What are the verified coding and reasoning benchmarks for O3 Mini 2025 01 31?

O3 Mini 2025 01 31 achieves SWE-bench Verified: 49.3% (High Reasoning (Baseline)), LiveCodeBench: 69.5%, AIME: 87.3%. Verified sources: OpenAI o3-mini System Card & Announcement (OpenAI).

Does Swarm isolate O3 Mini 2025 01 31 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 O3 Mini 2025 01 31 be assigned to specific subagent roles?

Yes. In ~/.swarm/config.json, you can configure O3 Mini 2025 01 31 as Primary/Planner (DAG task decomposition), Coder (implementation in isolated worktrees), or Finder (read-only symbol search).

O3 Mini 2025 01 31 — Specs, Context & Capabilities

Q: What is the recommended Swarm multi-agent topology for O3 Mini 2025 01 31?

Swarm recommends O3 Mini 2025 01 31 as Coder Subagent (Tier 2: Dedicated Logic & Test Engineer). Excels at writing comprehensive unit test suites and verifying complex boundary conditions before code merges. Perfect for Stage 2 integration barriers in Task Programs. Best paired with: Claude 3.7 Sonnet as Planner or Gemini 3.8 Flash as Finder.

Q: How do I run O3 Mini 2025 01 31 with Swarm?

Configure O3 Mini 2025 01 31 via CLI using: swarm ctl model set --provider openai --model openai/o3-mini-2025-01-31, or switch models interactively inside the terminal TUI with /models.

Git Worktree Isolation Advantage:

Because o3-mini produces highly deterministic logic patches, running it inside isolated Git worktrees guarantees clean test assertion commits with zero branch pollution.

What Developers & Practitioners Are Saying

Real-world field observations, production strengths, and developer consensus

Field Consensus

"The gold standard for developer price-to-performance in reasoning models. Blazingly fast compared to o1, offering frontier STEM deduction at utility rates."

Verified Real-World Strengths

Top-tier LiveCodeBench (52.6%) and AIME (79.2%) for just $1.10/M input
High throughput for a reasoning model
Excellent for isolated algorithmic modules, regex authoring, and SQL tuning

Production Caveats & Gaps

Context window smaller than Gemini (200k vs 1M+)
Can overthink simple string formatting or file listing tasks
Lacks multimodal image inputs
