10 Secrets That Make OpenAI Unique
The company that killed the “Google Search” monopoly in 60 days.
The Origin Code (2015)
The Context: Google had just bought DeepMind. Elon Musk and Sam Altman were terrified that Google would monopolize AI and potentially harm humanity.
The Idea: They founded OpenAI as a Non-Profit to build “Safe AGI” (Artificial General Intelligence) and open-source it to the world. They raised $1 Billion in donations to hire the best scientists away from Google.
ChatGPT (Nov 2022): OpenAI released a simple chat interface for their GPT-3.5 model as a “low key research preview”. It reached 100 million users in 2 months, becoming the fastest-growing app in human history.
OpenAI started as a non-profit but pivoted to a “Capped Profit” model to pay for the massive compute costs. At ativesite.com, we analyze the RLHF tech that makes it feel human.

Public Benefit Constitutional AI. |
| Accessibility | API First Standard for devs. |
Ecosystem Inside Workspace. |
Enterprise Focus on safety. |
The Challenger: Anthropic
Why watch this portal? Founded by ex-OpenAI researchers (Dario Amodei) who left because they thought OpenAI was moving too fast and ignoring safety. Their AI, Claude, uses “Constitutional AI” to self-correct based on a written constitution rather than human feedback.
It feels more natural and less “robotic” than GPT. It is the hipster choice for AI power users.
The 10 Technical Secrets
1. The Transformer Architecture
GPT stands for “Generative Pre-trained Transformer”. Ironically, this architecture was invented by Google in 2017. OpenAI was just the first to realize that if you scale it up to massive size (Billions of parameters), it starts to show “Emergent Properties” like reasoning.
2. RLHF (Reinforcement Learning from Human Feedback)
Raw GPT-3 was rude and hallucinated wildly. To fix this, OpenAI hired humans to rate thousands of answers (Thumbs Up/Down). They trained a second AI to predict what humans like. This “Preference Model” tamed the beast.
3. The Microsoft Supercomputer
You can’t train GPT-4 on a normal cloud. Microsoft built a bespoke supercomputer in Azure just for OpenAI, linking 10,000+ A100 GPUs with high-speed InfiniBand networking. It cost hundreds of millions of dollars.
4. Mixture of Experts (MoE)
Rumors suggest GPT-4 isn’t one giant model. It’s likely a Mixture of Experts—say, 8 smaller models (one expert at code, one at creative writing, etc.). A “Router” decides which expert answers your prompt. This makes it faster and cheaper to run.
5. Tokenization (Tiktoken)
AI doesn’t read words; it reads “Tokens” (chunks of characters). OpenAI wrote a custom tokenizer called Tiktoken that is highly efficient at compressing text into numbers, saving money on API calls.
6. The Knowledge Cutoff
GPT is trained on a snapshot of the internet. It doesn’t know today’s news because “training” takes months and costs millions. It is a frozen genius, not a search engine (until integrated with Bing).
7. Plugins & Actions
To solve the static data problem, OpenAI created a standard for “Plugins”. This turns ChatGPT into an Operating System that can call other apps (Expedia, Wolfram) to do things in the real world.
8. Whisper (Speech)
OpenAI open-sourced Whisper, a speech-to-text model trained on 680,000 hours of audio. It is so good it killed the transcription startup industry overnight. It powers the “Talk to ChatGPT” feature.
9. Red Teaming
Before releasing GPT-4, OpenAI spent 6 months “Red Teaming”. They hired experts to try to make the AI do bad things (make bombs, write hate speech) so they could patch the holes before the public saw it.
10. Q* (Q-Star)
The rumored secret project. It is speculated to be a breakthrough in “reasoning” using tree-of-thought search (like AlphaGo) combined with LLMs. It might be the key to AGI (Artificial General Intelligence) that can solve math and code perfectly.
Frequently Asked Questions
Is ChatGPT free?
GPT-3.5 is free. GPT-4 (the smart version) costs $20/month. The free version costs OpenAI millions per day in server bills, subsidized by Microsoft.
Does OpenAI steal data?
They scraped the public internet (Common Crawl) to train the model. This is a legal grey area (Fair Use vs Copyright) currently being fought in courts by NY Times and authors.
Who owns OpenAI?
It’s complicated. A non-profit board controls a “Capped Profit” subsidiary. Microsoft invested $13B but doesn’t have board control (technically). It is a unique corporate structure designed to prevent shareholder greed.
