RECENT EDITION VIEWS
What recent editions said about Models.
New models are aimed at narrow jobs: typed decisions, competition math, checking agent traces, world simulation and voice. Each is measured on its own terms.
October 12, 2026 edition: Models sector, 6 storiesNew models compete on cost per task and fit for a job, not just on headline capability. Examples include Sonnet 5.5's effort settings, d1's probability outputs, Kolibri-1's German focus and Solar Mini 4's long outputs.

Research
Microsoft Research and UIUC release StudentSim, per-student simulators for training AI tutors
StudentSim fine-tunes a small open model on each learner's de-identified records so it mimics both their answers and how they revise after a hint, giving AI tutors a more realistic practice partner than a frontier LLM role-playing a student.
Models
Meta releases Muse Wonder and Muse Wonder Full, its first frontier-class AI models
Meta's Muse Wonder is available through its API at $4/$20 per million tokens. The stronger Wonder Full is limited to Muse Code subscriptions.
