Decision framework
| If you need… | Lean toward |
|---|---|
| Lowest friction daily coding | The tool that matches your IDE and VCS stack |
| Long-horizon refactors | Stronger multi-file / agent features |
| Cost control | Compare Freemium vs Freemium plus inference |
| Compliance | Confirm DPAs before enabling cloud agents |
Many teams pilot both for two weeks on the same ticket sample, then standardize on one primary tool and keep the other for specialized tasks (reviews, migrations, or docs).

DeepSeek
LLM Models · FreemiumDisruptively priced open-weight reasoning models (R1) and general-purpose LLMs (V3). Features chain-of-thought reasoning comparable to o1 at a fraction of the cost.
DeepSeek has disrupted the AI landscape with DeepSeek-R1, an open-weight reasoning model that rivals OpenAI's o1-preview performance in coding and mathematics at a fraction of the cost.
Key Models
1. DeepSeek-R1 (Reasoning)
- Chain-of-Thought: Uses advanced reinforcement learning to "think" before answering, excelling at complex logic and coding tasks.
- Performance: Matches top-tier closed models (GPT-4o, Claude 3.5) on benchmarks like AIME and MATH-500.
- Open Weights: Fully open MIT license, allowing local deployment and fine-tuning.
2. DeepSeek-V3 (General Purpose)
- Efficiency: Uses Multi-Head Latent Attention (MLA) and Mixture-of-Experts (MoE) for extreme inference speed.
- Cost: API costs are approximately 90% lower than comparable frontier models ($0.14/1M input tokens).
- Context: Supports up to 128k context window with efficient caching.
Features
- Context Caching: drastically reduces costs for repetitive tasks.
- Local Deployment: Run R1 locally using Ollama or vLLM.
- API Access: Fully compatible OpenAI-format API for easy integration.
Pricing
- API: Extremely low cost (e.g., $0.14/1M input tokens for V3).
- Open Weights: Free to download and use commercially (MIT License).
