The AI model release everyone’s talking about. Anthropic’s new Mythos-class model, Claude Fable 5, has landed in Make
Claude Fable 5 with bigger context, sharper vision, and longer reasoning is live in Make. Plug it into your Make automations today.
If your scenarios need to read dense PDFs, inspect charts, or reason across a huge pile of text at once, you can now do that in one step instead of stitching together workarounds.
You’ve probably seen the name in the news: Fable 5 is Anthropic’s most talked-about release yet. It generated enough buzz (and, briefly, a U.S. government export review) to make headlines well outside the usual AI news cycle, before landing back home, generally available worldwide, on July 1. That’s not the kind of attention an incremental update gets.
Claude Fable 5 has landed in Make, giving you Anthropic’s new Mythos class model for complex document analysis, code tasks, and high-context reporting.
What’s new with Claude Fable 5 in Make
-
1M token context window by default: Feed full support logs, research notes, contracts, or product feedback into one prompt, then return one answer you can route to Slack, email, or your database. -
Advanced vision for messy real-world files: Read blueprints, financial charts, scanned PDFs, and multi-page technical docs, then turn them into structured fields your scenario can use. -
Stronger reasoning for code and knowledge work: Draft patches, summarize large datasets, compare documents, or generate structured outputs for downstream modules.
-
Built-in refusal handling for high-risk requests: Fable 5 can return stop_reason: “refusal” as a normal response, so you can branch your scenario and retry with Claude Opus 4.8 when needed.
How to use Claude Fable 5 in Make
Anthropic’s Claude Fable 5 is available in these Make native apps:
-
Make AI Agents for agentic workflow automations with your API key -
Anthropic Claude app for structured prompts with your API key
What you can automate with Claude Fable 5 in Make
-
Blueprint intake: Watch a Drive folder for new engineering PDFs, send them to Claude Fable 5, extract specs into JSON, and write the result into your ERP. -
Daily voice of customer report: Collect support chats, NPS comments, and sales notes all day, analyze the full set in one prompt, and post a clean summary to Slack every morning. -
GitHub issue triage: When a new bug lands, pass the issue, logs, and relevant files to Claude Fable 5, then draft a patch or pull request description for review.
Know before you build
Fable 5 is Anthropic’s most expensive model. Save it for scenarios that genuinely need frontier-level reasoning or its full 1M-token context window, and route lighter steps to Opus 4.8 or Sonnet 5 to keep automation costs down.
One more thing: Fable 5 carries a mandatory 30-day data retention period and isn’t available under zero data retention (ZDR). If your automations handle contracts, PII, or other data subject to a ZDR requirement, check Anthropic’s data retention docs before routing them through Claude Fable 5.

What will you build first with a model that can read the full file, see the chart, and return something your scenario can act on right away?
Happy automating!
