Claude Mythos 5 is Anthropic’s restricted-access Mythos-class model — the same underlying model family as Fable 5 but with fewer safeguards and stricter access controls. It is limited to approved Project Glasswing and trusted-access partners. This guide covers what Mythos 5 is, how access works, benchmark data, safety design, and when Mythos-class capability matters versus Fable 5 or Opus 5.
A head-to-head comparison of Claude Opus 5 and Claude Sonnet 5: benchmark deltas, pricing tiers, feature differences, and a practical decision framework. Opus 5 leads on complex reasoning and agentic coding; Sonnet 5 delivers strong everyday performance at lower cost. Includes use-case breakdowns, competition context, and FAQ.
Every Claude model and pricing tier in one guide. API pricing for Fable 5 ($10/$50), Opus 5 ($5/$25), Sonnet 5 ($3/$15 intro $2/$10), and Haiku 4.5 ($1/$5) per MTok. Subscription plans from Free to Enterprise. Prompt caching, batch API, fast mode, and cross-provider comparisons — all verified July 25, 2026.
Claude Opus 5 launched July 24, 2026. It delivers near-Fable 5 intelligence at Opus pricing ($5/$25 per MTok), with a 1M-token context window, 128K max output, and state-of-the-art results on Frontier-Bench, ARC-AGI 3, and OSWorld 2.0. This guide covers benchmarks, pricing, safety, access, and how Opus 5 compares to Fable 5, Sonnet 5, and the competition.
Anthropic’s new Record a skill command lets paid Claude users demonstrate a task on screen, explain decisions aloud, and convert that demonstration into a reusable Cowork workflow.
A decision guide to Claude Pro: what the paid plan documents about session capacity and limits, how US pricing and local checkout totals work, how Projects affect the calculation, who should upgrade, and how to run an honest personal trial.
A beginner-friendly walkthrough of Claude Code covering setup, the orient-specify-plan-change-verify loop, a first-session example, use cases, prompting tips, safety guardrails, and troubleshooting.
A deep but careful answer to the Claude consciousness question: Anthropic’s J-space research, hidden internal thoughts, Jacobian lens, global workspace theory, safety auditing, and why this is not proof Claude feels anything.
A practical guide to Claude Sonnet 5: release date, API model name, introductory pricing, benchmarks, Claude Code availability, safety changes, and when to use it over Sonnet 4.6 or Opus 4.8.
