Replit made OpenAI the default model for its coding agent after OpenAI reportedly offered more than 30% off a $100M+ a year contract. Claude is still available, but most users never change a default. It's the clearest sign yet of an AI price war.
OpenAI gave Cursor notice on August 28 with a proposed shutoff of November 12, using a change-of-control clause. Anthropic pledged more compute 36 minutes later. Anthropic also did the identical thing to Windsurf in June 2025 — and now rents 300 megawatts from the company that bought Cursor. The real story is supply-chain risk in the application layer.
Meta's Muse Code finishes third on its own benchmarks and first on price by 100x. Why the second number matters more — and what the discount costs.
xAI's new flagship is Opus-class for code at 1/8th the price: trained on real Cursor sessions, 500K context, native tool use. Where it fits.
A fake bug report hijacked coding agents at a Fortune 100 company. OWASP says prompt injection may be permanent. The security map just got redrawn.
Grok Build enters the coding agent race against Cursor, Claude Code, and Copilot. Why infrastructure matters more than any single model.
