- Subject: Lovable / AI app builder
- Models affected: GPT-5.5, GPT-5.4

Lovable tested GPT-5.5 in early access and reports it outperforms GPT-5.4 on complex tasks, with a 12.5% improvement on the hardest benchmark at the same cost, 23.1% fewer tool calls per request, and 9.9% higher likelihood of resolving blocking tasks. The model is described as more cost-efficient and better at unblocking builders during stalled build sessions.

## Evidence

Verbatim from https://lovable.dev/blog/gpt-5-5-now-in-lovable:

> On our hardest benchmark GPT-5.5 is 12.5% ahead of GPT-5.4 at the same cost. It weighs consequences more carefully and produces output closer to what a senior engineer would accept on first review.
