Claude and ChatGPT are no longer “similar chatbots.” In 2025, they represent two different philosophies:Claude —— deep thinking, analysis, and writing clarity；ChatGPT (GPT-5.1) —— creativity, multimodality, real-time interactivity
But here’s the catch: switching between two tools creates workflow friction.And the combined cost? Yes — it stacks up faster than you’d expect. Which is why having them in one place became a must-have for many users.
On GlobalGPT, you get both Claude 4.5 and GPT-5.1 side-by-side — no switching apps, no toggling subscriptions.

What’s the real difference between Claude and 聊天GPT in 2025?
Both models evolved significantly in 2025 — and the gap between them has shifted.Here’s the most accurate high-level breakdown:
Claude 4.5 vs GPT-5.1: Quick Comparison Table
| 特點 | Claude 4.5 | GPT-5.1 |
| Core Strength | Deep reasoning, long-form writing, coding accuracy | Multimodal generation, video/voice/image, versatility |
| Writing Style | Natural, human-like, stable | Structured, customizable, flexible |
| Coding | Best for large codebases & debugging | Best for prototyping & cross-modal UI |
| Multimodal | Image understanding only | Images, videos (Sora 2 Pro), voice |
| Context Window | 200,000–500,000 tokens | 128k (UI) to 1M (API) |
| 研究 | Excellent with long documents | Strong external search + summaries |
| 最適合 | Researchers, writers, developers | Creators, marketers, teams, students |
Claude represents deep intelligence—it thinks slowly, explains clearly, and handles complex logic without drifting off-topic. GPT-5.1 represents broad capability—it can process more types of data, work across more formats, and execute more diverse tasks in one session.
In practice, Claude feels like collaborating with a thoughtful senior analyst.
ChatGPT feels like collaborating with an entire creative studio.
Both are exceptional — but exceptional in different ways.
Claude vs 聊天GPT model lineup (2025 updated guide)
Since late 2024 and throughout 2025, both Anthropic and OpenAI have rebuilt their model families from the ground up.
To make the comparison meaningful, we must look at each ecosystem as a family of models—not a single version. That’s why we created the updated 2025 Claude vs ChatGPT model map below, reflecting all major releases, deprecations, and current flagship to
Model Lineup: Claude 4.5 Family vs GPT-5.1 Family
| Category | Claude Models | ChatGPT Models |
| Flagship | Claude Sonnet 4.5 | GPT-5.1 (default for Plus/Team) |
| Advanced Reasoning | Claude Opus 4.1 | o1 / o1-mini |
| Fast Lightweight | Claude Haiku 3.5 | GPT-5.1 Instant |
| Multimodal | Strong image analysis only | GPT-5.1 Image + Sora 2 Pro (video) |
| API Options | Stable + cheaper input tokens | More variants + cheaper output tokens |
The table shows how Claude 4.5 和 GPT-5.1 now represent two very different model ecosystems. Claude’s lineup focuses on reasoning depth 和 cost-efficient performance—with Sonnet 4.5 as the balanced flagship, Opus 4.1 for heavier reasoning tasks, and Haiku 3.5 for fast lightweight use. In contrast, GPT-5.1’s family emphasizes breadth and multimodality: the core GPT-5.1 model, o1-series for advanced reasoning, Instant for speed, and full support for image + Sora 2 Pro video generation.
簡而言之： Claude is optimized for thinking; GPT-5.1 is optimized for creating.
Which AI writes better in 2025 — Claude or 聊天GPT?
This is the category where users notice the difference immediately.
Claude 4.5 writes more like a human—warm, intuitive, emotionally aware, and consistently smooth across long documents. It feels like a writer who naturally understands tone and flow.
GPT-5.1 writes more like a high-precision system—structured, exact, highly controllable, and great at switching styles on command. It’s less “human,” but far better at clean structure, SEO-optimized output, and turning text into multiple formats.

Multimodal comparison — images, video, voice
When it comes to multimodality, the difference between Claude and ChatGPT isn’t subtle — it’s massive.
Claude 4.5 remains text-first with strong image analysis, but it cannot generate images or video. It’s great for reading charts, interpreting photos, or extracting data from documents, but that’s where multimodality ends.
GPT-5.1, on the other hand, is a full creative studio. It handles image generation, video creation, voice interaction, UI interpretation, screenshot-to-code workflows, and 實時 multimodal reasoning — all in one place. Combined with Sora 2 Pro video generation, it becomes the strongest multimodal model available to everyday users.
Multimodal Capabilities Table
| Capability | Claude 4.5 | GPT-5.1 |
| Image uploading & analysis | ✔ Excellent | ✔ Excellent |
| Image generation | ✘ Not supported | ✔ GPT-5.1 Image |
| Video generation | ✘ No | ✔ Sora 2 Pro |
| AI voice | ✔ Yes | ✔ Yes (more natural) |
| Real-time vision | Limited | ✔ Live Camera Vision |
| Document/PDF extraction | ✔ Best in class | ✔ Strong |
🏆 Winner:
GPT-5.1 (by a landslide)
If your work involves visuals, ads, UGC, product demos, animations, design concepts, educational videos, or creative workflows, GPT-5.1 dominates every category. Claude simply doesn’t compete in this space yet.
in short:
- Need visuals? → GPT-5.1
