# Ganesh Python v0.1.0
Ganesh Python v0.1.0 is a 12B coding model focused on Python code generation,
code repair and developer-assistant workflows. It is distributed as a
standalone merged checkpoint based on Gemma 4 12B IT. It is developed and
released by the ExecuteSpec R&D Lab.
**Project status (2026-08-27):** supported, frozen research release. A later
unified v0.2 experiment failed its executable specialist-preservation gate and
was not released. Model development is closed; this v0.1 specialist remains
the final published Ganesh Python artifact.
## Intended use
- Python code generation and completion
- Code repair and debugging assistance
- Refactoring and implementation exploration
- Coding-agent and developer-tool evaluation
- Research and experimentation with local or hosted inference
## Model format
- Architecture family: Gemma 4 12B IT
- Weight formats: merged BF16 SafeTensors, GGUF Q8_0 and GGUF Q4_K_M
- Interface: text generation
- Version: v0.1.0
This repository contains a complete standalone model; no additional weight
package is required for inference.
## Usage
Use the tokenizer and processor files included in this repository. Runtime
examples will be added after clean-environment compatibility validation for
Transformers, vLLM and Unsloth.
For local llama.cpp inference, select a file from `gguf/`. Q8_0 prioritizes
fidelity; Q4_K_M reduces memory and storage requirements.
## Evaluation snapshot
On the retained Python executable evaluation, the base scored 16/100 and this
specialist scored 18/100 on development. On the sealed 200-task decision set,
the base scored 14/200 and this specialist scored 23/200. On EvalPlus, the
reported base-to-specialist results were HumanEval 95.1→96.3, HumanEval+
92.1→93.9, MBPP 87.8→88.4, and MBPP+ 73.3→73.8.
These are narrow, versioned evaluation surfaces, not a claim of general coding
superiority. HumanEval-family saturation and historical data availability, and
MBPP training adjacency, materially limit interpretation.
## Limitations
This is an early coding-model release intended for evaluation. It may produce
incorrect, incomplete, insecure or inefficient code; invent APIs; mishandle
edge cases; or fail to follow repository-specific conventions. Generated code
must be reviewed and tested before use. Do not rely on the model for
security-critical, safety-critical or compliance-sensitive decisions without
independent verification.
Performance may vary with prompt format, runtime, precision, sampling settings,
context length and task distribution. Results from one runtime should not be
assumed to transfer unchanged to another.
## Versioning
Ganesh v0.1.0 publishes separate language-focused model identities. No unified
Ganesh successor was released. This repository is frozen except for factual,
safety, licensing, and documentation corrections.
## Attribution
Ganesh Python v0.1.0 is developed and released by the ExecuteSpec R&D Lab and
is based on Gemma 4 12B IT. Use of this model remains subject to the applicable
Gemma Terms of Use and Gemma Prohibited Use Policy.
