ClaudeAnthropicClaude Opus 5 5

Built for long-running agentic coding and knowledge work, especially cross-file refactors, codebase audits, and complex multi-step tasks. Its 1M-token context, always-on adaptive thinking, and text/image input favor high-quality long-horizon execution; compared with Sonnet 5, it prioritizes depth at higher cost and latency.

$1.36/1M tokensClaudeAnthropicClaude Haiku 4 5

The fastest and more cost-efficient model in the Claude lineup, offering near-frontier capability with a 200K-token context window and thinking support. It fits real-time interaction, batch processing, lightweight agents, and cost-sensitive production; use Sonnet or Opus for the hardest reasoning or code changes.

$0.34/1M tokensClaudeAnthropicClaude Opus 4 8

Anthropic current Opus flagship for the most demanding reasoning, long-running agents, and high-autonomy coding. It supports a 1M-token context window and adaptive thinking; choose it when quality and reliability matter more than latency or cost.

$1.7/1M tokensClaudeAnthropicClaude 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.
