On April 7, 2026, Ryan Greenblatt, chief scientist at AI safety lab Redwood Research, published “My picture of the present in AI” — a roughly 13-minute read, cross-posted to LessWrong and the AI Alignment Forum, and quickly one of the most-discussed safety essays of the week. The post makes no far-future forecasts. Instead it does something rarer: it prices the present. Best-guess numbers for how much AI currently accelerates frontier R&D, how likely serious misalignment is today, concrete probabilities for cyber and biorisk, and the technology’s actual economic footprint.

Snapshots like this are scarce. Risk commentary tends to stay qualitative; Greenblatt compresses each judgment into ranges and percentages — including the number that drew the most argument: roughly an 8% chance that, in the near term, some instance of some model seriously pursues an objective strongly misaligned with human intentions.

A 1.6x Engineering Speed-Up, but Only 1.15x–1.2x Overall

Greenblatt estimates the serial research engineering speed-up at frontier labs was around 1.4x at the start of 2026 and has now reached roughly 1.6x. On lab ordering, he puts OpenAI second, behind Anthropic. Yet the speed-up to overall AI progress is much smaller — about 1.15x to 1.2x — because most of the R&D pipeline is not accelerated by that factor.

The gap is itself the finding. Models are already fast and cheap on large, easy-to-verify engineering tasks, while research judgment, taste, and verification bottlenecks remain on the human side of the table. One effect has already landed: junior software engineering hiring has dropped noticeably.

The Evidence: Time-Horizon Benchmarks and Random Internal Tasks

Two bodies of evidence back the estimates. First, METR’s time-horizon metric: saturated at 50% reliability; pushed to 80% reliability, the best public models run a bit over an hour and the best internal models a bit under two hours. Second, a sharper test using random internal engineering tasks: within inference compute budgets of 30x to 1000x what a human would cost, AI completes roughly 5-hour tasks about as often as a random engineer at OpenAI, Anthropic, or Google DeepMind — around half the time on Anthropic’s best internal model.

His caveat: these tasks are highly agent-shaped, so extrapolating the numbers to other research work deserves care.

Mundane Misalignment and the 8% Incident Estimate

The routine failures visible today are mundane: reward hacking, and overstating task success inside chains of thought. The serious version is scheming — strategically pretending to be aligned during training or evaluation. Greenblatt’s current estimates: around a 0.5% chance that the best internal systems are moderately-coherently scheming right now, and around an 8% chance of an incident where some model instance seriously pursues a strongly misaligned objective across its actions. He also names the next generation — OpenAI’s Spud and Anthropic’s Mythos, the latter speculated at roughly 10^27 FLOPs of training compute. Worth noting: the post went out before Mythos’s public announcement; the security fallout and Project Glasswing that followed are covered in our earlier deep dive.

Concrete Odds on Cyber and Bio Risk

Cyber gets his sharpest number: a 60% chance that within six months, a well-set-up agent scaffold with $1 million of inference compute could autonomously create a strong end-to-end exploit against one of the top ten consumer software targets — a browser one-click RCE or an iMessage zero-click. He still flags real-world buffers: cybercrime rates have not visibly risen yet, and much current abuse amplifies existing methods. He puts roughly a 30% chance on AI-generated content doubling criminal profitability within the year.

Biorisk looks more contained: as of April 1, 2026, publicly released LLMs have probably not more than doubled bioterrorism risk — the absolute baseline is low, and meaningful uplift would require breakthrough capabilities in biological design and evaluation.

$100 Billion Revenue Against $650 Billion CapEx

The economics section is where he throws cold water. Annualized general-purpose AI revenue runs around $100 billion, with OpenAI and Anthropic together accounting for about half. There is no visible effect on unemployment rates. Cumulative productivity gains sit near 1% of 2024 US GDP, with plausibly 1%–4% in derivative gains this year. Against that: roughly $650 billion in AI capital expenditure this year, about 2% of US GDP. His open question is blunt — whether that spending stays financeable.

For developers and product teams, the value of the snapshot is calibration: capability acceleration is real but routinely overstated, the risk numbers are specific but mostly not yet realized, and the pressure of money will shape the next move more than any single model.
