What Is LibreChat AI?
-> LibreChat is a free and open-source AI chat platform that allows you to access and manage various AI models from different providers in a single, unified interface. It brings together major AI providers like OpenAI, Anthropic, Google, and others, allowing you to switch between them seamlessly. Meaning, kung meron kayong API from OpenAI, Anthropic, Gemini, etc., pwede nyong ibala sa LibreChat AI.
Use Case?
-> For personal use. Pero pwede nyong i-benta or ipa-rent sa iba. Pwede ring pang-share lang for free.
What You Need
- Credit / Debit Card. Kung may working BIN kayo, mas OK para hindi nyo na i-shoulder ang deposit. Kung wala naman, you can use your own credit or debit card, make sure lang na merong laman at least $10 kasi may deposit nang requirement na naka-depende sa bank. Prepaid Debit Cards are not acceptable sa Google Cloud Console.
- VPN. Kailangan lang ito in case meron kayong gagamiting BIN at hindi owned credit/debit card.
- Own/Custom Domain. Optional lang ito, pero mas prefer ko ito for VM-security purposes.
- Utak. Mahalaga talaga ito. Hindi nyo masusundan ang instructions kung wala kayo nito.
- Go to You do not have permission to view the full content of this post. Log in or register now. and sign up for a free account. May $300 credits yan na valid for 90 days for new sign ups. Again, need ng deposit depende sa bank ng card mo. Sa mga na-try ko na, pinaka-mababa ang BDO credit card. Nasa ₱300 lang yung deposit.

QUICK TIP
For a more personalized AI model configurations, aralin nyo yung configuration ng "librechat.yaml". May sample naman sa official repository. Read You do not have permission to view the full content of this post. Log in or register now. para sa detalye.
Ginawa ko ang tutorial na ito para magka-idea yung mga salahula diyan, para maisip (in case kaya nilang i-perceive) na hindi simpleng one-click button ang pag-deploy ng LibreChat. Para sana, hopefully, maisip nilang makapal ang mukha nila dahil yung mga simpleng rules and instructions lang ay hindi pa nila magawa. Yung iba pa diyan, makahinge ng API key na akala mo naman nadadampot lang yan sa tabi-tabi. Eeh kung gumawa ka ng GCP account para ma-activate ang $300 credits, edi may API key ka na rin sana. Hindi yung sa hinge hinge na lang aasa. Abah, mahiya naman kayo.
