TLDR: OpenAI’s Codex is now in the ChatGPT mobile app, and developers are already using it to manage devices via Tailscale and continue sessions between phone and desktop. OpenCode 1.50.1 shipped pinned sessions with git worktree support, giving each PR its own isolated context. GPT-5.5 had a rough 48 hours in Codex due to two bugs OpenAI has since fixed, with usage limits reset. Anthropic committed $200M with the Gates Foundation to deploy Claude across global health and education.

<h2>Codex goes mobile</h2>
OpenAI shipped Codex inside the ChatGPT mobile app, and the reaction from developers has been immediate. People are starting sessions on desktop and picking them up mid-meeting on their phones, managing Tailscale device networks from an iPhone, and generally treating their laptops as secondary devices. OpenAI also teased a bidirectional ChatGPT-Codex integration with a cryptic “one day this will make sense” — something is coming there. A “Locked use” setting is reportedly in development that would let Codex operate on a Mac while the screen is locked.
<h2>GPT-5.5 degradation in Codex, now fixed</h2>
For roughly 48 hours, GPT-5.5 was noticeably weaker inside Codex. OpenAI identified two bugs, shipped fixes, and reset usage limits. No details on what the bugs actually were, but the team confirmed monitoring is ongoing. If you noticed Codex behaving strangely earlier this week, that’s why.
<h2>OpenCode 1.50.1: pinned sessions and worktrees</h2>
OpenCode shipped session pinning in 1.50.1, designed to pair with the experimental <code>/warp</code> feature. The workflow: each PR gets its own git worktree, you pin the session, and when you start your day you pick up exactly where you left off from a list. The worktree feature itself is coming out of experimental next week once one more complementary feature ships — the team is teasing what that feature is. There’s also an open architecture question about whether OpenCode should fork a background server on first launch so all clients (CLI, web, desktop) share one instance.
<h2>Anthropic commits $200M with Gates Foundation</h2>
Anthropic announced a four-year, $200M partnership with the Bill &amp; Melinda Gates Foundation to deploy Claude in global health, education, and agriculture. That’s four times the size of OpenAI’s $50M Gates Foundation deal. The work covers vaccine and drug research for neglected diseases, making epidemiological models accessible to non-specialists, and AI tutoring in sub-Saharan Africa and India. Benchmarks, datasets, and evaluation frameworks will be released as public goods.
