Vi lærer opp KI til å forstå og simulere den fysiske verden i bevegelse, med mål om å trene opp modeller som kan hjelpe mennesker med å løse problemer som krever interaksjon i den virkelige verden.
Vi introduserer Sora, tekst-til-video-modellen vår. Sora kan generere videoer på opptil ett minutt som holder høy visuell kvalitet og stemmer med brukerens melding.
Melding: A stylish woman walks down a Tokyo street filled with warm glowing neon and animated city signage. She wears a black leather jacket, a long red dress, and black boots, and carries a black purse. She wears sunglasses and red lipstick. She walks confidently and casually. The street is damp and reflective, creating a mirror effect of the colorful lights. Many pedestrians walk about.
Melding: Several giant wooly mammoths approach treading through a snowy meadow, their long wooly fur lightly blows in the wind as they walk, snow covered trees and dramatic snow capped mountains in the distance, mid afternoon light with wispy clouds and a sun high in the distance creates a warm glow, the low camera view is stunning capturing the large furry mammal with beautiful photography, depth of field.
Melding: A movie trailer featuring the adventures of the 30 year old space man wearing a red wool knitted motorcycle helmet, blue sky, salt desert, cinematic style, shot on 35mm film, vivid colors.
Melding: Drone view of waves crashing against the rugged cliffs along Big Sur’s garay point beach. The crashing blue waters create white-tipped waves, while the golden light of the setting sun illuminates the rocky shore. A small island with a lighthouse sits in the distance, and green shrubbery covers the cliff’s edge. The steep drop from the road down to the beach is a dramatic feat, with the cliff’s edges jutting out over the sea. This is a view that captures the raw beauty of the coast and the rugged landscape of the Pacific Coast Highway.
Melding: Animated scene features a close-up of a short fluffy monster kneeling beside a melting red candle. The art style is 3D and realistic, with a focus on lighting and texture. The mood of the painting is one of wonder and curiosity, as the monster gazes at the flame with wide eyes and open mouth. Its pose and expression convey a sense of innocence and playfulness, as if it is exploring the world around it for the first time. The use of warm colors and dramatic lighting further enhances the cozy atmosphere of the image.
Melding: A gorgeously rendered papercraft world of a coral reef, rife with colorful fish and sea creatures.
Melding: This close-up shot of a Victoria crowned pigeon showcases its striking blue plumage and red chest. Its crest is made of delicate, lacy feathers, while its eye is a striking red color. The bird’s head is tilted slightly to the side, giving the impression of it looking regal and majestic. The background is blurred, drawing attention to the bird’s striking appearance.
Melding: Photorealistic closeup video of two pirate ships battling each other as they sail inside a cup of coffee.
Melding: A young man at his 20s is sitting on a piece of cloud in the sky, reading a book.
I dag blir Sora gjort tilgjengelig for red team-medlemmer for å vurdere kritiske områder for skade eller risiko. Vi gir også tilgang til en rekke visuelle kunstnere, designere og filmskapere for å få tilbakemeldinger på hvordan modellen best kan videreutvikles for å være til nytte for kreative bruk.
Vi deler forskningsfremgangen vår tidlig for å begynne å samarbeide med og få tilbakemeldinger fra folk utenfor OpenAI, og for å gi allmennheten et innblikk i hvilke KI-muligheter som er i vente.

Melding: A petri dish with a bamboo forest growing within it that has tiny red pandas running around.
Melding: The camera rotates around a large stack of vintage televisions all showing different programs — 1950s sci-fi movies, horror movies, news, static, a 1970s sitcom, etc, set inside a large New York museum gallery.
Melding: 3D animation of a small, round, fluffy creature with big, expressive eyes explores a vibrant, enchanted forest. The creature, a whimsical blend of a rabbit and a squirrel, has soft blue fur and a bushy, striped tail. It hops along a sparkling stream, its eyes wide with wonder. The forest is alive with magical elements: flowers that glow and change colors, trees with leaves in shades of purple and silver, and small floating lights that resemble fireflies. The creature stops to interact playfully with a group of tiny, fairy-like beings dancing around a mushroom ring. The creature looks up in awe at a large, glowing tree that seems to be the heart of the forest.
Sora kan generere komplekse scener med flere figurer, spesifikke typer bevegelser og nøyaktige detaljer på både motivet og bakgrunnen. Modellen forstår ikke bare hva brukeren har bedt om i meldingen, men også hvordan disse tingene eksisterer i den fysiske verden.
Melding: The camera follows behind a white vintage SUV with a black roof rack as it speeds up a steep dirt road surrounded by pine trees on a steep mountain slope, dust kicks up from it’s tires, the sunlight shines on the SUV as it speeds along the dirt road, casting a warm glow over the scene. The dirt road curves gently into the distance, with no other cars or vehicles in sight. The trees on either side of the road are redwoods, with patches of greenery scattered throughout. The car is seen from the rear following the curve with ease, making it seem as if it is on a rugged drive through the rugged terrain. The dirt road itself is surrounded by steep hills and mountains, with a clear blue sky above with wispy clouds.
Melding: Reflections in the window of a train traveling through the Tokyo suburbs.
Melding: A drone camera circles around a beautiful historic church built on a rocky outcropping along the Amalfi Coast, the view showcases historic and magnificent architectural details and tiered pathways and patios, waves are seen crashing against the rocks below as the view overlooks the horizon of the coastal waters and hilly landscapes of the Amalfi Coast Italy, several distant people are seen walking and enjoying vistas on patios of the dramatic ocean views, the warm glow of the afternoon sun creates a magical and romantic feeling to the scene, the view is stunning captured with beautiful photography.
Melding: A large orange octopus is seen resting on the bottom of the ocean floor, blending in with the sandy and rocky terrain. Its tentacles are spread out around its body, and its eyes are closed. The octopus is unaware of a king crab that is crawling towards it from behind a rock, its claws raised and ready to attack. The crab is brown and spiny, with long legs and antennae. The scene is captured from a wide angle, showing the vastness and depth of the ocean. The water is clear and blue, with rays of sunlight filtering through. The shot is sharp and crisp, with a high dynamic range. The octopus and the crab are in focus, while the background is slightly blurred, creating a depth of field effect.
Melding: A flock of paper airplanes flutters through a dense jungle, weaving around trees as if they were migrating birds.
Melding: A cat waking up its sleeping owner demanding breakfast. The owner tries to ignore the cat, but the cat tries new tactics and finally the owner pulls out a secret stash of treats from under the pillow to hold the cat off a little longer.
Melding: Borneo wildlife on the Kinabatangan River
Melding: A Chinese Lunar New Year celebration video with Chinese Dragon.
Modellen har en dyp forståelse av språk, noe som gjør at den kan tolke meldinger presist og generere engasjerende karakterer som uttrykker sterke følelser. Sora kan også lage flere opptak i én og samme genererte video, der karakterer og visuell stil bevares gjennom hele videoen.
Melding: Tour of an art gallery with many beautiful works of art in different styles.

Melding: An extreme close-up of an gray-haired man with a beard in his 60s, he is deep in thought pondering the history of the universe as he sits at a cafe in Paris, his eyes focus on people offscreen as they walk as he sits mostly motionless, he is dressed in a wool coat suit coat with a button-down shirt , he wears a brown beret and glasses and has a very professorial appearance, and the end he offers a subtle closed-mouth smile as if he found the answer to the mystery of life, the lighting is very cinematic with the golden light and the Parisian streets and city in the background, depth of field, cinematic 35mm film.
Melding: A beautiful silhouette animation shows a wolf howling at the moon, feeling lonely, until it finds its pack.
Melding: New York City submerged like Atlantis. Fish, whales, sea turtles and sharks swim through the streets of New York.
Melding: A litter of golden retriever puppies playing in the snow. Their heads pop out of the snow, covered in.
Det er fortsatt rom for å forbedre den nåværende modellen. Den kan ha vanskeligheter med å simulere fysikken i en kompleks scene og forstår kanskje ikke bestemte sammenhenger mellom årsak og virkning (for eksempel: en kjeks vil kanskje ikke ha bitemerker etter at en karakter har tatt en bit). Modellen kan også forveksle romlige detaljer i en melding, som å skille mellom høyre og venstre, eller slite med nøyaktige beskrivelser av hendelser som utspiller seg over tid – for eksempel spesifikke kamerabevegelser.
Melding: Step-printing scene of a person running, cinematic film shot in 35mm.
Svakhet: Sora lager noen ganger fysisk usannsynlige bevegelser.
Melding: Five gray wolf pups frolicking and chasing each other around a remote gravel road, surrounded by grass. The pups run and leap, chasing each other, and nipping at each other, playing.
Svakhet: Dyr eller personer kan dukke opp spontant, spesielt i scener med mange elementer.
Melding: Basketball through hoop then explodes.
Svakhet: Et eksempel på unøyaktig fysisk modellering og unaturlig deformering av objekter.
Melding: Archeologists discover a generic plastic chair in the desert, excavating and dusting it with great care.
Svakhet: I dette eksempelet klarer ikke Sora å modellere stolen som et fast objekt, noe som fører til unøyaktige fysiske interaksjoner.
Melding: A grandmother with neatly combed grey hair stands behind a colorful birthday cake with numerous candles at a wood dining room table, expression is one of pure joy and happiness, with a happy glow in her eye. She leans forward and blows out the candles with a gentle puff, the cake has pink frosting and sprinkles and the candles cease to flicker, the grandmother wears a light blue blouse adorned with floral patterns, several happy friends and family sitting at the table can be seen celebrating, out of focus. The scene is beautifully captured, cinematic, showing a 3/4 view of the grandmother and the dining room. Warm color tones and soft lighting enhance the mood..
Svakhet: Å simulere komplekse interaksjoner mellom objekter og flere personer er ofte en utfordring for modellen og kan noen ganger føre til komiske resultater.
Vi kommer til å treffe flere viktige sikkerhetstiltak før vi gjør Sora tilgjengelig som et av OpenAIs produkter. Vi samarbeider med red team-medlemmer – fageksperter innen områder som feilinformasjon, hatefullt innhold og bias – som gjør omfattende angrepstesting av modellen.
Vi utvikler også verktøy som kan oppdage villedende innhold, som en detektor som kan identifisere om en video er generert av Sora. Vi planlegger å inkludere C2PA-metadata(åpnes i et nytt vindu) i fremtiden dersom vi lanserer modellen i et OpenAI-produkt.
I tillegg til å utvikle nye teknikker for å forberede implementering, bruker vi eksisterende sikkerhetsmetoder(åpnes i et nytt vindu) vi allerede har utviklet for produkter som benytter DALL·E 3, og som også gjelder for Sora.
For eksempel: Når modellen inngår i et OpenAI-produkt, vil tekstklassifiseringen vår identifisere og avvise meldinger som bryter med retningslinjene for bruk, som forespørsler om ekstrem vold, seksuelt innhold, hatefulle bilder, likhet med kjendiser eller andres immaterielle rettigheter. Vi har også utviklet robuste bildeklassifikatorer som analyserer bildene i hver video som genereres før den vises til brukeren, for å sikre at den overholder retningslinjene våre.
Vi kommer til å inkludere politikere, lærere og kunstnere over hele verden for å høre bekymringene deres og identifisere positive bruksområder for den nye teknologien. Til tross for omfattende research og testing, kan vi ikke forutsi alle måtene teknologien vår vil bli brukt på, eller alle måtene den potensielt kan misbrukes på. Derfor mener vi at læring gjennom faktisk bruk er en avgjørende del av det å utvikle og lansere stadig tryggere KI-systemer over tid.
Melding: The camera directly faces colorful buildings in Burano Italy. An adorable dalmation looks through a window on a building on the ground floor. Many people are walking and cycling along the canal streets in front of the buildings.
Melding: An adorable happy otter confidently stands on a surfboard wearing a yellow lifejacket, riding along turquoise tropical waters near lush tropical islands, 3D digital render art style.

Melding: A white and orange tabby cat is seen happily darting through a dense garden, as if chasing something. Its eyes are wide and happy as it jogs forward, scanning the branches, flowers, and leaves as it walks. The path is narrow as it makes its way between all the plants. the scene is captured from a ground-level angle, following the cat closely, giving a low and intimate perspective. The image is cinematic with warm tones and a grainy texture. The scattered daylight between the leaves and plants above creates a warm contrast, accentuating the cat’s orange fur. The shot is clear and sharp, with a shallow depth of field.
Melding: Aerial view of Santorini during the blue hour, showcasing the stunning architecture of white Cycladic buildings with blue domes. The caldera views are breathtaking, and the lighting creates a beautiful, serene atmosphere.

Melding: The Glenfinnan Viaduct is a historic railway bridge in Scotland, UK, that crosses over the west highland line between the towns of Mallaig and Fort William. It is a stunning sight as a steam train leaves the bridge, traveling over the arch-covered viaduct. The landscape is dotted with lush greenery and rocky mountains, creating a picturesque backdrop for the train journey. The sky is blue and the sun is shining, making for a beautiful day to explore this majestic spot.
Sora er en diffusjonsmodell som genererer video ved å starte med noe som ligner statisk støy, og gradvis endre det ved å fjerne støyen gjennom mange trinn.
Sora kan generere hele videoer på én gang eller utvide genererte videoer for å gjøre dem lengre. Ved å gi modellen oversikt over mange bilder samtidig, har vi løst en krevende utfordring med å sørge for at et motiv forblir det samme selv når det er midlertidig ute av bildet.
På samme måte som GPT‑modellene bruker Sora en transformer-arkitektur som gir uovertruffen skaleringsytelse.
Vi representerer videoer og bilder som samlinger av mindre enheter med data kalt «pakker», som fungerer omtrent som tokener i GPT. Ved å standardisere hvordan vi representerer data, kan vi trene diffusjonstransformatorer på et bredere spekter av visuelle data enn tidligere – med ulike varigheter, oppløsninger og bildeformater.
Sora bygger videre på tidligere research i DALL·E- og GPT‑modellene. Det bruker «recaptioning»-teknikken fra DALL·E 3, som innebærer å generere svært beskrivende bildetekster for det visuelle datasettet som brukes til opplæring. Dette gjør at modellen kan følge brukerens tekstinstruksjoner mer nøyaktig i videoen som genereres.
I tillegg til å kunne generere en video utelukkende fra tekstinstruksjoner, kan modellen også ta et eksisterende stillbilde og generere en video basert på det – der bildet animeres nøyaktig og med øye for de små detaljene. Modellen kan også ta en eksisterende video og enten forlenge den eller fylle inn manglende bilder. Les mer i den tekniske rapporten.
Sora fungerer som et fundament for modeller som kan forstå og simulere den virkelige verden – noe vi mener vil være et viktig skritt på veien mot AGI.
