Executives at artificial intelligence companies may like to tell us that AGI is almost here, but the latest models still need some additional tutoring to help them be as clever as they can.
Scale AI, a company that’s played a key role in helping frontier AI firms build advanced models, has developed a platform that can automatically test a model across thousands of benchmarks and tasks, pinpoint weaknesses, and flag additional training data that ought to help enhance their skills. Scale, of course, will supply the data required.
Scale rose to prominence providing human labor for training and testing advanced AI models. Large language models (LLMs) are trained on oodles of text scraped from books, the web, and other sources. Turning these models into helpful, coherent, and well-mannered chatbots requires additional “post training” in the form of humans who provide feedback on a model’s output.
Scale supplies workers who are expert on probing models for problems and limitations. The new tool, called Scale Evaluation, automates some of this work using Scale’s own machine learning algorithms.
“Within the big labs, there are all these haphazard ways of tracking some of the model weaknesses,” says Daniel Berrios, head of product for Scale Evaluation. The new tool “is a way for [model makers] to go through results and slice and dice them to understand where a model is not performing well,” Berrios says, “then use that to target the data campaigns for improvement.”
Berrios says that several frontier AI model companies are using the tool already. He says that most are using it to improve the reasoning capabilities of their best models. AI reasoning involves a model trying to break a problem into constituent parts in order to solve it more effectively. The approach relies heavily on post-training from users to determine whether the model has solved a problem correctly.
In one instance, Berrios says, Scale Evaluation revealed that a model’s reasoning skills fell off when it was fed non-English prompts. “While [the model’s] general purpose reasoning capabilities were pretty good and performed well on benchmarks, they tended to degrade quite a bit when the prompts were not in English,” he says. Scale Evolution highlighted the issue and allowed the company to gather additional training data to address it.
Jonathan Frankle, chief AI scientist at Databricks, a company that builds large AI models, says that being able to test one foundation model against another sounds useful in principle. “Anyone who moves the ball forward on evaluation is helping us to build better AI,” Frankle says.
In recent months, Scale has contributed to the development of several new benchmarks designed to push AI models to become smarter, and to more carefully scrutinize how they might misbehave. These include EnigmaEval, MultiChallenge, MASK, and Humanity’s Last Exam.
Scale says it is becoming more challenging to measure improvements in AI models, however, as they get better at acing existing tests. The company says its new tool offers a more comprehensive picture by combining many different benchmarks and can be used to devise custom tests of a model’s abilities, like probing its reasoning in different languages. Scale’s own AI can take a given problem and generate more examples, allowing for a more comprehensive test of a model’s skills.
The company’s new tool may also inform efforts to standardize testing AI models for misbehavior. Some researchers say that a lack of standardization means that some model jailbreaks go undisclosed.
In February, the US National Institute of Standards and Technologies announced that Scale would help it develop methodologies for testing models to ensure they are safe and trustworthy.
