WHAT GPT-5 ACTUALLY CHANGED
GPT-5 launched in 2025. Here's what actually changed — and what didn't.
WHAT CHANGED
Model capability at the ceiling
Reasoning on complex tasks improved. Creative range expanded. Tool use became more reliable. The ceiling rose.
WHAT DIDN'T CHANGE
The floor for unstructured prompts
Bad prompts still get bad outputs. The model is more capable — but that capability requires specification to activate. The gap between ceiling and floor got bigger.
A more capable model with a bad prompt is still a bad output. Structure is still the unlock.
THE AI EDUCATION MARKET IS EXPLODING

WHAT YOU ACTUALLY PAY — TOTAL
Here's the full cost comparison — including what other tools don't tell you.
PROMPT-ENHANCEMENT SUBSCRIPTION
€25–50/mo for output, not skill
Monthly cost for a tool that improves prompts for you. Skill development: zero. Cancel: back to your original capability.
PROMPTCORRECTLY + BYOK
From €9/mo + €3–5 API for skill + output
Platform cost plus your own API access at cost price. Skill develops permanently. Cancel: keep the skill.
You pay for capability you keep, or for a service you rent.
