Dyan lang sa google search tip, marami kang maiipon na gpt4 cøøkíés pero tiis ka sa kakaintay ng turn mo. At least, legit yan na OpenAI API since ChatGPT playground ang gagamitin mo.
Doon naman sa mga kumakalat na mga ChatGPT UI (w/ possible GPT4 use) na no need for APIs, mas madalas ay reversed-engineered apis ang gamit galing sa providers ng gpt4 service like poe, forefront, phind, you, bing, atbp. Dyan medyo tumatagal, pero best is deploy your own. If you know how to run apps using codes sa github, search there using "free chatgpt", "gpt4-free", "gpt4free", "free gpt", etc.
Meron ka ng GPT4 server mo kahit in your own pc or a vps. Most of the time GPT4 still has limited access pero GPT3.5-turbo-xxxx mostly limitless. Kung may web-access yung UI, GPT3.5-turbo becomes GPT4-like. Malas lang kung mag-upgrade ng securities yung providers, but at least meron kang reserba. Bukod dyan, marami pang options using custom apis and endpoints, reverse proxy, UIs that prolong use of your OpenAI API, at meron din direct link for free GPT service, mga non-OpenAI GPT free service din na reliable for offline or online use, atbp. I'm just giving ideas para sa mga gusto talagang magkaroon ng free GPT on their own. You just need to start reading and applying the needed requirements. No pain, no gain. Mostly, ang mga usual na ginagamit ay nodes, git, docker and python tapos sundin nyo lang yung guide typing the provided scripts sa command line to run it. Kung nahihirapan kayo, find providers of custom reverse-engineered openai apis (or your own) w/ proxied openai endpoints with ChatGPT GUI installers that support it. Read between the lines na lang.
