That's a great question. While both are powerful language models, VertexGenBot is built for multimodal tasks within Telegram. The key differences are:

1. File Analysis: You can directly upload PDFs, audio, video, and other files for analysis, which is something most standard chatbots can't do.
2. Video Generation: We integrate VEO-3 technology, allowing you to create video from text.
3. Integrated Workflow: Everything happens in one place. You don't need to switch between a browser and different apps. Think of it as a powerful AI toolkit, not just a chatbot.

No, your history is safe! The bot saves your conversations independently. To see them, just use the /my_chats command. You can view all your past chats and switch back to any of them to continue where you left off.

Think of them as different engines for different jobs:

• ⚡️ Flash Models are optimized for speed. They're perfect for quick questions, simple summaries, and everyday tasks where a fast response is more important than deep analysis.
• 🚀 Pro Models (VIP) are our most powerful and intelligent engines. Use them for complex tasks like writing code, in-depth document analysis, or high-quality creative writing where you need the best possible result.

You have two great options:

1. For a soft reset: Use the /start command. This resets the AI's immediate memory for the current chat but keeps your history intact. It's the best first step for any strange behavior.
2. For a hard reset: Use the /new_chat command. This archives your current conversation and starts a brand new one, ensuring there's no context bleed-over from previous topics.

Absolutely! You can use VertexGenBot on any device that has Telegram, including the Telegram Desktop app for Windows, macOS, and Linux. The functionality is identical, and it's often easier to work with files and copy-paste long texts on a computer.

Sorry to hear you're facing an issue. Usually, the upgrade is instant. Please try a quick /start command to refresh your bot session. If your status still doesn't show as VIP in the /my_stats command after a few minutes, please contact our support team directly with your Telegram User ID (from /my_stats) and we'll resolve it immediately.

Once you hit the daily token limit on the Free plan, you have a few options:

1. Wait: The limit resets automatically at midnight (UTC).
2. Upgrade: The /vip command gives you a much larger daily limit and access to all features.
3. Buy a Package: Use the /buy command to purchase smaller, specific packages (like for video or image generations) if you don't need a full subscription.

You will never lose your chat history. When your VIP subscription expires, your account will automatically revert to the Free plan. You'll still have access to all your conversations via /my_chats. You'll simply be subject to the daily limits and feature restrictions of the Free plan until you decide to subscribe again.

As stated in our Terms of Service, we do not offer refunds. This is because we incur immediate, non-refundable costs for every request you make to the AI models. We encourage you to use the Free plan extensively to evaluate the bot's capabilities before purchasing a VIP subscription.

The /my_stats command is your personal dashboard. It provides a detailed breakdown of all your monthly free usage limits (for images, video, web search, etc.) and shows how many you've used versus how many you have remaining.

That's an excellent question. Generating video from a text prompt is an incredibly complex computational task. It involves interpreting your text, creating a sequence of consistent images, animating them, and rendering a final video file. This process requires a massive amount of processing power, which is why it takes significantly longer than generating text or a static image.

This can happen for a few reasons. AI video generation is still a new technology. For best results:

1. Be Specific & Detailed: Instead of a man walking, try a cinematic shot of a man in a trench coat walking down a rainy, neon-lit street at night.
2. Use English: The models are primarily trained on English, so prompts in English currently yield the most accurate results.
3. Focus on Visuals: Describe camera angles, lighting, and style (e.g., anime style, hyperrealistic, shot on 35mm film).

The most common reason for this is that the PDF is a scanned image rather than a text-based document. The AI can only analyze files that contain actual text data. If you scanned a paper document, it's essentially a photo. To fix this, you would need to use an OCR (Optical Character Recognition) tool to convert the scanned image into text before sending it to the bot.

You can do that! When you first send the YouTube link, the bot will ask what you want to do. Choose the "Analyze Clip" option. It will then prompt you to enter a time range in the format MM:SS-MM:SS (for example, 05:10-07:45). All subsequent questions will then focus only on that specific segment of the video.

This is a key aspect of how current multimodal AI works. The AI processes the image and your text in a single turn. It doesn't "remember" seeing the image in the next turn unless you send it again. To ask follow-up questions, you have two options:

1. Provide all your questions in the same message as the image.
2. Use the image analysis mode, which keeps the image in context while you ask questions.

That's the art of prompt engineering! To level up your images, add these elements to your prompts:

• Style: digital art, photorealistic, impressionist painting, cyberpunk, steampunk.
• Composition: close-up shot, wide angle, portrait, from a low angle.
• Lighting: cinematic lighting, soft light, neon glow, dramatic lighting.
• Details & Quality: hyperdetailed, 8k, insanely detailed, sharp focus.
• Example: Instead of a cat, try Photorealistic close-up shot of a fluffy calico cat, cinematic lighting, soft focus background, hyperdetailed, 8k.

You can use a technique called "role-playing." Start your very first prompt in a /new_chat with instructions about its persona. For example:
"You are Captain Jack, a witty and adventurous pirate. Your tone is always slightly sarcastic and you use pirate slang. Your first task is to explain quantum computing."
The bot will then maintain that persona for the rest of the conversation.

You can specify the desired length and format directly in your prompt. Try adding phrases like:

• "...explain this in three sentences."
• "...summarize this into a 5-point bullet list."
• "...answer with a single paragraph."
• "...give me a very brief, one-sentence explanation."

Currently, the AI processes one primary task per turn. Chaining commands like that can confuse it. The best practice is to do it in two steps:

1. Send the PDF and ask: "Summarize this file."
2. Once you get the summary, copy a key phrase from it and start a /image generation with a prompt like: "Create an image based on this concept: [paste key phrase here]."

While we strive for 100% uptime, slowness can occur due to high load on the AI provider's servers. First, please check our official support channel for any announcements about maintenance. If there are no announcements, a simple /start command will often fix the issue by refreshing your connection.

This is a limitation of the Telegram platform itself. For security and performance reasons, inline buttons on messages expire after a certain amount of time. Unfortunately, we cannot change this. You can always re-run the original command to generate a new message with fresh buttons.

This can sometimes happen if a previous conversation in your chat history was in Russian. The AI might get "stuck" on that context. The quickest fix is to use the /new_chat command to start fresh. You can also set your preferred language permanently with the /lang command.

The AI models have a built-in safety filter that can sometimes be oversensitive. It might misinterpret certain words or phrases. Please try rephrasing your prompt using different terminology. If you believe your prompt was blocked in error, please let our support team know so we can investigate.
