New: Important usage notes placeholder (keep)

Important Claude Usage Notes

📢 Important Information About Claude Usage Quotas

Since Claude officially calculates usage quotas based on Token consumption, and different models have different consumption weights,we havestrictly aligned with the billing policies of official subscription accounts. The specific consumption multipliers are as follows:

• Haiku model:1 use = 0.5× token consumption

• Sonnet model:1 use = 1× token consumption

• Sonnet + Thinking: 1 use = 1.5× token consumption

• Enable Research:1 use = 5× token consumption

• Opus model:1 use = 5× token consumption

• Opus + Thinking: 1 use = 7.5× token consumption

💡 Tips to save your quota:Our testing found that Sonnet delivers output quality comparable to Opus in most scenarios. We recommend choosing the flagship model first Sonnet For simple tasks, try Haiku—it saves quota and is highly efficient!

📌 Note:This multiplier is set tofollow the official policy. We recommend switching models flexibly based on your plan usage and actual needs in different scenarios

Our pricing advantage

Claude official has introduced a 5-hour limitin addition to the weekly limit, significantly reducing the amount available to subscription accounts each week

Even with the official weekly limit, ourregular plan prices are still half the cost of official self-top-ups, and yourtotal available usage is already 5 times that of an exclusive PRO account on the official website! An outstanding value.

For higher usage, we offer higher-usage plans and usage add-ons (valid indefinitely, stackable, and do not affect the remaining duration of your original subscription).

Note 4: About Thinking Mode

How to enable/disable Thinking Mode

⏱️ How to tell:When the clock icon button islit up, Thinking Mode is enabled; otherwise, it is disabled

🤔 What’s the difference between enabling and disabling it?

When enabled:Claude performs multiple rounds of reasoning and repeatedly verifies the task it is carrying out
In most cases:you don’t need to enable it—the results are the same either way
Recommended scenarios:Tasks that require careful reasoning, such as when code contains errors that require repeated analysis

⚠️ Note:Enabling Thinking Mode results in 1.5× token consumption, causing you to reach your usage limit sooner

Large screenshot placeholder

Image: Click the clock icon to enable/disable Thinking Mode

Other AI tools often have knowledge cutoffs that lag by months or even years, while Grok offers:

Zero-delay information access:Searches for the latest reports on events as they unfold
Instant financial market updates:Stock prices, exchange rates, and cryptocurrency prices refreshed by the second
Policies and regulations as soon as they are released:New regulations and executive orders available immediately after publication
Never miss scientific breakthroughs:Stay up to date with the latest papers, patents, and experimental results

Tutorial: Expert Mode & Deep Search

Core Features Tutorial

① How to Enable Expert Mode

Expert Mode enables Grok to providedeeper, more professional, and more detailedanswers, making it ideal for scenarios that require high-quality output (such as academic research, technical analysis, and business decision-making).

Above the conversation input box, find themodel selector(Usually displays the name of the model currently in use, such as "Grok 4").
Click the model selector, then select Expert Mode.
Once enabled, Grok will provide more technical details, supporting data, and multi-angle analysis in its answers.

💡 Tip:When asking a question, explicitly state requirements such as "I need a detailed technical analysis," and Grok will automatically match them with higher-quality output.

② How to use Deep Search

Deep Search is Grok's flagship feature, capable ofcross-validating multiple sources, conducting in-depth information mining, and automatically generating citations, making it particularly suitable for scenarios requiring high-quality information, such as academic research, industry analysis, and fact-checking.

Image: Deep Search interface.

How to enable

Enter your question in the input box.
Next tothe Send button(or below the input box), find the Deep Search toggle/button.
Click to enable it, and Grok will automatically enter Deep Search mode. The search process may take 10-30 seconds.
Once the search is complete, Grok will provide a detailed information summary and a complete list of sources.

Best practices for Deep Search

✅ Clearly specify your needs

For example: "Please conduct an in-depth search for global AI chip market share data in 2024 and provide authoritative sources"

✅ Specify a time range

Example: "Search for the latest developments in carbon neutrality policies from 2023 to 2024"

✅ Require multi-source verification

Example: "Please verify this data from three perspectives: academic papers, government reports, and industry analyses"

✅ Request complete citations

Example: "Please provide the full links and publication dates for all sources"

Helpful tip:Deep Search consumes more computing power and time, so it is recommended for situations that truly require in-depth information. For everyday conversations, you can use Standard Mode for faster responses.

New: Private Mode section

③ How to Enable Private Mode

Private Mode is Grok'scompletely anonymous conversation feature. Once enabled, your conversationswill not be saved, used to train models, or leave any trace. It is ideal for situations that require absolute confidentiality, such as handling sensitive information, trade secrets, and personal privacy.

Image: Click the ghost icon in the upper-right corner to enable Private Mode.

Enable from the chat interface

On the Grok main interface, click theghost icon in the upper-right corner
Click to enable it. The interface will display 🔒 Private Mode Active

Anticode Codex API Integration Guide

Connect Codex to the Anticode API service

Codex uses the anticode.cn API service provided by . Customers only need to create an Anticode API key first, then enter the API endpoint and key in the Codex configuration.

① Create an Anticode API Key

Open anticode.cn and sign in to your account.
Go to API Keys in the console, then click Create Key.
Enter any name, such as Codex.
For the group, select Codex or another Codex-enabled group authorized for the current account.

Note:If the token is created in an unauthorized group, you may see “Unauthorized to access this group” when making calls.

After creating a key, prioritize using the one-click configuration tool provided on the site. It automatically writes the Anticode API endpoint and your API key, making it suitable for beginners with the lowest error rate.

③ Enter these details when configuring manually

If you need to configure Codex manually, make sure the endpoint uses Anticode's OpenAI-compatible entry point:

~/.codex/config.toml

model_provider = "OpenAI"
model = "gpt-5.5"
model_reasoning_effort = "xhigh"
network_access = "enabled"
disable_response_storage = true

[model_providers.OpenAI]
name = "OpenAI"
base_url = "https://anticode.cn/v1"
wire_api = "responses"
requires_openai_auth = true

~/.codex/auth.json

{
  "OPENAI_API_KEY": "sk-your-Anticode-key"
}

OpenAI-compatible address:https://anticode.cn/v1
API Key:Enter the key generated in the anticode.cn console that starts with sk- .
Verification method:After saving the configuration, run codex in the terminal to start a simple conversation.

Codex vs. Other AI Comparison

ChatGPT FAQs (Try clicking One-Click Account Switch first)

ChatGPT Issue 1: Usage Limit

What should I do if ChatGPT says "The current account has reached its usage limit"?

💡 This means the current model has reached its usage limit (the official limit is 3 hours).

🔄 Two solutions:

Solution 1: Switch models

In the upper-left corner, switch models from the model selector(e.g., GPT-5 → GPT-4o) and continue asking questions on the current account.
