ClaudeGuide & Pricing
Core Identity Overview
Developed by Anthropic, Claude is a premier AI assistant globally recognized for generating the most natural, human-like, and logical text. Rather than outputting cold, machine-like responses, Claude writes with the dedicated care and depth of a senior chief of staff listening to your concerns. With the June 2026 release of the groundbreaking Claude Fable 5 (Mythos-Class) model, Claude has pushed the frontier of AI to an unprecedented level. Featuring a massive 1-million-token context window and 'Extended Thinking' reasoning mode, Claude can output up to 128,000 tokens of highly structured code and complex text. It has become the absolute benchmark for software engineering, long-horizon knowledge work, and deep scientific research.

Frequently Asked Questions (FAQ)
Q. What is the difference between Claude Fable 5 and Claude Mythos 5?
Both share the exact same underlying architecture. However, Claude Fable 5 is built with strict, conservative safety classifiers to prevent misuse in high-risk areas like cybersecurity or chemical synthesis. Claude Mythos 5 is the raw frontier model with those classifiers lifted, initially deployed only to trusted cyberdefenders under government collaborations (Project Glasswing).
Q. Why is Claude Fable 5 occasionally marked as 'Temporarily Unavailable'?
Due to Fable 5's extreme capabilities, the US Government issued an export control directive in June 2026 requiring Anthropic to temporarily suspend access for foreign nationals pending a review of safety filters. During this transient period, system calls seamlessly route back to the highly capable Claude Opus 4.8.
