OpenAI Robotics is hiring, looking for exceptional full-stack hardware, ops, systems, and ML engineers to help us program and manufacture robots that are useful for society.

AI should be able to help people in the physical world. In the short term, we are focused on robots to support skilled workers to build our future infrastructure; in the long term, we imagine everyone having a personal robot doing anything they need.

Our world simulation research program, led by Aditya Ramesh (@model_mechanic), has evolved over the past year into OpenAI Robotics. Progress is rapid, and based on a foundation of co-design between robotics hardware and ML research.

If you love working hands-on across the robotics stack and want to build the future, please consider joining us. Send an email with your background and evidence of exceptional accomplishment to: robotics-recruiting@openai.com

• Run validators before or after work
• Scan prompts for secrets
• Log conversations to internal systems
• Create memories or customize behavior by repo or directory

⚙️ Programmatic access tokens provide scoped credentials for Business and Enterprise teams:
• Create tokens from ChatGPT workspace settings
• Use them in CI, release workflows, and internal automations
• Set expirations or revoke access when needed
• Keep usage tied back to the workspace

Codex made me money without me doing anything..

Huge turning point for me today, I asked Codex to go off and make me $5. It went out, found a small open-source security/audit bounty path, made a legit PR, followed up with the maintainer, kept my payment details private - (without me asking), handled the GitHub proof/verification loop, and got the work merged.

it spent about 22 hours working on multiple security audits.

Today I received my first payment from that experiment: $16.88.

That’s a $506.40/month run-rate if repeated daily.

Not life-changing money yet, but it's deeply exciting to live out Sam Altman's vision for AI, where it will just go out and make money for you. It's awesome to start to see the beginning of that.
