## AI 摘要

MiniMax H3 在 ThursdAI 对话中被誉为“领先的开源权重开放模型”，直接对标 Seedance、FLUX 和 WAN，并登顶 LMArena 开源视频模型榜首。

A few of the biggest takeaways from our H3 conversation on ThursdAI 🎥

🔓 Open video is reaching the frontier.

The discussion didn't frame H3 as simply "good for an open model." It was compared directly alongside Seedance, FLUX and WAN, with @altryne calling H3 the "leading open weights open model."

And the distinction was immediate: "Open weights, hostable by yourself, finetunable."

⚡ Open weights compound incredibly fast.

Within ~48 hours of launch, the community had already brought LoRA support, Apple Silicon/MLX, ComfyUI quantization and optimizations across new hardware.

That's exactly why we open-weighted H3: putting frontier capabilities in developers' hands means the ecosystem can take the model places we never could alone.

🎭 Omni Reference + character consistency stood out as a major leap.

@blizaine called H3 "so flexible compared to a lot of the previous open-weight models" and said it was "as good as anything I've seen" for recreating a character across environments.

Images, voices, audio and video can all become references - making control and consistency increasingly as important as raw generation quality.

🛠️ Local and hosted workflows can complement each other.

We also discussed Context-IR + Regenerate-2K: generate locally with H3, optimize multimodal context when needed, then regenerate a 768p result at 2K using the original references rather than simply upscaling it.

📈 The broader video capability curve is moving incredibly fast.

@arena perspective summed it up well: "the changes we've seen in the fidelity and the quality and the sound is just unbelievable."

Open models are no longer sitting on a separate curve - they're increasingly competing at the frontier itself.

And a fitting note to end on from our host @altryne:

"Thank you guys for open weighting the models. We expect more." 🙌

We hear you. 🔓
