What Is OpenAI?

At this point, everyone has heard of OpenAI. OpenAI is a leading research lab in the US that focuses on machine learning, deep learning, robotics, and computer vision. 

But its main job is developing AI models, of which ChatGPT (generative pre-trained transformer) is the most well-known.

OpenAI also offers DALL·E, Sora, and Codex, which are used in everything from image and video generation to software development.

Here’s a quick breakdown of what OpenAI does:

✅ OpenAI’s models help users with writing, coding tasks, image generation, speech recognition, and more

✅ ChatGPT is integrated into Microsoft products, enterprise workflows, and creative industries

✅ Organizations are using the AI platform to automate business operations and improve customer success rates

OpenAI Features

“Help me process this email” or “Help me summarize this document”—OpenAI CEO Sam Altman uses AI daily for ‘boring’ tasks, but the tech itself is anything but boring.

Here’s a list of OpenAI’s most impressive features:

Feature #1: AI that listens—and responds like a human

OpenAI’s latest models, like GPT-4o, can process speech and text in real time, mimicking human-like conversation with near-zero latency. It’s so good that Microsoft and other enterprise giants are using it to power AI assistants, customer support bots, and even meeting transcription tools.

Feature #2: Smarter AI, cheaper costs

OpenAI introduced prompt caching and model distillation, cutting API costs for businesses by up to 50%. This means AI-powered apps don’t have to pay full price for repetitive prompts.

Feature #3: A true multimodal powerhouse

GPT-4o now sees, hears, and speaks—meaning it can interpret images, understand videos, and generate audio in real time. Developers are using this to create AI-powered tutors, coding assistants, and even smart surveillance tools.

Feature #4: AI that remembers, learns, and adapts

Unlike other AI models that treat every prompt like a first-time meeting, OpenAI’s memory feature lets AI retain context over multiple conversations. This means that it’s remembering your writing style or your last customer complaint for a more personalized experience.

OpenAI pricing

  • Free Tier
  • ChatGPT Plus: $20/month per user
  • ChatGPT Team: $30/month per user
  • ChatGPT Enterprise: Custom pricing 

📮 ClickUp Insight: Your employees lack context

According to ClickUp’s research, the average knowledge worker sends about 25 messages a day just trying to track down information and context.

That’s a lot of time lost scrolling through endless emails, chats, and scattered conversations. If only there were a smarter way to keep everything—tasks, projects, messages, and emails—connected (with AI, of course). Well, there is: Try ClickUp!

DeepSeek Vs. OpenAI on Reddit

When it comes to AI models, few places offer as much unfiltered honesty as Reddit. 

OpenAI, specifically ChatGPT, has been the dominant force in the AI space, but DeepSeek is generating serious buzz, especially among developers and those seeking affordable API alternatives. 

Based on Reddit discussions, here’s what users have to say.

For many, the experience with DeepSeek felt smooth, powerful, and responsive, especially in coding workflows.

A post by u/klippers in r/LocalLLaMA sparked massive discussion:

I spent most of yesterday just working with deep-seek working through programming problems via Open Hands (previously known as Open Devin). And the model is absolutely Rock solid.

Another fact to note: AI can be expensive, especially when using APIs for large-scale tasks. OpenAI’s pricing has frustrated many, and DeepSeek’s affordability has been a breath of fresh air, as per users. 

I uploaded $2 and made over 400 requests. I still have $1.50 left apparently.

However, the biggest complaint is inconsistency. As one Redditor pointed out:

DeepSeek gets stuck in a loop at times, ignores my prompts, and says nonsensical things. Maybe it was fine-tuned for coding and other benchmarks? Looks like coders are raving about this model, but for normal stuff—common sense, reasoning, etc.—it just seems a step below the top models.

Meanwhile, OpenAI has been a dominant force in the AI industry with its GPT models, which are reflected in user experiences. And this one Reddit post really captures it best:

Oh ChatGPT, let me count the amazing things you do for me…planning corporate events, brainstorming topics, meeting summaries, outlines for white papers, regular expressions, MBOs , writing SQL…figuring out what to make for dinner, writing silly stories for my kids, it just goes on and on. Couldn’t imagine not having it at this point.

However, for programmers, OpenAI’s GPT models have also received mixed reviews. Some developers claim it has declined in accuracy, while others still prefer it over alternatives.

Also it feels very poor for programming, even if I use something like Github Copilot or Microsoft Copilot Pro, GPT-4T still feels worse for programming than Claude 3 Opus or Claude 3.5 Sonnet.

💡 Pro Tip: AI writing tools are only as good as the prompts they receive—master AI writing prompts with this guide to create relevant, engaging, and marketing-ready content.
