๐จChatGPT has a feature called "Sites."
99% of users don't know it exists.
It's quietly becoming one of the most useful features in ChatGPT.
Here's how it worksโand 7 practical ways to use it: ๐๐
Sam Altman, CEO of OpenAI:
โYou donโt need to write prompts anymore.โ
In a 38-minute session with Stanford students, he breaks down how to use ChatGPT far beyond the basic prompts most people rely on.
A friend sent me the recording last night, so I decided to watch the entire thing.
Honestly, it made me realize I was probably using only a small fraction of what ChatGPT is actually capable of.
Watch the full talk.
Then check the guide below to learn how to build a system that can prompt itself.

21 of the 52 official Claude Code prompts don't involve writing any code.
They're sitting in Anthropic's own docs. Almost nobody clicks through.
One of them is written from a PM's point of view, word for word: "I am a PM. Walk me through what happens when a user clicks Export to PDF, from the UI down to the result."
Another reads an ad-performance CSV, finds the underperforming headlines, and generates 20 new variations that stay under 90 characters.
Another turns meeting notes into Linear tickets with acceptance criteria attached.
The name is doing the damage. "Code" filters out every single person who'd get the most out of it on day one.
What it actually is: an agent with a terminal, file access, and the patience to read every file in a folder before it answers you. The folder doesn't have to be a repo. Point it at contracts, transcripts, exports, a pile of PDFs nobody's opened since March. The prompts hold.
And the engineering ones are sharper than what most people are typing:
โ "what would break if I deleted the retryWithBackoff helper?"
โ "review my uncommitted changes and flag anything that looks risky before I commit"
โ "the checkout endpoint started returning 500s an hour ago. check the logs, recent deploys, and config changes, then tell me the most likely cause"
That last one is a full incident triage in one sentence.
43 of the 52 ship with the example values already filled in. You're not writing prompts. You're swapping filenames.
The best thing Anthropic has published this year is a page in the docs with no link on the homepage.

The cost of building with AI keeps getting lower.
Three stages separate someone who writes a good prompt from someone who builds a system that actually works in production, and most people stop at the first one.
Prompt engineering is a single shot: a system prompt and a user message go into the context window, the LLM processes it once, and an assistant message comes back. Nothing gets curated. Nothing loops. It works until the task needs information or judgment the prompt itself cannot hold.
Context engineering adds a step before the model ever runs: curation. Docs, tools, memory files, instructions, domain knowledge, and message history all exist as candidates, and only some of them make it into the actual context window the LLM sees. The model can now return a tool call instead of just an answer, and the tool result feeds back into that same pool of candidate context for next time. The skill here is not writing a better prompt. It is deciding what does not belong in the window.
Harness engineering turns that single curated call into a loop. The LLM checks whether it is done. If yes, it returns the final answer. If no, it makes a tool call against real tools and environment, search, code execution, bash, file I/O, web, APIs, gets a result back, curates that result into the message history, and runs again. Long-term memory sits alongside the whole loop, feeding it and getting fed by it. The loop keeps running until the task is actually finished, not until the first response comes back.
Each stage did not replace the one before it. Harness engineering still needs curated context, and curated context still needs a well-written prompt underneath it. The difference is what gets added on top.
Bookmark this before you call prompt engineering the whole job.
CLAUDE'S NEWEST MODEL JUST BUILT A FULL BRAND WEBSITE AND IT LOOKS LIKE A $15K AGENCY JOB
No designer, no copywriter, no dev team. One product photo in, a full branded site out.
This is Claude Fable 5, and it didn't just slap text on a template. It built an entire story around the product:
a "What's Inside" section breaking down every ingredient a "Why The Jar Matters" section that sells the packaging itself real product photography placed like a real brand shoot smooth scroll animations tying every section together
Nobody wrote this copy by hand. Nobody picked these colors in Figma. One model looked at a product and built the entire site, section by section, like it already knew what a $15k brand launch looks like.
This is the model most people haven't even touched yet, while it's already outputting work agencies charge real money for.
the founders using Fable 5 for their launch pages right now are skipping the entire design phase everyone else still pays for.
Andrew Ng just released a free 2-hour course on complete Harness Engineering
How to go from one prompt to a reliable system of agents that can run, test, and improve themselves:
09:14 - Build your first agent from scratch
33:11 - Master agent loops
1:02:46 - Turn loops into reliable workflows
1:30:15 - Build agents that improve their own work
1:49:05 - Run the complete system without supervision
Model โ Harness โ Reliable Software
Most agent tutorials stop once the model can call a tool
This one shows you how to build the infrastructure around it within the first 20 minutes
Most people are still prompting one agent at a time
Andrew Ng is already teaching the layer above:
Harnesses that give agents context, tools, tests, and feedback
Watch this brilliant course and build the harness

A TRADING FLOOR DOES NOT GRADE A BOOK BY ITS EQUITY CURVE, AND THE NUMBER IT GRADES BY IS THE ONE RETAIL NEVER PULLS UP
The blotter gets one grade.
PF = sum of wins / sum of |losses|
Add every winning fill, add every losing fill, divide. No story survives that division and no screenshot argues with it.
Strip the math away. Winners averaging 1.8% against losers averaging 1.2% put the book near 1.5, and desks start asking questions anywhere under 1.25.
On screen 400 fills build the cloud dot by dot, losers clustered at short holds, winners stretched out long. The equity curve hides that shape completely.
Minara dragged this off the trading floor. Type the idea in plain English and it picks the factors, writes the Python, and hands you the backtest with Sharpe and drawdown in the open.

I found an interesting way to avoid making a single model do all the coding work
fable-orchestrator โ โ 525
Itโs a skill for Codex that splits the task into three roles:
โธ Fable plans the work and makes the final decision
โธ GPT-5.6 Luna writes the standard implementation
โธ DeepSeek V4 Flash handles repetitive iterations and bulky loops
The logic works like this:
task โ plan from Fable โ several limited sub-tasks โ parallel implementation โ result verification โ final evaluation
โ the powerful model doesn't waste context on every minor tweak
โ fast models handle the straightforward parts of the work
โ Codex retains the role of a runtime that gathers evidence and verifies the code
The most interesting thing here isn't the specific models, but the architecture itself: first separating responsibilities, then assigning only limited tasks to the agents
Important note: this isn't a ready-made "one-click" multi-agent program. The repository requires a pre-configured Codex Router, OpenCode Go agents, and a local `Fable` alias. There are no independent quality benchmarks in the repository yet

ANTHROPIC JUST OPEN SOURCED THE ENTIRE WALL STREET WORKFLOW AND FIRMS ARE NOT GOING TO BE HAPPY ABOUT IT.
DCF models. LBO models. Equity research reports. Merger analysis. KYC checks.
All of it. Free. On GitHub.
Here is what just became available to anyone with a laptop.
Direct connections to Bloomberg, FactSet, S&P Global, Morningstar, and PitchBook.
Real Excel models with live formulas and sensitivity tables built automatically.
CIMs, IC memos, earnings reports, and buyer lists drafted on demand.
PE due diligence, GL reconciliation, and NAV tie-outs running as production agents.
This is not a chatbot wrapper that summarizes financial news.
These are production agents that own entire financial workflows end to end.
The kind that investment banks and private equity firms pay $50,000 to $500,000 per year in software licenses to run.
Now it is a one-line Claude Code plugin install.
19,800 GitHub stars.
Apache 2.0 license.
100% open source.
Think about what this actually means.
A junior analyst at a bulge bracket bank spends 80% of their 100-hour week running models, drafting memos, and compiling data across Bloomberg and FactSet.
That entire workflow just became a Claude Code agent.
The banks charging clients $500 an hour for analysis that this system produces in minutes are not going to tell you this exists.
The boutique advisory firms charging $50,000 retainers for due diligence work that these agents handle autonomously are not going to promote this repo.
But it is already live.
19,800 people have already starred it.
The window where knowing this gives you an edge over every analyst, associate, and advisor still doing this manually is open right now.
Star it. Fork it. Deploy it this weekend.
Bookmark this before your next financial model.
