Build an AI influencer and a full world with Fable 5 on Venice

Fable 5 and every model in one place

Fable 5 is a highly creative text model, and this guide uses it as the starting point for building a virtual influencer, a world bible, reference images, and a tuned content style. The whole project runs on Venice because it puts frontier models for text, image, and video in one platform.

On the text side you have models like Fable 5, Grok 4.3, and GLM 5.2. For images there are options such as GPT Image 2, Nano Banana 2, and Krea 2 Turbo, and for video there are models like Seedance 2.0 and Grok Imagine. Prompts are routed to these models either fully privately or anonymously, so you can use the strongest tools without exposing who you are.

The plan is to use Fable 5 for the heavy creative work, then switch to cheaper models once the world is built to save credits.

Prompt your influencer concept and art direction

Start by telling Fable 5 what you want. Describe who the influencer is, what content they make, and the exact look of their world. The more art direction you give, the more the model has to work with.

Here is the kind of detail to include in a single prompt:

Help me create a virtual influencer. She is a woman who shares insights into the
world of AI models and why privacy matters in our relationship with machine
intelligence. Her world is a serene cyberpunk version of Venice: sci-fi
Renaissance, Baroque facades laced with soft holographic filigree. Technology is
analog and cyber: brass, glass, and hand-worked detail over sleek screens. Marble
statues infused with technology. Ethos: dignity, not paranoia; self-sovereignty.
Deep blue and off-white colors, perpetual golden hour, warm stucco, no red at all.
Photorealistic, shallow depth of field, natural skin and material texture.

Lay out everything you can think of. You are giving the model a strong creative seed, not a finished spec, and Fable 5 will fill the gaps with its own high-creativity choices.

Request the world bible with large context chat

Before you ask for anything large, go to settings and toggle on large context chat. Fable 5 excels at long, complex tasks, and this option gives it the room to produce a full document without getting cut off.

Then ask for the complete world bible. Request settings and lore, visual canon, wardrobe, color palette, camera and render style, an official world seed for media generations, and a system prompt template. Tell it to ask you questions if it has any:

Now help me create an entire world bible: settings and lore, visual canon,
wardrobe, color palette, camera and render style. I need an official world seed
for media generations and a system prompt template. Ask me if you have any
questions. Let's begin.

Fable 5 returns the world (here, a city called La Serenissima), the character (Livia/Vittoria, a woman in her early 30s), the visual canon, a style seed for the world, a character seed, and a voice persona template.

Meet the world, refine it, and lock the canon

Fable 5 will come back with questions. This is the moment to go back and forth until the bible is tight, because you do not want to change these foundations later. A key question to settle: is your influencer a human or an AI? In this build she is an AI, and the content is vertical.

Answer every question, then ask for the finished bible in a format you can reuse:

Give me the full bible and any other artifacts in markdown format.

Markdown makes it easy to save and paste. Save the document to your computer for safekeeping and copy it, because it becomes the backbone of everything that follows.

Save the bible as a reusable system prompt

Turn your world bible into a system prompt so every future session already knows your brand. Open settings, go to system prompt, click add, and give it a name (for example, the influencer's name). Paste the entire bible into the field.

At the top of the pasted text, add a one-line instruction so the model knows its job:

You are the content creator assistant for Vittoria, the influencer in the
La Serenissima world. Always follow this brand bible.

Save it. You now have a toggle to switch this persona on or off. Leave it off for the reference-image step, since you want to stay in the world-building conversation, and turn it on later when you generate content.

Key takeaways

• Use Fable 5 with large context chat for the creative heavy lift: the world bible, character, seeds, and voice persona, then switch to cheaper models to save credits.
• Save the bible in markdown and load it as a system prompt so every session inherits your brand and character.
• Generate reference images across many models, one by one for fine control or in agentic chat to batch the whole set.
• Build video with 9:16 reference-to-video models, refine over a few rounds, and lock a production guide so output stays consistent, all while Venice keeps your prompts private and untrained-on.
