SpaceX Bought Cursor: Your Bill, Your Code, Cost to Leave
SpaceX is buying Cursor for $60B. What changes for your bill, whether your code now trains xAI models, and the real cost per task of switching away.
Software that builds software
The model matters. The harness, workflow and economics around it often matter more.

SpaceX is buying Cursor for $60B. What changes for your bill, whether your code now trains xAI models, and the real cost per task of switching away.
Google ended free Gemini CLI access on June 18, 2026. The best alternatives (Claude Code, Aider, OpenCode, Antigravity) ranked by real cost per task.
Gemini 3.5 Flash lists at $1.50/$9.00 per million tokens: about 2x Haiku per token, yet roughly 3x cheaper per task than GPT-5.5 on agentic coding work.
A cost-first guide to building an AI agent harness: loop, context, tools, verification, and guardrails, and the token cost each layer controls.
Microsoft calls MAI-Code-1-Flash its cheapest coding model. In Copilot it bills like Claude Haiku 4.5 (0.33x); its token edge holds only on easy benchmarks.
Qwen 3.7 Max lists at half Claude Opus 4.8 and runs the same eval suite for a third of the cost. The catch is not hidden cost. It is what the price buys.
Codex leads Claude Code 83.4% to 78.9% on Terminal-Bench 2.1, but the prices match and the cheaper agent flips with your harness. The honest scorecard.
Composer 2.5 finishes a coding task for about $0.07, 10-60x under Claude Opus and GPT-5.5 at near-equal benchmark scores. What the cheap headline leaves out.
An independent replay of 500 Claude Code sessions found rtk, headroom, and caveman cut a $926 bill by just 3.7 percent. Here is why the 60-90% claims miss.
