InternVL3 1B — Hardware Requirements & GPU Compatibility
Vision
InternVL3-1B is OpenGVLab's smallest vision-language model in the InternVL3 series, combining an InternViT-300M-448px-V2.5 vision encoder with a Qwen2.5-0.5B language backbone through an MLP projector. Unlike earlier InternVL generations, it uses Native Multimodal Pre-Training, interleaving image-text and video-text data with text-only corpora in a single pretraining stage rather than adapting a finished text model, and adds Variable Visual Position Encoding for better long-context handling. The series extends its capabilities to tool use, GUI agents, industrial image analysis, and 3D vision perception. At under 1 billion parameters, it is small enough to run on a modest consumer GPU or even a CPU. It is released under the Apache 2.0 license, permitting unrestricted commercial and research use. It was published in April 2025, as the smallest member of a family that scales up to InternVL3-78B.

Frequently Asked Questions
- How much VRAM does InternVL3 1B need?
InternVL3 1B requires 0.6 GB of VRAM at Q4_K_M, or 2.1 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 938M × 4.8 bits ÷ 8 = 0.6 GB
VRAM usage by quantization
Q4_K_M0.6 GB- What's the best quantization for InternVL3 1B?
For InternVL3 1B, Q4_K_M (0.6 GB) offers the best balance of quality and VRAM usage. Q5_K_S (0.7 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 0.3 GB.

- Can I run InternVL3 1B on a Mac?
InternVL3 1B requires at least 0.3 GB at IQ2_XXS, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run InternVL3 1B locally?
Yes — InternVL3 1B can run locally on consumer hardware. At Q4_K_M quantization it needs 0.6 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is InternVL3 1B?
At Q4_K_M, InternVL3 1B can reach ~7742 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~1057 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 0.6 × 0.65 = ~8387 tok/s
Estimated speed at Q4_K_M (0.6 GB)
~8387 tok/s~1057 tok/s~8387 tok/s~7742 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of InternVL3 1B?
