OpenAI previews Sora, the first text-to-video model that looked like it was working

Products & Tools

Event Summary

Sora: OpenAI’s February 2024 text-to-video model that stunned the world with realistic AI-generated videos. Timeline of how video generation entered the mainstream.

Impact Assessment

  • Capability Leap +3 · Medium-term

    First text-to-video model to demonstrate object permanence, coherent motion, and cinematic quality at up to one minute length. The diffusion transformer architecture (combining diffusion with Transformers) proved transferable from image to video generation, suggesting a convergence path for generative AI architectures.

    Affected Groups: AI researchers, filmmakers, VFX artists, content creators

  • Economic Disruption -2 · Short-term

    Threatened the economics of physical film production, stock footage, and advertising video creation. Tyler Perry halted an $800M studio expansion. The visual effects and advertising industries began reassessing their cost structures. Competitors (Runway, Pika, Adobe, Google) accelerated video generation R&D.

    Affected Groups: film industry, advertisers, stock footage providers, VFX artists

  • Risk Creation -2 · Immediate

    Accelerated concerns about AI-generated deepfakes, misinformation through synthetic video, and the erosion of visual evidence in journalism, law, and politics. The 2024 global election year made these concerns especially acute.

    Affected Groups: journalists, policymakers, legal professionals, general public

"Attention Is All You Need" — the Transformer architecture is born

Eight Google researchers published 'Attention Is All You Need' at NeurIPS 2017, introducing the Transformer architecture. By dispensing with recurrence and convolution entirely and relying solely on self-attention mechanisms, the Transformer achieved state-of-the-art translation results while training significantly faster. The paper has been cited over 250,000 times, and the Transformer became the foundation of every major AI system since—from GPT and BERT to AlphaFold and modern speech models.

Stable Diffusion open-sources text-to-image generation to the public

Stability AI released Stable Diffusion in August 2022, an open-weight text-to-image model that could generate high-quality images from natural language descriptions on consumer-grade GPUs. Unlike DALL-E 2 (closed API) and Midjourney (proprietary), Stable Diffusion's weights were released publicly, sparking an explosion of community tools, fine-tunes, and creative applications. It transformed AI art from a curiosity into a mass phenomenon practically overnight.

OpenAI launches ChatGPT, reaching 100 million users in two months

OpenAI released ChatGPT, a conversational AI product based on GPT-3.5, free to the public on November 30, 2022. It reached 1 million users in 5 days and 100 million in 2 months, becoming the fastest-growing consumer application in history. The launch marked the moment AI became a mainstream conversation—not just for researchers and tech enthusiasts, but for policymakers, teachers, artists, and the general public worldwide.

OpenAI releases GPT-4o, bringing real-time voice conversation to everyone

On May 13, 2024, OpenAI released GPT-4o ('omni'), a natively multimodal model combining text, vision, and audio processing in a single neural network. For the first time, users could have real-time voice conversations with an AI that could express emotion, laugh, pause, and adjust its tone — indistinguishable from human conversation. GPT-4o matched GPT-4 on text benchmarks while dramatically improving voice and vision performance. The model was made free for all ChatGPT users, effectively doubling the available AI capability overnight.

Apple announces Apple Intelligence at WWDC, bringing on-device AI to over a billion devices

On June 10, 2024, Apple announced Apple Intelligence at WWDC, marking the company's formal entry into the AI race. The personal intelligence system integrated generative AI models into iPhone, iPad, and Mac operating systems with a privacy-first architecture that processed most data on-device. Apple also announced a partnership with OpenAI to integrate ChatGPT into Siri and system-wide writing tools. The announcement signaled that AI had become a core platform feature, not a standalone product.

OpenAI discontinues Sora, marking the first major product shutdown by a frontier AI lab

On April 26, 2026, OpenAI discontinued Sora, its text-to-video generation tool, shutting down both the web and app experiences. The shutdown came just over two years after Sora's spectacular February 2024 preview, which had been hailed as a breakthrough in AI video generation. OpenAI cited the high cost of video generation inference, limited product-market fit, and the emergence of more cost-effective competitors (Google's Veo 3, open-source alternatives) as factors. Sora became the first high-profile product casualty of the AI industry's intensifying cost and competition pressures.
