Overview

This is the official GGUF quantized release of Nexora-Vector-v0.1, published by [Open4bits](https://huggingface.co/Open4bits) — the official quantization project under ArkAiLabs. Multiple quantization levels are provided to suit different hardware configurations, from low-VRAM and CPU-only setups to higher-fidelity deployments.

The base model is a supervised fine-tuned variant of Qwen3-4B-Instruct, adapted specifically to generate structured vector graphics in SVG format from natural language instructions.

This release is in beta and is intended for research, experimentation, and early-stage design tooling. All outputs should be validated before use in any downstream pipeline.

Available Quantizations

QuantizationBitsFile SizeRecommended For
Q2_K2-bit1.67 GBMinimal memory, CPU-only, lowest quality
IQ3_XXS3-bit1.67 GBVery low memory, better than Q2_K
IQ3_M3-bit1.96 GBLow memory with improved quality over IQ3_XXS
IQ4_XS4-bit2.27 GBCompact 4-bit with good quality
IQ4_NL4-bit2.38 GB4-bit with slightly higher fidelity
Q4_K_M4-bit2.50 GBBest balance of size and quality ✅ Recommended
Q5_K_S5-bit2.82 GBHigher quality with moderate memory
Q6_K6-bit3.31 GBHigh quality with moderate memory
Q8_08-bit4.28 GBNear full-precision quality, higher memory
Recommendation: Q4_K_M is the best starting point for most users — it offers a strong balance between output quality and memory footprint.

Capabilities

Nexora-Vector-v0.1 is designed to translate textual instructions into structured SVG code. This GGUF release retains all capabilities of the original model while enabling flexible local inference across a wide range of hardware. The model is best suited for:

  • Generating SVG markup for simple vector graphics
  • Producing geometric shapes and basic illustrations
  • Creating lightweight icons and minimal design assets
  • Supporting rapid prototyping in vector-based design workflows
  • Running fully locally with no internet connection required
Tip: The model performs best with concise, clearly scoped prompts focused on simple visual compositions.

Limitations

This is an early-stage beta release. Users should be aware of the following constraints:

  • High hallucination rate — outputs may be invalid or non-renderable SVG
  • Limited generalization — the small training dataset (~1,500 samples) affects output consistency
  • Weak complex scene handling — highly detailed or multi-element prompts may produce poor results
  • Manual correction required — outputs should be validated and post-processed before use
  • Not production-ready — not suitable for safety-critical or automated pipelines
  • Quantization quality trade-off — lower-bit quants (e.g. Q2_K) will show more degradation in output quality

Intended Use

✅ Supported Use Cases

  • Academic and applied research in text-to-vector generation
  • Experimental AI-assisted design systems running locally
  • Educational exploration of structured output generation
  • Lightweight SVG prototyping and ideation with low memory overhead
  • Offline and air-gapped environments requiring fully local inference

❌ Out-of-Scope Use Cases

  • Production-grade or commercial vector asset pipelines
  • High-precision design deliverables without human validation
  • Automated systems where SVG correctness is required without manual review

Architecture & Quantization

This release provides GGUF quantizations of the original Nexora-Vector-v0.1 weights, which are a supervised fine-tune of Qwen3-4B-Instruct.

Fine-tuning MethodSupervised Fine-Tuning (SFT)
Dataset CompositionCurated prompt–SVG pairs
Dataset Size~1,500 samples
Training ObjectiveStructured output generation for SVG formats
Note: The relatively small dataset size may result in instability and limited generalization across diverse prompts. Improved dataset coverage is planned for future versions.

Usage Recommendations

To get the best results from this model:

  1. 1.Keep prompts simple and specific — avoid multi-scene or highly complex compositions
  2. 2.Validate all SVG outputs before rendering or integrating into any pipeline
  3. 3.Post-process outputs to correct syntax or structural issues
  4. 4.Use iterative prompting — refining prompts across multiple turns often yields better results
  5. 5.Expect imperfections — this is a beta model; treat outputs as drafts, not finals
  6. 6.Choose the right quant — use Q4_K_M for the best quality-to-size ratio; only use Q2_K if memory is severely constrained

Evaluation

Nexora-Vector-v0.1 has not yet undergone formal benchmark evaluation. Current assessment is qualitative, based on manual testing of SVG generation tasks.

Planned evaluation metrics for future releases include:

MetricDescription
SVG Validity RatePercentage of outputs that are parseable, valid SVG
Structural CorrectnessAdherence to SVG schema and element hierarchy
Prompt AdherenceAlignment between user intent and generated output
Visual ConsistencyStability of outputs across similar prompts

Risks & Considerations

Developers integrating this model should account for the following risks:

  • Generation of malformed or non-functional SVG code
  • Inconsistent instruction following across prompt variations
  • Unpredictable outputs due to limited training data coverage
  • Quality degradation at lower quantization levels (particularly Q2_K)

Recommendation: Implement downstream validation layers and SVG syntax checking before any rendering or integration.


Future Work

The following improvements are planned for upcoming versions of the Nexora Vector series:

  • [ ] Expanded and more diverse training dataset
  • [ ] Improved SVG syntax correctness and validity rates
  • [ ] Reduced hallucination rates
  • [ ] Enhanced natural language understanding for complex prompts
  • [ ] Support for richer vector compositions and multi-element scenes
  • [ ] Formal benchmark evaluation suite
