GPT-5 is here and Here’s the no-fluff breakdown 👇

1️⃣ One smart system, no model-picking!

You don’t have to choose between models now. GPT-5 has a built-in “smart router” that decides whether to give a quick reply or switch to heavy compute mode for complex stuff.

2️⃣ Big jump in reliability

OpenAI says GPT-5 cuts hallucinations by 45%–80% compared to older models. That’s a huge step toward using AI for serious, production-level work.

3️⃣ Better at important stuff

💻 Coding: Scores 74.9% on SWE-bench (state-of-the-art). This is now a strong engineering partner, not just a helper.

🔬 Reasoning & Science: Stronger in math (AIME), science (GPQA), and multimodal tasks.

✍ Writing: Handles structure, flow, and creativity much better, not just grammar fixes.

4️⃣ Access & pricing

- Live today in ChatGPT (replacing GPT-4o) and in the API.

- Comes in different sizes (-5, mini, nano).

- Handles 256k input and 128k output tokens.

- API pricing: $1.25/M input tokens, $10/M output tokens - competitive with Google Gemini 2.5.

💡 The big shift: GPT-5 isn’t here to impress you with fancy tricks - it’s here to get the job done. The “AI as a toy” era is over.
