After years of working on SDKs this is the one I'm most excited about. Check it out and let me know what you think!

We’re releasing GPT-5-Codex — a version of GPT-5 further optimized for agentic coding in Codex. Available in the Codex CLI, IDE Extension, web, mobile, and for code reviews in Github.

For Responses API: 1. Don't change instructions and tool in between turns 2. Only append items to the input, never change or remove 3. Set prompt_cache_key to a stable value across turns

There isn’t enough being said about efficient caching when deploying models in production. Structuring your input the right way can lead to 90%+ tokens being cached in agentic flows. Cached input tokens are 10x cheaper than non-cached ones.

Codex CLI now works with your ChatGPT login, with generous GPT-5 use included in the plus and pro plans. $ brew install codex $ codex It's that simple.

📣 We shipped major improvements to the Codex CLI today GPT-5, with usage included in your ChatGPT Plan (no API key needed) Upgraded prompt, harness, approvals & sandboxing logic... you name it Get the latest: 1. `npm install -g @openai/codex` -> v0.16+ 2. `codex login`

I’m looking for interview opportunities in Canada for my friend who fled Ukraine after the Russian invasion. She has a BS in CS and 2.5y experience in enterprise Java (Spring, SQL, Hibernate, JPA). Any help is much appreciated!

Today, speaking before the #US Congress, Zelenskyy showed this video.

They ask to cover the discounted shipping cost of 2.30 per lb.

Ukrainian shipping company is collecting humanitarian aid to be sent to Ukraine by plane on friday: https://t.co/22Z4jWN50t. List of required items is in post description. Please donate what you can.

To everyone who asked me what they can do to help:

A great recent interview with a C# and TypeScript architect Anders Hejlsberg:

Global using and file scoped namespaces are so nice. Removes a ton of boilerplate with very little downside.

Big thanks to @eehardt who figured out cross targeting for .NET built-in generators. Having a working example helped a lot.

I didn't think that cross-compiling the source-generator for multiple version Roslyn is something I need to worry about but it becomes a requirement if you want to run on .NET 5 but use new Roslyn features for .NET 6

It also supports both .NET 5 & 6 SDKs.

A new version of Jab compile-time Dependency Injection is out! Now with incremental compilation support and other fixes. https://t.co/Va7PV6fUVL
