Feature Comparison Matrix
Direct evaluation criteria and performance indicators.
| Comparison Metric | DeepSeek R1 | OpenAI o1 | Winner |
|---|---|---|---|
| Weights Availability | Open Weights (Full 671B MoE + 1.5B to 70B Distillations) | Proprietary Cloud API Only | DeepSeek R1 |
| API Token Pricing (Input / Output) | $0.55 / $2.19 per 1M tokens | $15.00 / $60.00 per 1M tokens | DeepSeek R1 (27x Lower Cost) |
| Local Execution (Ollama / vLLM) | Supported on Linux workstations and Apple Silicon | Not Supported | DeepSeek R1 |
| Code Generation Accuracy (HumanEval / SWE-bench) | Comparable (90.8% Pass@1 on HumanEval) | Leading (92.4% Pass@1 on HumanEval) | OpenAI o1 |
| Reasoning Visibility | Full access to explicit <think> token sequences | Summarized chain-of-thought (raw tokens hidden) | DeepSeek R1 |
Why choose DeepSeek R1?
- ✓Open-weights architecture allows zero-cloud air-gapped local execution
- ✓27x lower API cost for high-throughput production reasoning loops
- ✓Full access to raw thinking tokens for advanced agent verification
Why choose OpenAI o1?
- ✓Slightly higher raw accuracy on complex competitive programming benchmarks
- ✓Managed cloud infrastructure with zero local hardware provisioning
- ✓Direct integration into OpenAI ecosystem tooling
The Lab Verdict
Choose DeepSeek R1 if you require local air-gapped deployment, transparent thinking token access, or high-volume agent loops at a fraction of API cost. Choose OpenAI o1 if your workflow depends on managed cloud endpoints with maximum competitive programming scores.
