We seek an expert 'Query prompt engineer/developer' to help create 4 queries to OpenAI GPT via an API, to produce results similar to ChatGPT. Each query will have a set of do's and don'ts expectations.This is NOT ChatGPT or Chat Completion. A query to OpenAI via API should get a similar result to chatGPT if the data, model, temperature, token size and expectations are exactly the same. The CEO is very knowledgeable about what a query to OpenAI via an API is and isn't able to do. There will be very little compromise on the quality of results expected. (There is always a way!) This test project assesses the candidates' capabilities and attitudes. We can discuss lots of long-term work for the right candidate based on their talent, availability and interest. We already have a technical solution integrating the CEOs local machine, Google Drive, various vectorDBs (which wont always be used), OpenAI and LangChain. ** Scope, Requirements and Expectations * 1] Help the CEO teach and create and write 4 specific queries to OpenAI GPT via an API, that is extremely similar to the desired results (produced via chatGPT) 2] Proactively work to figure out why something is working/not working 3] Work with our amazing developer to tweak/refine our current code and teach if necessary. 4] Record short video walkthrough of how code works * Deadline * One successful command prompt query per day. Must meet the desired results or CEO's expectations. GUARANTEED BONUS !

Although sometimes it is possible) 2 ] Help our main developer integrate any code developments into his application 3 ] Provide a short video walkthrough of the code, queries on how it works or can be adjusted if needed 4 ] Solutions MUST be able to do ALL the specific things discussed, agreed and shown possible.

Add a description of the work There are some special match (football, basketball, tennis... etc.) combinations that are released throughout the day by the owner of the betting website for their clients. I want to have a bot that bets on these special offers for the price that I set up as soon as they release those special combinations of matches (the bot shouldn't bet on the ones that have been already bet. Sometimes the amount that you can bet is limited so I would like to adjust the price myself. Also, The link of the website constantly changes and the previous ones become inaccessible. For example, "perfectlancer126.com" becomes "perfectlancer127.com" and goes on in a sequence like this. So, I want to set up the link in the bot so that whenever it is changed I can set up the new link and it can keep betting automatically.
