talking up the book - GPT 5

Companies building AI dev tools report positive results. Cursor calls it “the smartest coding model we’ve used.” Windsurf says it has “half the tool calling error rate” of other models. Vercel praises its frontend capabilities.

Beyond the tool companies, some founders and developers have shared their early experiences. GitHub’s CEO mentioned that GPT-5 shows promise for complex refactoring tasks. Several startup founders have noted improvements in code generation quality, though most emphasize they’re still in early testing phases.

It’s worth noting these companies have business incentives to promote AI adoption. The real validation will come from diverse development teams using it on actual projects rather than tool integrations.

Just loved this sign off.. been using mostly anthropic..
