Committed to answers at your fingertips

Fable Research now runs on the latest Fable 5.1 model. Felo Pro users can try it with half the usual credit cost for seven days from today.

Some questions need more than a quick answer. You may need to review multiple sources, compare competing viewpoints, and turn scattered findings into a clear, structured result. Felo Agent’s Fable Research has now been upgraded to the latest Fable 5.1 model, giving you a stronger starting point for deep research tasks.

To mark the upgrade, Felo Pro users can use Fable Research at half the usual credit cost for seven days from today. If you have a market question, competitor review, or research brief waiting on your list, this is a good time to try it.

What’s New in Fable Research?

The main change is the model upgrade: Fable Research now uses Fable 5.1. You can give the Agent a research question, relevant context, and a desired output, then use the result as a foundation for further analysis or content creation.

Fable Research is especially useful when you need to:

  • Organize information from several sources into a coherent overview.
  • Compare options such as products, strategies, markets, or research conclusions.
  • Explore a topic in depth before making a decision or starting a project.
  • Prepare a working brief for a meeting, presentation, article, or internal discussion.

The Agent page notes that the Claude Fable 5.1 model can consume credits quickly, so it is best to plan usage around tasks that genuinely benefit from deeper analysis. For a simple fact check or a quick lookup, Felo Search may be the more efficient choice. For a multi-step research question, Fable Research gives you a dedicated workflow to start from.

How to Use Fable Research

1. Open the Agent

Visit Fable Research and sign in to your Felo account. Felo Pro users can start testing the upgraded Agent right away.

2. Define the research goal

A focused prompt helps the Agent understand what a useful result should look like. Include:

  1. The question you want to answer.
  2. The purpose of the research.
  3. The scope, such as a market, time period, region, or audience.
  4. The preferred output, such as a table, report outline, or executive summary.

For example:

Compare three team collaboration tools in the Japanese market in 2026. Evaluate pricing, core features, best-fit teams, and potential limitations, then summarize the findings in a comparison table.

3. Review, refine, and follow up

Treat the first result as a research foundation. Check the key conclusions and coverage, then ask follow-up questions where you need more detail. You can ask Fable Research to investigate one point further, add a comparison dimension, or reshape the findings into a report outline, meeting brief, or content plan.

Half the Credits for Seven Days

From today, Felo Pro users get a 50% credit discount when using Fable Research for seven days. The offer gives you room to test a full research workflow or revisit a project where the usual credit cost made experimentation harder.

To get more value from the offer, prepare your research question and expected output before you begin. For a complex project, break the work into clear stages—for example, first map the topic, then compare the main options, and finally turn the findings into a decision brief. A focused process can make each research run easier to review and reuse.

The offer period is limited. If you have a market research task, competitor analysis, literature review, or content brief to prepare, open Fable Research now and experience the upgraded Fable 5.1 workflow.
