Claude Fable 5 in Claude Code: What to Use Now

Claude Fable 5 cannot be used in Claude Code right now because the model has been suspended, so it is not selectable in Claude Code or available through the API as of June 2026. Claude Opus 4.8 is the recommended Claude Code model today, and pairing it with the xhigh effort setting gives you the strongest available option for hard, long-horizon coding work.

This guide explains exactly what is happening with Fable 5, what to run in Claude Code instead, and how to set yourself up so the switch back to Fable 5 is effortless once it returns. The short version: you are not missing anything you can act on, because the most capable model anyone can run in Claude Code right now is Opus 4.8.

Can you use Fable 5 in Claude Code right now?

No, Fable 5 cannot be used in Claude Code right now because Anthropic globally suspended the model around June 12, 2026, within roughly 72 hours of its June 9 launch. The suspension was reported as a response to a U.S. export-control directive tied to a jailbreak concern, and it removed Fable 5 from both Claude Code's model picker and the public API.

The suspension also covers Mythos 5. It does not touch the rest of the lineup: Opus 4.8, Sonnet 4.6, and Haiku 4.5 are all unaffected and fully usable in Claude Code today.

Anthropic has described this as temporary rather than a permanent ban, but as of June 2026 there is no confirmed return date. So if your plan was to point Claude Code at Fable 5, the practical answer is to choose from the models that are actually available.

What to use instead

The best model you can run in Claude Code today is Claude Opus 4.8, the recommended high-capability coding model and the standard high-end choice for agentic work. Below is how the available options compare, with current per-million-token pricing.

For most serious work in June 2026, default to Opus 4.8. Reach for Sonnet 4.6 when you want faster turnaround on simpler edits or you are iterating rapidly and want to keep token costs down. Fable 5 stays in the table as a planning reference, not a current option.

Effort settings for coding

For the hardest coding and agentic tasks, xhigh effort on Opus 4.8 is the recommended setting. Higher effort lets the model spend more reasoning on planning, multi-file changes, and long-horizon runs where one wrong step compounds.

That extra thinking is not free in time or tokens, so it is best matched to genuinely difficult problems: large refactors, tricky debugging, or multi-step agentic tasks. For routine edits, a lower effort level or a switch to Sonnet 4.6 keeps you moving quickly without overpaying for reasoning you do not need.

What changes when Fable 5 returns

When Fable 5 comes back, it would become the top tier for the most demanding long-horizon coding in Claude Code. With a 1M-token context window, 128K output, and adaptive thinking always on, it is built for the kind of sprawling, multi-file agentic runs that push other models to their limits.

At $10 in / $50 out per million tokens, Fable 5 carries a premium over Opus 4.8, so it is not a default-for-everything model even when available. The sensible pattern is to keep Opus 4.8 as your everyday driver and escalate to Fable 5 only for the hardest runs where its extra capability earns the cost.

Until there is a confirmed return date, treat all of this as forward planning. Nothing about the suspension changes what you should run today.

A practical tip for picking a model

The simplest rule for picking a Claude Code model is to match the model to the difficulty of the task rather than always reaching for the most capable option. Start by asking how much reasoning a job actually needs before you choose.

Use Sonnet 4.6 for fast, well-scoped edits and quick iteration. Move to Opus 4.8 at xhigh effort when the task is hard, spans many files, or runs as a long agentic chain. Keep a mental note that Fable 5 is the eventual escalation tier for your most demanding work, so when it returns you already know where it fits.

Limitations and Tradeoffs

Fable 5 is unusable in Claude Code right now, so any guidance assuming you can select it is out of date as of June 2026. These recommendations may shift when the model returns and pricing or positioning is reconfirmed.

The constant across all of it is the same: keep your model choice matched to the task. The highest-priced model is not automatically the right one, and the cheapest is not always enough.

FAQ

Can I use Claude Fable 5 in Claude Code?

No. Fable 5 is suspended as of June 2026, so it does not appear as a selectable model in Claude Code and cannot be called through the API. Use Opus 4.8 instead.

What is the best Claude Code model right now?

Claude Opus 4.8 is the recommended high-capability model for Claude Code today, at $5 in / $25 out per million tokens. Run it at xhigh effort for the hardest work.

Is Opus 4.8 good for coding?

Yes. Opus 4.8 is Anthropic's recommended high-capability coding model and the standard high-end choice for Claude Code, especially at xhigh effort for complex, multi-file, and agentic tasks.

Will Fable 5 work in Claude Code when it returns?

That is the expectation. Anthropic has described the suspension as temporary, and when Fable 5 returns it would be the top choice for the most demanding agentic coding runs. There is no confirmed return date yet.

Should I use Sonnet 4.6 or Opus 4.8 in Claude Code?

Use Sonnet 4.6 ($3 / $15) for fast iteration and well-scoped edits, and Opus 4.8 ($5 / $25) for harder, long-horizon work. Match the model to how much reasoning the task needs.
