Claude 3.5 Sonnet vs. GPT-4o vs. GPT-4o mini — context window & modalities

Claude 3.5 Sonnet offers a generous maximum context window of 200k tokens, which is equivalent to approximately 150,000 words or 300 pages. Compared to that, the GPT-4o’s and GPT-4o mini’s context window of 128k tokens doesn’t seem so impressive anymore, but OpenAI compensates for it with a previously uncommon output limit of 16,384 tokens for both models — while Claude 3.5 Sonnet supports only 4,096 to 8,192 tokens (available in Anthropic API).

All three models are said to be multimodal, however, at the moment, this term has a different meaning for each of them:

  • Claude 3.5 Sonnet is capable of handling text and image inputs, 
  • GPT-4o extends these capabilities further by also supporting audio and video, 
  • GPT-4o mini can currently process only text in ChatGPT, text and image in API, and is promised to be fully multimodal (as in support also audio in video) in the future.

Claude 3.5 Sonnet vs. GPT-4o vs. GPT-4o mini — model size

When it comes to parameter counts, it looks like Anthropic is as “open” as its competitor, meaning: the numbers for Claude 3.5 Sonnet aren’t publicly known.

The internet speculates that GPT-4o has to be bigger than GPT-4, so it probably has more than 1.76 trillion parameters, but nobody seems to have any reasonable guesses on how many more. Similarly with Claude, there are no widely shared guesses about its size. All we know is that it was made to balance size and performance, so it’s highly possible it’s smaller than the flagship GPT. 

What about the GPT-4o mini? According to TechCrunch, it’s supposed to replace GPT-3.5 Turbo as the smallest model in OpenAI’s offer. Again, there’s no official information about its size, but it’s said to be in the same range as other small AI models (e.g. Llama 3 8b, Claude Haiku and Gemini 1.5 Flash), which suggests it may have around 8 billion parameters. 

Claude 3.5 Sonnet vs. GPT-4o vs. GPT-4o mini — accuracy & complex tasks

In terms of accuracy and performance on complex tasks, Claude 3.5 Sonnet and GPT-4o both stand out but in slightly different ways. Claude’s emphasis on advanced reasoning allows it to perform exceptionally well in scenarios that require nuanced understanding and detailed responses. According to its creators, the model is particularly effective in structured problem-solving and can handle intricate instructions with ease. 

GPT-4o is said to take these capabilities even a step further, thanks to its advanced architecture that enhances contextual understanding and maintains conversation flow over extended interactions, as well as audio and video processing abilities. This makes GPT-4o ideal for tasks involving ongoing dialogue or requiring a deep grasp of context. However, as we already know, both models achieve very similar results on various benchmarks.

GPT-4o mini, on the other hand, is designed for those who prioritize speed over complexity and seek more cost-effective options. While it’s less effective in handling complex tasks, it offers sufficient accuracy for everyday tasks (remember the benchmark table above?), making it a great choice for simpler applications where speed and lower costs are key priorities.
