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|>
