Apollo-VL-Edge-3B — GGUF Quantizations

Intelligence isn't about scale. It's about precision.

Apollo-VL-Edge-3B is an efficient Vision-Language Model (VLM) developed by Pluto AI Labs, designed for practical multimodal inference on consumer hardware.

This repository provides the official GGUF quantizations of Apollo-VL-Edge-3B for local inference with llama.cpp and compatible runtimes.

Overview

Apollo-VL-Edge-3B is built upon the foundation of Qwen2.5-VL-3B-Instruct, bringing multimodal understanding, visual reasoning, document understanding, and OCR capabilities to hardware with significantly lower memory requirements.

The GGUF release is optimized for:

• Local and offline inference
• CPU inference
• Low-VRAM GPUs
• Consumer laptops and desktops
• Apple Silicon devices
• Edge AI deployments
• llama.cpp
• LM Studio
• Ollama-compatible workflows

Model Highlights

• 3B parameter-class VLM
• Multimodal image + text understanding
• Visual question answering
• Chart understanding
• Science diagram reasoning
• Document understanding
• OCR and text extraction
• Visual reasoning
• Local inference
• GGUF quantization support
• Designed for edge and consumer hardware

Note: Apollo-VL-Edge-3B GGUF models require the corresponding multimodal projector (mmproj) file for image understanding.

Provided Quantizations

Multimodal Projector

To use the vision capabilities, you must load:

mmproj-Apollo-VL-Edge-3B-f16.gguf

alongside your selected GGUF model.

The mmproj file handles the connection between the visual encoder and language model.

---

Benchmark Performance

Apollo-VL-Edge-3B was evaluated across visual reasoning, chart understanding, and document OCR benchmarks.

Evaluation Results

Quantization note: Lower-bit quantizations such as Q4_K_M may introduce some degradation on complex visual reasoning tasks. For maximum fidelity, use F16 or Q8_0.

---

Hardware Recommendations

Actual memory requirements may vary depending on context length, runtime configuration, GPU offloading, and system RAM.

---

Usage

llama.cpp

Apollo-VL-Edge-3B can be run locally using llama.cpp with both the main GGUF model and multimodal projector.

CLI Inference

./llama-cli \
  -m Apollo-VL-Edge-3B-Q4_K_M.gguf \
  --mmproj mmproj-Apollo-VL-Edge-3B-f16.gguf \
  -p "Describe this image in detail." \
  --image "path/to/your/image.png"

Replace the model filename with your preferred quantization.

---

llama-server

Apollo-VL-Edge-3B can also be served through the OpenAI-compatible llama-server API.

./llama-server \
  -m Apollo-VL-Edge-3B-Q4_K_M.gguf \
  --mmproj mmproj-Apollo-VL-Edge-3B-f16.gguf \
  --host 0.0.0.0 \
  --port 8080

The server can then be accessed through compatible OpenAI API clients.

---

LM Studio

Apollo-VL-Edge-3B can be used locally through LM Studio.

Steps

1. Open LM Studio.
2. Search for Apollo-VL-Edge-3B-GGUF.
3. Download your preferred quantization.
4. Download the corresponding mmproj file.
5. Load the GGUF model.
6. Attach an image.
7. Start the conversation.

For the best balance between performance and quality, Q4_K_M or Q5_K_M is recommended for typical consumer hardware.

---

Ollama

If your Ollama workflow supports the required multimodal GGUF configuration, Apollo-VL-Edge-3B can be integrated into a local Ollama deployment.

The recommended configuration is to pair:

Apollo-VL-Edge-3B-Q4_K_M.gguf

with:

mmproj-Apollo-VL-Edge-3B-f16.gguf

Refer to the runtime-specific documentation for the exact multimodal configuration required by your Ollama version.

---

Multimodal Projector

The multimodal projector is required for visual inference.

mmproj-Apollo-VL-Edge-3B-f16.gguf

Required Files

A typical deployment should contain:

Apollo-VL-Edge-3B-GGUF/
├── Apollo-VL-Edge-3B-Q4_K_M.gguf
├── mmproj-Apollo-VL-Edge-3B-f16.gguf
└── README.md

You can replace Q4_K_M with another available quantization.

---

Model Architecture

Apollo-VL-Edge-3B is based on the Qwen2.5-VL-3B-Instruct architecture and is designed for multimodal visual-language workloads.

The system combines:

Image
  ↓
Vision Encoder
  ↓
Multimodal Projector
  ↓
Language Model
  ↓
Text Response

The GGUF distribution separates the language-model weights from the multimodal projector so that compatible inference engines can efficiently load and execute the complete VLM.

---

Limitations

Apollo-VL-Edge-3B is intended for research, experimentation, and local AI applications.

Potential limitations include:

• Visual hallucinations
• OCR errors on low-quality images
• Reduced accuracy on highly complex diagrams
• Sensitivity to image resolution
• Reduced reasoning performance under aggressive quantization
• Potential inaccuracies in numerical chart interpretation
• Performance differences across inference runtimes

Model outputs should be independently verified for high-stakes applications.

---

Recommended Quantization

For most users:

Q4_K_M — Best overall edge deployment choice

For higher-quality inference:

Q5_K_M / Q6_K

For maximum fidelity:

Q8_0 / F16
