GPT-5.5 Explained: Features, Pricing, and How OpenAI’s Autonomous Agent Compares to Claude 4.7

/

GPT-5.5

Key Takeaways

  • From Chatbot to Autonomous Agent: Released on April 24, 2026, GPT-5.5 is OpenAI’s latest flagship model, designed to plan and execute complex tasks independently.
  • Computer Use Capabilities: When paired with the OpenAI Codex app, GPT-5.5 can directly operate your computer—clicking, typing, and navigating software like a human.
  • Massive Token Efficiency & Context: It handles up to a 1 million token context window and uses significantly fewer output tokens to deliver high-quality results compared to GPT-5.4.
  • Pricing & Availability: GPT-5.5 requires a paid subscription (starting around $20/month) and is not available on the free tier.
  • The Best AI for the Job: While GPT-5.5 excels in coding and autonomous execution, Claude Opus 4.7 is better for nuanced writing, and Gemini 3.1 Pro remains the most cost-effective option.

What is GPT-5.5?

Released by OpenAI on April 24, 2026, GPT-5.5 is a fully retrained flagship AI model that marks a massive paradigm shift: the transition from a reactive chatbot to an autonomous AI agent. Instead of waiting for step-by-step prompts, you can simply assign a goal, and GPT-5.5 will autonomously create a plan, utilize necessary tools, and verify the final results to complete the task. This capability makes it a significant step toward Artificial General Intelligence (AGI).

GPT-5.5 vs. GPT-5.4: Key Upgrades

The biggest differences between GPT-5.5 and its predecessor, GPT-5.4, lie in unprecedented token efficiency and autonomous computer execution capabilities. Here is a breakdown of the major improvements:

Dramatic Increase in Token Efficiency

GPT-5.5 achieves the same or better quality of answers while consuming significantly fewer output tokens than GPT-5.4. By reducing unnecessary “overthinking,” the model arrives at correct answers more smartly. While the baseline processing speed is similar to GPT-5.4, this efficiency makes the perceived response time feel much faster.

“Computer Use” Integration via Codex

By integrating with OpenAI’s Codex application, GPT-5.5 can now physically interact with your computer screen. It can automatically click, type, and navigate browsers and desktop software. For instance, it can open a website, input data, launch screen recording software like OBS, and record a tutorial video entirely on its own.

Flawless Visuals with GPT Image 2.0

While GPT-5.5 is fundamentally a language model, its deep integration with the new GPT Image 2.0 generator has drastically improved image creation. The notorious issue of distorted text in AI-generated images has been virtually eliminated, making it capable of generating production-ready YouTube thumbnails and website mockups.

Rock-Solid 1 Million Token Context Window

GPT-5.5 supports a massive context window of up to 1 million tokens. You can upload lengthy PDF reports or massive source code files, and the model will maintain context without losing track of crucial details, allowing for highly accurate data analysis and code debugging.

How to Use GPT-5.5 on Desktop and Mobile

To access GPT-5.5, you must be a subscriber to a premium tier, such as ChatGPT Plus.

Using the Web and Mobile ChatGPT App:

  1. Log into your ChatGPT account and open a new chat.
  2. Open the model selection menu at the top left.
  3. Select “GPT-5.5 (Thinking)”.
  4. Adjust the “Thinking effort” to either “Standard” or “Extended” based on the complexity of your prompt.

Using the Codex App for Automation and Coding:

For local file access and autonomous PC operations, the dedicated OpenAI Codex app is the best approach.

  1. Install the Codex app on your PC.
  2. Set the model to “GPT-5.5” in the settings.
  3. Enter your prompt and toggle “Plan mode” to review the AI’s action plan before it executes.
  4. Enable “Computer Use” in settings to allow the AI to autonomously operate your PC for tasks like document creation or software testing.

Is GPT-5.5 Free? Pricing Explained

No, GPT-5.5 is currently not available on the free tier. Access requires a paid subscription starting around $20/month (equivalent to the typical ChatGPT Plus tier). For even more advanced reasoning, users can upgrade to the “GPT-5.5 Pro” tier, which costs approximately $110/month.

API Pricing for Developers:

For developers integrating GPT-5.5 into their systems, the API cost is double that of GPT-5.4.

  • Input tokens: $5.00 per 1 million tokens.
  • Output tokens: $30.00 per 1 million tokens. However, OpenAI introduced Context Caching. If the same prompt context is repeatedly used, the input cost drops drastically to just $0.50 per 1 million tokens, making iterative agent tasks highly cost-effective.

AI Model Comparison: GPT-5.5 vs. Claude Opus 4.7 vs. Gemini 3.1 Pro

The AI landscape is highly specialized today. The bottom line is: choose GPT-5.5 for coding and autonomous tasks, Anthropic’s Claude Opus 4.7 for elegant writing and design, and Google’s Gemini 3.1 Pro for deep Google ecosystem integration at a low cost.

While GPT-5.5 dominates benchmarks like Terminal Bench and OS World, Anthropic’s specialized “Claude Mythos” model remains highly competitive in niche fields like cybersecurity, largely due to its proprietary training data.
