Anthropic <a href="https://www.anthropic.com/news/claude-fable-5-mythos-5" rel="noopener noreferrer nofollow">launched</a> the model Tuesday, opening its first Mythos-class system to the general public after months of testing it behind closed doors. The company applied one price card to Fable 5 and its safeguard-free sibling, Claude Mythos 5, at $10 per million input tokens and $50 per million output. Each sits at double the rate of Claude Opus 4.8, the firm's previous flagship.
TechCrunch <a href="https://techcrunch.com/2026/06/09/anthropic-released-claude-fable-5-its-most-powerful-model-publicly-days-after-warning-ai-is-getting-too-dangerous/" rel="noopener noreferrer nofollow">noted</a> the figure also doubles the input price of rival OpenAI's GPT-5.5. Even so, Anthropic frames it as less than half the cost of its earlier Claude Mythos Preview.
Developers can <a href="https://platform.claude.com/docs/en/about-claude/models/overview" rel="noopener noreferrer nofollow">reach</a> the model on the Claude API as claude-fable-5. VentureBeat <a href="https://venturebeat.com/technology/anthropic-brings-mythos-to-the-masses-with-claude-fable-5-its-most-powerful-generally-available-model-ever" rel="noopener noreferrer nofollow">reported</a> that Fable 5 is fully available from day one on the API and on consumption-based Enterprise plans. Anthropic expects demand to run high and hard to forecast, which shaped the slower consumer rollout.
Fable 5 stays free on Pro, Max, Team, and seat-based Enterprise plans through June 22, at no extra cost to current subscribers. From June 23, continued use will <a href="https://support.claude.com/en/articles/12429409-manage-usage-credits-for-paid-claude-plans" rel="noopener noreferrer nofollow">require</a> usage credits, though the company aims to restore standard access once capacity grows.

At list price, Fable 5 stands as the most expensive flagship any major lab sells for general use. Google'sGemini 3.1 Pro<a href="https://intuitionlabs.ai/articles/ai-api-pricing-comparison-grok-gemini-openai-claude" rel="noopener noreferrer nofollow">charges</a> $2 per million input tokens, while xAI'sGrok 4.1 asks just $0.20. Anthropic argues the premium buys efficiency rather than raw cheapness.
A pricing analysis <a href="https://www.finout.io/blog/claude-fable-5-mythos-5-pricing-benchmarks" rel="noopener noreferrer nofollow">found</a> that Fable 5 cleared a frontier physics task in 36 hours, using a third of the reasoning tokens GPT-5.5 spent over four days. Stripe told the company the model compressed two months of engineering into a single day on a 50-million-line Ruby codebase.
<a href="https://yellow.com/research/claude-mythos-ai-crypto-trading-risk" rel="noopener noreferrer nofollow">Anthropic first opened the Mythos</a> tier in April through Project Glasswing, limiting Claude Mythos Preview to government cyber defenders. That predecessor cost more than twice the new rate and reached only a restricted set of partners. Tuesday's debut marks the public's first path into the class.
