Video AI startup Genmo has just launched Mochi-1, an open-source model (Apache 2.0) designed to compete with industry leaders like Runway and Kling.
On October 22, Genmo, the AI based video generating platform, released Mochi 1, a new state-of-the-art open-source text-to-video generation model.
Genmo launches mochi 1 text-to-video generation model, but server crashes within hours.
In tandem with the Mochi 1 preview, Genmo also announced it has raised a $28.4 million Series A funding round, led by NEA, with additional participation from The House Fund, Gold House Ventures, WndrCo, Eastlink Capital Partners, and Essence VC.
Generative AI has revolutionized the way we create and interact with digital content. Since the launch of Dall-E in July 2022 and ChatGPT in November 2022, the field has seen unprecedented growth. This technology, initially popularized by OpenAI’s ChatGPT, has now been embraced by major tech players like Microsoft and Google, as well as a plethora of innovative startups. These advancements offer solutions for generating a diverse range of outputs including text, images, video, audio, and other media from simple prompts.The consumer now has a vast array of options based on their specific output needs and use cases. From generic, large-scale, multi-modal models like OpenAI’s ChatGPT and Google’s Bard to specialized solutions tailored for specific use cases and sectors like finance and legal advice, the choices are vast and varied. For instance, in the financial sector, tools like BloombergGPT (https://www.bloomberg.com/), FinGPT (https://fin-gpt.org/), StockGPT (https://www.askstockgpt.com/) or BeeBee.AI (https://www.beebee.ai/) or in the domain of legal advise, tools like Law Chat GPT (https://lawchatgpt.com/) or LegalFly (https://www.legalfly.ai/), offer niche solutions with heightened accuracy.To give an idea of what is available on the market, here is a short overview of some notable solutions available:General Chatting and Writing Assistance: : Bard (Google): https://bardai.io/ ChatFlash (Neuroflash AI): https://neuroflash.com/chatflash/ ChatGPT (OpenAI): https://chat.openai.com/chat Claude (Anthropic): https://claude.ai/ Copy AI: https://www.copy.ai Easy Peasy AI Chat: https://easy-peasy.ai Fireflies (https://www.unite.ai/goto/fireflies) GrowthBar: https://growthbarseo.com Jasper AI: https://www.jasper.ai Llama 2 (Meta): https://ai.meta.com/llama/ Notion AI: https://www.notion.so/ Perplexity: https://www.perplexity.ai Quillbot: https://quillbot.com Rytr Chat: https://rytr.me Rytr: https://rytr.me/ Wordtune: https://www.wordtune.com/ Writesonic: https://writesonic.comArt and Picture generation : this can be generating new pictures from a prompt, but also adapting existing pictures (like enhancing, removing parts of a picture, inserting object into a picture…): Adobe Firefly: https://www.adobe.com/sensei/generative-ai/firefly.htm Artbreeder: https://www.artbreeder.com/ Auto Draw: https://autodraw.com BRIA: https://bria.ai/ Canva: https://www.canva.com/ai-image-generator/ Craiyon: https://www.craiyon.com/ Dall-E 2 (OpenAI): https://openai.com/product/dall-e-2 Deep Dream Generator: https://deepdreamgenerator.com/ DeepAI: https://deepai.org/machine-learning-model/text2img Deepswap: https://www.deepswap.ai Flair AI: https://flairai.io Fotor: https://www.fotor.com/features/ai-image-generator/ Images.ai (unite.ai): https://images.ai/ Jasper Art: https://www.jasper.ai/art Leap AI: https://www.tryleap.ai/ Lensa AI: https://prisma-ai.com/lensa MidJourney: https://www.midjourney.com/home/ Neural Doodle: https://neuraldoodle.com/ NightCafe: https://creator.nightcafe.studio PhotoSonic (Writesonic): https://writesonic.com/photosonic-ai-art-generator Pictory: https://pictory.io Pikazo: https://www.pikazoapp.com/ Pixray: https://replicate.com/pixray/text2image Prodia: https://app.prodia.com/ Remini: https://remini.ai/ RocketAI: https://www.rocketai.io/ Simplified: https://simplified.com/ Stable Diffusion (DreamStudio): https://stablediffusionweb.com/ Stablecog: https://stablecog.com/Video generation : this can be based on "prompts" resulting in video, taking a picture and identifying which part should be moving or providing a set of pictures asking the solution to interpolate the movement between 2 consecutive pictures (thus transforming a set of pictures into a movie)
