| # FlashVSR — hosted API access |
|
|
| **FlashVSR** is a real-time, diffusion-based streaming **video super-resolution** model |
| (CVPR 2026). This repository is **not the model weights** — it is a documentation page for |
| running FlashVSR through a hosted API on **[apimodels.app](https://apimodels.app)**, a |
| multi-model API gateway where one key and one OpenAI-compatible endpoint reach 110+ image, |
| video, audio and language models. |
|
|
| - Original model & weights: **[JunhaoZhuang/FlashVSR](https://huggingface.co/JunhaoZhuang/FlashVSR)** |
| - Authors: Junhao Zhuang, Shi Guo, Xin Cai, Xiaohui Li, Yihao Liu, Chun Yuan, Tianfan Xue |
| - License: Apache-2.0 (this page follows the upstream license) |
|
|
| This page is an independent, hosted-API integration. It is **not affiliated with or endorsed |
| by the authors** and does not redistribute their weights. All credit for the model is theirs. |
|
|
| ## What it does |
|
|
| Turn a low-resolution clip into a sharper 720p / 1080p / 2K / 4K video. FlashVSR is a |
| one-step streaming framework, so it is fast enough for real-time use. |
|
|
|  |
|
|
| *Same frame and region: a 480p source clip (left) vs the FlashVSR result at 1080p (right), |
| produced through the apimodels.app API. No other edits.* |
|
|
| ## Use it via API |
|
|
| No GPU or setup on your side — call the hosted endpoint on apimodels.app. Get a key at |
| https://apimodels.app, then: |
|
|
| ```bash |
| # 1) upload the clip -> get a public URL |
| curl -X POST https://api.apimodels.app/v1/files \ |
| -H "Authorization: Bearer YOUR_API_KEY" \ |
| -F "file=@input.mp4;type=video/mp4" |
| # -> { "data": { "publicUrl": "https://r2.apimodels.app/uploads/.../input.mp4" } } |
| |
| # 2) create the upscale task (resolution: 720p | 1080p | 2k | 4k) |
| curl -X POST https://api.apimodels.app/v1/video/generations \ |
| -H "Authorization: Bearer YOUR_API_KEY" \ |
| -H "Content-Type: application/json" \ |
| -d '{ "model": "flashvsr", "video": "<publicUrl>", "resolution": "1080p" }' |
| # -> { "data": { "taskId": "..." } } |
| |
| # 3) poll until state == "completed" |
| curl "https://api.apimodels.app/v1/video/generations?task_id=TASK_ID" \ |
| -H "Authorization: Bearer YOUR_API_KEY" |
| # -> { "data": { "state": "completed", "resultUrls": ["https://..."] } } |
| ``` |
|
|
| Python (OpenAI-style base URL not needed — plain HTTP): |
|
|
| ```python |
| import requests |
| BASE, KEY = "https://api.apimodels.app", "YOUR_API_KEY" |
| H = {"Authorization": f"Bearer {KEY}"} |
| |
| pub = requests.post(f"{BASE}/v1/files", headers=H, |
| files={"file": ("input.mp4", open("input.mp4", "rb"), "video/mp4")} |
| ).json()["data"]["publicUrl"] |
| task = requests.post(f"{BASE}/v1/video/generations", headers=H, |
| json={"model": "flashvsr", "video": pub, "resolution": "1080p"} |
| ).json()["data"]["taskId"] |
| # then GET {BASE}/v1/video/generations?task_id=task until state == "completed" |
| ``` |
|
|
| ## Pricing |
|
|
| Billed per second of **input** video length (not output). Failed jobs are not charged. |
| Result files are kept for 7 days. |
|
