In 2025, the AI strategy shifted from searching for a single best large language model to assembling specialized stacks tailored to specific tasks such as coding, agentic workflows, chatbots, creative writing, and scientific research. Leading models in each category include Claude Opus 4.5 for coding, OpenAI’s GPT-5.2 for agentic tasks and chatbots, Alibaba's Qwen series for value and multilingual applications, and Sudowrite’s Muse for fiction writing. The emergence of uncensored local models like Dolphin highlights niches demanding minimal restrictions, while open-source models provide customizable, cost-effective alternatives for business and research.
