OpenAI released GPT-4.5 as a research preview, highlighting its deep world knowledge, improved understanding of user intent, and a 128,000 token context window. It is noted for excelling in writing, creative tasks, image understanding, and data extraction but is not a reasoning model. Microsoft unveiled Phi-4 Multimodal and Phi-4 Mini, open-source models integrating text, vision, and speech/audio, with strong performance in math and coding tasks.

Cohere released Command R7B Arabic, an open-weights model optimized for Arabic language capabilities targeting enterprises in the MENA region. The community is exploring the impact of larger models on creative writing, intent understanding, and world knowledge, with GPT-4.5 expected to be a basis for GPT-5.
