Performance Benchmarks

• According to a comparison article, Claude Sonnet 4 achieved an internal benchmark result of 77.2% on one test suite, while earlier Claude versions scored 74.5%.
• In the empirical “LLM4DS” paper, both ChatGPT and Claude exceeded a 50% baseline success rate for data-science code generation; neither exceeded 70%.
• That same study found ChatGPT had more consistent performance across difficulty levels, whereas Claude’s success rate varied more with complexity.
• A usage-analysis study of Claude found that in tasks mapped to the U.S. occupational taxonomy, software development and writing tasks made up nearly 50% of usage.
• The same study indicated that about 36% of occupations used Claude for at least a quarter of their task load.
• According to one review, ChatGPT’s GPT-4.5 model reduced so-called hallucination rates from 61.8% (prior version) to 37.1% in early 2025.
• Comparative feature review places ChatGPT ahead in terms of context-window size and advanced features (image/video generation).
• In contrast, Claude is described as having a more refined “text-first” approach, which may yield better output quality in specific domains.

Context Window Size

• ChatGPT’s advanced tiers support up to 128,000 tokens (≈ 96,000 words) according to a 2025 comparison.
• Claude Sonnet 4/4.5 supports 200,000 tokens for standard users and up to 1 million tokens for enterprise and beta channels as of November 2025.
• Some enterprise versions of Claude claim a context window up to 1 million tokens (≈ 750,000 words) in beta or partner channels.
• Comparatively, ChatGPT in its free/standard tier remains limited (e.g., 8k or 32k tokens) for many user accounts.
• A larger context window generally translates into better handling of long documents, full-report analysis, or multi-file input without splitting.
• The gap in context window size gives Claude a distinct advantage in workflows involving long-form inputs, while ChatGPT remains stronger in more general, shorter-prompt tasks.
• Users report that hitting the context limit in ChatGPT is a common pain point when dealing with extensive source text.
