# Holo-3.1-4B Coding Merged Model

## Overview

This repository contains a merged Transformers checkpoint produced from `Hcompany/Holo-3.1-4B` and the companion coding LoRA adapter. It is intended for users who prefer loading a standard merged model rather than applying a PEFT adapter at runtime.

## What Is Included

- Merged model weights in sharded `safetensors` format.
- Model configuration and generation configuration.
- Tokenizer and chat template files.
- A model card summarizing the measured coding adaptation result.

## Training And Evaluation Summary

The underlying adapter was trained with supervised fine-tuning on curated coding instruction data. Evaluation used an 80-task held-out greedy decoding probe drawn from HumanEval-style and MBPP-style tasks.

Measured result on the held-out probe:

- Base model: 24 / 80 tasks passed.
- Adapted model: 31 / 80 tasks passed.
- Relative lift over the measured base result: 29.17%.

The merged model should match the adapter-applied behavior, subject to normal numerical and runtime differences.

## Intended Use

Use this checkpoint for coding assistance experiments, Python function generation, lightweight algorithmic problem solving, and local inference workflows that expect standard Transformers model files.

## Known Limitations

- The evaluation probe is small and does not cover all programming languages or repository-scale workflows.
- The model can produce incorrect code, incomplete reasoning, or solutions that fail edge cases.
- Generated code should be reviewed, tested, and sandboxed where appropriate.
- The checkpoint inherits limitations and licensing terms from the base model and adaptation data sources.

## File List

- `model-00001-of-00009.safetensors` through `model-00009-of-00009.safetensors`: merged model shards.
- `model.safetensors.index.json`: shard index.
- `config.json`, `generation_config.json`: model configuration files.
- `tokenizer.json`, `tokenizer_config.json`, `chat_template.jinja`: tokenizer/chat assets.
- `README.md`: this model card.

## Reproducibility And Provenance

The model was produced by merging a PEFT LoRA coding adapter into `Hcompany/Holo-3.1-4B` and saving the result as sharded `safetensors`. Companion evaluation and training provenance artifacts are available in the LoRA repository.
