How to Use Claude Fable 5 Anonymously

Anthropic's Fable 5 and Venice Anonymity [00:00]

• Anthropic has released its Fable 5 model, which is described as the world's most powerful for long-term autonomous tasks, deep reasoning, and multi-step projects.
• Venice is introduced as an AI provider that ensures user privacy by not storing prompts or conversation data.
• Venice offers access to various models, including open-source, Grok, image, and video models, some of which are end-to-end encrypted.
• Frontier models like Fable 5 are anonymized through Venice, meaning Anthropic is unaware of the user's identity unless disclosed.
• Fable 5 can be accessed via the Venice interface and API.

You can access Fable 5 through the Venice interface and through the Venice API, and in this video, we are going to explore demos in both.

Venice Account Creation and Model Selection [00:52]

• A Venice account can be created and API access/credits obtained without providing an email address.
• Users can sign in with a Web3 wallet as an alternative to using an email.
• Venice hosts hundreds of AI models, allowing users to select Fable 5.
• Models on Venice are ranked by privacy, with options for trusted execution environment (TEE) end-to-end encrypted usage.
• Users can view lists of anonymized models, private models (where conversations are not stored), and even uncensored or restricted models.

If we want to see the list of anonymized models, we can click over to that, and we have just simply the private models where the conversations are not stored.

Analyzing Large Documents with Fable 5 [01:43]

• Claude Fable 5 is highlighted for its ability to handle long-term projects and multi-step tasks requiring deep reasoning.
• An example demonstrates analyzing a large document, specifically a royalty-free book from Project Gutenberg (a 1.3MB plain text file).
• The analysis involved asking Fable 5 to summarize the text and identify its deeper meaning.
• This process utilized 33% of the context limit, indicating it handled over 300,000 tokens out of a 1 million token limit.
• The Venice interface allows file attachments and settings adjustments, including web scraping capabilities, system prompts, and temperature/top P for response creativity, though users are cautioned about potential hallucinations.

For an average user, Fable 5 is probably not necessary and it will be cheaper to use Opus 4.8 or even 4.7 to analyze long documents, to do deep reasoning, things like that.

Utilizing Fable 5 via the Venice API [03:37]

• The video shifts to demonstrating Fable 5's capabilities through the Venice API, noting over 250 models are available.
• An example uses the open-source coding agent at open-code.ai, switching the model to Claude Fable 5 on "high thinking" for enhanced processing.
• Requests made through this API setup are also anonymous, routed through Venice.
• A practical application involves scraping a website containing US bills passed in 2025 and 2026, saving each bill as an MD file.
• The scraped bills were then transformed into a basic, browsable web application with sorting and filtering capabilities.

And now Claude Fable will run through that. Uh so, here we see there is an API key to use. Let's actually use congress.gov instead, and we shouldn't be blocked.

Building an Application from Screenshots [05:39]

• Another project demonstrates building an app by providing screenshots of an existing application.
• Screenshots of the Venice platform's character creation screens were taken and placed in a new folder.
• The prompt instructed Fable 5 to imitate the app's functionality and interface based on the screenshots, using the Venice API.
• Fable 5 created a plan, which was approved, and then proceeded to build the application, asking clarifying questions.
• The resulting app, built by Fable 5, replicated the functionality of the Venice characters but with a new design and interface.

So, we'll just give it as many screenshots as we want. I've made a new folder and I've put these screenshots inside that folder.

Fable 5 as a Game Changer in App Building [06:52]

• Since Fable 5's release, building applications has been identified as a significant use case due to its long-term autonomous nature and improved task tracking.
• The built application was accessible via a local URL and required a Venice API key.
• The app allowed for character creation, summoning, and auto-generation of characters (e.g., "Ithilgard, an ancient star-weaving wizard").
• It also included features like creating images based on character descriptions and enabling voice models.
• The process of creating this app from screenshots and a single prompt is highlighted as a testament to Fable 5's capabilities, allowing for complete anonymity through Venice.

And you can see how this app is basically essentially just like the Venice characters just in a different format here.
