1. A Smarter, Unified System
GPT‑5 introduces a unified architecture that blends speed, intelligence, and adaptability:
It uses a fast main model for routine queries, and a deeper thinking model for complex tasks.
A real‑time router automatically chooses the right model based on task complexity or if you explicitly ask it to “think hard.” Simon Willison’s Weblog+1Source+3OpenAI+3Simon Willison’s Weblog+3
This makes GPT‑5 both efficient and reliable in real-world usage.
2. Multiple Variants for Performance & Cost Needs
GPT‑5 is available in several versions:
Standard – full power and depth.
Mini – lower cost, still powerful.
Nano – fastest, ultra‑lightweight.
Each offers trade-offs between performance, latency, and expense. Cinco DíasWikipedia+7El País+7Cinco Días+7Simon Willison’s Weblog
3. Massive Context Window
GPT‑5 supports an expanded context window up to 256,000 tokens (some reports mention up to a million tokens). This allows the model to handle long documents, codebases, or conversations without losing track. WIRED
4. Better at Coding
GPT‑5 is OpenAI’s strongest coding model yet:
Excels at building front-end code, debugging large repositories, and even “vibe coding”—generating full apps from minimal prompts. Wikipedia+4OpenAI+4OpenAI+4
It achieves top scores on benchmarks like SWE‑Bench Verified, SWE‑Lancer, and Aider Polyglot.OpenAI+3WIRED+3Wikipedia+3
5. Expert-Level Writing & Reasoning
GPT‑5 delivers:
Writing with literary depth, rhythm, and nuanced understanding—even in tough formats like free verse or iambic pentameter. Source+7OpenAI+7OpenAI+7
Smarter reasoning across math, science, legal, and health contexts, acting like a proactive expert.OpenAI+2OpenAI+2
6. Multimodal & Agentic Capabilities
Supports text and image input, output remains text only. WIRED+6Simon Willison’s Weblog+6Cinco Días+6
Powers agentic tasks—performing multi-step actions via browser tools, APIs, and more (continuing capabilities like Operator and ChatGPT Agent). Reddit+10Wikipedia+10The Times of India+10
7. Safer, More Accurate, and Thoughtful
GPT‑5 is less prone to hallucinations, better at following instructions, and resists excessive flattery (reducing “sycophancy”). Financial Times+4OpenAI+4washingtonpost.com+4
OpenAI labels it “high risk” under safety frameworks due to its power; they’ve applied safe‑completion training and other safeguards. OpenAI
8. New API Features for Developers
Developers get:
A verbosity parameter to choose between short or detailed responses.
A reasoning_effort setting (minimal to high) for controlling depth vs speed.
Support for custom tools using plaintext interfaces instead of rigid JSON. OpenAI Community+1OpenAI
9. Wide Availability Across Platforms
ChatGPT users: GPT‑5 is live for free users (with caps), and Pro subscribers (~$200/month) get higher usage levels and access to “thinking‑pro” mode. Wikipedia+4washingtonpost.com+4The Times of India+4
Enterprise, Teams, Education: rolling out across all tiers soon. tomsguide.com+1
Microsoft Integration: GPT‑5 powers Copilot, GitHub Copilot, VS Code, Microsoft 365, and Azure AI services—with its smart router optimizing responses. Source+1
