Clark moves the date for AI that makes a successor to 2027

Jack Clark, a co-founder of Anthropic, moved the date for AI that makes a successor from 2028 to 2027. The cause is a new test of research skill. On the test, the top model used less than half the computing of the top human experts. That model is from Anthropic. The range of this result is wide.

How the test works

TasteVal is a test from the lab P-Zero Research. It has 8 tasks from AI model work, for example the selection of training data. The model selects the next experiment and uses the results. The test counts the computing that a model uses to get the same scores as the top human experts.

The numbers

The top model, Opus 5.5, has a compute multiplier of 2.3. The range of the result is 1.15 to 4.37. From December 2025, the multiplier increases to 2 times its value in about 3 months, but this range is also wide.

What is not known

One test cannot show a long trend. The authors tell that their results can overstate the speed. The tasks are easy to check, and the human group had no top researchers. The test does not include the selection of a research question. Clark is a co-founder of the company that made the top model.

Insight: The lab at the top also sets the rules

On 14 October, Clark told a Tokyo audience that AI rules must be more strong and AI development more slow. At this time the model of the company of Clark is at the top of the test that moved the date. This reads as a signal: the lab at the top of the test gets a strong voice on the rules. Look for tests from other labs. Leaders must know that the date also shows the position of one lab.
