Here are the new features and updates in GPT-5.
🧠 Unified Multi-Model System with Real-Time Routing
GPT-5 merges multiple AI models into one integrated system:
- Fast & efficient core model for everyday tasks.
- Deep reasoning model for complex logic and multi-step planning.
- Real-time router that auto-selects the best model for your request.
When limits are reached, it seamlessly shifts to mini or nano models to keep your workflow uninterrupted.
📜 Massive Context & Memory Upgrade
Now supports 256,000 tokens — enough to process entire books, large codebases, or days-long conversations without forgetting earlier details.
✅ Sharper Reasoning & 45% Fewer Hallucinations
- 45% fewer factual errors than GPT-4o.
- 80% fewer than older o-series models.
- Reduces “sycophancy” — excessive agreement — leading to more objective answers.
💻 Exceptional Coding & Agentic Abilities
- New benchmark-leading performance on SWE-Bench Verified (74.9%) and Aider Polyglot (88%).
- Uses fewer tokens and tool calls, boosting efficiency.
- Handles agentic workflows: planning, executing, recapping multi-step projects with minimal human intervention.
⚡ Smarter Integrations & Personalization
- Gmail and Google Calendar connectivity.
- Custom chat personalities (Cynic, Robot, Listener, Nerd, and more).
- More natural, human-like voice options.
🎯 Accessibility & Flexible Pricing
-
Free tier includes GPT-5 access with daily usage limits.
-
Paid tiers (Plus, Pro, Enterprise/Edu) unlock higher limits and advanced “Thinking” versions.
🏢 Enterprise Adoption at Scale
-
Built into Microsoft 365 Copilot, GitHub Copilot, VS Code.
-
Available in Azure AI Foundry with compliance & safety controls.
-
Real-time routing ensures maximum performance in enterprise environments.
🛡️ Safety & Trust Enhancements
- Over 5,000 hours of safety testing.
- Improved handling of emotional distress scenarios.
- More transparent in admitting knowledge gaps.
