If you're a code forge competing with GitHub and you look anything like GitHub then you've already lost. GitHub was the best solution for 2010. It is hanging on by a thread in 2026 (but its mostly down nowadays). The needs of today are so different that the form factor doesn't work anymore.

Opus is worth it, and maybe cheaper all-in than Sonnet? Early rough non-representative numbers, for our own internal @AmpCode usage (avg cost $ per thread): - Sonnet 4.5: $1.83 - Opus 4.5: $1.30 (earlier checkpoint last week was $1.55) - Gemini 3 Pro: $1.21








Good news! GPT-5 should now be significantly faster in Cursor. Big thank you to OpenAI for rolling out improvements to caching and API latency! P95 is ~2x faster versus before.
