OpenAI has launched GPT-5.4, introducing both Pro and Thinking versions in a bid to expand its model lineup across different use cases and price points. The new release comes as competition intensifies in the large language model market, with OpenAI seeking to solidify its position across consumer and enterprise segments. Google countered with the release of Gemini 3.1 Flash Lite, a significantly more affordable variant priced at roughly one-eighth the cost of its Pro tier. The move signals Google's aggressive pricing strategy to capture market share from competing AI providers. Meanwhile, developments around the Department of War's engagement with Anthropic highlight growing government interest in AI capabilities and the geopolitical dimensions of AI supply chain decisions.
