Claude 3 Model Series

The Claude 3 models, particularly Opus, excel in common AI evaluation benchmarks like MMLU, GPQA, and GSM8K, demonstrating near-human comprehension and fluency in complex tasks. These models also improve in analysis, forecasting, content creation, code generation, and multilingual communication.

The economic potential of Claude 3, particularly the Opus model, has been highlighted in its role as an economic analyst, suggesting its utility in specialized professional domains. When testing ourselves though and comparing against GPT-4 Turbo, we find little evidence to back this claim. With over 10,000 organizations already leveraging Amazon Bedrock for generative AI applications, the introduction of Claude 3 models is poised to further accelerate adoption.


Klu Claude 3 Hard Questions

Claude historically has issues with accuracy due to its ability to be very creative. This is most noticed when iterating on complex storylines. For Claude 3, accuracy has also been improved, with Opus showing a twofold increase in correct answers for complex, factual questions. The models will soon support citations for verifying answers.

Context length up to 1 million tokens

Klu Claude 3 Retrieval Recall

Initially, the Claude 3 models will have a 200K context window, with the potential for inputs over 1 million tokens for select customers. The models demonstrate robust recall capabilities, with Opus achieving near-perfect recall in the 'Needle In A Haystack' evaluation.


Claude 3 models deliver near-instantaneous results for live chats, auto-completions, and data extraction, with Haiku being the fastest and most cost-effective for its intelligence level. Sonnet offers double the speed of its predecessors with higher intelligence, while Opus matches their speed but with significantly enhanced intelligence.

The initial release of the Claude 3 models features a 200K context window, with plans to extend input capabilities up to 1 million tokens for certain customers. To remain competitive with Google Gemini 1.5's upcoming release, we expect to see Anthropic continue to push their generally available context window lengths.

Upcoming enhancements include the introduction of Tool Use (function calling), interactive coding (REPL), and advanced agentic capabilities.

Anthropic claims that the intelligence of the Claude 3 models is far from reaching its peak. Updates will be rolled out frequently in the coming months, focusing on expanding the models' functionalities, especially for enterprise applications and large-scale deployments.

Integration and support for Claude 3 models are streamlined for ease of use, with availability on major platforms like Amazon Bedrock and Google Cloud's Vertex AI. This ease of integration, coupled with significant backing from Amazon and Google, underscores the models' potential for widespread application across industries.


Each model has distinct features and costs, catering to different needs:

  • Opus is the most intelligent, ideal for complex tasks with a cost of $15 per million tokens for input and $75 for output.
  • Sonnet offers a balance of intelligence and speed, suitable for enterprise workloads at $3 per million tokens for input and $15 for output.
  • Haiku provides the fastest response for simple queries at $0.25 per million tokens for input and $1.25 for output.

Opus and Sonnet are currently available, with Haiku to follow. Sonnet powers the free experience on, with Opus for Claude Pro subscribers. Availability extends to Amazon Bedrock and Google Cloud’s Vertex AI Model Garden.

Anthropic plans frequent updates for the Claude 3 family, introducing features for enterprise use and large-scale deployments. The company aims to align AI development with positive societal outcomes and encourages feedback to enhance Claude's utility.
