🚀 OpenHands LM 7B v0.1 GGUF Models

OpenHands LM 7B v0.1 GGUF Models offer various formats to meet different hardware and performance requirements. These models are designed for AI network monitoring, providing features like function calling, Nmap scans, and quantum - readiness checks.

🚀 Quick Start

Choosing the Right Model Format

Selecting the appropriate model format is crucial, depending on your hardware capabilities and memory constraints.

BF16 (Brain Float 16) – Use if BF16 acceleration is available

• A 16 - bit floating - point format for faster computation while maintaining good precision.
• It has a similar dynamic range as FP32 but with lower memory usage.
• Recommended for hardware supporting BF16 acceleration. Ideal for high - performance inference with reduced memory footprint compared to FP32.

Use BF16 if:

• Your hardware has native BF16 support (e.g., newer GPUs, TPUs).
• You want higher precision while saving memory.
• You plan to requantize the model into another format.

Avoid BF16 if:

• Your hardware does not support BF16 (it may fall back to FP32 and run slower).
• You need compatibility with older devices lacking BF16 optimization.

F16 (Float 16) – More widely supported than BF16

• A 16 - bit floating - point format with high precision but a smaller range of values than BF16.
• Works on most devices with FP16 acceleration support (including many GPUs and some CPUs).
• Slightly lower numerical precision than BF16 but generally sufficient for inference.

Use F16 if:

• Your hardware supports FP16 but not BF16.
• You need a balance between speed, memory usage, and accuracy.
• You are running on a GPU or another device optimized for FP16 computations.

Avoid F16 if:

• Your device lacks native FP16 support (it may run slower than expected).
• You have memory limitations.

Quantized Models (Q4_K, Q6_K, Q8, etc.) – For CPU & Low - VRAM Inference

Quantization reduces model size and memory usage while maintaining as much accuracy as possible.

• Lower - bit models (Q4_K): Best for minimal memory usage, may have lower precision.
• Higher - bit models (Q6_K, Q8_0): Better accuracy, requires more memory.

Use Quantized Models if:

• You are running inference on a CPU and need an optimized model.
• Your device has low VRAM and cannot load full - precision models.
• You want to reduce memory footprint while keeping reasonable accuracy.

Avoid Quantized Models if:

• You need maximum accuracy (full - precision models are better for this).
• Your hardware has enough VRAM for higher - precision formats (BF16/F16).

Very Low - Bit Quantization (IQ3_XS, IQ3_S, IQ3_M, Q4_K, Q4_0)

These models are optimized for extreme memory efficiency, ideal for low - power devices or large - scale deployments where memory is a critical constraint.

• IQ3_XS: Ultra - low - bit quantization (3 - bit) with extreme memory efficiency.
  • Use case: Best for ultra - low - memory devices where even Q4_K is too large.
  • Trade - off: Lower accuracy compared to higher - bit quantizations.
• IQ3_S: Small block size for maximum memory efficiency.
  • Use case: Best for low - memory devices where IQ3_XS is too aggressive.
• IQ3_M: Medium block size for better accuracy than IQ3_S.
  • Use case: Suitable for low - memory devices where IQ3_S is too limiting.
• Q4_K: 4 - bit quantization with block - wise optimization for better accuracy.
  • Use case: Best for low - memory devices where Q6_K is too large.
• Q4_0: Pure 4 - bit quantization, optimized for ARM devices.
  • Use case: Best for ARM - based devices or low - memory environments.

  • Automated Nmap scans.
  • Quantum - readiness checks.
  • Metasploit integration.

TestLLM – Current experimental model (llama.cpp on 6 CPU threads):

• Zero - configuration setup.
• 30s load time (slow inference but no API costs).
• Help wanted! If you're into edge - device AI, let's collaborate!

All of the code for creating the models and the work I have done with Free Network Monitor is open source. Feel free to use what you find useful. Please support my work and consider buying me a coffee. This will help me pay for the services and increase the token limits for everyone.

Thank you :)

OpenHands LM v0.1

Blog · Use it in OpenHands

This is a smaller 7B model trained following the recipe of [all - hands/openhands - lm - 32b - v0.1](https://huggingface.co/all - hands/openhands - lm - 32b - v0.1).

What is OpenHands LM?

OpenHands LM is built on the foundation of [Qwen Coder 2.5 Instruct 32B](https://huggingface.co/Qwen/Qwen2.5 - Coder - 32B - Instruct), leveraging its powerful base capabilities for coding tasks. What sets OpenHands LM apart is our specialized fine - tuning process:

• We used training data generated by OpenHands itself on a diverse set of open - source repositories.
• Specifically, we use an RL - based framework outlined in SWE - Gym, where we set up a training environment, generate training data using an existing agent, and then fine - tune the model on examples that were resolved successfully.
• It features a 128K token context window, ideal for handling large codebases and long - horizon software engineering tasks.

Performance: Punching Above Its Weight

We evaluated OpenHands LM using our latest [iterative evaluation protocol](https://github.com/All - Hands - AI/OpenHands/tree/main/evaluation/benchmarks/swe_bench#run - inference - rollout - on - swe - bench - instances - generate - patch - from - problem - statement) on the SWE - Bench Verified benchmark.

The results are impressive:

• 37.2% verified resolve rate on SWE - Bench Verified.
• Performance comparable to models with 20x more parameters, including Deepseek V3 0324 (38.8%) with 671B parameters.

Here's how OpenHands LM compares to other leading open - source models:


As the plot demonstrates, our 32B parameter model achieves efficiency that approaches much larger models. While the largest models (671B parameters) achieve slightly higher scores, our 32B parameter model performs remarkably well, opening up possibilities for local deployment that are not possible with larger models.

Getting Started: How to Use OpenHands LM Today

You can start using OpenHands LM immediately through these channels:

1. Download the model from Hugging Face The model is available on [Hugging Face](https://huggingface.co/all - hands/openhands - lm - 32b - v0.1) and can be downloaded directly from there.
2. Create an OpenAI - compatible endpoint with a model serving framework For optimal performance, it is recommended to serve this model with a GPU using [SGLang](https://github.com/sgl - project/sglang) or [vLLM](https://github.com/vllm - project/vllm).
3. Point your OpenHands agent to the new model Download [OpenHands](https://github.com/All - Hands - AI/OpenHands) and follow the instructions for [using an OpenAI - compatible endpoint](https://docs.all - hands.dev/modules/usage/llms/openai - llms#using - openai - compatible - endpoints).

The Road Ahead: Our Development Plans

This initial release marks just the beginning of our journey. We will continue enhancing OpenHands LM based on community feedback and ongoing research initiatives.

In particular, it should be noted that the model is still a research preview, and (1) may be best suited for tasks regarding solving github issues and perform less well on more varied software engineering tasks, (2) may sometimes generate repetitive steps, and (3) is somewhat sensitive to quantization, and may not function at full performance at lower quantization levels. Our next releases will focus on addressing these limitations.

We're also developing more compact versions of the model (including a 7B parameter variant) to support users with limited computational resources. These smaller models will preserve OpenHands LM's core strengths while dramatically reducing hardware requirements.

We encourage you to experiment with OpenHands LM, share your experiences, and participate in its evolution. Together, we can create better tools for tomorrow's software development landscape.
