# Zeta 2.1
Zeta 2.1 is a code edit prediction (also known as next-edit suggestion) model finetuned from `ByteDance-Seed/Seed-Coder-8B-Base`.
Given code context, edits history and an editable region around the cursor, it predicts the rewritten content for that region.
- **Developed by:** Zed Industries
- **License:** Apache-2.0
- **Fine-tuned from:** ByteDance-Seed/Seed-Coder-8B-Base
- **Model version:** 0323-multi-region-filtered-r3
## Prompt format
The model uses a SPM (suffix-prefix-middle) style prompt with numbered multi-region markers for editable regions:
Here is a minimal example:
```
<[fim-suffix]>
code after editable region
<[fim-prefix]><filename>related/file.py
related file content
<filename>edit_history
--- a/some_file.py
+++ b/some_file.py
-old
+new
<filename>path/to/target_file.py
code before editable region
<|marker_1|>
code that
needs to<|user_cursor|>
be rewritten
<|marker_2|>
<[fim-middle]>
```
Expected output (should be generated by the model, without backticks):
```
<|marker_1|>
revised content for
the editable region
<|marker_2|>
```
Here is a real-world example:
