Plus, we cover Meta’s latest LLaMA update, Anthropic’s safety benchmarks, and a glimpse at an intriguing new AI ethics debate circulating online.
Let’s get started.
📰 Trends & Headlines
💻 OpenAI Unveils Codex in ChatGPT
On May 16, 2025, OpenAI rolled out Codex, a specialized coding agent built on GPT-4-turbo. It can generate, debug, and refactor code across multiple languages right within your chat window—no additional extensions needed. Early users report productivity jumps of up to 30% in routine tasks.
📚 Meta Releases LLaMA 3 with 1 Trillion Parameters
Meta’s new LLaMA 3 model debuts this week, boasting 1T parameters and improved efficiency. It promises better on-device performance and tighter integration with Reality Labs products, pushing forward the frontier of large-scale open models.
🛡️ Anthropic Publishes Safety Benchmark “Shield”
Anthropic this week published “Shield,” a comprehensive set of adversarial tests designed to evaluate LLMs on harmful content, misinformation, and ethical boundaries. The benchmark is freely available for researchers aiming to build safer AI systems.
💬 Spotted on Twitter (and LinkedIn)
1. OpenAI Dev Advocate on Codex Early Feedback
An OpenAI developer advocate tweeted that early adopters are loving Codex’s “Explain This Code” command, which breaks down complex functions into plain English. Their takeaway: democratizing code understanding for non-developers could expand who builds software.
2. Sam Altman on the Next Phase of AI Tools
OpenAI CEO Sam Altman shared on LinkedIn that Codex represents “Phase 2” of AI tooling—moving from assistants that chat to ones that act. He hinted at upcoming features like multi-file project scaffolding and direct IDE integration.
3. AI Researcher’s Hot Take on LLaMA 3
A well-known AI researcher quipped on Twitter that scaling to 1T parameters is “impressive, but the real win is energy efficiency.” The comment sparked a thread on balancing compute scale with environmental impact—a conversation worth watching.

Last Day: Add 20,000 Subscribers to Your Email List!
MAY 05, 2025
Growing your email list is one of the most valuable investments you can make for your business.
An email list gives you direct access to an engaged audience, allowing you to build trust, nurture relationships, and drive conversions over time.
With Subletter, you'll gain subscribers who are already accustomed to reading newsletters, making them far more receptive to your content and offers.
These are highly qualified leads, much more valuable than those typically acquired through social media ads, where engagement is often fleeting and inconsistent.
By targeting readers who actively choose to subscribe, you’re building a loyal and relevant audience that can drive sustainable growth for your business.
Today is the final day to benefit from Subletter's powerful new feature.
It enables you to rapidly grow your email list with qualified leads by leveraging targeted recommendations.
Your newsletter will be showcased to hundreds of thousands of readers across hundreds of newsletters in your industry.
To make this recommendation feature even more effective, we’ve implemented a one-click opt-in system.
This means readers simply need to click a button in the newsletter they receive to subscribe to your email list.
You can then export your leads in CSV format from your dashboard and import them into your email platform (Substack or others).
To celebrate the launch of this new feature, we have a special offer for all beta testers.
This offer allows you to gain 20,000 subscribers on your email list for just $1,000 total.
That’s a fraction of the usual cost to build a list of 20,000 subscribers through traditional advertising channels.
Don't miss this opportunity to supercharge your growth!
The offer ends tonight at midnight.
