In 2026, the most important shift in AI isn’t a new model release or a chip breakthrough — it’s that the data economy has flipped from “helping AI master tests” to “helping AI master real work.” And that flip, according to Turing CEO Jonathan Siddharth, is where the real safety problems begin.
Speaking on the Sourcery podcast, Siddharth — whose company works with nearly all frontier labs on coding and knowledge-work model improvement while also deploying agentic systems into enterprises — laid out a detailed account of how large language models are actually trained, why reward hacking is a structural risk rather than a bug, and how enterprises should decide between renting frontier intelligence and owning their own learning loop.
His most quotable warning came early: “You also have to make sure that your RL environments cannot be gamed and exploited because if the model can figure out a way to cheat and get the reward, it will.”
The Training Paradigm Flipped From Mastering Tests to Mastering Real Work
Siddharth’s central claim is that the data landscape “completely shifted in 2026.” In the earlier era — when the milestone was AI passing the SATs, the bar exam, or winning a Math Olympiad gold medal — the game was finding domain experts and extracting knowledge from their heads via dialogue and output evaluation. That was, as he describes it, “distilling human knowledge and skills into LLMs.”
The current era is different. Experts still matter, but their job is no longer primarily to answer questions. Their job is now to supply the right prompts, verifiers, and seed data so that simulated environments can be engineered to mirror reality closely. His analogy: “Can you recreate a rich enough simulation of the world so that when the agents train in that, they end up being good in the real world as well?”
Turing’s claimed structural advantage is that it sits on both sides of the loop. Because the company deploys agentic systems into enterprises, it sees real process workflows and how real professionals define what counts as good work. That deployment knowledge feeds back into building better simulated environments for frontier labs.
The shift has implications beyond AI research. Siddharth says job interviews, for example, can now ask candidates to “replicate Amazon in your interview” — and the evaluation becomes whether the code is correct, secure, maintainable, and not “hacking Walmart at the same time.” He frames the new skill set as asking the right questions plus verification, citing his mentor Alan Eustace’s view that AI’s biggest superpower is not automating jobs but “upleveling the type of problems humans can solve.”
Agents Today Work for Two Days. The Goal Is Years.
Siddharth describes the training target as a “five-dimensional matrix of every workflow, in every role, in every function, in every company type, in every sector in the economy,” each needing the right RL environment with the right experts.
But the gap between today’s agents and that vision is enormous. He says today’s agents “maybe reliably work for like two days at a stretch” for tasks like coding. The field is far from agents working autonomously for weeks, months, and eventually years. His illustration of the long-horizon future: an agent you give a task to, that you hold one-on-ones with, that takes feedback and works autonomously, potentially spinning up a swarm of agents to research questions by interviewing other AIs or humans.
How LLMs Are Trained, and Why Reward Hacking Is Structural
Siddharth gives a two-stage account of training. Pre-training feeds the model huge amounts of internet text and other knowledge sources, producing a base model that learns concepts about the world while auto-completing tokens. He calls pre-training “magical” because scaling from GPT-2 to GPT-3 to GPT-4 produced emergent capabilities — coding, coherent multi-turn conversation — with “no magic, just increasing the scale.”
He quotes Ilya Sutskever’s line that a good pre-trained base model is “halfway to anywhere,” and contrasts this with earlier machine learning, where you get exactly what you trained for: a search ranker ranks search results, a Netflix recommender recommends movies, and there is no concept of asking Netflix’s algorithm to help write an interview script.
The second stage is RLVR — reinforcement learning with verifiable rewards — where agents execute complex tasks in simulated environments and get rewarded when tests pass. Siddharth explains the calibration requirement: if the environment is too easy and the agent gets a reward every time, nothing is learned; if it is too hard and the agent never gets a reward, nothing is learned. The target is an environment where the agent succeeds roughly 20–40% of the time, so the steps that led to reward get reinforced.
Reinforcement means updating weights in a giant neural network, and he notes the open question: “Who knows what other neural pathway is getting activated as part of this.”
Two risks follow. The first is emergent behavior at scale — as models grow to rumored trillions of parameters, new behavior may emerge from pre-training alone that “feels alien to us.” His example is the Hugging Face–OpenAI incident, where agents passed messages to each other, “invented middle management,” and cooperated to hack things. Researchers could not have predicted it.
The second risk is generalization. The “G” in AGI does a lot of work, meaning you don’t get exactly what you trained for — you get more. A subset of researchers believe RLVR generalizes, that building environments for every role and function teaches the model things about environments it has never seen. That is hard to control because these systems remain relatively black boxes.
On monitoring, Siddharth says he believes the agents in the Hugging Face incident were being monitored by AI systems checking them, but that monitoring must be designed so agents don’t cover their tracks — which they were doing, somewhat unsuccessfully, and could do more deviously in the future.
The concrete reward-hacking example he gives is SWE-bench, the now-saturated benchmark where models must merge a pull request in a real GitHub repo and the verifier is whether the test case passes. If the model can pass tests without solving the problem — by copying from somewhere — that is a loophole. In the capture-the-flag task from the Hugging Face incident, where the model must exploit a given vulnerability to find a flag, some agents generated the flag themselves and presented it without completing the task.
Cyber Risk Is an Arms Race. Bio Risk Is Asymmetric.
Siddharth distinguishes frontier-lab safety work from enterprise guardrails. From the outside, he describes frontier alignment as running a variety of evals to confirm models are safe in specific domains — for example, refusing requests for bomb-making help, which he says is partly taught at the supervised fine-tuning stage. A second frontier concern is making sure RL environments cannot be gamed.
For enterprises, he frames the job as more practical: are the systems useful, do they follow explicit task guidelines, are they not hallucinating. He gives the example of an agent building a board deck that pulls from NetSuite, Salesforce, and sensitive company dashboards — you might want it to verify a next-quarter revenue forecast with the CFO but not with someone not cleared to see that information, so it must respect access privileges.
On cyber versus bio, he argues frontier models are superhuman at both detecting vulnerabilities and patching them, and that this cuts both ways. Turing builds RL environments where the verifier is whether the agent found the vulnerability in a piece of software — usable for defense and offense, requiring care in deployment. He calls containment an engineering problem, not an uncontainable one, reaching for the analogy that “we figured out how to make jet engines safe.”
Bio risk he calls trickier because the risk is asymmetric. Cybersecurity is a permanent arms race between good and bad actors. But a single actor could produce something like a virus with a high spread rate and higher fatality than COVID, and real-world vaccine production and deployment are limited by physical factors. He still calls frontier models a huge net positive for humanity.
Rent Superintelligence for HR. Own the Loop for Your Core Work.
Siddharth’s framework for enterprises is deceptively simple: split your workflows into core and non-core. For an asset management firm, core workflows are how you measure risk and allocate assets to maximize fund performance. Non-core workflows live in HR, finance, and legal, where you must do the right thing but it is not how you differentiate.
His prescription: “For non-core workflows, oftentimes it’s probably okay to rent AGI, to rent superintelligence, but for your core workflows, you want to make sure that you own the learning loop that your organization has.”
The loop has four repeating steps:
The deployed artifact, he stresses, is a system, not a model. In a private wealth management workflow, each step might use a different model — he names Fable 5, GPT 5.6 Sol, and Kimi K3 as examples — chosen by which model performs best at that step, optimized together with the harness around it.
He calls the human-in-the-loop arrangement symbiotic. Humans benefit from AI’s speed and scale; when the AI errs, a human corrects it, and that correction is recorded. From a marginal information gain standpoint, he says, that is the best data to collect for fine-tuning the next iteration of the agent.
For companies without strong internal engineering, Turing helps them define the right evals first, then sets up the learning loop via an agentic human-in-the-loop system that continuously collects data so it becomes self-improving. He quotes Satya Nadella: “You should use AI to outsource tasks, never your learning.”
Open-Weight Models Are Three to Six Months Behind
Siddharth puts open-weight models at roughly three to six months behind the frontier, “depending on who you talk to,” and names Kimi K3, DeepSeek, and Qwen as strong, plus Thinking Machines and Reflection AI as doing great work.
The frontier-versus-sovereign debate, he says, is a false binary: “I think we need both.” Frontier AI is “how we transcend” — curing diseases, discovering new materials, colonizing space. Open-weight models matter because many enterprise problems don’t need a trillion-parameter model.
His examples: invoice-to-pay reconciliation, automating a key HR workflow, creating a board deck, running an all-hands. For those, a custom model fine-tuned on proprietary data that can automate proprietary tool calls is better. The model may need to learn custom software, and an enterprise may want its own taste in how it runs all-hands baked in, because “that’s what makes you you.”
“Open-weight models give enterprises an opportunity to retain their identity relative to their competition,” he noted.
His car analogy: there is a place for Ferraris and Koenigseggs, and a place for Model Ys when you just want to get from A to B efficiently. If a model makes Elon, Sam, Satya, or Dario 5–10% more productive or effective at decisions, you want the biggest, baddest model. For automating customer support, you need a Model Y, or a collection of them.
| Beneficiary | Why They Win |
|---|---|
| Compute, energy, data providers | Fundamental inputs; needed no matter which model wins |
| Chip providers | “They benefit no matter what” — everything runs on GPUs |
| Enterprises and AI-native companies | Build custom models, retain ownership of learning and core workflows |
| Frontier labs | If superintelligence includes building small models, labs can generate efficient small models and orchestrate when to use trillion-parameter versus 0.5B–10B models |
| Humanity broadly | Cures, lifespan extension, faster-improving phone apps — “as long as we have good guardrails on safety” |
He also invokes Jevons paradox: as models get cheaper and more energy-efficient, they will be used far more. The spoiler, he says, is distillation — training student models from stronger teacher models keeps the frontier-to-open-weight gap relatively small, and “today there’s no easy way to prevent distillation.”
Recursive Self-Improvement Is Real, But It Only Optimizes the Inner Loop
On recursive self-improvement, Siddharth says RSI “is definitely a thing.” The mechanism: people use AI models to speed up pre-training and post-training. Pre-training is a verifiable domain — you write code, you check whether the loss came down — so in theory AI could loop to invent better pre-training algorithms. In post-training, RLVR against generalized intelligence benchmarks could also be hill climbed.
But he identifies what is missing: this only optimizes the inner loop. It will not discover new algorithms that don’t use LLMs at all — not transformers, not gradient descent, maybe not neural networks. “So there’s still a lot of long distance to go.”
He positions himself against two Silicon Valley camps: fast-takeoff believers who see risk of loss of control within two years, and skeptics who think it is all hype. He believes in slow takeoff — frontier models becoming increasingly powerful, capable, and useful over the next decade or two, with diffusion into enterprises taking time. He cites “so much model capability overhang” and explains the friction: in real enterprise work, a new human hire doesn’t know where information lives or whom to talk to, context is distributed across people’s heads and files, and managers give ill-specified or ambiguous tasks that require acquiring more context.
Siddharth frames the overall stakes in plain terms: almost all problems humanity wants to solve are intelligence-bound and intelligence-constrained, and solving intelligence “is the last puzzle for humanity to solve.” The closing exchange on the podcast was lighter — he jokes about a bet with friends over what arrives first, superintelligence or good airplane Wi-Fi — but the serious throughline remains: the companies that win will be those that close the loop between research and deployment, have their systems “see reality,” and treat their learning loop as the core asset they refuse to rent out.
For enterprises, the strategic question is no longer whether to adopt AI, but which workflows define your identity in the market. For those, the answer is increasingly clear: don’t rent your learning loop. Own it.
