My feed has already decided three things about Claude Opus 5:

"It launches in August."

"It will be Fable 5 without the restrictions."

"The benchmark leaks show another huge coding jump."

I spent an afternoon checking Anthropic's newsroom, live model catalog, pricing table, system-card index, and every Opus launch from 4.5 through 4.8.

None of those three claims is confirmed.

The useful story isn't that Opus 5 is definitely coming on a particular day. It's that Anthropic now has a conspicuous product gap between Sonnet 5 and Fable 5, and a new Opus could fill it.

TL;DR

• **No, Claude Opus 5 has not been announced.** There is no official launch page, API model ID, price, context limit, system card, or benchmark.
• Opus 4.5, 4.6, 4.7, and 4.8 arrived 73, 70, and 42 days apart. A cadence-only model points to July-August, but three intervals aren't a release calendar.
• Sonnet has already moved to generation 5. That makes the `Opus 5` name plausible, not confirmed.
• Fable 5 now costs $10/$50 per million input/output tokens. Opus 4.8 costs $5/$25. The cleanest role for Opus 5 is between Sonnet and Fable.
• I think $5/$25 is the strongest pricing hypothesis. I would not put it in a budget as fact.
• I wouldn't delay an Opus 4.8 deployment while waiting for a model that doesn't have an API contract.

What Anthropic actually lists today

The official [Claude model overview](https://platform.claude.com/docs/en/about-claude/models/overview) currently lists four main public tiers:

| Model | Official role | Input / 1M | Output / 1M |

| ---------------- | ---------------------------------------------- | ---------------: | ----------------: |

| Claude Fable 5 | Long-running agents, highest public capability | $10 | $50 |

| Claude Opus 4.8 | Complex agentic coding and enterprise work | $5 | $25 |

| Claude Sonnet 5 | Speed/intelligence balance at scale | $3 after Aug. 31 | $15 after Aug. 31 |

| Claude Haiku 4.5 | Fast, lower-cost work | $1 | $5 |

There is no Opus 5 row.

There is no `claude-opus-5` ID.

There is no Opus 5 system card in Anthropic's system-card index.

I keep repeating that because an API model name is one of the easiest rumors to fake. A string found in a client bundle can be a placeholder. A gateway catalog can use its own alias. A screenshot can be edited. I don't consider a model rea
