What are the verified coding and reasoning benchmarks for OpenAI: o3 Pro?

OpenAI: o3 Pro achieves SWE-bench Verified: 71.7% (High Reasoning), LiveCodeBench: 76.2%, AIME: 92.4%. Verified sources: OpenAI o3 Technical Specifications (OpenAI).

How does OpenAI: o3 Pro compare to rival frontier coding models on SWE-bench and pricing?

OpenAI: o3 Pro achieves SWE-bench Verified: 71.7% at $5/$20 per 1M tokens. Direct peer comparison: Gemini 3.1 Pro Preview (71% SWE-bench, $2.5/$10); Claude 3.7 Sonnet (70.3% SWE-bench, $3/$15); xAI Grok 4.20 (58.5% SWE-bench, $2/$8); OpenAI GPT-5 (69.5% SWE-bench, $2.5/$10).

Does Swarm isolate OpenAI: o3 Pro code edits from other agents?

Yes. Swarm provisions isolated Git worktrees for every session and subagent, preventing file race conditions and keeping your main working tree clean until verification passes.

Can OpenAI: o3 Pro be assigned to specific subagent roles?

Yes. In ~/.swarm/config.json, you can configure OpenAI: o3 Pro as Primary/Planner (DAG task decomposition), Coder (implementation in isolated worktrees), or Finder (read-only symbol search).

Q: What is the recommended Swarm multi-agent topology for OpenAI: o3 Pro?

Swarm recommends OpenAI: o3 Pro as Primary / Planner (Tier 1: Frontier Architect & Deductive Specialist). Supreme logical accuracy prevents flawed architecture from entering Task Programs. Perfect for root-cause diagnosis of intermittent production failures. Best paired with: Gemini 3.8 Flash for fast subagent implementation.

Q: How do I run OpenAI: o3 Pro with Swarm?

Configure OpenAI: o3 Pro via CLI using: swarm ctl model set --provider openrouter --model openrouter/openai/o3-pro, or switch models interactively inside the terminal TUI with /models.

The o-series of models are trained with reinforcement learning to think before they answer and perform complex reasoning. The o3-pro model uses more compute to think harder and provide consistently...
