Requirements
  • Have strong hands-on experience training, evaluating, or debugging large machine learning models, especially large language models (LLMs).
  • Have excellent engineering skills in Python and modern machine learning frameworks such as PyTorch.
  • Bring mathematical rigor, quantitative taste, and comfort turning ambiguous research questions into measurable experiments.
  • Have experience with reinforcement learning, post-training, preference optimization, scalable oversight, model evaluation, or adjacent empirical machine learning research.
  • Can operate with high independence and do not need close day-to-day handholding.
  • Enjoy fast-paced, collaborative research environments where priorities shift as models and evidence change.
  • Have a strong record in technical problem solving, such as competitive programming, math contests, systems work, or similarly rigorous engineering and research projects.
  • Care about building artificial intelligence systems that are trustworthy, honest, and reliable in high-stakes settings.
  • Are motivated by making concrete progress on alignment methods that can be tested, trained, published, and deployed.
Responsibilities
  • Design and implement alignment experiments focused on intent following, honesty, calibration, and robustness.
  • Train and evaluate models using reinforcement learning, and other empirical machine learning methods.
  • Develop evaluations for failure modes such as hallucination, instruction-following failures, reward hacking, covert actions, and scheming.
  • Study methods that encourage models to verify their behavior and report shortcomings honestly, including confession-style training objectives.
  • Build monitoring and inference-time interventions that ensure compliant behavior or surface model issues to users or downstream systems.
  • Investigate how alignment methods scale with model capability, compute, data, context length, action length, and adversarial pressure.
  • Integrate successful techniques into model training and deployment workflows.
  • Produce externally publishable research when results advance the broader science of alignment.
  • Collaborate with researchers and engineers across post-training, RL, evaluations, safety, and product-facing teams.

OpenAI conducts AI research and deployment to build advanced AI models and tools that help people automate tasks, be more creative, and make better decisions. Its products include ChatGPT, a conversational AI that can write, code, tutor, and assist in interactive tasks, and Sora, which can generate videos from text prompts. OpenAI’s models typically run through cloud-based services and subscriptions, with licensing and partnerships for broader use. The company operates a capped-profit model to balance generating revenue with ensuring safety, ethics, and long-term societal benefits. Its approach emphasizes safety, responsible deployment, and collaboration with researchers, governments, and institutions. The goal is to ensure artificial general intelligence, when it arrives, benefits all of humanity and minimizes risks.

What believers are saying

  • ChatGPT commerce integrations can convert conversational usage into direct transactions.
  • Regulated-industry partnerships deepen enterprise penetration in healthcare, finance, and compliance workflows.
  • Memory, biology, and premium model advances can increase retention and revenue per user.

What critics are saying

  • Microsoft's MAI-Thinking-1 reduces OpenAI's strategic dependence and weakens platform lock-in.
  • Agentic errors in search, coding, and commerce can trigger enterprise and consumer trust losses.
  • Biology and regulated-workflow deployments create severe safety, legal, and reputational exposure.

What makes OpenAI unique

  • OpenAI combines frontier research with deployment through ChatGPT, Codex, and Sora.[1][6]
  • Its capped-profit structure ties commercialization to an AGI-benefit mission.[5][7]
  • Deep integrations with Pipedrive, Wix, D&B, and Wolters Kluwer expand workflow reach.

OpenAI commits over $225M to Singapore, launches first Applied AI Lab outside US

OpenAI has committed over S$300 million (approximately $220 million) to Singapore's artificial intelligence ecosystem, establishing its first Applied AI Lab outside the United States. The partnership, formalised through a memorandum of understanding with Singapore's Ministry of Digital Development and Information, was announced during the ATxSummit. The initiative focuses on deploying AI across public services, finance, healthcare, education and digital infrastructure. Around 200 specialised roles, including forward-deployed engineers, will be created over the coming years to support implementation with companies and government partners. The programme will include talent development, enterprise adoption support and AI safety frameworks. OpenAI will conduct training initiatives to build local technical capabilities. The investment positions Singapore as a regional operational hub for AI deployment in Southeast Asia.

CSU spends $30M on OpenAI deal despite student and faculty scepticism about AI in education

The California State University system has renewed its contract with OpenAI for $13 million annually over three years, following an initial $17 million deal, aiming to become the first AI-powered institution of its kind in the US. The partnership provides ChatGPT Edu to roughly 470,000 students, faculty and staff across 22 campuses. However, a recent survey of over 94,000 respondents revealed widespread scepticism. Roughly 65% of students and 59% of faculty doubted AI's educational benefits, whilst large majorities worried about impacts on creativity, job security and the environment. About 80% of students said they wouldn't feel comfortable submitting AI-generated work as their own. CSU officials defended the no-bid contract as essential for preparing students for an AI-driven workforce, noting that only around a quarter of ChatGPT users accessed the university-provided version.

Cerebras lands $27B OpenAI deal, heads for $47B IPO after handing away $5B stake

Cerebras Systems is set to list this week at a $47 billion valuation, a dramatic increase from its abandoned IPO attempt 18 months ago. The AI chipmaker's fortunes changed after securing OpenAI as a customer, providing Sam Altman's company with 750 megawatts of computing power for three years in a deal worth approximately $27 billion. The arrangement isn't cheap. Cerebras is granting OpenAI warrants potentially worth $5 billion, representing a tenth of the company's shares—roughly half the deal's expected profit. However, the OpenAI partnership has transformed Cerebras's prospects, helping it secure a valuation of 15 times sales, richer than Nvidia. The strategy mirrors OpenAI's previous deals with AMD and Nvidia, where partnerships boosted chipmakers' valuations whilst providing OpenAI with crucial computing infrastructure.

Y Combinator’s Stake in OpenAI

The fact that Paul Graham personally has billions of dollars at stake with OpenAI doesn’t mean that his public opinion on Sam Altman’s trustworthiness and leadership is invalid. But it certainly seems like the sort of thing that ought to be disclosed when quoting Graham as an Altman character reference.
