Abstract

We introduce SANA-WM, an efficient 2.6B-parameter open-source world model natively trained for one-minute generation, synthesizing high-fidelity, 720p, minute-scale videos with precise camera control. SANA-WM achieves visual quality comparable to large-scale industrial baselines such as LingBot-World and HY-WorldPlay, while significantly improving efficiency. Four core designs drive our architecture: (1) Hybrid Linear Attention combines frame-wise Gated DeltaNet with softmax attention for memory-efficient long-context modeling; (2) Dual-Branch Camera Control ensures precise 6-DoF trajectory adherence; (3) Two-Stage Generation Pipeline applies a long-video refiner to stage-1 outputs, improving quality and consistency across sequences; and (4) Robust Annotation Pipeline extracts accurate metric-scale 6-DoF camera poses from public videos to yield high-quality, spatiotemporally consistent action labels. Driven by these designs, SANA-WM uses only ~213K public video clips with metric-scale pose supervision, completes training in 15 days on 64 H100s, and generates each 60-second clip on a single GPU; its distilled variant runs on a single RTX 5090 with NVFP4 quantization to denoise a 60s 720p clip in 34s. On our one-minute world-model benchmark, SANA-WM demonstrates stronger action-following accuracy than prior open-source baselines and achieves comparable visual quality at 36x higher throughput.

Prompt A first-person view from a strictly stationary observation point on the snowy shore of a frozen alpine lake at twilight. The spatial layout opens across a broad sheet of ice toward a solitary red wooden door centered far out on the lake, with a trail of footprints leading across the frozen surface and thin cracks radiating back toward the shore. Snow-laden pine trees frame both sides, while distant mountain ridges reflect across the dark, glassy ice. Materials feel crisp and tactile: packed snowbanks, frosted rocks, scratched translucent ice, powder-coated branches, and painted wood glowing at the base of the door. Lavender-blue dusk light blends with warm golden light leaking from beneath the door, creating a quiet, surreal mystery. There is no dynamic camera movement and no action by the unseen observer; the world moves independently as snowflakes fall, clouds drift, pine boughs tremble, and reflections shimmer faintly across the ice.

Prompt

Prompt A first-person view from a strictly stationary observation point inside a vast jungle canyon. The spatial layout forms a deep natural corridor between steep vine-covered cliffs, opening toward a massive waterfall that veils an ancient stone temple barely visible behind the falling water. A small folded paper airplane occupies the foreground as part of the scene, framed by colorful birds and drifting leaves. Materials feel vivid and layered: crisp paper folds, wet stone walls, tangled vines, glossy foliage, suspended droplets, and weathered carved masonry softened by spray. Bright daylight filters through the canyon, creating mist, rainbow light, and a whimsical adventure atmosphere. There is no dynamic camera movement and no action by the unseen observer; the world moves independently as the waterfall crashes, mist billows, birds flap across the canyon, leaves tumble, droplets sparkle, and the paper plane quivers in the air currents.

Prompt

Prompt A first-person view from a strictly stationary observation point inside a vast abandoned shopping mall atrium reclaimed by vegetation. Multi-level balconies, broken storefronts, rusted railings, escalators, and a cracked glass roof frame a deep central hall, where a quadcopter hovers above a debris-strewn floor and a red signal glows on the far balcony. The space is textured with peeling concrete, stained walls, shattered skylight panels, hanging vines, moss-covered steps, torn banners, puddles, and scattered rubble. Sunbeams pour through the damaged roof, illuminating dust and humid greenery with a warm, post-collapse atmosphere. The observer's perspective remains fixed, with no dynamic camera movement and no actions taken by the person recording. Autonomous motion animates the environment: drone rotors spin, birds cross the atrium, vines sway gently, water drips into puddles, dust motes drift through the light, and the red beacon pulses faintly.

Prompt

Prompt A first-person view from a strictly stationary observation point on an abandoned underground subway platform. The spatial layout extends along a wet platform and parallel train tracks into a deep tunnel, where a faint red glow pulses at the vanishing point; a slightly open maintenance door, discarded suitcase, old newspaper, tiled walls, and concrete support columns define the side spaces. Materials are grimy and tactile: cracked concrete, stained ceramic tile, rusted rail metal, puddled floor seams, dangling black cables, peeling paint, and damp soot on the ceiling. Flickering fluorescent fixtures cast weak reflections across the platform, creating a tense urban mystery atmosphere. There is no dynamic camera movement and no action taken by the unseen observer; the world moves independently as steam drifts from vents, ceiling lights stutter, the red tunnel glow throbs softly, water trembles in shallow puddles, and loose papers flutter faintly in the stale air.

Prompt A first-person view from a strictly stationary observation point on a deserted tropical beach at sunrise. The spatial layout stretches from the foamy shoreline on the left across wet reflective sand toward a dense wall of jungle and leaning palms on the right, with a long mysterious drag mark carving a dark path from the water's edge into the vegetation. The beach is textured with rippled sand, sea foam, broken crate planks, torn black fabric, scattered debris, and small glowing blue shells embedded along the trail. Warm pink-orange dawn light reflects across the shallow water and slick sand, creating a cinematic mystery-adventure mood. There is no dynamic camera movement and no action taken by the unseen observer; the world moves independently as waves wash over the first part of the mark, palm fronds sway, birds circle over the ocean, and clouds drift through the glowing sky.

Prompt A first-person view from a strictly stationary observation point at a T-shaped intersection inside an abandoned underground sci-fi research facility. The spatial layout splits into three distinct routes: a left corridor submerged in shallow water, a right corridor filled with warm steam, and a heavy circular metal door straight ahead, half-open onto deep darkness. The architecture is industrial and bunker-like, with ribbed metal tunnel frames, stained concrete walls, corroded panels, loose floor cables, broken glass, and wet reflective plating. Cold blue emergency lights wash the flooded passage, while orange warning lamps burn through haze on the opposite side, creating a tense, cinematic sci-fi horror atmosphere. There is no dynamic camera movement and no action taken by the unseen observer; the world moves independently as ceiling lights flicker, water ripples across the floor, steam drifts through the right corridor, and dust motes float in the stale air.

Stage 1 Refined

Prompt

A first-person view from a strictly stationary observation point on an elevated forest ledge before a massive ancient doorway carved into a cliff. Stone steps form a clear approach from mossy path to half-open doors, flanked by carved pillars, guardian statues, ivy-covered walls, and a sweeping mountain valley to the left. A cloaked traveler stands near the entrance as a scale marker. Surfaces are textured with cracked stone slabs, engraved masonry, damp moss, tangled vines, fallen leaves, weathered statues, and glowing turquoise runes etched across the ground. Warm late-day sunlight mixes with intense cyan light spilling from the doorway, creating a tense fantasy atmosphere of discovery. There is no dynamic camera movement and no action taken by the person filming; the perspective remains fixed. Autonomous motion continues as leaves swirl, birds scatter from the cliff, vines tremble, and the portal light pulses softly.

Stage 1 Refined

Prompt

A first-person view from a strictly stationary observation point overlooks an abandoned winter campsite in a snowy pine basin beneath a rocky mountain slope. The spatial layout places a glowing campfire and scattered gear in the left foreground, a lone mountaineer in an orange jacket near center, and a footprint trail crossing open snow toward a cave cut into the cliff. Distant peaks and dark conifers frame the depth. Materials are cold and tactile: powdery snow, ice-dusted rocks, singed firewood, metal cups, canvas supplies, frosted backpack fabric, and rough bark. Purple dusk light cools the landscape, while fire embers and golden cave light add uneasy warmth. There is no dynamic camera movement and no action by the unseen observer; the world moves independently as snow falls, pine branches sway, embers flicker, steam rises from the cup, and the cave glow pulses softly.

Stage 1 Refined

Prompt

A first-person view from a strictly stationary observation point inside a submerged ancient temple. A clear stone walkway runs between coral-encrusted columns toward a cracked ceremonial wall, where bright green light leaks through the central fracture and aligns with glowing symbols on the floor. A small spherical diving robot hovers ahead, its blue front light illuminating broken statues, scattered masonry, sand patches, seaweed, purple coral, and barnacle-covered pillars. The textures are eroded and waterworn, with carved stone softened by algae, silt, and marine growth. Shafts of sunlight descend from the surface, mixing with the green fissure glow to create a calm, mysterious underwater atmosphere. The observer's perspective remains fixed, with no dynamic camera movement and no actions taken by the person recording. Autonomous motion continues as fish swim, bubbles rise, particles drift, seaweed sways, caustics shimmer, and the green symbols pulse faintly.
