#OpenAIReleasesGPT-5.5 OpenAI Releases GPT-5.5: Next-Generation AI with Enhanced Reasoning and Real-Time Memory

San Francisco, April 24, 2026 – OpenAI has officially unveiled GPT-5.5, the highly anticipated upgrade to its large language model family. Building on the successes of GPT-4 and GPT-5, this new release introduces groundbreaking capabilities in long-context reasoning, real-time memory, and multimodal accuracy. The model is rolling out today to ChatGPT Plus, Team, and Enterprise users, with API access following next week.

Key Features of GPT-5.5

1. 2M Token Context Window

GPT-5.5 can process and reason over up to 2 million tokens in a single session – equivalent to reading all three volumes of The Three-Body Problem trilogy at once. This enables unprecedented analysis of entire codebases, legal documents, or academic libraries without losing coherence.

2. Persistent Memory Across Conversations

For the first time, the model features opt-in cross-session memory. It can remember user preferences, project details, and ongoing tasks from previous chats (within a user-controlled timeline). Users can view, edit, or delete any stored memory via the new Privacy Dashboard.

3. Real-Time Factuality Engine

GPT-5.5 includes a built-in live retrieval system that actively pulls current information from trusted sources (news, academic papers, public datasets) without requiring manual web search. A new citation panel displays every referenced source.

4. Advanced Multimodal Understanding

Image, audio, and video understanding has been refined – the model now describes complex visual scenes with 94% accuracy on internal benchmarks. It can also generate editable vector graphics and analyze medical imaging with disclaimer-based clinical guidance.

5. Tool Use & Code Execution 2.0

The updated code interpreter runs Python, R, and SQL in a sandboxed environment, with support for popular libraries like PyTorch and TensorFlow. GPT-5.5 can now debug live code, suggest optimizations, and even write unit tests autonomously.

Performance Benchmarks

· MMLU (multitask language understanding): 92.7% (up from 88.5% in GPT-4 Turbo)
· HumanEval (code generation): 84.3% pass@1
· DROP (reasoning over paragraphs): 89.1 F1 score
· Real-time knowledge cutoff: rolling (updated weekly)

Pricing & Availability

· ChatGPT Free: Limited daily queries (10 per day) with 128K context.
· ChatGPT Plus: $20/month – 2M context, priority access, memory features.
· ChatGPT Pro: $200/month – unlimited queries, advanced analytics, and early beta features.
· API: $0.02 per 1K input tokens, $0.06 per 1K output tokens (cached tokens at 50% discount).

Ethical Safeguards

OpenAI has implemented Constitutional Classifiers 2.0, reducing harmful outputs by 78% compared to GPT-4. The model refuses disinformation requests, impersonation, and malicious code generation with near-perfect accuracy. All outputs include invisible watermarks detectable by OpenAI’s verification tools.

How to Access

· Web & Mobile: Update your ChatGPT app. The model selector now includes “GPT-5.5 (Latest)”.
· API: Developers can request access via the OpenAI dashboard. Waitlist expected to clear within two weeks.
· Enterprise: Contact sales for on-premises deployment options.

What’s Next?

OpenAI CEO Sam Altman stated, “GPT-5.5 is the bridge to AGI capabilities. Our next focus is agentic workflows and long-term planning over months, not just minutes.” The company also announced a $10M grant program for researchers studying LLM safety using GPT-5.5.
