OpenAI's new GPT-5.3-Codex-Spark research preview runs on specialized hardware, hitting 1,000+ tokens/sec. What it means for Copilot's dominance.

GitHub has deprecated the entire GPT-5.1-Codex model family across all Copilot surfaces — Chat, inline edits, ask and agent modes, and code completions — effective April 1, 2026. The affected models include GPT-5.1-Codex, GPT-5.1-Codex-Max, and GPT-5.1-Codex-Mini. This is a significant rotation for developers who built workflows around those

OpenAI's Codex CLI has quietly carved out a niche as a terminal-first programming assistant — a lightweight alternative to full IDE integrations that lets developers stay in their command-line workflows while tapping into AI-powered code generation and task execution. Positioned against Claude Code, GitHub Copilot CLI, and a growing

The headlining addition is custom agents: teams can now define

GitHub has released the Copilot SDK in public preview, opening up the same production agent runtime that powers Copilot cloud agent and the Copilot CLI to any developer who wants to embed an AI coding agent into their own tools. The SDK ships across five languages — Node.js/TypeScript, Python,

OpenAI has quietly removed one of the biggest friction points for enterprise Codex adoption: the fixed seat fee. ChatGPT Business and Enterprise teams can now add Codex-only seats on a pure pay-as-you-go, token-based billing model — no upfront commitment, no rate limits, just usage tracked to the token. Alongside the change,

OpenAI made an eyebrow-raising move this week, acquiring TBPN — a daily business and technology talk show popular in Silicon Valley — for an undisclosed sum. Hosts John Coogan and Jordi Hays have built a loyal audience among OpenAI staff, AI researchers, and the broader tech executive crowd, offering live commentary on

The IDE wars just got a major new chapter. Cursor — the AI coding editor that became a darling of the developer community over the past two years — has announced Cursor 3, codenamed "Glass," a fully agentic interface designed from the ground up to let developers orchestrate multiple AI

On March 31, Anthropic accidentally shipped a 59.8 MB source map file inside version 2.1.88 of the @anthropic-ai/claude-code npm package, exposing over 512,000 lines of unobfuscated TypeScript across 1,906 files. The leaked source included Claude Code's complete permission model, every bash security
