Long Context Performance

To further assess Claude 3.5 Sonnet's capabilities in handling long contexts, a "needle in a haystack" evaluation was conducted. This test involves inserting a small, crucial piece of information (the "needle") within a large amount of irrelevant text (the "haystack") and evaluating the model's ability to locate and utilize this information accurately.

The Claude 3.5 Sonnet model's long context accuracy varies across different context lengths and depths, with performance peaking at mid-range depths (36%-68%) for most lengths. Scores range from 1 to 10, with higher consistency and stability in performance observed at context lengths up to 126,500, while variability increases significantly at lengths beyond 151,000.

Availability

Claude 3.5 Sonnet is accessible for free on Claude.ai and the Claude iOS app, with higher rate limits for Claude Pro and Team plan subscribers. It is also available via the Anthropic API, Amazon Bedrock, and Google Cloud’s Vertex AI.

Accessible in 159 countries via claude.ai and its API, the Claude 3 models, including Opus and Sonnet, have already begun to impact the market, with plans to introduce Haiku soon. Anthropic claims models stand out in performing live customer chats, auto-completions, and data extraction tasks, demonstrating superior capabilities in benchmark tests when compared to competitors like OpenAI's GPT-4. Early tests leave some room for skepticism.

Frontier Intelligence at 2x the Speed

Claude 3.5 Sonnet pushes industry standards by setting new benchmarks in GPQA (graduate-level reasoning), MMLU (undergraduate-level knowledge), and HumanEval (coding proficiency). The model demonstrates significant advancements in comprehending nuance, humor, and complex instructions. It also produces high-quality content with a natural, relatable tone that resonates with readers.

Operating at twice the speed of its predecessor, Claude 3 Opus, Claude 3.5 Sonnet delivers a substantial performance boost. Its combination of cost-effectiveness and speed makes it the ideal choice for tackling complex tasks such as context-sensitive customer support and intricate workflow orchestration.

Our internal coding evaluation revealed Claude 3.5 Sonnet's impressive capabilities. The model successfully solved 64% of problems, significantly outperforming Claude 3 Opus, which solved 38%. This evaluation assesses a model's ability to enhance an open-source codebase based on natural language descriptions. Claude 3.5 Sonnet excels in independently writing, editing, and running code, making it an invaluable tool for updating legacy applications and migrating codebases.

In comparison to leading models from OpenAI and Google, Claude 3 Opus sets a new standard for conversational AI. It demonstrates superior performance in undergraduate and graduate knowledge, as well as grade school math. The Claude 3 Sonnet model further impresses with its ability to interpret scientific diagrams, highlighting its potential for enterprise operations and data analysis.

Claude 3.5 Sonnet is Anthropic's most advanced vision model, outperforming Claude 3 Opus in visual benchmarks. It excels in visual reasoning tasks like interpreting charts and graphs and can accurately transcribe text from imperfect images. This makes it ideal for industries such as retail, logistics, and financial services. Anthropic prioritizes AI safety, working to reduce bias and ensure neutrality, making Claude 3.5 Sonnet a top choice for both enterprise and consumer applications.

Claude 3 Model Series

The Claude 3 models, especially Opus, demonstrate exceptional performance in key AI evaluation benchmarks such as MMLU, GPQA, and GSM8K. These models exhibit near-human levels of comprehension and fluency when tackling complex tasks. They also show significant improvements in critical areas including analysis, forecasting, content creation, code generation, and multilingual communication.

Anthropic has touted the economic potential of Claude 3, particularly the Opus model, highlighting its capabilities as an economic analyst. This suggests its potential utility in specialized professional domains. However, our own testing and comparisons against GPT-4 Turbo have not yielded substantial evidence to support these claims. Despite this, the Claude 3 models are poised to accelerate the adoption of generative AI applications. Over 10,000 organizations already utilize Amazon Bedrock for such applications, and the introduction of Claude 3 models is expected to further drive this trend.
