Next-Generation Foundation Models

GPT-5.5, released April 23, uses fewer tokens than GPT-5.4 to reach equivalent accuracy, reducing enterprise deployment costs. Claude Opus 4.7 (April 16) delivers a multimodal upgrade processing images up to 2,576 pixels for medical scans and schematics. Meta's Llama 4 Scout and Maverick (April 5, 2025) handle 10-million-token context windows for entire codebases or legal repositories. Google's TurboQuant (presented March 24, 2026 at ICLR) demonstrates a 6x reduction in KV cache memory using PolarQuant quantization, addressing long-context infrastructure bottlenecks. The capability gap between frontier and previous-generation models widened substantially in six months, while cost per capable-token declined systematically.
