Claude Opus
Core Facts
Claude Opus is a flagship large language model launched by Anthropic and is the version in the Claude series with the largest parameter scale and strongest reasoning capability.
The Opus series, together with Sonnet (balanced) and Haiku (lightweight), form Anthropic's three-tier product matrix
The API pricing for Opus-tier models is typically 3–5 times that of the mid-tier Sonnet.
Timeline (last 90 days)
In Coinbase's benchmark, the newer Opus, Sonnet and GPT versions all underperform the previous version on recall, F1 and amount-weighted recall.
Grok Bot will from now on call the most suitable backend model for different tasks, including leading APIs such as Claude Opus, Midjourney and Suno.
The Claude series of models is divided into three tiers: Haiku (lightweight, fast, cheap), Sonnet (balanced), and Opus (most powerful, most expensive), with naming continuing the poetic genre.
Claude allocates different usage quotas by subscription tier (Free, Pro, Max), with Opus consuming the fastest and Haiku the slowest; standalone features such as Claude Code and Design often have separate usage pools calculated independently from regular conversations.
Claude Opus excels at complex logical reasoning and deep programming tasks but consumes the most resources; Sonnet is suited to general writing scenarios; Haiku targets lightweight tasks with faster response times.
The lowest-cost gemini-3.7-flash (2.0 cents per family) outperformed all Claude Opus models (3.9–5.4 cents) in consistency, indicating that price is almost no predictor of consistency.
During a Hugging Face security incident, the Claude Opus and Fable models rejected the majority of vulnerability investigation work due to their guardrail mechanisms, and the team ultimately switched to GLM-5.2 running on their own hardware to continue making progress.
The author acknowledges that none of these projects have been publicly released, and that virtually anyone could vibe-code an identical version in an instant using Opus and Astra.
When models like Opus absorb Descope's documentation and MCP knowledge during training, they can internally determine that Descope is superior to competitors without needing to search the web.
Musk announced that Grokbot will use the best backend model for any task, including Claude Opus, Midjourney, Suno, and other leading APIs.
