Job ID: 38715225

Budget: ₹37,500 – ₹75,000 INR

I have a software and there are several settings, and some settings can be tweaked or implemented in a particular way, and if client requirements are completely not achievable by either settings or smart way of implementing one or more thanone settings mix, customizations are suggested. clients email me, and i respond them, and there can be further few back and forth with clients before i won the projects. i need all my hundreds of email threads to be used to train my custom gpt, and overtime the custom gpt is then used by my sales team or myself, where i paste the client email content, and in response whole reply is ready. and when client replies me further, i go to our developed website, find the thread, and paste new client email content there, and it again gives me fine reply. when it gives reply, i approve, or modify and approve, and based on this also gpt is trained.
When you give me proposal, give me, techstack you will use, USD that will cost for hosting in first 3months while gpt is trained, and after that what hosting every month. also give me what you will use, openai, or meta's ai which is opensource and what all, and

your proposal should contain 1 milestone which is 100% milestone, 100% upon completion and training of my 100 email threads (and all back and forth conversation in those email threads.) used to train,and we generate successful 20 replies on first inquiry, and 2 to 4 back and forth on any 10 of the 20 new inquiries as test. why i need 1 milestone, because if someone leaves my project even by leaving 0.5% incomplete, total is crap for me as anyone else will not be liking to complete someone's else incomplete work
