Tired of cheap yes-men posing as "AI experts" on Upwork? Artificial Intelligence has been the subject of a lot of hype lately That led many failed developers to brand themselves as AI specialists in an attempt to scrape the bottom of Upwork projects. They learned a thing or two about Chat GPT and promise to code you the best and greatest AI model for just $500. Sounds too good to be true, huh? We're literally talking about the cutting edge of tech here... Well, in fact, it is. And allow me to let you in on a little secret since you’ve read so far… Open AI’s Chat GPT is just the tip of the iceberg when it comes to AI tech. Yes, it's smart, and you've been seeing it all over LinkedIn, but it's API is rather weak. It’s great when answering general questions, and can sometimes be fine-tuned for more specific knowledge. But a lot of times it feels like trying to fit a square peg in a round hole. And for AI projects related to computer vision or audio, GPT plainly cannot be used. The reality is that to get good results, a lot of times a custom AI model will need to be trained. That’s where I come in with 4 years of experience in AI and 20+ projects completed. I’ll be able to consult you on your project, figure out the best approach, and deliver with the highest quality. Besides being top rated plus here on Upwork, I also was rated "Top AI Developer” by three independent companies: Clutch, AppFutura and GoodFirms. 𝗦𝗲𝗻𝗱 𝗺𝗲 𝗮 𝗺𝗲𝘀𝘀𝗮𝗴𝗲 𝗻𝗼𝘄 𝘁𝗼 𝗱𝗶𝘀𝗰𝘂𝘀𝘀 𝘆𝗼𝘂𝗿 𝗽𝗿𝗼𝗷𝗲𝗰𝘁! Update 10/01/2023: Due to the very high demand for AI experts, I am able to work on a limited amount of projects every month and are prioritising clients with extensive business experience or proven business modelsweb3.js
