+ GPT-5 Codex codes for 7hrs

Hey folks,
OpenAI may have just shifted the game for devs everywhere with GPT-5 Codex. This version tries to predict what youāll need next. Smarter code refactoring, sharper code reviews, and a kind of āautonomy modeā where it handles more of the repetitive stuff for you and can code independently for 7 hours. It adapts its reasoning time depending on how complex the task is which saves you time and tokens. Itās impressive on paper.
Letās dive in..

š Anthropic Report: AI Surge Is Real

š The Buzz: Anthropicās latest Economic Index shows Claude usage is growing fast. More employees using AI, more tasks being delegated, more countries coming online. But the flip side: adoption isnāt uniform. Richer places and tech-heavy firms are pulling ahead leaving a gap that could matter economically, socially, and for businesses everywhere. The data reveals:
Tasks shifting & trust rising: Coding still leads usage at ~36%, but educational tasks and scientific work also rose. Directive usage, telling Claude to just do something with minimal back-and-forth, jumped from 27% to 39%. That suggests people are getting more confident letting AI lead.
Geographic gaps are big: Claude usage per working-age population is way higher in high-income, well-connected countries. Singapore clocks in at ā¼4.6Ć expected usage, Canada around 2.9Ć. Meanwhile India, Nigeria, and Indonesia lag far behind their share of population in usage.
Within the U.S., local economies matter:
DC leads, closely followed by Utah, then California. Regions with strong tech, finance, or business support see more adoption, both for straightforward tasks and more advanced ones.Enterprises arenāt using AI just for fun:
When usage is via API (i.e. firms embedding Claude in their systems), automation dominates. About 77% of business API usage is task-delegation rather than human-AI collaboration. These are things like admin tasks, coding, document processing, areas where context is known and gains are clear.Cost isnāt the main blocker: Surprisingly, price doesnāt seem to be driving the decline in usage for higher-value tasks. Businesses appear more influenced by capability + how easily they can integrate AI into existing workflows. If context is messy or data siloed, even good models struggle.
š” Takeaway: Claudeās growth is impressive. Education, science, automation are all climbing fast. But the upside wonāt reach everywhere unless access, infrastructure, and organizational readiness catch up. The map of who benefits from AI might look a lot like the map of who already has strong tech ecosystems.

š VaultGemma: Googleās New Private LLM

š The Buzz: Google just dropped VaultGemma, a 1-billion-parameter language model trained from scratch using differential privacy. It's the most capable open model yet with privacy baked in that literally cannot remember your personal data, no matter how hard it tries.
Privacy built-in: VaultGemma uses differential privacy (DP) to protect the information it's trained on. It adds noise during training so the model doesnāt memorize specific data sequences. That means itās harder to extract private info from the model.
Scaling laws + trade-offs: Google Researchers and DeepMind worked out new āscaling lawsā for DP-trained models. Turns out you need bigger batches, more compute, or more data to get comparable utility. Smaller models just donāt perform as well if you demand strong privacy.
Performance close to old school models: VaultGemmaās benchmarks (tasks like reading comprehension, reasoning, etc.) are close to where non-private models were five years ago. It still lags modern models slightly, but the gap is shrinking.
Open access: The weights (the model itself) are released on Hugging Face and Kaggle, along with a technical report. Google wants the research community to build on it, improve it, and push the boundaries of private AI.
Privacy is no longer just one feature among many, itās essential. VaultGemma shows that you can train models with strong privacy guarantees without destroying usefulness. For sectors like health, finance, or anything with sensitive user data, this is a huge deal. It might shift expectations toward āprivacy-firstā AI, rather than āprivacy-after.ā
š” Takeaway: VaultGemma isnāt perfect, but itās a major proof that powerful, private AI is possible. As AI pushes deeper into sensitive areas, models like this will help shape whatās acceptable and could redefine how trust is built in AI.
