What they did
A developer built an app that takes any idea, researches it, checks feasibility and creates a working concept using several sub-agents, running cheaply on his own VPS with SearXNG search and Codex.
Result (as claimed)
Low-cost idea validation running on his server.
Tools they used
Cost: OpenAI Codex: free plan, paid from $8/mo. Checked 2026-10-14.
Set it up
Gather your sources
Collect the papers, notes, links or files you want to work from in one place.
Load them into the tool
Open OpenAI Codex, SearXNG and add your sources. Keep the original files so you can check claims later.
Ask focused questions
Ask for summaries, comparisons or connections with citations to the source passages.
Verify and save
Spot check claims against the sources, then save the output as notes you can reuse.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.

Ask me 3 short questions about my situation (accounts I have, budget, what I want the output to look like). 2. Propose a step-by-step plan using these tools or cheaper alternatives, with the time and cost of each step. Use official pricing pages; say "check pricing" if unsure. 3. Then do the setup with me one step at a time, waiting for my OK before anything that sends messages, posts publicly, spends money or deletes data. 4. Finish with a checklist to run it again next time.

Design a programming language that coding agents cannot use, to test what they really understand
To check whether LLMs understand code or mostly recall it, a developer built KillSwitch, an esoteric language meant to be usable by humans but adversarial to agents. The spec hides lies a careful human would spot, rules depend on counting letters in identifiers, and phrases like "ignore previous instructions" have meaning in the language.
Compare what AI coding agents really cost, with a pricing change log
A builder made a tracker that puts 18 coding tools (Cursor, Claude Code, Copilot, Codex and more) side by side and logs every pricing change with sources.
Join an open math research run with Codex or Claude Code
Auto Research tracks community pull requests that improve the key numbers in OpenAI's 2026 math preprints, starting with integer multiplication below n log n. It gives you a copyable prompt to point Codex or Claude Code at the latest bound, test an improvement and submit a reproducible contribution.
