InternVL3 5 8B — Hardware Requirements & GPU Compatibility
VisionInternVL3.5-8B is OpenGVLab's 8.5-billion-parameter multimodal model, combining a 0.3-billion-parameter vision encoder with an 8.2-billion-parameter language model. The card says the InternVL3.5 family uses a Cascade Reinforcement Learning framework, offline RL followed by online RL, to improve reasoning and versatility across multimodal, text and agentic tasks, and this checkpoint is the finetune of InternVL3_5-8B-MPO. It is suited to image and document question answering, reasoning over visual content and agent-style tasks. At this size it runs on a single consumer GPU once quantized. The card does not state a context length, so none is given here. It is released under the Apache 2.0 license, permitting commercial and research use. Published in August 2025, it sits in the middle of the InternVL3.5 line, which spans 1B to 38B dense models plus larger mixture-of-experts variants up to 241B total parameters.

- Can I run InternVL3 5 8B on a Mac?
InternVL3 5 8B requires at least 2.6 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 5 8B locally?
Yes — InternVL3 5 8B can run locally on consumer hardware. At Q4_K_M quantization it needs 5.6 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is InternVL3 5 8B?
At Q4_K_M, InternVL3 5 8B can reach ~853 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~116 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 ÷ 5.6 × 0.65 = ~924 tok/s
Estimated speed at Q4_K_M (5.6 GB)
