Claude vs ChatGPT Comparison | Settling it Across 5 Criteria — Which Should You Choose?
For those wondering whether to choose Claude Opus 4.7 or ChatGPT, we have compiled the optimal choice by use case across 5 axes: coding, long-form text processing, images, agents, and pricing. This comparison references Anthropic's official information directly as of April 2026. As of June 2026, the latest flagship model has been updated to Claude Opus 4.8 (see the article summary for details).
If your work centers on coding, long-form text processing, or agent tasks, Claude Opus 4.8 is the top candidate. As the latest flagship as of June 2026, it offers a 1M token context window by default, and the ability to delegate your entire development workflow via Claude Code makes a decisive difference.
On the other hand, ChatGPT has an advantage for use cases that require image generation or GPTs integration. While Claude's vision feature is read-only, Claude's 2,576px support can actually come out ahead in scenarios that only require analyzing high-resolution charts and diagrams.
If you're unsure, the fastest approach is to compare both services' free plans against your actual workload. Since pricing plans and model specifications are updated frequently, we recommend checking the official sites for the latest specs before making your final decision.

FAQ — 4 Common Questions About Claude vs ChatGPT
Here are answers to the questions we receive most frequently from readers.
Q. Which is better at Japanese?
Both support conversation and document generation in Japanese. As neither Anthropic nor OpenAI's official benchmarks include direct numerical comparisons of Japanese language capability, we cannot make a definitive claim. We recommend trying both and choosing whichever suits your use case.
Q. Which is cheaper?
Claude Free is available from $0 at claude.com/pricing. For paid plans, Claude Pro is $20/month (or ~$17/month on an annual plan). ChatGPT Plus is approximately $20/month as a monthly payment (reference value; please confirm current pricing at the OpenAI official website).
Q. Which is safer?
Anthropic employs a safety approach called Constitutional AI and publishes its safety research Anthropic — Claude Official. An objective comparison of "which is safer" requires evaluation by a third-party organization, and we do not make a definitive claim in this regard, also in light of preventing misleading superiority claims.
Q. What is the difference between Claude and ChatGPT when using them via API?
With the Anthropic API, Claude Opus 4.7 input tokens are $5.00 / 1M tokens and output tokens are $25.00 / 1M tokens (50% off with batch processing). The 1M token context window and integration with Claude Code are its strengths for development use. For OpenAI's API pricing and specifications, please refer to the OpenAI platform documentation. In terms of ecosystem, OpenAI has a head start with its Assistants API and Function Calling, and offers rich third-party integrations.
