Artificial intelligence firm OpenAI unveiled its first-ever text-to-video model to a strong reception on Thursday, though the firm admits the model still has a ways to go.  OpenAI unveiled the new generative AI model, dubbed Sora, on Feb. 15, which is said to create detailed videos from simple text prompts, continue existing videos, and even generate scenes based on a still image. Introducing Sora, our text-to-video model.Sora can create videos of up to 60 seconds featuring highly detailed scenes, complex camera motion, and multiple characters with vibrant emotions. https://t.co/7j2JN27M3WPrompt: “Beautiful, snowy… pic.twitter.com/ruTEWn87vf — OpenAI (@OpenAI) February 15, 2024 According to a Feb. 15 blog post, OpenAI claimed the AI model can generate movie-like scenes in up to resolution up to 1080p. These scenes can include multiple characters, specific types of motion, and accurate details of the subject and background. How Sora works Much like OpenAI’s image-based predecessor DALL-E 3, Sora operates on what’s known as a “diffusion” model. Diffusion refers to a generative AI model creating its output by generating a video or an image with something that looks more like “static noise” and then gradually transforming it by “removing the noise” over several steps. Announcing Sora — our model which creates minute-long videos from a text prompt: https://t.co/SZ3OxPnxwz pic.twitter.com/0kzXTqK9bG — Greg Brockman (@gdb) February 15, 2024 The AI firm wrote that Sora has been built on past research from both GPT and DALL-E3 models, something the firm claims makes the model better at more “faithfully” representing user inputs. OpenAI admitted that Sora still contained several weaknesses, and could struggle to accurately simulate the physics of a complex scene, namely by muddling up the nature of cause and effect. “For example, a person might take a bite out of a cookie, but afterward, the cookie may not have a bite mark." The new tool can also confuse the “spatial details” of a given prompt by mixing up lefts and rights or failing to follow precise descriptions of directions, said the firm. Sora can accidentally generate physically implausible motion. Source: OpenAI OpenAI said the new generative model is only available for now to “red teamers” — tech parlance for cybersecurity researchers — to assess “critical areas for harms or risks” as well as select designers, visual artists, and filmmakers to gather feedback on how to advance the model. In December 2023, a report from Stanford University revealed that AI-powered image-generation tools using the AI database LAION, were being trained on thousands of images of illegal child abuse material, something that raises serious ethical and legal concerns for text-to-image or video models. Users on X left “speechless” Dozens of video demos have been circulating on X showing examples of Sora in action, while Sora is now trending on X with over 173,000 posts. In a bid to show off what the new generative model is capable of, OpenAI CEO Sam Altman opened himself up to custom video-generation requests from users on X, with the AI chief sharing a total of seven Sora-generated videos, varying from a duck on dragon back to golden retrievers recording a podcast on a mountain top. https://t.co/uCuhUPv51N pic.twitter.com/nej4TIwgaP — Sam Altman (@sama) February 15, 2024 AI commentator Mckay Wrigley — along with many others — wrote that the video generated by Sora had left him “speechless.” In a Feb. 15 post to X, Nvidia senior researcher Jim Fan declared that anyone who believed Sora to be just another “creative toy,” like DALL-E 3, would be dead wrong. If you think OpenAI Sora is a creative toy like DALLE, ... think again. Sora is a data-driven physics engine. It is a simulation of many worlds, real or fantastical. The simulator learns intricate rendering, "intuitive" physics, long-horizon reasoning, and semantic grounding, all… pic.twitter.com/pRuiXhUqYR — Jim Fan (@DrJimFan) February 15, 2024 In Fan’s view, Sora is less a video-generation tool and more a “data-driven physics engine,” as the AI model isn’t just generating abstract video but also deterministically creating the physics of objects in the scene itself.

In a significant turn of events, OpenAI has reinstated Sam Altman as CEO, just a week after his abrupt removal by the company’s board. This decision marks a new chapter for the AI research firm, which is also welcoming Microsoft in a non-voting capacity on its newly restructured board. Altman’s return follows a period of controversy, where the OpenAI board cited a lack of candor in his communications as the reason for his initial dismissal. The board’s lack of confidence in his leadership led to the appointment of CTO Mira Murati as interim CEO. Altman praised Murati’s exceptional leadership during this transitional phase, confirming her return to the CTO role. OpenAI Restructuring and Microsoft’s Involvement The newly formed OpenAI board will see Bret Taylor assuming the role of Chair, replacing Greg Brockman. The board will also include economist Larry Summers, Quora co-founder and CEO Adam D’Angelo, and a non-voting observer from Microsoft, the company’s largest investor. Altman emphasized the board’s diversity and experience, reflecting the multifaceted mission of OpenAI. Altman also addressed potential conflict of interest concerns regarding Adam D’Angelo’s dual role as a board member and CEO of Quora and Poe. He assured that D’Angelo had been transparent and responsible in managing these concerns. The reappointment of Altman and Brockman as CEO and President respectively, only 72 hours after their departure, signifies a strong comeback. Altman expressed gratitude towards Microsoft’s leadership for their support during this tumultuous period and is optimistic about the future of their partnership. As OpenAI continues its journey in building beneficial AGI, the return of its co-founder and the new board dynamics are set to influence the direction and governance of one of the leading entities in AI research.

The token associated with Sam Altman’s eye-scanning cryptocurrency project surged on Wednesday after he was reinstated as the CEO of artificial intelligence giant OpenAI. Sam Altman Restored As OpenAI CEO Sam Altman is returning to OpenAI nearly a week after he was ousted from the company’s board, prompting a job offer from Microsoft CEO Satya Nadella. The ChatGPT developer announced that it had reached an “agreement in principle” for Altman to return as the chief executive officer. According to OpenAI, the firm and Altman “are collaborating to figure out the details.” In a statement on the X platform following the news of his rehiring, Altman expressed his “love” for OpenAI, noting that “everything I’ve done over the past few days has been in service of keeping this team and its mission together.” He added:  “I’m looking forward to returning to OpenAI.” OpenAI co-founder and president Greg Brockman, who quit after Altman was forced to depart from the company, will also return.  Returning to OpenAI & getting back to coding tonight. — Greg Brockman (@gdb) November 22, 2023 Crucially, Altman’s reinstatement also entails OpenAI appointing a new board consisting of chair Bret Taylor, Larry Summers, and Adam D’Angelo. Following the news of Altman’s return, Microsoft’s Nadella posited that, “We are encouraged by the changes to the OpenAI board. We believe this is a first essential step on a path to more stable, well-informed, and effective governance.” OpenAI’s Rocky Week Sam Altman was dismissed last week because he “was not consistently candid in his communications” with OpenAI’s board. This led to a loss of confidence in his leadership by the board. Brockman resigned from the firm in solidarity with Altman, with Microsoft tapping the duo to lead a new advanced artificial intelligence research team.  Altman’s unceremonious firing prompted hundreds of OpenAI employees to threaten a walkout to join Altman in his new venture unless the board resigned.  Worldcoin (WLD) — which was launched just six months ago — slumped to as low as $1.87 on November 17 after Altman was abruptly pushed out by OpenAI. WLD has notched an 8.1% rise to trade for $2.54 per coin today and has a market capitalization of $294 million following news of his return.
