Real-FIM-Eval Benchmark
Real-FIM-Eval is a benchmark to evaluate Fill-in-the-Middle (FIM) capabilities of code LLMs in scenarios that reflect real-world code completion. Real-FIM-Eval is built using data from GitHub commits between Jan. 2025 and Feb. 2025. These commits originate from 228 permissively licensed GitHub repositories with 10,000+ stars, spanning the top 12 widely-used programming languages.
We process git commits using diff_match_patch (https://github.com/google/diff-match-patch) to identify line-level changes. The commits are then categorized into two splits: Add and Edit.
Add(17,879 examples): This split uses git commits where a developer added a new segment of code into an existing file. To create the FIM prompt, we treat the added code segment as the "middle" part that the language model needs to predict. The code surrounding the addition forms the prefix (code before) and the suffix (code after).Edit(13,922 examples): This split uses git commits where a developer modified existing code by removing a segment and replacing it with a new one. We present this task to LLMs in a conflict-merge format. The prompt includes the code context (prefix and suffix) and marks the original code segment (to be removed). The model is asked to infill the updated code segment.
Evaluation Metric
The evaluation metric is character-level perplexity (lower = better), calculated as:
In this formula, p_i represents the probability the model assigns to the i-th token of the ground truth (only the "middle" part that the model is tasked to infill), and n_char(mid) is the total number of characters in that ground truth middle segment.
