GPT-6 Sol Becomes Default Light Model in Perplexity Computer

OpenAI's GPT-6 Sol is now the model behind the Light setting in Computer, Perplexity's product that works through tasks for its users. Perplexity says GPT-6 Sol is available in both Perplexity and Computer, and that it is now the default Light option in Computer's effort selector. Perplexity introduced those effort presets days earlier; each one combines an orchestrator model, the model that directs the work, with a reasoning depth, to control how deeply and efficiently Computer works through a task. Changing the default for Light changes which model runs the job for anyone who picks that preset.

The post gives no reason for the choice, no benchmark, and does not name the model Sol replaced. Separate evidence from the same day suggests one possible reason, cost: Artificial Analysis reported that GPT-6 Sol and Luna halve the cost of their predecessors with similar scores on its Intelligence Index, mostly through a roughly 50% cut in token pricing. That is consistent with putting Sol in a low-effort slot, though Perplexity did not cite it, and how Sol performs inside Computer specifically is not measured here.
