Our Verdict
GPT-5.4 wins
GPT-5.4 wins on overall versatility and ecosystem depth, but Claude Opus 4.7 leads in creative writing quality and safety alignment. GPT-5.4's massive user base, plugin ecosystem, and competitive pricing give it the edge for most users.
The AI model landscape in mid-2026 is defined by a fierce rivalry between OpenAI and Anthropic. With GPT-5.4 (released March 2026) and Claude Opus 4.7 (released April 2026), both companies have shipped their most capable models yet. Both feature 1M+ token context windows, native reasoning capabilities, and agentic tool use. But they excel in different areas. This comparison covers 15 categories of real-world testing including coding benchmarks, creative writing, research analysis, cost efficiency, API reliability, and ecosystem integration. Whether you are a developer choosing your daily driver, a business evaluating enterprise deployment, or a curious power user, this guide provides the data you need to decide.
Every category compared head-to-head. Check marks indicate the winner in each category.
| Category | GPT-5.4 | Claude Opus 4.7 | Winner |
|---|---|---|---|
| Coding (SWE-bench Verified) | 74.9% | 74.2% | |
| Reasoning (GPQA Diamond) | 92.8% | 91.3% | |
| Writing Quality (Human eval) | Good (Canvas editor) | Excellent (128K output, natural prose) | |
| Context Window | 1M tokens | 1M tokens | |
| Max Output Length | 32K tokens | 128K tokens | |
| API Price (input / output per 1M tokens) | $2.50 / $15 | $15 / $75 | |
| Multimodal | Vision + audio + computer use | Vision + tool use | |
| Consumer Price | $20/mo (Plus) | $20/mo (Pro) | |
| Agentic Capabilities | GPT-5.4 Thinking, Computer Use | Claude Cowork, Claude Code | |
| Ecosystem / Plugins | GPT Store, 50K+ custom GPTs | Claude MCP protocol, growing integrations |
GPT-5.4 holds a slight edge on SWE-bench (74.9% vs 74.2%) and benefits from a larger developer ecosystem. However, Claude Opus 4.7 powers popular coding tools like Cursor and Windsurf, and its self-verification makes it excellent for debugging. For most developers, both are outstanding — choose based on your preferred IDE integration.
Claude Opus 4.7 is widely considered the superior creative writer. Its output is more natural, less formulaic, and it can produce up to 128K tokens in a single pass, enabling book chapters or long-form reports. GPT-5.4's Canvas editor provides a better editing workflow, but the raw output quality favors Claude.
At identical consumer pricing ($20/mo), GPT-5.4 offers better value for most users due to its ecosystem (GPT Store, plugins, DALL-E 3, Advanced Data Analysis). Claude Pro is better if your primary use is long-form writing or if you value safety alignment.
It depends on use case. For cost-sensitive deployments at scale, GPT-5.4's 6x cheaper API pricing is compelling. For high-stakes applications where safety and reliability are paramount, Claude Opus 4.7's superior alignment and self-verification justify the premium.
Both support vision. GPT-5.4 also supports audio input/output and computer use (gui agent). Claude Opus 4.7 focuses on vision and tool use. GPT-5.4 has broader native multimodal support, but Claude excels at interpreting complex visual data like charts and diagrams.
