Model credits and usage

Understand Design Plan credits, Top Model Credits, usage windows, and how to share your allowance across OpenDesign and other agents.

1. How credits are used and what happens when they run out

OpenDesign provides Design Plan credits and Top Model Credits. Go includes only Design Plan credits. Plus, Pro, and Max include bonus Design Plan credits alongside their Top Model Credits.

Models in the other model group draw directly from Top Model Credits. Design Plan models follow these rules:

Go

Go uses Design Plan credits only and has no additional Top Model Credits. After reaching a 5-hour or 7-day limit, wait for the corresponding window to reset.

Plus / Pro / Max

Design Plan bonus credits are used first. Once exhausted, further usage automatically draws from Top Model Credits. Requests stop when those credits also run out, unless auto-recharge is enabled.

Usage inside OpenDesign and through the OpenDesign API shares the same credits and usage windows. Drawing from existing plan credits is different from auto-recharge. Auto-recharge causes an actual payment and depends on whether you enabled it.

2. Credits by plan

The 7-day and 5-hour windows apply only to Design Plan credits. Top Model Credits are not subject to these two windows.

Model credits by plan
Plan Regular monthly price Monthly maximum Top Model CreditsNo 7-day or 5-hour limits Design Plan
Monthly maximum Maximum credits per 7-day window Maximum credits per 5-hour window
Go$10 $220 $0 $220 $55$18
Plus$20 $310 $20 $290Bonus $74No limit window
Pro$100 $480 $120Limited-time 20% bonus $360Bonus $90No limit window
Max$200 $900 $300Limited-time 50% bonus $600Bonus $150No limit window

Prices are regular monthly subscription prices, excluding introductory and annual discounts. Other amounts are model usage credits, not cash balances or fixed request counts. The 7-day and 5-hour limits apply only to Design Plan credits. Top Model Credits have no such windows and are granted and reset per billing cycle.

Design Plan models and credit multipliers

Credit multipliers vary by model as shown below. A lower multiplier uses fewer Design Plan credits for the same dollar value of model usage. These multipliers apply only to Design Plan credits.

DeepSeek V4.1 Flash has been upgraded to the October 17, 2026 update (1017).

Go includes Design Plan models but does not include image generation.

DeepSeek V4.1 Flash Eco may respond more slowly at times. Recommended for batch processing tasks.

3. Design Plan usage windows and resets

These windows apply only to Design Plan credits: Go has both 5-hour and 7-day windows; Plus, Pro, and Max have only a 7-day window. Top Model Credits have neither window and are granted and reset per billing cycle.

For new subscriptions, the 7-day window starts when the subscription begins and resets every 7 days.

Example: subscribe on Wednesday at 10:00 AM

Your 7-day window resets the following Wednesday at 10:00 AM, rather than on Monday or the first day of a calendar month.

5. Use credits in other agents with an OpenDesign API Key

Use an OpenDesign API Key to access OpenDesign models from agents including Codex, Claude Code, DSH, OpenCode, and Hermes. An API key connects your tool to the OpenDesign model service.

Use your API Key on other platforms to call Design Plan models and Top Models supported by your subscription. Design Plan models use Design Plan credits first, then any remaining Top Model Credits (Go has no Top Model Credits). Top Models use Top Model Credits directly. API and OpenDesign share the same credits; the maximum monthly total matches your plan card. Using external tools does not grant additional credits or reset usage windows.

The API supports OpenAI Chat Completions, OpenAI Responses, and Anthropic Messages. Other tools that support custom API endpoints and keys may also work; compatibility depends on testing.

An OpenDesign API Key is different from BYOK. The former uses OpenDesign credits; BYOK uses your own model provider key, with costs and allowances managed by that provider.
