9 direct benchmark disciplines evaluated across capability, speed, and cost
Original Claude 3 flagship. Kept so opus 3 vs later Opus and vs GPT-4o still resolve.
Open-weight-adjacent DeepSeek flagship. High reasoning density per dollar.
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.

Top DeepSeek vs top Anthropic Elo. Usually V4 Pro vs Opus 5. License and invoice decide as much as Elo.
2026-06 open-weight-adjacent flagship. The usual cheap-vs-Claude question starts here.
Jan 2025 reasoning model. Still searched. V4 Pro is the newer DeepSeek buy.
