Claude Opus 4 5

An earlier Opus model in the Claude 4 family, focused on difficult coding, agents, computer use, deep research, and work with slides and spreadsheets. It fits workflows that require Opus-level capability with 4.5 compatibility; without that constraint, evaluate the newer Opus 4.6 or 4.7 first.

ClaudeAnthropicClaude Fable 5

Anthropic's most capable widely released model, built for the most demanding reasoning and long-horizon agentic work. Offers a 1M-token context window with 128k max output and always-on adaptive thinking, excelling at autonomously exploring underspecified tasks, planning, and carrying long-running coding and multi-agent orchestration further before it needs human input.

$3.4/1M tokensClaudeAnthropicClaude Sonnet 5

A daily-driver Sonnet-tier model aimed at bringing near-frontier agentic, coding, and knowledge-work capability at a lower operating cost. Its default 1M-token context and adaptive thinking fit long documents, codebases, and multi-step tool workflows; for the deepest reasoning or restricted high-risk security work, evaluate higher-tier or specialized models.

$0.68/1M tokensClaudeAnthropicClaude Opus 5

A premium model for complex agentic coding and enterprise knowledge work, emphasizing long-horizon planning, sustained execution, self-checking, and reliable delivery. With a million-token context window, it is suited to large codebases, complex documents, and multi-step projects that need limited human oversight.

$1.7/1M tokensClaudeAnthropicClaude Sonnet 5 5

A strong workhorse balancing speed and intelligence: a 1M-token context window, text and image input, text output, adaptive thinking, and tool use for project-level coding, multi-step tasks, and knowledge work. Its main advantage over Sonnet 5 is faster, more token-efficient execution; choose Opus 5.5 when maximum quality for harder tasks matters more.
