Andrej Karpathy, co-founder of OpenAI and former Director of AI at Tesla, announced on Monday that he is joining Anthropic. After focusing on AI education for the past two years via his startup Eureka Labs, Karpathy will now work within Anthropic’s pre-training unit under the leadership of Nick Joseph.

Karpathy’s career has been central to major AI milestones, including a tenure at OpenAI (2015-2017) and leading Tesla’s Autopilot team until 2022. In January 2026, he famously identified a "phase shift" in software engineering, coining the term "vibe-coding" to describe the transition to agent-led development. He noted that AI coding agents crossed a critical coherence threshold in December 2025.

This move follows a series of high-profile transitions from OpenAI to Anthropic, including co-founder John Schulman in August 2024. Karpathy stated that the next few years at the frontier of Large Language Models (LLMs) will be "especially significant," citing this as the primary reason for his return to active research and development.

OpenAI CEO Sam Altman stated the company must transition into an AI inference business, reflecting an industry shift as GitHub announced it will move Copilot from fixed-rate to consumption-based billing on June 1, 2026. The change is driven by the massive surge in compute usage caused by autonomous AI agents.

Major AI providers are currently heavily subsidizing corporate subscriptions. Microsoft lost over $20 per user monthly on GitHub Copilot, with heavy users costing up to $80 on a $10 subscription. Similarly, a $20 Claude Pro subscription can consume $200 to $400 worth of compute at standard API rates, and Anthropic users reportedly burn $8 in compute for every $1 in revenue. To support this scale, OpenAI projects a $115 billion cash burn by 2029, while Oracle took on $43 billion in debt in a single year to build infrastructure.

As AI laboratories prepare for public offerings, the pressure to achieve profitability will force an end to subsidized pricing, requiring corporate clients to drastically recalculate their IT budgets.
