OpenAI's GPT-5.2 debuts; Disney invests $1B

12 Dec 2025 OpenAI has launched GPT-5.2 (internal codename “Garlic”), a new flagship model aimed at coding and agentic workflows. The model supports an enormous 400,000‑token context window (roughly 300k words), can emit up to 128,000 tokens per response, and includes reasoning‑token features to tackle complex problem solving and end‑to‑end codebase tasks. OpenAI positions GPT‑5.2 for enterprise agent use cases; pricing is set at $1.75 per million input tokens and $14 per million output tokens — about 40% higher than GPT‑5 according to the announcement. Simultaneously, Disney announced a $1 billion equity investment in OpenAI and became the first major content partner for Sora. Under the deal Disney gets broad commercial access and deployment rights: Sora access to generate short videos using 200+ Disney/Pixar/Marvel/Star Wars characters (with curated fan content appearing on Disney+), internal API deployment including company‑wide ChatGPT use, and warrants tied to the equity investment. The partnership is framed around responsible AI and creator protections, and the companies emphasize licensing limits for likenesses and voices. The combined product + strategic deal marks one of 2025’s largest enterprise AI moves and signals a shift from pilots to large‑scale integration of advanced LLMs across media and production pipelines.
