codexers - one job. one post. seven days. 1. Go to Community and click New post. 2. Select the Proof Receipts category. 3. Put this in the headline: MY PROOF RECEIPT 4. Copy this into the body and replace the brackets: JOB [Every ___, I need to ___ so that ___.] BASELINE [Right now this takes ___ / causes ___ errors / needs ___ rework. Source: MEASURED or ESTIMATE.] SMALLEST CHANGE [ChatGPT may ___. A human must still check or approve ___.] EVIDENCE I’LL CAPTURE [I’ll capture ___ before and ___ after, with private details removed.] 5. Here’s a completed example. These are example numbers, not a member result: JOB Every Friday, I turn scattered project notes into a client update so the client knows what happened and what comes next. BASELINE ESTIMATE: about 45 minutes and usually one rewrite because I miss a decision or next step. SMALLEST CHANGE ChatGPT may turn sanitized notes into a first draft with progress, blockers and next actions. I still check every fact and approve anything before it is sent. EVIDENCE I’LL CAPTURE A timer, the sanitized notes, ChatGPT’s draft, my final version and the number of corrections I made. 6. Post it. 7. Take a screenshot of your Proof Receipt. 8. Drag the screenshot into the ChatGPT app. 9. Put this in the prompt box: Help me build this. 10. Let it cook. Then use ChatGPT Voice in the same conversation and say: Ask me one question at a time. Help me find the smallest useful test I can run in seven days. Keep anything involving people, money, trust or publishing behind a human approval gate. Stop when I have one next action. 11. Return to your Proof Receipt post and leave this as your first comment: NEXT ACTION [The next thing I’m going to do is ___.] BY DAY 7 [When this challenge is finished, I want to have ___.] 12. Keep returning to the comments on the same post: UPDATE WHAT I TRIED: WHAT HAPPENED: WHAT I LEARNED: NEXT ACTION: 13. On day seven, compare what you planned with what you actually created. Leave this final reply:

Codexers, idk about you but gpt-5.6 is blasting through my ChatGPT subscription like there's no tomorrow. so i just created this video. in it i go over: - why my token usage instantly 2x'ed with GPT-5.6 and why i keep hitting rate limits - how there are now 15(!) different model options to choose from - the system i created to stop wasting tokens tldr: CAPS (Codex Agent Productivity System) picks the right model (Sol, Terra, Luna) at the right reasoning level (Light, Medium, High, Extra High, Ultra) for the right job. it basically means you don't accidentally burn through your chatgpt sub picking the wrong model for the wrong job. my suggestion: 1. put me on 2x and watch the Loom below in 5 mins 2. enter this prompt into Codex/ChatGPT: "inspect this repo: github.com/lennoxsaint/caps-productivity-kit then tell me in simple terms what it does, how we can use it to not waste my chatgpt subscription's usage limits and what the next step to install it is." bonus: - if you wanna go deeper on the difference between Sol, Terra and Luna check out this article i published on X yesterday

so Codex has just been merged into the ChatGPT desktop app. this is WILD news. Codex had 5M+ users. ChatGPT (across web and desktop) has 1B+ users! i suspect this means one thing for Codex Club: we're about to get a lot more popular :D remember who we are Codexers; the first 131 of Codex Club!

welcome to the practical corner of ChatGPT. Codex Club is for non-technical founders, service operators, freelancers, consultants, and creators who want AI to do real business jobs — not just make impressive-looking drafts. the weekly rhythm is simple: 1. bring one real business job. 2. do the current Weekly Build Challenge. 3. post one proof receipt. 4. choose one measured next step. Your first move: open the current Weekly Build Challenge in Classroom and post the proof prompt shown there. your first proof can be rough. it cannot be vague. new here? reply with: 1. the business job you want AI to perform. 2. the current baseline. 3. the receipt that would prove it worked. let's fucking build. with receipts.
