InternVL3 78B: Self-Hosting & Deployment Guide
InternVL3 78B is the current generation of the InternVL open-weight vision-language family.
What is InternVL3 78B?
InternVL3 78B is the current generation of the InternVL open-weight vision-language family, published by OpenGVLab with open weights at OpenGVLab/InternVL3-78B. LLM API does not route this model today, so there is no endpoint or code sample for it here. What this page does give you is the self-hosting picture: published weight sizes, the VRAM each quantisation needs and the commands to serve it yourself. Every figure is read from the public repository and refreshed weekly.
How to run InternVL3 78B yourself
Open weights (other), 78.4B parameters. Below: how much memory the weights need at each quantization, which hardware fits them, and the commands to serve it.
InternVL3 78B VRAM requirements
| Precision / quantization | Weights | Figure | Source |
|---|---|---|---|
| BF16 (full precision) | 156.8 GB | Estimate | 78.4B params × 2 bytes |
| FP8 | 86.6 GB | File size | brandonbeiler/InternVL3-78B-FP8-Dynamic |
| AWQ 4-bit | 52.9 GB | File size | OpenGVLab/InternVL3-78B-AWQ |
| MLX 4-bit | 52.1 GB | File size | mlx-community/InternVL3-78B-4bit |
| GGUF Q4_K_M | 47.4 GB | File size | unsloth/InternVL3-78B-Instruct-GGUF |
| GGUF Q2_K | 29.8 GB | File size | unsloth/InternVL3-78B-Instruct-GGUF |
File size = actual download size on Hugging Face. Estimate = parameter count × bytes per weight. Weights only — the KV cache for long contexts needs extra memory; the fit tables below add 15% headroom as a rule of thumb.
