Tiny Pickle v3 Coder — MLX 4-bit

Tiny Pickle v3 Coder is a coding-focused adaptation of Qwen/Qwen3-Coder-30B-A3B-Instruct, converted to MLX and quantized for Apple Silicon.

Model lineage

• Base model: Qwen/Qwen3-Coder-30B-A3B-Instruct
• LoRA adapter: vsan/tiny-pickle-v3-coder-LoRA
• Merged Safetensors: vsan/tiny-pickle-v3-coder
• Quantization: MLX affine 4-bit
• Group size: 64
• Converted directory size: 16G

Installation

pip install -U mlx-lm

Interactive chat

mlx_lm.chat --model mlx-community/Tiny-Pickle-v3-Coder-4bit

Command-line generation

mlx_lm.generate \
  --model mlx-community/Tiny-Pickle-v3-Coder-4bit \
  --prompt "Write a tested Python implementation of an LRU cache." \
  --max-tokens 800

Intended use

Code generation, debugging, code review, implementation planning, test generation, and local software-engineering assistance on Apple Silicon.

Quantization

This release uses MLX 4-bit affine quantization with group size 64. Quantization reduces storage and unified-memory requirements but may alter outputs or reduce quality relative to the merged BF16 model.

Limitations

Tiny Pickle v3 Coder is experimental and has not yet been independently demonstrated to outperform its base model. Generated code may be incorrect, insecure, incomplete, or non-functional and must be reviewed and tested.

Local Performance

The following result is a single local inference measurement, not a standardized benchmark.

Test prompt

You are reviewing a Python async web crawler. Implement a complete, production-quality crawler that uses asyncio and aiohttp; limits global concurrency to 20; limits each domain to 2 concurrent requests; respects robots.txt; retries HTTP 429 and 5xx responses with exponential backoff and jitter; avoids duplicate URLs; normalizes relative links; restricts crawling to the starting domain; supports cancellation; records failures without stopping the crawl; and includes pytest tests using mocked HTTP responses. Return one self-contained Python module followed by the tests.

Results can vary with the macOS version, MLX-LM version, background processes, context length, sampling configuration, and thermal state.
