Claude: Everything you need to know about Anthropic’s AI

Anthropic, one of the world’s largest AI suppliers, has a powerful family of generative AI models called Claude. These models can perform a series of tasks, from drawing images and writing e -mails to solving mathematics and coding challenges.

With the Anthropic ecosystem that grows so fast, it can be difficult to keep track of which Claude models do something. To help, we have put together a guide for Claude, which we will keep informed when new models and upgrades arrive.

Claude models

Claude models are named after literary artworks: Haiku, Sonnet and Opus. The latter are:

• Claude 3.5 HaikuA lightweight model.
• Claude 3.7 SonnetA midrange, hybrid reasoning model. This is currently the flagship AI model of Anthropic.
• Claude 3 OpusA big model.

Counter -intuitive is Claude 3 Opus – the largest and most expensive model anthropic offers – the least capable Claude model at the moment. However, that will certainly change when Anthropic releases an updated version of Opus.

Anthropic Claude has recently released 3.7 Sonnet, the most advanced model to date. This AI model differs from Claude 3.5 Haiku and Claude 3 Opus because it is a hybrid AI-reasoning model that can give both real-time answers and more, “thoughtful” answers to questions.

When using Claude 3.7 -Sonnet, users can choose whether they use the reasoning skills of the AI ​​model that encourage the model to ‘think’ for a short or long period.

When the reasoning is switched on, Claude 3.7 Sonnet will spend a few seconds to a few minutes in a “think” phase before he answers. During this phase, the AI ​​model breaks down the prompt from the user in smaller parts and check the answers.

Claude 3.7 Sonnet is the first AI model of Anthropic that is ‘reason’, a technique that many AI laboratories have used to traditional methods to improve AI performance.

Even with his reasoning for the disabled, Claude 3.7 Sonnet remains one of the best performing AI models of the technical industry.

In November Anthropic released an improved – and more expensive – version of his lightweight AI model, Claude 3.5 Haiku. This model performs better than the Claude 3 -OPUS from Anthropic on different benchmarks, but it cannot analyze images such as Claude 3 Opus or Claude 3.7 Sonnet can.

All Claude-Models-Die A standard context window 200,000 can also follow multistap instructions, Use tools (e.g. Stock Ticker trackers), and produce structured output in formats such as Json.

A context window is the amount of data that a model such as Claude can analyze before they generate new data, while tokens are subdivided bits with unprocessed data (such as the syllables ‘Fan’, ‘Tas’ and ‘Tic’ in the word ‘fantastic’))) . Two hundred thousand tokens is equal to around 150,000 words, or a novel of 600 pages.

Unlike many large generative AI models, Anthropic’s do not have access to the internet, which means that they are not particularly good at answering questions from current events. They also cannot generate images – only simple line diagrams.

Regarding the most important differences between Claude models, Claude 3.7 Sonnet is faster than Claude 3 Opus and he understands better nuanced and complex instructions. Haiku is struggling with refined instructions, but it is the fastest of the three models.

Claude -Modelprijs

The Claude models are available through Anthropic’s API and managed platforms such as Amazon Bedrock and Google Cloud’s Vertex AI.

Here is the anthropic API prices:

• Claude 3.5 Haiku costs 80 cents per million input tokens (~ 750,000 words), or $ 4 per million output tokens
• Claude 3.7 Sonnet costs $ 3 per million input tokens, or $ 15 per million output tokens
• Claude 3 Opus costs $ 15 per million input tokens, or $ 75 per million output tokens

Anthropic quickly offers caching and batching to deliver extra runtime savings.

With fast caching, developers can save specific “fast contexts” that can be reused about API calls to a model, while batching asynchronous groups of low priority (and then cheaper) model insertion requests.

Claude Plans and Apps

For individual users and companies that simply want to communicate with the Claude models via apps for internet, Android and iOS, anthropically offers a free Claude plan with interest limits and other restrictions.

Upgrading to one of the company’s subscriptions removes that limits and unlock new functionality. The current plans are:

Claude Pro, which costs $ 20 per month, comes with 5x higher tariff limits, priority access and previews of coming positions.

As a company-oriented, Team-that adds $ 30 per user per month per month cost-a dashboard to check invoicing and user management and integrations with data repos such as code bases and platforms for customer relationship management (eg Salesforce). A switch makes quotes possible to verify claims generated by AI. (Like all models, Claude hallucinates from time to time.)

Both Pro and Team subscribers get projects, a function that Output of Claude Onder in Knowledge Bases, which can be style guides, interview transcriptions, and so on. These customers, together with free users, can also use artifacts, a workspace where users can edit and add to content such as code, apps, website designs and other documents generated by Claude.

For customers who need even more, there is Claude Enterprise, with which companies can upload their own data to Claude, so that Claude can analyze the info and answer questions about this. Claude Enterprise is also supplied with a larger context window (500,000 tokens), Github integration for technical teams to synchronize their Github repositories with claude and projects and artifacts.

A word of warning

As is the case with all generative AI models, there are risks associated with the use of Claude.

The models occasionally Make mistakes when summarizing or Answer questions Because of their tendency to hallucinate. They are also trained on public web data, some of which may be protected or under a limiting license. Anthropic and many other AI suppliers claim that the Fair use Doctrin protects them against copyright claims. But that did not stop data owners by lawsuits.

Anthropic Provides a policy To protect certain customers against battles of courtroom that arise from challenges in the field of fair-use. However, they do not solve the ethical dilemma of the use of models that are trained on data without permission.
