OpenAI expands Sora API with 1080p output, 20-second generations, and character references
OpenAI updated the Sora API to support reusable character references, video generations up to 20 seconds, 1080p output for the sora-2-pro model, video extensions, and Batch API support for video endpoints. The 1080p tier on sora-2-pro is priced at $0.70 per second. These additions meaningfully expand Sora's production utility for developers building video generation workflows.
OpenAI updates gpt-realtime-mini and gpt-audio-mini slugs to 2025-12-15 snapshots
OpenAI has updated the rolling model slugs gpt-realtime-mini and gpt-audio-mini to point to the 2025-12-15 model snapshots, replacing the previous 2025-10-06 versions. Developers needing the older snapshots can pin to gpt-realtime-mini-2025-10-06 and gpt-audio-mini-2025-10-06 explicitly. This is a routine API maintenance update affecting audio and realtime model endpoints.
OpenAI updates gpt-5.2-chat-latest slug to current ChatGPT model
OpenAI updated the gpt-5.2-chat-latest API alias to point to the latest model version deployed in ChatGPT. This is a routing change to an API slug rather than a new model release, but signals a model version update in production. The change is relevant for API consumers who rely on the latest-slug for automatic model tracking.
OpenAI updates gpt-4o-mini-tts and gpt-4o-mini-transcribe slugs to 2025-12-15 snapshots
OpenAI has updated the floating model slugs for gpt-4o-mini-tts and gpt-4o-mini-transcribe to point to their 2025-12-15 snapshots, with the previous March 2025 snapshots remaining accessible via versioned identifiers. Notably, OpenAI now recommends gpt-4o-mini-transcribe over gpt-4o-transcribe for best transcription results, signaling a quality improvement in the mini-tier audio model.
OpenAI updates gpt-5.3-chat-latest API slug to current ChatGPT model
OpenAI updated the gpt-5.3-chat-latest API alias to point to the latest model deployed in ChatGPT. This is a routing change for API consumers who rely on the versioned slug rather than pinned model identifiers. The update signals a model version bump within the GPT-5.3 series.
OpenAI Shuts Down Sora Video Generation Model, Redirects Team to World Models and Robotics
OpenAI is discontinuing its Sora video generation model, with web/app access ending April 26 and API access closing September 24, 2026. The model was losing roughly $1 million per day, with daily active users falling below 500,000 after peaking at 1 million post-mobile launch. The Sora team will be redirected to longer-term projects including world models and robotics, while compute resources have already been diverted to a new coding/enterprise model codenamed Spud. The shutdown also effectively ends OpenAI's high-profile partnership with Disney, which had planned to invest up to $1 billion contingent on Sora integration.
Sora 2 is here
OpenAI has released Sora 2, its latest video generation model, claiming improvements in physical accuracy, realism, and controllability over prior versions. The model introduces synchronized dialogue and sound effects as new capabilities. It is available through a new dedicated Sora app.
Sora 2 System Card
OpenAI has released Sora 2, a new state-of-the-art video and audio generation model that builds on the original Sora. Key improvements include more accurate physics simulation, sharper realism, synchronized audio generation, enhanced steerability, and broader stylistic range. The accompanying system card documents safety evaluations and deployment considerations for the model.
