|---|---|---|
| Vendor | Anthropic | OpenAI |
| Reference variant | Claude Sonnet 4.5 | GPT-4o |
| Context window | 200K tokens | 128K tokens |
| Input price | $3 $ / 1M tokens | $2.5 $ / 1M tokens |
| Output price | $15 $ / 1M tokens | $10 $ / 1M tokens |
| Knowledge cutoff | 2025-01 | 2024-10 |
| Best for | Complex reasoning, long-form writing, high-quality code, document analysis. | Versatility, multimodality (vision/audio), image generation, vast ecosystem. |
Strengths of Claude
- • Excellent grasp of nuance and long context
- • Structured, well-commented code with few hallucinations
- • Strong in academic and professional writing
- • Measured refusals (rare "as an AI…")
Strengths of GPT
- • Native multimodal (text, image, audio, voice)
- • Built-in image generation (DALL-E)
- • Vast plugin and integration ecosystem
- • Fast streaming response time
Limits of Claude
- • More expensive than peers on output tokens
- • No native image generation
- • No native web search (integrated by some wrappers)
Limits of GPT
- • Smaller context window than Claude/Gemini
- • Sometimes shallow on deep analysis
- • Filtering occasionally over-restrictive on neutral topics
Which one should you pick?
Pick Claude if…
Complex reasoning, long-form writing, high-quality code, document analysis.
Pick GPT if…
Versatility, multimodality (vision/audio), image generation, vast ecosystem.
Still undecided?
The best is to test both on a real question from your daily workflow. On Ask Aurel you can query Claude and GPT side by side (Compare mode) for a few cents, no subscription, and judge by results.
Frequently asked questions
Claude or GPT: which is cheaper?
GPT is overall cheaper ($2.5 per 1M input tokens, $10 per 1M output) than Claude ($3 input, $15 output). The real cost depends on your input/output ratio: heavy output use widens the gap in favor of the cheaper one.
Claude or GPT: which is better for code?
Claude is generally preferred for code by developers in 2026: structured output, few hallucinations, good comments. GPT remains a fair choice depending on context (budget, integrations).
Claude or GPT: which is GDPR-friendly?
Neither Claude nor GPT is European. Both provide GDPR-compliant Data Processing Agreements (DPA), but data transits through the US (or China for DeepSeek). For full sovereignty, Mistral AI remains the European reference.
What's the context window for Claude vs GPT?
Claude accepts 200K tokens of context, GPT 128K. Claude has the larger window, which matters for analyzing long documents (books, dossiers, codebases) in one request.
How can I test both AIs without subscribing?
