DeepSeek R1 wins on price ($0.55 vs $2.5/1M input). GPT-5.4 wins on coding (90 vs 84) and writing quality and context window (272K vs 128K). For most workflows, GPT-5.4 is the stronger default — best for agentic automation and desktop control workflows.
Pick GPT-5.4 for coding and research. Pick DeepSeek R1 when math.
Best for agentic automation and desktop control workflows.
Use GPT-5.4 if you want the strongest default. Switch only when cost, speed, or context length matters more than maximum reliability.
The shortest way to see the safest default, the lower-cost option, and the specialist pick before you read deeper.
GPT-5.4 is the safest overall answer here when you want the strongest default instead of the lowest list price.
Grok 4 is the lower-cost option to start with when you still need useful output at scale.
DeepSeek R1 is the better pick when response speed matters more than maximum reasoning depth.
GPT-5.4 leads on coding with a score of 90 vs 84 for DeepSeek R1.
GPT-5.4 has the larger context window: 272K vs 128K for DeepSeek R1.
DeepSeek R1 is cheaper at $0.55/1M input tokens vs $2.5/1M for GPT-5.4.
Choose GPT-5.4 for coding and research — agentic workflows.
Choose DeepSeek R1 when math.
DeepSeek R1 is the more cost-efficient option at $0.55/1M — worth considering if token volume is a concern.
This comparison focuses on the models most likely to answer this search intent well, not every model in the directory.
Open-source o1-class reasoning at a fraction of the cost.
Best for agentic automation and desktop control workflows.
Use these cards as the practical decision layer: what each leading option is good at, and when it becomes the wrong default.

You need the highest coding benchmark scores — Claude Opus 4.6 and Sonnet 4.6 lead SWE-bench.
UseRightAI recommendations are based on practical decision factors people actually feel in day-to-day use.
Benchmark scores from SWE-bench (coding), ARC-AGI-2 (reasoning), and MMLU (knowledge breadth) — cross-referenced against Chatbot Arena community votes to filter out cherry-picked provider claims.
Input and output costs verified directly against each provider's official API pricing page. Updated whenever a price change is detected. Value-per-dollar is weighted separately from raw benchmark rank.
Advertised context sizes are noted but scored against real-world usability — models that degrade significantly at large contexts are penalised even if the window is technically available.
Production signals matter more than lab scores. We weight Cursor and Windsurf defaults, HackerNews sentiment, developer surveys, and which models teams actually keep using after the honeymoon period.
One-off wins on cherry-picked benchmarks don't move our rankings. We favour models that stay dependable across repeated prompts, diverse task types, and long sessions without degrading.
Time-to-first-token and output throughput from Artificial Analysis speed benchmarks. Latency is categorised from Very fast to Deliberate — relevant when building interactive or high-throughput products.
