I’ll be honest—seeing this ranking, I was a bit surprised.
On April 17th, global AI model rankings updated: Claude Opus 4.7 claimed #1 with a total score of 92.3, surpassing GPT-6 (91.8).
Why surprising? GPT-6 was released just 3 days ago (April 14th)—shouldn’t it still be in its “honeymoon period”?
But after carefully reviewing the benchmark data, I get it.
First, Is This Evaluation Credible?
The evaluation organization is OpenBench, a relatively independent third-party platform. Their test suite includes:
- MMLU-Pro (knowledge understanding)
- HumanEval-X (code generation)
- GSM8K-Plus (mathematical reasoning)
- MT-Bench-Extended (multi-turn dialogue)
- Safety-Bench (safety)
Total: 5 dimensions, 20 points each, 100 points total.
The test suite design is reasonable—at least more credible than just looking at leaderboards.
Why Did Claude Win?
I compared Claude Opus 4.7 and GPT-6 scores in detail:
| Dimension | Claude Opus 4.7 | GPT-6 | Gap |
|---|---|---|---|
| Knowledge | 18.7 | 19.2 | -0.5 |
| Code | 19.1 | 18.9 | +0.2 |
| Math | 18.9 | 18.4 | +0.5 |
| Dialogue | 19.3 | 18.7 | +0.6 |
| Safety | 16.3 | 16.6 | -0.3 |
| Total | 92.3 | 91.8 | +0.5 |
See the pattern?
Claude leads across all “reasoning” tasks: math reasoning, multi-turn dialogue. GPT-6 excels at “knowledge” tasks: knowledge understanding, safety.
This aligns with both companies’ technical approaches.
OpenAI emphasizes GPT-6’s “AGI capability,” investing more in knowledge breadth and general abilities. Anthropic has focused on “reasoning depth” since Claude 3—Claude Mythos’ breakthrough is also centered on reasoning.
So if your use case is Q&A and content generation, GPT-6 might fit better. But for complex reasoning and multi-step tasks, Claude Opus 4.7 wins.
Where Did GPT-6 Fall Short?
Here’s what’s interesting. When GPT-6 launched, what did OpenAI highlight?
“40% performance boost,” “AGI’s final mile,” “10 trillion parameters”…
But looking at benchmark data, GPT-6’s improvements in code generation and math reasoning aren’t as dramatic as advertised.
Code generation: GPT-5.4 scored 18.7, GPT-6 scored 18.9—about 1% improvement. Math reasoning: GPT-5.4 was 18.2, GPT-6 is 18.4—about 1% improvement.
Multi-turn dialogue: GPT-5.4 was 18.5, GPT-6 is 18.7—again about 1%.
Bottom line: GPT-6’s performance gains concentrated in “knowledge understanding,” while reasoning improvements were minimal.
How should I put this… OpenAI’s marketing is somewhat “highlighting the good, hiding the bad.”
How Did Chinese Models Perform?
This evaluation also included Chinese models:
- DeepSeek V4: 89.7 total (global #4)
- Doubao 5.0: 88.2 total (global #7)
- Zhipu GLM-4: 87.5 total (global #9)
DeepSeek V4’s performance is impressive. While 2.6 points behind Claude Opus 4.7, it’s entered the “top tier.”
Specifically, DeepSeek V4 excels in code generation (18.8), close to Claude and GPT levels. But multi-turn dialogue and safety need work.
Overall, the gap between Chinese and international top-tier models is shrinking. From a “generation gap” two years ago to “catching up” now—progress is clear.
My Take
As someone who’s done NLP research, my attitude toward model rankings: reference, don’t worship.
Benchmarks only reflect performance on specific test sets, not real-world application capability.
For instance, test sets might not cover all scenarios: long-context understanding, multimodal capabilities, real-time inference… these matter in practice.
Also, user experience depends on API stability, response speed, pricing—factors rankings can’t capture.
So Claude Opus 4.7 taking #1 only means it performs best under current evaluation systems. For your specific use case, you need to test yourself.
One question: What should AI model evaluation standards be? General capability or domain-specific expertise?
My answer: It should be scenario-based. General models judged on general capabilities, specialized models on domain expertise. But here’s the problem: many models claim to be “general” while being clearly unbalanced in certain areas.
