Black Forest Labs' FLUX Video Upscale sharpens clips to 4K
The pay-per-use API restores 480p clips at 1.5–3x, precise or creative — a real finish for generated video. Plus Tencent's tiny translator hits OpenRouter.

480p in, 4K out
FLUX Video Upscale enlarges clips 1.5–3x (2x by default) to as much as 4K, on sources of at least 480p and under 20 seconds / 50MB. It runs off BFL's /v1/flux-tools/video-upscale-v1 endpoint and bills per megapixel-second of delivered output — you only pay for clips it actually returns.
Precise for identity, Creative for texture
A single creativity dial sets the tradeoff: Precise (0) sharpens without altering anything — right for logos, faces, and on-screen text — while Creative (1) invents fine detail in skin, foliage, and crowds, made for soft AI-generated footage. Reported pricing is $0.07 per megapixel-second in Precise, $0.10 in Creative.
Tencent's 33-language translator is now an API call
Hy-MT2 landed on OpenRouter on Aug 20: the 1.8B runs $0.044/M in and $0.177/M out, the 30B-A3B MoE (3B active) $0.074/$0.295 — both covering 33 languages plus five Chinese dialects, under Apache 2.0. Tencent says the 7B and 30B beat open models like DeepSeek-V4-Pro on translation.
The 1.8B fits on a phone — and it's free to self-host
Skip the API: the 1.8B quantizes to ~440MB (down to 1.25-bit) and runs locally through llama.cpp, vLLM, or SGLang, with Tencent claiming it beats Microsoft's and Doubao's commercial translation APIs. A clean weekend build — fully offline, 33-language translation with no per-call cost.
