Felo Research now supports Claude Fable — Anthropic's most advanced model for deep research. Try it free for 7 days with Felo Pro.

We're excited to announce that Felo Research now supports Claude Fable — Anthropic's most advanced model for deep, multi-step research tasks. This integration marks a significant leap in what AI-powered research can achieve.

If you've been following the AI space, you've probably heard about Claude Fable. It's the model Anthropic built specifically for the kind of sustained, source-heavy reasoning that serious research demands. And now, it's available inside Felo Research.

Here's what this means for you, why it matters, and how to start using it.


What Is Claude Fable?

Claude Fable is Anthropic's latest model release, purpose-built for extended research workflows. Unlike general-purpose chat models that optimize for speed and brevity, Fable is designed to think longer, dig deeper, and produce more rigorous outputs.

The key capabilities:

  • Sustained reasoning over long contexts — Fable can track dozens of sources, cross-reference claims, and maintain coherence across research that spans thousands of words.
  • Stronger source attribution — it's trained to cite where information comes from, reducing the hallucination problem that plagues most AI research tools.
  • Multi-step decomposition — Fable breaks complex questions into sub-questions, investigates each one, then synthesizes findings into a unified answer.

The tradeoff? Fable consumes more compute per query than lighter models. That's exactly why we've integrated it as a dedicated option inside Felo Research — so you can choose when to deploy Fable's full power.

Why We Added Claude Fable to Felo Research

Felo Research has always been about giving users access to the best models for research tasks. We started with GPT-4o for speed, added Gemini for breadth, and now Claude Fable for depth.

Each model has its strengths:

  • GPT-4o: Fast, good for quick factual research
  • Gemini: Strong at cross-lingual and multimodal research
  • Claude Fable: Unmatched for sustained, source-heavy deep research

When Anthropic released Fable, we immediately saw it was purpose-built for exactly the kind of work our research agent demands. The model's ability to maintain coherence across long, multi-source investigations — while keeping citations accurate — was a clear step forward.

But a great model alone doesn't make a great research tool. You need:

  • A search infrastructure that can pull fresh, diverse sources in real time
  • An agent framework that decomposes questions and manages multi-step workflows
  • A multilingual platform that lets users research in their own language

That's the stack Felo provides on top of Fable. The model is the engine. Felo is the vehicle.


How Felo Research with Claude Fable Works

Felo Research is a deep research agent that channels Claude Fable's capabilities into a structured research pipeline:

  1. You submit a research question — anything from "How does CRISPR gene editing work in 2026?" to "Compare the regulatory frameworks for AI in the EU, US, and China."
  2. Felo Research decomposes the question into sub-topics and generates a search strategy.
  3. It searches, reads, and evaluates multiple sources in real time — weighing credibility, recency, and relevance.
  4. Claude Fable synthesizes the findings into a structured research brief with clear sections, source citations, and a summary you can actually act on.

Think of it as having a research analyst who never gets tired, never loses a tab, and never forgets to cite their sources.

Most AI search tools give you a summarized answer with a few links tacked on. That works for simple questions. It falls apart for complex ones.

Felo Research with Claude Fable is built for the questions that don't have a clean, one-paragraph answer:

Who Is Claude Fable Research For?

Researchers and analysts who need to quickly map a new domain. Instead of spending a day reading papers and compiling notes, you get a structured brief with citations in minutes.

Content creators and journalists who need factual depth. Felo Research surfaces the data, quotes, and source material you'd otherwise spend hours hunting for.

Product managers and strategists doing competitive analysis, market sizing, or technology evaluation. The multi-source comparison capability is where Claude Fable really pulls ahead.

Students and academics exploring a thesis topic or building a literature review. Felo Research helps you identify the key papers, debates, and gaps in a field — with proper citations.

Anyone making a decision that requires real evidence. Buying a house? Choosing a tech stack? Evaluating a career move? Claude Fable gives you the depth to decide with confidence.

Tips for Better Results

  • Be specific about scope. "What are the top 3 approaches to X?" gets better results than "Tell me about X."
  • Specify your audience. Adding "for a technical audience" or "for a board presentation" shapes the output.
  • Ask for comparisons. Claude Fable excels at structured comparisons — use that.
  • Iterate. The first brief gives you the landscape. Follow-ups let you drill into what matters.

Pricing and Availability

Felo Research with Claude Fable is available now for Felo Pro users with a 7-day free trial.

Since the Claude Fable model consumes credits quickly, we recommend planning your usage based on your actual research needs. The 7-day trial gives you enough credits to conduct several deep research investigations and experience the full capability.

After the trial, you can continue using Felo Research with other models (GPT-4o, Gemini) or upgrade to a Pro plan for continued Claude Fable access.


The Future of AI-Powered Research

The research workflow hasn't fundamentally changed in decades. You search. You read. You take notes. You synthesize. You repeat. AI has sped up individual steps — better search results, faster reading tools — but the overall process is still painfully manual.

Felo Research with Claude Fable represents a different approach: let the AI do the research, not just the searching.

With Claude Fable's reasoning capabilities and Felo's agent infrastructure, Felo Research doesn't just find sources — it reads them, evaluates them, cross-references them, and produces a coherent brief that would take a human analyst hours to compile.

This is the direction we're heading. From search to research to analysis, all in one conversation. And with Claude Fable on board, we're just getting started.
