For years, Big Tech has promised AI agents that can handle everyday tasks with minimal human input. Yet when you try today’s consumer agents — from OpenAI’s ChatGPT Agent to Perplexity’s Comet — their limitations quickly become clear. To move forward, Silicon Valley bets big on ‘environments’ to train AI agents, a strategy that could reshape the industry.

Why AI Agents Need Environments
The current wave of AI breakthroughs was powered by massive labeled datasets. But as researchers push for more capable AI agents, datasets alone aren’t enough. Instead, carefully designed reinforcement learning (RL) environments are becoming essential to train agents on multi-step, real-world tasks.
Think of environments as interactive workspaces where AI agents can practice, fail, and improve. Just as flight simulators train pilots safely, RL environments provide AI with a space to learn complex problem-solving before going live.
The Race to Build RL Environments
Top investors and researchers agree that demand for RL environments is skyrocketing. “All the big AI labs are building RL environments in-house,” said Jennifer Li, general partner at Andreessen Horowitz. But creating these simulations is highly complex, sparking opportunities for third-party startups that can deliver high-quality environments at scale.
This shift has already given rise to a new class of well-funded startups, including Mechanize and Prime Intellect, both aiming to dominate the environment-building market. Meanwhile, established data-labeling firms like Mercor and Surge are pivoting to RL environments to stay relevant as the industry transitions away from static datasets.
Billion-Dollar Bets from Major AI Labs
The financial stakes are massive. According to The Information, leaders at Anthropic have discussed investing more than $1 billion in RL environments over the next year. For investors, the dream is that one company will become the “Scale AI for environments,” mirroring how Scale AI fueled the chatbot boom.
This environment-driven approach signals a fundamental change: instead of training AI only on text and images, companies now want to simulate entire digital workspaces, giving agents the ability to perform sequences of actions — from booking travel to automating office workflows.
Will Environments Deliver on the Hype?
The big question is whether RL environments will truly unlock the potential of AI agents. Advocates argue they are the missing link needed to move from chatbots to fully autonomous digital workers. Critics warn that scaling these environments may take far more time and resources than expected.
Still, the momentum is undeniable. With Silicon Valley betting big on environments to train AI agents, startups, investors, and major labs are preparing for what could be the next billion-dollar AI gold rush.
