OpenAI has rolled out GPT-5-Codex, a fine-tuned version of GPT-5 built specifically for software engineering. It powers Codex across CLI, IDEs, GitHub, and ChatGPT — now becoming the default engine for coding tasks.

The Details:

  • Optimized for ā€œagentic codingā€ — autonomously debugging, refactoring, and building projects end-to-end

  • Adaptive reasoning lets it run fast for quick fixes and think longer for complex jobs (7+ hours tested)

  • Fully integrated with Codex CLI, IDE extensions, and cloud — enabling seamless local cloud workflows

  • Supports advanced code review: navigates dependencies, runs tests, and auto-fixes pull requests

  • Early users (Duolingo, Virgin Atlantic, Cisco Meraki, Ramp) say it outperforms existing review tools

Why it matters:

With GPT-5-Codex, OpenAI shifts Codex from an autocomplete helper to a true coding partner. This release raises the stakes in the AI coding race against GitHub Copilot and others, while tightening Codex’s role as an always-on engineering teammate.

šŸ‡ŗšŸ‡øšŸ‡¬šŸ‡§ U.S. Tech Giants Pour Billions Into U.K. AI

As Trump lands in London for a state visit, American tech firms are announcing massive investments into U.K. AI and cloud infrastructure — tying Britain’s digital future closer to U.S. companies.

The Details:

  • Microsoft: $30B by 2028, including $15B capex for the U.K.’s largest AI supercomputer with Nscale

  • Nvidia + OpenAI + Nscale: Launching Stargate U.K., a data center hub to power next-gen AI workloads

  • CoreWeave: $2B investment with Nvidia + DataVita to deploy advanced chips in Scotland

  • Trump + Starmer: Signing new AI & quantum pact alongside deals for low-cost AI energy

  • Big names in tow: Jensen Huang (Nvidia), Sam Altman (OpenAI), and Satya Nadella (Microsoft) join Trump’s visit

Why it matters:

The White House can frame these as Trump’s AI victories, while U.S. companies cement their foothold in Britain. For the U.K., it’s a chance to rebrand as an AI maker, not an AI taker — but it also deepens reliance on U.S. infrastructure.

Perplexity has secured $200M in fresh funding, boosting its valuation to $20B—just two months after raising $100M at $18B. With ARR nearing $200M, the AI search rival to Google continues its rapid rise amid antitrust tensions and bold moves like its $34.5B Chrome offer.

Dutch firm Nebius inked a $17.4B GPU deal with Microsoft—one of the biggest AI infra pacts ever. The five-year agreement, tied to its New Jersey data center, could hit $19.4B and fuels Nebius’ global AI cloud expansion.

Databricks just raised $1B, pushing its value past $100B. With $4B in revenue—$1B from AI alone—it’s now one of the world’s top AI/data startups. Backers include a16z and Insight, as demand for AI software keeps surging.

Claude, Anthropic’s Console, and APIs briefly went down Wednesday, sparking user panic. The glitch, blamed on a short backend issue, adds to recent reliability concerns as Anthropic scales its AI services.
