You don't even want to know what sending 80,000 emails would cost you in 1 week. Postmark: $100+ SendGrid: $90+ Resend: $80+ Mailgun: $80+ OpenShip: $0. Deploy it on your 5$ VPS. Unlimited domains. Unlimited inboxes. No per-email bill. No vendor lock-in. And yes - it works with one-click setup. No deep infrastructure work. Just add a few DNS records, and you're ready to go.


Our co-CEO @ekindogus will be speaking at @RaiseSummit tomorrow. Join us at the Master Stage at 3:00 PM to hear more about the work we’re doing at Periodic.




1/ muse spark 1.1 is an industry-competitive agentic and coding model. across many agentic evals it rivals gpt-5.5 and opus-4.8. available now through the new meta model api and in meta ai. 🧵


Long-running models can solve hard open-ended problems, but their persistence can create safety risks that shorter-horizon evaluations miss. We’re sharing what we learned from studying a long-running model, and how those findings are shaping our approach to evaluations, alignment, monitoring, and user control. openai.com/index/safety-a…




hello there the jacobian conjecture is false thanx to my close friend akhil for asking about it and my other close friend fable for working during the world cup final ((1+xy)^3 z + y^2 (1+xy) (4+3xy), y + 3 x (1+xy)^2 z + 3 x y^2 (4+3xy), 2 x - 3 x^2 y - x^3 z): \C^3\to \C^3, has jacobian determinant -2, and sends (0, 0, -1/4), (1, -3/2, 13/2), and (-1, 3/2, 13/2) to (-1/4, 0, 0)


Congrats to Levent for discovering this! OOC I had an internal version of Codex attempt a proof too (without web search), and it discovered (essentially) the same counterexample! It wrote up a nice summary of the strategy here: aaronlou.com/jacobian_count…

Open-weight models in jeopardy from both the East and West. MofCom is China's Commerce Departmet equivalent.


Within OpenAI, we recently paused access for an internal model due to misalignment. See the blogpost for details. We have since improved our safeguards and redeployed the model. openai.com/index/safety-a…


Introducing ChatGPT Work, a new agent in ChatGPT powered by Codex and GPT-5.6. It can take action across your apps and files, stay with a project for hours if needed, and turn a goal into finished work. It’s a whole new way to get work done.
