AI Explained breaks down the April 23-24 dual launch: GPT-5.5 (OpenAI) and DeepSeek V4 (MIT license, 1.6T params MoE). DeepSeek V4-Pro costs roughly 1/7th of GPT-5.5 and 1/6th of Opus 4.7, with cached inputs widening the gap to 1/10th. GPT-5.5 still leads on Terminal-Bench 2.0 (82.7% vs 67.9%) but DeepSeek's open-weight model at this price point intensifies the compute war narrative.
