What is Claude 3?

Claude 3 model is a large language model family developed by Anthropic and announced on March 4, 2024. The Claude 3 family has 3 members; Haiku, Sonnet, and Opus. The Haiku model is the smallest member of the family and is ideal for automating basic tasks. Although the Sonnet model is more advanced than the GPT-3.5 model, it is not as good as GPT-4. The Claude 3 Opus model is the most advanced model of the family and outperforms the GPT-4 model in most benchmarks.

How does Claude 3 work?

Claude 3 is an AI model that understands user inputs using algorithms such as Natural Language Processing (NLP), deep learning, machine learning, and neural networks and generates output using algorithms such as parameters, trained data, and safety rules.

In addition to textual input, the Claude 3 model can also analyse visual input and generate related output by understanding them. The Claude 3 model has the ability to analyse image inputs with high accuracy. Although it analysed images accurately one time in most of our tests, it rarely required a second prompt.

Claude 3 Features

The Claude 3 large language model has managed to surpass its predecessor, the Claude 2, in both performance and efficiency. Claude 3 models offer flexible use cases and advanced AI features such as large context window and prompt understanding. Let's take a closer look at the capabilities of Claude 3.

Context Window

Anthropic offered a context window of 100K tokens with the Claude 2 model. While this context window size was already sufficient to complete large-size tasks, they doubled it with the Claude 3 model. The Claude 3 model, with its context window of 200K tokens (approximately 150,000 words), is ideal for completing larger tasks and processing large amounts of data. Moreover, the Claude 3 Opus model offers a context size of 1 million tokens for specific use cases.

Prompt Understanding

The Claude 3 Opus model is more successful in understanding user prompts and generating accurate output than the GPT-4 model. Claude 3 Opus reads and understands the user's input and can generate the output the user needs. The Claude 3 Sonnet model, although not as successful as Opus, is successful in understanding the user's intent and generating related output. The Claude 3 Opus model has a score of 86.8% in the Massive Multitask Language Understanding (MMLU) test, while the Claude 3 Sonnet model has a score of 79.0%.

Top-tier Performance

The Claude 3 models, especially the Opus model, offer top-tier performance to users with their high scores in benchmarks. In particular, the Claude 3 Opus model managed to outperform both the GPT-4 and Gemini 1.0 Ultra models in tests such as MMLU for language understanding, GPQA for reasoning tasks, GSM8K for basic mathematics, and HumanEval for coding.
