OpenAI has launched GPT-5.4, which the company describes as its most capable and efficient frontier model for professional work. The release includes Pro and Thinking variants, though specific technical specifications and pricing remain unclear.
Frontier language models including GPT-5.2 and Claude 4.6 experience accuracy degradation of up to 33% as conversations lengthen, according to new research. The finding suggests that extended context use within a single conversation introduces performance challenges even in state-of-the-art models.
Alibaba has released the Qwen 3.5 series, an open-source model that claims performance comparable to frontier proprietary models while running on commodity hardware. The release signals a shift in AI model economics, offering enterprises lower inference costs and greater deployment flexibility than closed alternatives.
