zeta-2.1-GGUF

Zeta 2.1 — GGUF

GGUF quantizations of zed-industries/zeta-2.1, a code edit prediction (next-edit suggestion) model from Zed Industries.

These files were produced from the original BF16 safetensors using llama.cpp b9085 (convert_hf_to_gguf.py → llama-quantize). No fine-tuning or weight modification beyond format conversion and quantization.

Quickstart

Ollama

ollama pull hf.co/adilkairolla/zeta-2.1-GGUF:Q4_K_M

Replace the tag with Q5_K_M, Q8_0, or f16 for a different quant. Zeta is a code-edit-prediction model (not a chat model) — call it via /api/generate with the FIM prompt below, not via /api/chat.

LM Studio

Search for adilkairolla/zeta-2.1-GGUF in the model browser and pick a quant. LM Studio loads it as a base completion model.

llama.cpp

# One-shot completion (correct binary for non-chat models)
./llama-completion -m zeta-2.1-Q4_K_M.gguf -p "$(cat your-prompt.txt)" -n 256 -c 4096

llama-cpp-python

from llama_cpp import Llama
llm = Llama(model_path="zeta-2.1-Q4_K_M.gguf", n_ctx=4096)
out = llm(prompt, max_tokens=256, stop=["<|marker_2|>"], echo=False)
print(out["choices"][0]["text"])

Prompt format

Zeta uses a Suffix-Prefix-Middle (SPM) FIM format with numbered region markers. Quoting the upstream model card:

<[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:

<|marker_1|>
revised content for
the editable region
<|marker_2|>

See the upstream sample.prompt and sample.output for a real example.
