Qwen@Alibaba_QwenAI 评分7575Qwen:Blog Retrieval精选AI 评分8989 Qwen3.8-Max 发布:开源最强编码与协作模型,2.4T 参数
Qwen 正式发布 Qwen3.8-Max,这是 Qwen 家族迄今最强的模型,拥有 2.4T 参数(95B 激活),并首次开源 Qwen-Max 级权重,开放权重将于下周发布。
推荐理由:首次将 Max 级模型权重开源,为开源社区提供比肩闭源旗舰的能力,但实际效果需待下周权重放出后由社区验证。

MiniMax (official)@MiniMax_AIAI 评分4848引用𝔹𝕃𝕍ℂ𝕂𝕃!𝔾ℍ𝕋@BLVCKLIGHTaiI’m seeing way better videos coming from H3 than 2.5 on the timeline. And more of them. I think cost is a big part of it, plus the speed of inference, and custom audio uploads working as intended. My thesis holds still that at a certain point unless you are actually fixing the pressure points creatives have with your tools, cost and speed are going to win. Unlimited generations are NOT a pipe team. It all comes down to hourly costs divided by users. At some point if you can scale you’ll run at a surplus and can run unlimited.
Aravind Srinivas@AravSrinivasAI 评分5858引用Chubby♨️@kimmonismusDeepSeek V4-Flash isn’t just cheaper per token. It reportedly completes the same benchmark tasks as Fable 5 at 105× lower total cost, according to @ArtificialAnlys ! That's precisely why the Flash release is, for me, the DeepSeek 2.0 moment. It will cause a huge stir.

MiniMax (official)@MiniMax_AIAI 评分6060引用MTS@MTSliveSITUATION EXPLAINED: MiniMax released H3 with open weights, and it's already #1 in video editing. • Priced at $7.80 per minute of 2K video, against Seedance 2.0 at $22.45 and Kling 3.0 at $20.16 • It ranks #1 on Artificial Analysis for video editing, #2 for text-to-video behind Gemini Omni Flash, and #3 for image-to-video • H3 takes text, images, video, and audio in a single context and generates 5-15 second clips at native 2K, 24fps, with native stereo audio • MiniMax is releasing the weights under its Community License within days, which would make it the strongest open-weights video model by a wide margin • It launched the same week ByteDance rolled out Seedance 2.5, which now generates 30-second 4K video from a single prompt • Seedance 2.5's face consistency across a full 30 seconds is the visible jump, earlier models drifted into a different face partway through • Voices are still the obvious tell, the video reads as real long before the audio does • Smaller labs building purpose-built video models are now beating frontier labs at this specific task @theojaffee: "This is gonna be one of the biggest examples of things that people are gonna do with these models, historical simulations, basically. Nostalgia videos for zoomers."
