TL;DR: Reasoning LLMs such as o1, Claude 3.7 Sonnet, and DeepSeek R1 improve performance on math, coding, and multi-step tasks by generating long inference-time reasoning traces, but that comes with higher latency, higher cost, and sharper alignment and reliability concerns, according to WorkOS. The governance question is no longer whether these models can reason, but which identity controls still assume predictable, human-paced, low-compute behaviour.
Editorial analysis by NHI Mgmt Group, based on content published by WorkOS: “How well are reasoning LLMs performing? A look at o1, Claude 3.7, and DeepSeek R1”.
Key questions
Q: Why do reasoning LLMs create new identity governance risk?
A: They extend decision making into the inference phase, where the model can deliberate, choose tools, and act before producing an answer.
Q: Why do reasoning models make traditional IAM assumptions weaker?
A: Traditional IAM assumes the subject's access needs can be predicted before execution.
Q: How can teams reduce risk when AI tools are connected to enterprise workflows?
A: Start by narrowing what the AI tool can see and do, then add monitoring for unusual access patterns and action chains.
Practitioner guidance
- Define tool-level permission boundaries Map every tool, connector, and data source a reasoning model can reach, then scope access separately for read, write, search, and execution actions.
- Route simple tasks away from reasoning models Reserve high-compute reasoning models for genuinely multi-step work and send summarisation, translation, and lookup tasks to cheaper bounded models.
- Add approval gates around external actions Require explicit review before a model can send messages, modify records, or trigger downstream workflows, especially after multi-step reasoning.
Bottom line: Reasoning LLMs improve multi-step task performance by spending more compute on internal deliberation, but that creates new governance pressure around access scope.

Reasoning LLMs turn tool use into a runtime identity problem. Once a model can deliberate, choose tools, and sequence actions inside a session, access governance can no longer assume a fixed prompt maps to a fixed behaviour. The relevant control question becomes whether the model's runtime authority is bounded tightly enough for the task, not whether the model can answer accurately. Practitioner conclusion: model access and tool access must be governed together.
A few things that frame the scale:
- DeepSeek alone generated 113,000 new exposed API keys in 2025, illustrating how new AI providers create credential exposure before security guardrails catch up, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: Should organisations use reasoning models for every AI task?
A: No. Reasoning models are best reserved for problems where accuracy matters more than speed or cost, such as multi-step analysis, planning, and complex tool use. Simple tasks should stay on faster models, because added inference does not create value when the task is already straightforward.
