Overview
GPT-5.5 vs Claude Opus 5 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
OpenAI / GPT-5.5
maxDescription
OpenAI's frontier model is built for complex professional work. GPT-5.5 takes on demanding coding, deep reasoning, and analysis across very large inputs. It reads text and images, searches the web for current information, and lets you dial its reasoning effort up or down depending on how hard the problem is. Priced at the premium end of OpenAI's range, and built to earn it.
Anthropic / Claude Opus 5
maxDescription
Anthropic's newest Opus model, and the successor to Opus 4.8. Opus 5 reaches near-frontier intelligence at the same price as the model it replaces, and lets you set how hard it works per task. It reasons before answering by default, checks its own output, and reads text and images across a very large context. Built for long-horizon coding and agentic work that runs with little supervision.

OpenAI / GPT-5.5
maxFrontier-Level Coding
OpenAI positions this as its model for the most complex professional work, with coding as the headline use. Handles large codebases, multi-step engineering tasks, and production-quality output.
Highest-Rated Reasoning
OpenAI's own model documentation rates its reasoning Highest, the top of the scale. Reasoning tokens are supported, so the model thinks before it answers, and you control how much thinking it does.
Large Context Window
1,050,000 tokens, among the largest available anywhere. Load an entire codebase, a full research corpus, or a large document set and ask questions across all of it. Prompts above 272,000 input tokens are billed at a higher rate.
Long-Form Professional Writing
Built for output that ships, not quick drafts. Writes up to 128,000 tokens in a single response, which covers long reports, full documentation sets, and extended technical writing without splitting the job up.
Live Web Research
Web search is a supported tool, so it can pull current information into an answer rather than working only from what it was trained on. Its knowledge cutoff is 1 December 2025, so anything more recent needs that search.
Text & Image Input
Reads text and images. OpenAI's documentation lists image as input-only and states that audio and video are not supported. File search is supported, so it can work across uploaded documents.
Anthropic / Claude Opus 5
maxSelf-Verifying Coding
Anthropic's strongest coding model. It produces code with minimal oversight, then checks its own work, catching and fixing its own mistakes before handing the result back rather than waiting to be corrected.
Effort You Set
A per-task effort dial from low to high. Low returns faster and cheaper on simple work; high lets the model reason as long as a hard problem needs. Thinking is on by default.
Consistent Full-Window Context
A very large context window with no smaller default. Anthropic states instruction following, tool calling, and reasoning stay consistent across the whole window, which matters for large codebases and long agent runs.
Enterprise Knowledge Work
Built for high-stakes enterprise and knowledge work. Suited to tasks where the output has to be right the first time rather than merely drafted, alongside its coding and agentic strengths.
Long-Horizon Agentic Work
Carries multi-step tasks through to completion with limited supervision, filling gaps in incomplete instructions, testing as it goes, and recovering from its own errors without a nudge.
Text And Image Input
Reads text and images in the same prompt, so you can send screenshots, diagrams, or scanned pages alongside your question. Output is text only. Audio and video are not accepted.
