Pro

Ultra and Pro are the two high-end tiers in Google's AI subscription system. Ultra is positioned as the top-tier option for heavy users, typically bundling the highest level of model access, larger usage quotas, and priority access to new features, at a price significantly higher than Pro; Pro is aimed at ordinary professional users, providing mainstream model capabilities and relatively generous quotas.

For tasks such as chatting, translation, summarization and batch text processing, Flash is recommended; for complex reasoning, long code, math problems and multi-step tasks, Pro is recommended, or the deep thinking mode should be enabled.

The solution uses an AI model as a judge to adjudicate gray-area assets that are difficult to determine, with Flash as the fast default option and Pro as the model with stronger reasoning capabilities.

The numbers 5x and 20x in the Max plan names indicate the multiplier relative to the base quota of the Pro plan.

Marqly's AI features — AI Assistant, AI Organizer, and MCP integration — are all included in the Pro paid version.

The core selling points of Perplexity's Pro and Max subscription plans are access to more powerful AI models and higher usage quotas.

For everyday use cases, a Flash model that can quickly and reliably solve a problem in one go is often more practically valuable than an expensive, slow Pro model that requires repeated calls.

Lightweight, high-speed Flash-type models are becoming the mainstream focus of attention, while expensive flagship Pro models have fallen into silence.

Model routing technology automatically assigns requests to different tiers of models based on the complexity of user input, routing simple questions through the Flash channel and automatically upgrading complex questions to the Pro channel.

The value of OpenAI's Pro subscription has just been halved, and the IPO discussion is wavering.

Perplexity's Pro and Max paid subscription users can use both Fable and Astra AI capabilities simultaneously in Computer mode.
