DeepSeek V3
Open-source frontier model from DeepSeek that matches GPT-4o class performance at a fraction of the cost — the most disruptive budget option for coding and general tasks.
Open-source o1-class reasoning at a fraction of the cost.
Math, science, complex reasoning, and multi-step problem solving at budget cost
Speed matters — R1's deliberate reasoning makes it wrong for interactive or high-throughput use cases.
R1 is a genuine milestone for open-source AI. The reasoning quality is real — the tradeoff is latency, not capability.
o1-class reasoning performance at under $0.60/1M input tokens
Open-source weights — can be self-hosted for sensitive workloads
Explicit chain-of-thought reasoning makes outputs auditable
Slow — deliberate reasoning takes significantly longer than standard models
Overkill for routine tasks where a faster model gets the same result
Same data sovereignty concerns as DeepSeek V3 for regulated industries
What people actually use DeepSeek R1 for.
Complex algorithm design and mathematical problem-solving where chain-of-thought reasoning matters
Scientific research synthesis requiring structured multi-step analysis
Hard coding challenges and competitive programming at low cost compared to o1

Claude 3.5 Sonnet is Anthropic's mid-cycle flagship model, balancing strong reasoning, coding, and instruction-following with a 200K context window. It sits between Haiku and Opus in Anthropic's lineup, offering near-flagship quality at a lower cost than top-tier models.
Claude 3.7 Sonnet with extended thinking enabled — Anthropic's hybrid reasoning model that explicitly deliberates before responding, surfacing its chain-of-thought for complex multi-step problems. It sits between standard Sonnet and full reasoning-only models, balancing depth with practical usability.
DeepSeek R1 is best for math, science, complex reasoning, and multi-step problem solving at budget cost. It is a strong fit when that workflow matters more than the tradeoffs around budget pricing and deliberate speed.
