Updates to Our Credit System and the New Ultra Plan 

Effective Date: September 24, 2025

As Sider's agent capabilities continue to expand, our AI agents have become increasingly powerful and resource-intensive. To keep performance fast and reliable for everyone, we’re refining how credits work and introducing a new Ultra Plan. 

1.New Credit System

Our most compute-heavy, multi-step agents now run on Elite Credits. This keeps their performance consistent as they get more powerful. 

Elite Credits for AI Agents  

Elite Credits now power our most resource-intensive features:

Deep Research

Scholar Deep Research

Web Creator

AI Slides

...and the many more powerful Agents to be launched

Advanced Credits for Models and Features  

Advanced Credits remain dedicated to our top-tier AI models and sophisticated features: 

Models (examples):

Advanced AI Models: GPT-5.5, Gemini 3.5 Flash, Claude Sonnet 4.6, Grok 4.3, Deepseek-V4-Pro, Kimi K2.5, Claude Opus 4.6 etc.

2.Support for Current Subscribers (no action needed)

To ease the transition, all existing paid subscribers receive monthly Elite Credits at no extra cost. Your current price and your Basic/Advanced credit amounts do not change.

Monthly Elite Credits by legacy plan:

Legacy Starter: 80 Elite Credits/mo

Legacy Pro: 120 Elite Credits/mo

Legacy Unlimited: 250 Elite Credits/mo

3.Introducing the Ultra Plan (maximum capacity)

For professionals who run heavy, agent-driven workflows, the new Ultra Plan offers our highest limits:

Basic Credits: Unlimited

Advanced Credits: 10,000 per month

Elite Credits: 2,500 per month

4.Updating Our Plan Lineup

We’re simplifying plans for new customers to Basic, Plus, and Ultra. The Starter, Pro, and Unlimited plans are now legacy and closed to new purchases.

Grandfathering: If you’re on a legacy Starter, Pro or Unlimited plan, you can keep using and renewing it as long as your subscription remains active. If you cancel or move to a new plan, you won’t be able to resubscribe to that legacy plan later.

Looking ahead

These changes ensure our agent features remain fast, reliable, and sustainable. Thank you for growing with us—this foundation allows us to build even more capable agents you can rely on.If you have any questions, please contact us at [email protected].
