Pro

The DeepSeek Flash version is a distilled model optimized for low-latency scenarios, trading some complex reasoning capability for faster response speeds and lower token unit prices.

After a Plus user upgrades to Pro, the 5-hour limit disappears, the quota is restored to 5 times that of Plus, and one month is recalculated starting from the upgrade date.

Claude Duet is first available to Pro and Max users in the United States.

Anthropic's subscription plans (such as Pro and Max) usually provide a certain message/request quota per time window.

Claude Duet is currently in research preview, available to Pro and Max subscribers in the United States through a waitlist.

According to official information, Muse Spark Open is currently open to Max and Teams users, and Pro users will gradually gain access later.

The Pro, Max and Teams plans are all subscription-based, with users paying a fixed monthly or annual fee in exchange for quotas or feature access.

Based on Opus estimates, if you use it more than 4 days per month, subscribing to Pro ($20/month) is more cost-effective than pay-as-you-go.

The subscription model (Pro/Max) is a fixed monthly fee in exchange for a certain usage quota, after which you may be rate-limited or need to pay extra; pay-as-you-go is purely postpaid, with no monthly fee threshold but a higher unit price.

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.

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.

In v2.1.311, Pro and Max accounts skip two network requests when starting Claude Code within an hour of the last check, speeding up startup.
