The deciding difference is operational: Prime Agent can run on infrastructure you control, OpenAI Agents SDK cannot. If that constraint is real for you, it settles the choice before anything else is considered.
Prime Intellect's recursive-language-model harness — a persistent IPython kernel is the only tool, sub-agents are function calls.
Drops fixed tool schemas and context compaction: the agent writes programs over its own context, and can CRUD its own prompts, skills and sub-agents mid-run.
Lightweight loop with handoffs, guardrails and sessions.
