Pairwise benchmark snapshot · Aug 16, 2026noindex (thin pair)
Comparing verified benchmark accuracy, speed, and token pricing between Claude Opus 5 and GPT Image 2 (High). Review the complete breakdown below to determine which model best fits your performance and budget requirements.
Anthropic current default flagship. Official API $5/$25 per 1M tokens and a 1M context window (Anthropic, Jul 24 2026).
OpenAI flagship diffusion-transformer image synthesis model with supreme prompt adherence, realistic textures, and complex text composition.
Simulate accuracy gains vs added response time & token cost
Reasoning models “think before answering” by generating internal reasoning tokens. Higher effort improves math, coding, and logic accuracy, but increases response delay and token costs.
Single model data
No latency data
Unpriced
Category wins across reasoning intelligence, generation speed, and token cost.
Arena Preference Elo, prompt fidelity & typography score
Time to render full-resolution image snapshot (seconds)

| Target Workload | Recommended Pick | Evaluation Rationale |
|---|---|---|
| Repo / coding agents | insufficient data | Need SWE-bench on both sides. |
| High-volume chat | insufficient data | Need list prices. |
| Voice / low-latency UI | insufficient data | Need TTFT on both sides. |
| Long-document RAG | insufficient data | Need context sizes. |
| Screenshots / vision | insufficient data | Both accept images. Defaulting to the higher-Elo side (undefined). |
Usually Sonnet 5 vs Opus 5. Coding delta versus output $/1M. The workhorse question.
Top Anthropic vs top Google. Usually Opus 5 vs 3.6 Pro. Two different invoices.
Not a frozen 2025 article. Today that is usually Opus 5 vs GPT-5.6 Sol. Dated cells, not a brand fight.
Jul 24 2026 official API at $5/$25 and a 1M window. Preference Elo is taste, not a coding exam.
