Overview
GPT-5 Mini vs Claude Opus 5 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
OpenAI / GPT-5 Mini
proDescription
OpenAI's smaller, faster GPT-5 model is built for well-defined tasks at low cost. GPT-5 Mini handles coding, writing, and analysis with the same reasoning-effort control as its larger siblings, at a fraction of the price. It reads text and images across a 400,000-token context. Its knowledge is dated, and OpenAI now points to newer models, but it remains a capable, economical everyday option.
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 Mini
proCost-Efficient Coding
Built for coding help at scale rather than the hardest engineering problems. Handles routine generation, review, and explanation reliably, and its low price makes it suited to high-frequency use inside applications.
Adjustable Reasoning Effort
Reasoning effort runs from minimal through low, medium, and high, so you trade thinking time against cost per request. Reasoning tokens are supported, so the model can work through a problem first.
Room For Long Documents
A 400,000-token context window, roughly 300,000 words. Enough for long reports, large contracts, and substantial codebases in one session, though short of the million-token frontier models.
Everyday Writing
Handles emails, summaries, documentation, and general content reliably. Aimed at clear, correct output on ordinary writing tasks rather than the polished long-form work of the flagship models.
Analysis On Dated Knowledge
Its knowledge belongs to the GPT-5 generation, with a September 2024 cutoff. That is dated, so time-sensitive work needs live sources rather than the model's own training.
Text And Image Input
Reads text and images in the same prompt, so you can send screenshots, charts, or scanned pages alongside your question. Output is text only.
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.
