Model Releases and Performance Advances
OpenAI’s GPT-5.4 “Thinking” Model represents a significant leap in reasoning capabilities, scoring 83.0% on the GDPVal benchmark—placing it at or above human expert levels on economically valuable tasks[2]. The model emphasizes improved step-by-step reasoning, coding capability, and cost efficiency[7]. Google countered with Gemini 3.1 Flash-Lite for cost-efficient developer workloads and a “Deep Think” variant that autonomously solved four open math problems and scored 90% on the IMO-ProofBench Advanced[7].
