Claude 5: What Anthropic Has Actually Shipped in 2026

The wait for “Claude 5” is effectively over, just not the way the rumor threads pictured it. Anthropic never shipped one monolithic model called Claude 5. Instead the fifth generation arrived tier by tier, and as of June 30, 2026 the newest piece is Claude Sonnet 5, the most agentic Sonnet the company has built, priced at an introductory $2 per million input tokens and $10 per million output. Above it sits a brand-new top class, the Mythos tier, whose public model Claude Fable 5 went live on June 9.

So the honest answer to “is Claude 5 out” is yes for Sonnet and for the Mythos class, and not yet for Opus, which is still on 4.8. This guide lays out exactly what has shipped, what each model is for, the one release everyone is still waiting on, and which Claude to actually use today. No leaked screenshots, no fake login pages, just the confirmed lineup and where it leaves you.

The Key Takeaways

• There is no single “Claude 5” model. Anthropic versions each tier on its own, so the 5-generation landed in pieces, not one launch.
• Claude Sonnet 5 shipped June 30, 2026 at $2/$10 introductory pricing (through Aug 31, then $3/$15), with a 1M-token context window and near-Opus quality.
• The Mythos tier is the real top of the range. Public model Fable 5 and its unrestricted sibling Mythos 5 launched June 9, sit above Opus, and returned July 1 after a brief government suspension.
• There is no Claude Opus 5 yet. The flagship you buy today is Opus 4.8 (May 28, 2026); an Opus 5 is the last major gap.
• You do not need to wait. Sonnet 5 for agents, Opus 4.8 for the hardest problems, and Haiku 4.5 for cheap volume already cover almost everything.

Is Claude 5 Out? Yes, Tier by Tier

Anthropic does not release a numbered “Claude 5” the way OpenAI ships a “GPT-5.” Each tier, Haiku, Sonnet, Opus, and the new Mythos class, carries its own version number and moves on its own schedule. That is why there was never going to be a single launch day. The 5-generation crossed over one tier at a time through the first half of 2026.

Two moments matter most. On June 9, 2026, Anthropic opened a fourth tier above Opus, the Mythos class, and made it publicly usable through Claude Fable 5. Three weeks later, on June 30, the Sonnet tier crossed into 5 with Claude Sonnet 5. Opus, meanwhile, stayed in the 4.x line, moving from 4.7 to Claude Opus 4.8 rather than jumping to a 5. You can read the full launch detail in TechCrunch and Anthropic’s Sonnet 5 announcement.

The Confirmed Claude Lineup (July 2026)

Here is every Claude model you can actually reach today, newest tier first. The Mythos class sits at the top, Opus remains the everyday flagship, Sonnet is the value-agent pick, and Haiku is the budget workhorse.

Model	Tier	Released	Price (in/out per M)	Best for
Fable 5 / Mythos 5	Mythos (top)	Jun 9, 2026	$10 / $50	Long autonomous work, security research
Opus 4.8	Opus	May 28, 2026	$5 / $25	The hardest reasoning and coding
Sonnet 5	Sonnet	Jun 30, 2026	$2 / $10*	Agents, everyday coding, long context
Haiku 4.5	Haiku	Oct 15, 2025	Lowest	High-volume, latency-sensitive tasks

*Sonnet 5 introductory pricing runs through August 31, 2026, then moves to $3/$15. Full numbers are in our Claude pricing breakdown.

What Each “5” Model Actually Is

Claude Sonnet 5

Claude Sonnet 5 is the headline of the group. Released June 30, 2026 with model ID claude-sonnet-5, it is built for agentic work: planning a sequence of steps, calling tools, reading the result, and continuing without a human nudging it at every turn. It ships with a 1M-token context window and a January 2026 knowledge cutoff, and it is now the default model for Free and Pro users on Claude.ai, plus Claude Code, the API, Cursor, VS Code, and GitHub Copilot.

The pitch is value. On agentic coding it scores around 63.2%, behind Opus 4.8’s 69.2% but well ahead of Sonnet 4.6, and on some knowledge-work tests it edges out Opus 4.8 outright, all at roughly a quarter of the price. For most people running agents or everyday coding, it is the new default.

Claude Fable 5 and Mythos 5 (the Mythos class)

Claude Fable 5 is the public face of Anthropic’s new top tier, a fourth step that sits above Haiku, Sonnet, and Opus. It launched June 9, 2026 at $10/$50 per million tokens, posted state-of-the-art results on most benchmarks it was tested on, and is built for long-running autonomous work rather than quick chat. Its unrestricted sibling, Claude Mythos, keeps the same capability with the safety layer removed and stays gated to vetted partners.

Both models were briefly pulled offline on June 12 under a US export-control order, then restored after the controls were lifted on June 30. Fable 5 came back globally on July 1, while Mythos 5 returned only to a set of approved US organizations. If you want the raw ceiling of what Claude can do, this is the tier, though the price and the gating make Opus or Sonnet the practical choice for most work.

Claude Opus 4.8 (still the flagship, not a 5)

Claude Opus 4.8 is the model that keeps the “Claude 5” question half-open. Released May 28, 2026 at $5/$25 per million tokens with a 1M-token window, it posts 88.6% on SWE-bench Verified and remains the strongest choice for the hardest reasoning and agentic coding. Anthropic chose to iterate the Opus line from 4.7 to 4.8 rather than crown an Opus 5, so the flagship tier is the one place the number 5 has not landed.

The One Still Missing: Claude Opus 5

If you are specifically waiting for a flagship “Claude 5,” the honest status is that it does not exist yet. There is no Claude Opus 5 in the API, the release notes, or the official models list, and Anthropic has not published a date. Prediction markets keep floating late-2026 windows, but those are guesses, not roadmap commitments.

That said, the Mythos tier arguably already delivers what an Opus 5 would have. Fable 5 and Mythos 5 sit a full step above Opus on capability, so in practice the frontier has already moved, just under a new tier name instead of a bumped Opus number. Treat any “Opus 5” leak, price sheet, or model ID as fiction until it shows up in Anthropic’s own docs.

Which Claude Should You Use Right Now?

You do not need to sit on your hands waiting for a bigger number. The current lineup covers almost every use case, and picking well saves both money and time. Use Claude Opus 4.8 when the task is genuinely hard, deep debugging, subtle judgment calls, or research where a wrong answer is expensive.

Reach for Claude Sonnet 5 for agent loops, everyday coding, and anything that feeds a large context, since it delivers close to Opus quality at a fraction of the cost. Drop to Haiku 4.5 for high-volume, simple jobs like classification, log analysis, or chat triage, where paying Opus rates would just be burning money. And if you would rather not juggle three model choices or separate subscriptions, Fello AI puts every Claude tier alongside GPT, Gemini, Grok, and DeepSeek in one app for Mac, iPhone, and iPad, so you can switch models mid-task and always land on the right one.

Conclusion

“Claude 5” turned out to be a generation, not a single model, and most of it is already here: Sonnet 5, Fable 5, and Mythos 5 are all live, with only an Opus 5 still outstanding. The practical move is to stop waiting and start using what shipped, Claude Sonnet 5 for value and agents, Claude Opus 4.8 for the hardest problems.
