RLM: The Future of Code-to-Metric Predictions

Predicting numeric outcomes from code execution has always been a tough nut to crack. The complexity of programming languages adds a significant hurdle. Yet, a new Regression Language Model (RLM) is changing the game. By using a frozen large language model (LLM) encoder, this RLM sidesteps the need for heavy feature engineering. That's a win for developers everywhere.

Unified Predictions Across Languages

Gone are the days when each programming language required its own custom tweaks for prediction. This RLM can handle the memory footprint of various high-level languages, including Python and C++. It also predicts latency for Triton GPU kernels and assesses both accuracy and speed for neural networks in the ONNX format.

The numbers tell a different story than past efforts. A relatively modest 300 million parameter RLM, drawing on T5Gemma, scores over 0.9 in Spearman rank on competitive programming submissions from APPS. And across 17 languages from CodeNet, it averages over 0.5. That’s impressive.

A New Benchmark in Hardware Prediction

Hardware predictions have long been the domain of graph neural networks. But this RLM is stepping up. It achieves the highest average Kendall-Tau of 0.46 across five classic NAS design spaces. That’s not just a footnote. It’s a headline.

Why does this matter? The reality is, as programming and model architectures grow more complex, the need for efficient, unified prediction tools becomes important. Who wouldn’t want a single model that predicts architecture latencies on numerous hardware platforms?

Stripping Back Complexity

Strip away the marketing, and you get a tool that simplifies the coder’s life. It's a bold move towards unifying predictions without sacrificing accuracy. The focus on a single unified model means less time wrangling code and more time innovating.

Here’s what the benchmarks actually show: a shift from specialized models to versatile, adaptable tools. Frankly, it’s a lesson in efficiency. The architecture matters more than the parameter count.

Where do we go from here? It's time to rethink how we approach code-to-metric tasks. This RLM might just be the model to light the way.
