From Vibe Coding to Vibe Researching: OpenAI’s Mark Chen and Jakub Pachocki

Summary & Insights

The future of research isn’t just about using AI tools; it’s about creating an AI that can autonomously discover new ideas, transforming “vibe coding” into “vibe researching.” OpenAI’s Jakob Pohotsky and Mark Chen outline a clear trajectory where the core mission is to build an “automated researcher,” moving beyond models that simply answer questions to systems that can plan, reason, and innovate over long horizons. GPT-5 represents a major step in this direction by mainstreaming advanced reasoning and agentic behavior, folding the capabilities of their earlier, slower “thinking” models into a default, responsive experience. This shift necessitates a fundamental change in how progress is measured, moving from saturated benchmarks like code competitions to evaluations based on real economic impact and genuine discovery.

The conversation delves into the mechanics of this evolution, explaining why reinforcement learning (RL) continues to defy predictions of plateauing by providing a versatile method to train models within the rich environment of natural language understanding. This approach is key to extending the “reasoning horizon,” allowing AI to tackle complex, open-ended problems that require persistence and adaptation over time, much like a human researcher. Managing the tension between a model’s depth of reasoning and its stability over many steps remains a core focus, as it is essential for achieving true autonomy.

Balancing this ambitious research agenda with product development is a conscious act of prioritization. The leaders emphasize protecting fundamental research from short-term product pressures, allocating resources—especially compute—toward the algorithmic advances that will enable future breakthroughs. They describe a culture that attracts and retains talent by maintaining a clear, conviction-driven focus on frontier problems, fostering constant learning, and embracing the intellectual chemistry that turns disparate explorations into a coherent roadmap toward artificial general intelligence.

Surprising Insights

  • Reinforcement Learning (RL) is the “gift that keeps giving,” consistently yielding performance gains despite widespread predictions that its benefits would plateau, largely because it allows for training on diverse objectives within the robust foundation of a pre-trained language model.
  • The primary constraint for frontier AI research is still compute, not data. Contrary to a popular narrative that the field would become data-constrained, the leaders state that compute remains the decisive bottleneck and the key marginal resource for acceleration.
  • High school students now consider “vibe coding” – describing what they want to an AI – as the default way to program, viewing the manual act of writing code from scratch as an unusual, completeness-seeking exercise.
  • The most important evaluations for future models will measure how long they can operate autonomously, shifting from static benchmarks to dynamic assessments of sustained reasoning and agency.
  • Creating a successful research culture involves intentionally not looking at competitors, focusing instead on internal conviction about long-term goals to avoid the trap of becoming “second place at everything.”

Practical Takeaways

  • For businesses leveraging AI: Prioritize defining “economically meaningful” benchmarks for your use cases, as traditional academic evals are becoming saturated and less indicative of real-world value.
  • Adopt a mindset of “vibe” interaction with AI tools, focusing on clearly articulating problems and desired outcomes rather than micromanaging steps, as the tools are increasingly capable of complex execution.
  • When applying RL or fine-tuning, remember that the methodology will rapidly evolve; avoid over-investing in today’s intricate reward-modeling techniques and stay adaptable to simpler, more human-like learning approaches on the horizon.
  • To foster breakthrough innovation, protect fundamental research efforts from short-term product cycles, allowing researchers the space to work on problems with a one- to two-year horizon without being pulled into immediate feature development.
  • For researchers and engineers: Cultivate both strong conviction in ambitious ideas and ruthless honesty in evaluating progress, learning to distinguish between persevering through challenges and recognizing when a fundamental assumption is flawed.

What comes after vibe coding? Maybe vibe researching.

OpenAI’s Chief Scientist, Jakub Pachocki, and Chief Research Officer, Mark Chen, join a16z general partners Anjney Midha and Sarah Wang to go deep on GPT-5—how they fused fast replies with long-horizon reasoning, how they measure progress once benchmarks saturate, and why reinforcement learning keeps surprising skeptics.

They explore agentic systems (and their stability tradeoffs), coding models that change how software gets made, and the bigger bet: an automated researcher that can generate new ideas with real economic impact. Plus: how they prioritize compute, hire “cave-dweller” talent, protect fundamental research inside a product company, and keep pace without chasing every shiny demo.
