Overview
GPT-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
maxDescription
OpenAI's earlier frontier model, still capable across coding, reasoning, and agentic work. GPT-5 costs substantially less than OpenAI's newest models and handles a large context window. The catch is age: its knowledge is dated, and OpenAI now labels it a previous-generation model. Worth picking when the task is general, the budget matters, and recency does not.
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
maxBudget Agentic Coding
OpenAI describes GPT-5 as its previous model for coding, reasoning, and agentic tasks across domains. It still writes, debugs, and reviews code across languages, and runs multi-step engineering work at a fraction of frontier pricing.
Adjustable Reasoning Effort
Reasoning effort runs from minimal through low, medium, and high, so you can trade thinking time against cost per request. Reasoning tokens are supported, so the model works through a problem before it answers.
Room For Long Documents
A large context window, roughly 300,000 words. Enough for long reports, large contracts, and substantial codebases in a single session, though short of the newer frontier models.
Long Outputs At Lower Cost
Produces long responses at a fraction of the price of OpenAI's newest models. Good value on long-form generation where the reasoning demand is modest rather than at the frontier.
Analysis On Older Knowledge
Its training data is dated by current standards, so it is fine for processing text you supply but weaker on recent events, which need live sources rather than the model's own knowledge.
Text And Image Input
Reads text and images in the same prompt, so you can send screenshots, diagrams, charts, or scanned pages alongside your question. Output is text only. OpenAI's documentation does not list audio or video input.
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.
