Pairwise benchmark snapshot · Aug 17, 2026noindex (thin pair)
This page compares Claude Opus 4.5 (Anthropic) and Arcee AI: Trinity Large Thinking (arcee-ai) using the latest snapshots we have as of Aug 17, 2026. Arcee AI: Trinity Large Thinking wins on output price at $0.85/1M. Arcee AI: Trinity Large Thinking has the larger context window (262k tokens). Every cell below is a dated snapshot from a named public source — we do not invent missing scores, and we do not run SWE-bench ourselves.
Anthropic
Claude Opus 4.5Anthropic frontier coding and computer-use model. SWE-bench leader on the official mini-SWE-agent harness in the Feb 2026 refresh.
arcee-ai
Arcee AI: Trinity Large ThinkingAuto-discovered from OpenRouter (arcee-ai/trinity-large-thinking). Preview until a second source matches.
thinking_budgetReasoning models scale test-time compute by generating hidden chain-of-thought (CoT) tokens. These tokens are billed at standard output rates and directly expand latency (TTFT) in exchange for higher GPQA Diamond and SWE-bench Verified problem resolve rates.
