Perplexity cuts reasoning costs with Chinese open-source model, claims Claude Opus-level performance at one-third the cost

Perplexity released a research preview of a model it post-trained from Chinese open-source AI model GLM 5.2 for its agent system. It said the model delivers performance comparable to Anthropic\'s Claude Opus 4.8 at about one-third of the cost, routing most tasks to GLM 5.2 and sending only difficult ones to Opus 4.8. The company said the approach reduced costs versus using Opus for all tasks.
