpenAI and Anthropic are bitter enemies. Sam Altman sent a “code red” memo as Claude Opus 4.5 crushed ChatGPT on benchmarks. Google’s Gemini 3 Pro joined the beatdown. Three flagship AI models dropped in six weeks of all-out war. Then, on December 9, something bizarre happened: these fierce rivals united under the Linux Foundation to launch the Agentic AI Foundation, contributing their most valuable open-source assets to standardize AI agents.
Why would companies locked in existential competition suddenly cooperate? The answer isn’t altruism. It’s regulatory arbitrage.
What They Contributed
The AAIF launches with three major technical contributions that solve real fragmentation problems developers face daily.
Anthropic’s Model Context Protocol (MCP) is a universal standard for connecting AI models to tools and data. Think HTTP for AI agents. Before MCP, integrating M different LLMs with N different tools required M×N custom integrations – exponential complexity. MCP reduces this to M + N integrations. It’s already widely adopted, using JSON-RPC 2.0 and inspired by the Language Server Protocol.
OpenAI’s AGENTS.md is a simple Markdown format for guiding coding agents. It’s literally “a README for agents” – you drop an AGENTS.md file in your project root with setup commands, testing workflows, and coding style preferences. The format is already adopted by over 60,000 open-source projects and works across Cursor, GitHub Copilot, Devin, VS Code, and Jules. No rigid structure, just standard Markdown.
Block’s Goose framework is an open-source, local-first AI agent that actually ships. It saves Block teams 50-75% of development time, and 60% of their workforce uses it weekly. Unlike vaporware demos, Goose runs on your machine, executes tasks autonomously, and works with any LLM – not locked to one provider.
These aren’t experimental toys. They’re production-ready tools with proven ROI and massive adoption.
The Real Story: Regulatory Pressure
Here’s what nobody’s saying loudly: this isn’t cooperation, it’s strategic survival.
The EU is considering expanding the Digital Markets Act to classify AI businesses as “gatekeepers,” potentially mandating interoperability between AI systems. US antitrust regulators are watching market consolidation – five firms control roughly 90% of the foundation model market. As one industry report notes, “As agentic AI makes critical decisions, it could unknowingly lead to anticompetitive behavior, exposing companies to regulatory scrutiny.”
Translation: Standardize now or get regulated later. By donating their protocols to the Linux Foundation, these companies are writing the rules before governments do. Smart strategy, not charity.
There’s also the fragmentation risk. Early AI agent projects built custom APIs and task formats – walled gardens that frustrated developers and threatened vendor lock-in. Standards expand the market for everyone by reducing switching costs and enabling ecosystem growth. OpenAI, Anthropic, Google, and Microsoft all benefit more from a large standardized market than from fragmented fiefdoms.
What Developers Should Do
Adopt these standards immediately, but understand the power dynamics.
Add AGENTS.md to your projects. If 60,000 projects are using it and every major coding assistant supports it, you’re behind if you’re not. It’s just Markdown – takes five minutes.
Use MCP for AI integrations. Building features that connect AI models to tools or data? MCP is the standard now. Future-proof yourself instead of building custom integrations that’ll get deprecated.
Experiment with Goose. Open-source, runs locally (privacy win), works with any LLM, and has real productivity numbers. Block’s 50-75% time savings aren’t marketing fluff – they’re using it in production.
But stay vigilant. Watch who controls AAIF technical decisions. Notice who’s missing from the platinum members list – no Meta, no xAI, no Mistral, no smaller AI startups. Standards defined by incumbents tend to favor incumbents. The Linux Foundation brings proven neutral governance, but “neutral” doesn’t mean “powerless incumbents.”
The Verdict
The Agentic AI Foundation is useful and cynical in equal measure. Developers get genuinely good tools that solve real problems. The standards prevent fragmentation and enable portability. That’s valuable.
But don’t mistake coopetition for cooperation. These companies aren’t uniting out of benevolence – they’re positioning strategically ahead of regulation, influencing standards they’ll have to follow anyway, and consolidating control while claiming openness.
Adopt the tools. They work. Just understand whose interests they serve.
