Choose your fighter: Balancing competing requirements to select models for your AI SOC
Summary: Cisco Talos tested 66 model and reasoning combinations from Anthropic and OpenAI on a tool-assisted log-review task, using a synthetic 80,054-record corpus generated with EvidenceForge and four independently prompted reviewer personas across five rounds per condition. The top condition, GPT-5.6 Sol Ultra, scored a median 96.25 but took 33.72 minutes and cost $55.48 per panel, while GPT-5.6 Luna Low scored 58.25 at 3.24 minutes and $0.39.
What's compelling: Talos found that raising reasoning effort raised cost but not score - GPT-5.6 Luna's scores fell at every higher level, and Claude Opus 4.8 lost 9.5 points going from high to xhigh - so the model you assume is strongest may deliver worse analysis at greater expense. Format violations and safety refusals also blocked usable answers outright: Claude Sonnet 4.6 produced no complete panels at max, and Anthropic's Fable was excluded after safeguards blocked 21 of 31 attempts even under relaxed CVP guardrails.
