A vibrant tropical fish swimming gracefully among colorful coral reefs in a clear, turquoise ocean. The fish has bright blue 
and yellow scales with a small, distinctive orange spot on its side, its fins moving fluidly. The coral reefs are alive with 
a variety of marine life, including small schools of colorful fish and sea turtles gliding by. The water is crystal clear, 
allowing for a view of the sandy ocean floor below. The reef itself is adorned with a mix of hard and soft corals in shades 
of red, orange, and green. The photo captures the fish from a slightly elevated angle, emphasizing its lively movements and 
the vivid colors of its surroundings. A close-up shot with dynamic movement.

A towering emerald wave surges forward, its crest curling with raw power and energy. Sunlight glints off the translucent water, 
illuminating the intricate textures and deep green hues within the wave’s body. A thick spray erupts from the breaking crest, 
casting a misty veil that dances above the churning surface. As the perspective widens, the immense scale of the wave becomes 
apparent, revealing the restless expanse of the ocean stretching beyond. The scene captures the ocean’s untamed beauty and 
relentless force, with every droplet and ripple shimmering in the light. The dynamic motion and vivid colors evoke both awe and 
respect for nature’s might.

A bright yellow Lamborghini Huracn Tecnica speeds along a curving mountain road, surrounded by lush green trees 
under a partly cloudy sky. The car&#x27;s sleek design and vibrant color stand out against the natural backdrop, 
emphasizing its dynamic movement. The road curves gently, with a guardrail visible on one side, adding depth to 
the scene. The motion blur captures the sense of speed and energy, creating a thrilling and exhilarating atmosphere. 
A front-facing shot from a slightly elevated angle, highlighting the car&#x27;s aggressive stance and the surrounding greenery.

A vibrant tropical fish swimming gracefully among colorful coral reefs in a clear, turquoise ocean. The fish has bright blue 
and yellow scales with a small, distinctive orange spot on its side, its fins moving fluidly. The coral reefs are alive with 
a variety of marine life, including small schools of colorful fish and sea turtles gliding by. The water is crystal clear, 
allowing for a view of the sandy ocean floor below. The reef itself is adorned with a mix of hard and soft corals in shades 
of red, orange, and green. The photo captures the fish from a slightly elevated angle, emphasizing its lively movements and 
the vivid colors of its surroundings. A close-up shot with dynamic movement.

A towering emerald wave surges forward, its crest curling with raw power and energy. Sunlight glints off the translucent water, 
illuminating the intricate textures and deep green hues within the wave’s body. A thick spray erupts from the breaking crest, 
casting a misty veil that dances above the churning surface. As the perspective widens, the immense scale of the wave becomes 
apparent, revealing the restless expanse of the ocean stretching beyond. The scene captures the ocean’s untamed beauty and 
relentless force, with every droplet and ripple shimmering in the light. The dynamic motion and vivid colors evoke both awe and 
respect for nature’s might.

A bright yellow Lamborghini Huracn Tecnica speeds along a curving mountain road, surrounded by lush green trees 
under a partly cloudy sky. The car&#x27;s sleek design and vibrant color stand out against the natural backdrop, 
emphasizing its dynamic movement. The road curves gently, with a guardrail visible on one side, adding depth to 
the scene. The motion blur captures the sense of speed and energy, creating a thrilling and exhilarating atmosphere. 
A front-facing shot from a slightly elevated angle, highlighting the car&#x27;s aggressive stance and the surrounding greenery.

A vibrant tropical fish swimming gracefully among colorful coral reefs in a clear, turquoise ocean. The fish has bright blue 
and yellow scales with a small, distinctive orange spot on its side, its fins moving fluidly. The coral reefs are alive with 
a variety of marine life, including small schools of colorful fish and sea turtles gliding by. The water is crystal clear, 
allowing for a view of the sandy ocean floor below. The reef itself is adorned with a mix of hard and soft corals in shades 
of red, orange, and green. The photo captures the fish from a slightly elevated angle, emphasizing its lively movements and 
the vivid colors of its surroundings. A close-up shot with dynamic movement.

A towering emerald wave surges forward, its crest curling with raw power and energy. Sunlight glints off the translucent water, 
illuminating the intricate textures and deep green hues within the wave’s body. A thick spray erupts from the breaking crest, 
casting a misty veil that dances above the churning surface. As the perspective widens, the immense scale of the wave becomes 
apparent, revealing the restless expanse of the ocean stretching beyond. The scene captures the ocean’s untamed beauty and 
relentless force, with every droplet and ripple shimmering in the light. The dynamic motion and vivid colors evoke both awe and 
respect for nature’s might.

Specifically, Helios is a 14B autoregressive diffusion model with a unified input representation that natively supports T2V, I2V, and V2V tasks. To mitigate drifting in long-video generation, we characterize its typical failure modes and propose simple yet effective training strategies that explicitly simulate drifting during training, while eliminating repetitive motion at its source. For efficiency, we heavily compress the historical and noisy context and reduce the number of sampling steps, yielding computational costs comparable to—or lower than—those of 1.3B video generative models. Moreover, we introduce infrastructure-level optimizations that accelerate both inference and training while reducing memory consumption. Extensive experiments demonstrate that Helios consistently outperforms prior methods on both short- and long-video generation.
