看群核科技的创业经历还挺传奇，三位创始人均毕业于顶尖高校（浙大、清华、伊利诺伊大学），曾在英伟达、谷歌、微软等企业任职，精通计算机图形学、并行计算、GPU编程等领域。黄晓煌深度参与英伟达CUDA研发，朱皓擅长底层图形算法，陈航具备全栈开发能力。这样一个即使今天看起来都是最顶级豪华配的创业团队，创业方向应该是更高级的图形图像、高性能计算之类。但一开始选择了家装O2O看上去并不是高壁垒的领域、背后还是有很多故事的。 群核科技成立之初，就是一家“拿着锤子找钉子”的公司，黄晓煌手握着当时最先进的云端GPU物理渲染仿真技术回国创业，到处找应用场景。十五年前、很多投资人可能都没听过GPU，群核是靠讲一个线上虚拟家居社区（类似 Houzz，这家公司当年估值达到了 40 亿美金）才融到钱。又摸索一翻，最后是在钱多的要死的地产行业找到了客户，推出了空间设计软件酷家乐。 从家装O2O到设计师SaaS，群核的这些产品不仅让公司赚到钱，活下来。还通过家居、建筑、工业等场景让群核科技积累了大量实际场景应用的3D空间高质量数据。从18年开始，群核又开始回归最早创业的初心。 2018年，群核科技就和帝国理工、南加州大学一起共同发布了全球最大的室内场景认知深度学习数据集，包含了 1.3 亿空间数据。2015年12月，群核又联合浙江大学开源了 SAGE-3D 数据集。这是业内首个基于 3D 高斯 VLE（视觉语言导航）的具身学习数据集。 高质量数据+算法+自建大规模 GPU集群的威力逐渐显现。 2025 年，群核科技发布了业内首个 3D 场景生成的空间大模型，包含空间语言模型SpatialLM和空间生成模型SpatialGen。这是全球第一个真正专注于“空间智能”的行业大模型，将AI从“文本语言”向“空间语言”进化。 自此开始引领空间智能。 2023年，群核科技把整个战略重心转向了空间智能。 黄晓煌说：“过去公司以为增长核心是产品，但现在越来越意识到， 真正决定上限的是产品下面那层算法和模型能力。" 如果这个判断成立，群核未来卖的就不只是一个设计软件，而是一种可被反复调用的空间理解与生成能力。收费方式也会从按席位、按订阅收费，变成按token、按调用量收费。 现在回看群核的创业路径，是一种与主流创业逻辑完全相反的路径。 大多数人是先看到市场需求（钉子），再去打造对应的工具（锤子）。 而黄晓煌恰恰相反： 他先花了14年时间，把一把"GPU实时渲染+3D空间数据"的锤子磨得无比锋利， 然后在不同的时代，用这同一把锤子去敲不同的钉子。 从家装O2O到设计师SaaS， 再到AI研究和空间智能， 群核科技四次转身，锤子从未更换，钉子却换了四颗。 他把这套方法，形象地称为"拿着锤子找钉子"。业务场景在变、但是内核越来越坚实。 早上港股开盘，20左右追了一些群核。个人角度，市场大概率会给这样的继续想象力的的公司买单。

《吻我之前，先把灯关了》 "Turn Off the Lights Before You Kiss Me" 据专家研究分析，恐怖片和爱情动作片，好莱坞惊险片都能刺激大脑分泌多巴胺，我现在把它们都放在一起了，那是不是应该双倍快乐来了。 According to expert research and analysis, horror movies, romantic action films, and Hollywood thrillers can all stimulate the brain to release dopamine. Since I’ve combined them all together, does that mean I’m in for a double dose of happiness? grok imagine prompt: "Turn Off the Lights Before You Kiss Me" 15 seconds, 9:16 vertical format, first-person perspective, recorded on a smartphone, single continuous take. [Realistic Cinematography] The footage is captured entirely by the rear-facing camera of the smartphone held by the male protagonist; no other cameras are involved. The male protagonist holds the phone in his right hand, using the primary (1×) rear lens—providing a field of view equivalent to approximately 26mm—at 1080p resolution and 30fps. The device is positioned between his chest and chin (at a height of roughly 1.45 meters), aimed toward a woman standing in the bathroom doorway. His left hand occasionally enters the frame to operate the light switch. The smartphone itself—its body, back panel, camera module, screen, or flash—is never visible in the shot. Only the light cast by the phone onto the subject, her clothing, and the walls can be seen. There are no mirrors present; this is not a mirror-based selfie. The footage retains the raw, authentic texture of smartphone video—no beauty filters, color grading, or cinematic effects. Skin details such as pores, fine beads of sweat, stray hairs, and natural skin-tone variations are visible. There is slight digital noise in the shadows, and brief motion blur occurs during rapid hand movements or moments of physical instability. Subtle camera shake stems from the holder’s breathing and wrist movements. Changes in proximity are achieved through actual physical steps or the subject pulling the holder closer; there is no digital zooming, automated panning, reverse-angle cutting, or slow motion. The focus remains primarily on the woman’s face, with only momentary hesitation when the distance shifts abruptly—there is no persistent out-of-focus effect. [Characters and Attire] The woman in the doorway (@80130fc6-f744-4f61-9faf-f630a1eb8638) is 28 years old. Her appearance—including her black hair styled in an updo, purple floral hair accessory, earrings, long-sleeved Japanese-style (wafuku) garment in purple (@d7529a1b-8cdb-41e5-816e-c59aa4051803), and dark-colored *obi* (sash)—is consistent with the video uploaded by the user. Her clothing remains intact; the neckline stays in place, and she does not scratch her own chest or tug at her garments. Leaning slightly against the doorframe, she keeps her shoulders relaxed and lowered, her neck elongated, and her legs positioned one in front of the other—creating a natural, subtle S-curve in her posture. She gazes toward the male protagonist with half-lidded eyes and a faint, inviting smile, as if beckoning him closer. From the very beginning, her right hand holds a small pinch of fabric from the male protagonist’s left cuff. This point of contact—her right hand gripping his left cuff—is situated in the lower-left portion of the frame and must remain visible. Because she is only holding the fabric rather than clamping down on his wrist, he retains the freedom to lift his left hand and operate the light switch. Initially, her left hand is concealed between her body and the doorframe. The grayish-white fingers that appear later belong to this same hand; the creature possesses only two hands throughout the entire sequence. The real girlfriend is located in the hallway behind the male protagonist. She is present only as a voice calling out from off-screen; she is never shown on camera, and no second female face appears. 【Environment and Space】 The scene takes place at the entrance to a bathroom in an old apartment building late at night. The setting—featuring aged off-white tiles, a worn wooden doorframe, a standard wall-mounted light switch, and a towel hanging inside the bathroom—conveys the lived-in, weathered feel of an old residence, rather than a ruin. The woman is positioned slightly to the right of the frame’s center, with the open bathroom door behind her. The light switch is located on the wall to the left, approximately thirty centimeters from the male protagonist’s left hand. It is visible from the start and does not suddenly appear later. Behind the male protagonist lies a hallway. The bathroom door remains open inward; the camera angle stays consistent throughout, the door does not move on its own, and the room’s layout remains unchanged. At the start, the woman’s face is about sixty centimeters from the camera. After she gives a gentle tug on his cuff, the male protagonist shifts forward slightly, reducing the distance to approximately forty-five centimeters. The distance closes further only during the final dragging motion. 【Ambient Lighting】 At the beginning, a warm-white overhead light in the bathroom is on, illuminating the woman’s head, shoulders, and the doorway, while the hallway remains dim. The LED flash on the back of the smartphone is illuminated from the very first frame; it remains on and in the same position throughout the entire 15-second duration. Up close, the face is illuminated by the harsh, direct light of a standard mobile phone; small shadows form beside the nose and under the chin, and there are localized highlights on the fabric of the clothing—no artificial "beauty" fill lighting is applied. The only light the male lead turns off is the overhead bathroom light. Once the overhead light is extinguished, the bathroom background remains dim and does not brighten on its own. The phone’s light continues to illuminate her face and the hand gripping the sleeve cuff. The camera’s auto-exposure adjusts only slightly, failing to brighten the dark bathroom to a daylight-like state. When the "mask" (the outer layer of the face) is peeled back, it is illuminated by the same mobile phone light as the rest of the face. The space deep behind the shell remains dark, and the exposed eyeball shows only natural, subtle reflections—it does not emit its own light. [The "False Face" Effect] The horror stems from a thin, pliable, artificial layer being peeled back from within—it is not a case of natural skin being torn or a mouth stretching into an impossible, elongated shape. A grayish-white hand—with only two or three fingertips visible—emerges from the corner of her mouth, hooks onto the lower edge of the "mask," and peels half of the face upward and to the side. The "mask" has a distinct thickness and flexibility; the cheek and part of the area beside the nose fold back, rather than stretching into long, tubular, funnel-like, or tongue-like shapes. Behind the peeled-back section lies a deep, dark cavity containing a normal-sized human eye, which turns to look directly at the camera. The other half of the woman’s face remains intact, establishing the premise that there is an artificial layer on the outside, with something else concealed beneath it. There is no blood, gore, exposed muscle, black ooze, or liquid-like melting effect. The grayish hand does not reach in from off-screen; its fingertips must first emerge from within the corner of the mouth. [Strict 15-Second Timeline] 0–4 Seconds | Gripping the sleeve, an invitation to draw closer. The woman leans sideways against the doorframe, looking first into the male lead’s eyes, then glancing briefly toward the light switch on the left. With her right hand, she grasps the male lead’s left sleeve cuff—positioned at the bottom-left of the frame—and gives it a gentle tug toward herself. The fabric of the cuff pulls taut, prompting the male lead to take a small step forward; the camera moves in tandem with his approach. She lifts her chin slightly and says in a low voice: “The lights are too bright.” Her tone is intimate, with a suppressed smile playing at the corners of her mouth. There is no sign of a monstrous visage, nor does she glance toward her own mouth beforehand. Her right hand continues to hold the same spot on his sleeve; she does not shift her grip to his lapel. 4–7 seconds | Flipping the switch; the background darkens The male protagonist reaches out with his left hand toward a light switch already visible on the left side of the frame. She keeps her grip on his left sleeve, causing her right arm to extend naturally as he moves—she neither lets go nor suffers any "clipping" (graphical glitching). His fingertips press the switch, producing a distinct *click*. The bathroom overhead light goes out, and the tiles, towels, and the space behind the woman grow noticeably darker. Her face remains illuminated by the fill light from a mobile phone. The male protagonist’s left hand pulls away from the switch and returns to the space between them. The camera tilts slightly with the movement, then steadies. 7–9 seconds | A warning from behind From about two meters behind the camera, the man’s actual girlfriend calls out urgently, in an identical tone: “Don’t turn off the light!” The woman in front of him says nothing; her lip movements do not correspond to this warning. As the male protagonist begins to turn, the camera shifts slightly to the side—but the hand gripping his sleeve suddenly tightens, holding him in place. Her smile vanishes. Her eyes glance past the camera toward the space behind the man, then return to the lens. Her knuckles whiten as she grips the sleeve, causing deeper creases to form in the fabric. 9–12 seconds | Half of her face is peeled back from within Two or three grayish-white fingertips emerge from the inner corner of her mouth. The fingertips hook onto the lower edge of the "shell" of her face, slowly peeling it upward and outward. The corner of her mouth and her cheek—forming a single, thin, pliable layer—fold back together; the lips do not stretch or elongate independently. Half of the artificial face is lifted away, revealing an eye in the darkness beneath that shifts to look directly at the camera. The intact half of her face remains visible alongside the eye revealed from within. For a brief moment, the camera steadies, allowing at least half a second to take in the details: Fingers emerge from within the face; the "shell" of the face begins to fold back, revealing another eye underneath. The woman’s right hand maintains a firm grip on the man’s left cuff—she cannot let go, even as she peels back the face. The only sounds are the dry, grating friction of the mask and the man’s sudden, sharp intake of breath. 12–15 seconds | The grip shifts into a forceful tug. The man immediately grabs the woman’s right wrist—the one holding his cuff—and tries to pry it away. The point of contact is clearly visible; he does not reach for the grey, peeling fingers. The creature’s right arm suddenly retracts toward the bathroom, yanking the cuff hard. The sequence must be clear: The cuff goes taut → the man’s left arm is pulled straight → his body stumbles forward → the camera (held in his right hand) is dragged closer. The camera moves from about 45 centimeters away to roughly 15 centimeters, accompanied by a sudden dip and tilt—this is not a smooth, controlled zoom. The partially peeled-back face, the unblinking eye beneath, and the greyish-white fingers now dominate the frame. The other half of the face remains "normal," preserving its original appearance. In the final half-second, the man collides with the wooden doorframe, producing a dull thud. The camera jerks to the side; the edge of the facial shell sweeps across the lens, partially obscuring the view. The recording ends abruptly while the struggle is still underway. No fade to black, no additional dialogue, and no new creatures appear. [Ambient Audio] Captured via a mobile phone microphone: close-range speech, the friction of fabric at the cuff, the sound of a light switch, the hum of a bathroom exhaust fan, the distant ambient noise of the city, heavy breathing, and the final impact against the doorframe. The exhaust fan continues to run independently; it does not stop when the overhead light is switched off. The background sounds maintain a sense of spatial distance—they are not suddenly muted for the sake of a "jump scare." The opening line, "The light is too bright," comes from the woman in front of him. The mid-sequence line, "Don't turn off the light," clearly originates from behind the man; the woman in front does not move her lips. There is no further dialogue—no sinister laughter, voice-over narration, heartbeat sound effects, or pre-recorded horror audio cues. [Mandatory Continuity] The only camera is the mobile phone through which the audience is viewing the scene; the phone itself is never visible within the frame, nor is there any additional camera operator. The male protagonist holds the phone in his right hand; he uses his left hand to flip the light switch, then immediately grabs the monster’s right wrist. The monster’s right hand remains firmly gripping the same spot on the male protagonist’s left cuff; its left hand lifts a portion of the "false face" from underneath. Do not generate a third hand, swap left and right hands, or have the monster’s hand shift its grip from the cuff to the female protagonist’s own clothing. Once the bathroom light is turned off, it remains off; the mobile phone’s light source (fill light) stays on. The positions of the door and the light switch remain fixed. Changes in distance must be achieved through physical movement (stepping or dragging); do not use digital zoom. The "false face" should be lifted, not stretched like rubber; do not generate long tongues, tubular mouths, an elongated jaw, or a melting face.
