How to Choose the Right AI Model
A practical guide to picking the best LLM for your use case.
Match the model to the task
General-purpose models like GPT-4o and Claude Sonnet handle most tasks well. For specialized work, coding models (DeepSeek Coder, Codestral) and math models (QwQ, DeepSeek R1) outperform generalists on their respective benchmarks while often costing less per token.
Consider context window size
If you work with long documents, codebases, or multi-turn conversations, context window matters. Models range from 8K to over 1M tokens. Larger windows let you process entire books or repositories in a single prompt, but they increase cost and latency.
Balance cost, speed, and quality
Frontier models deliver the highest benchmark scores but cost more per token and respond slower. Fast models like Gemini Flash, Llama 3 (8B), and Mistral Small can handle routine tasks at a fraction of the cost with sub-second latency — ideal for high-volume applications.
Open source vs. proprietary
Open-source models (Llama, Mistral, Qwen, DeepSeek) let you self-host, fine-tune, and inspect weights. Proprietary models (GPT-4o, Claude, Gemini) often lead on benchmarks and offer managed APIs with built-in safety features. Many teams use both: proprietary for peak performance, open source for cost control and customization.
Check for multimodal capabilities
Some models accept images, audio, or files alongside text. If your workflow involves analyzing screenshots, diagrams, or audio transcriptions, filter for models with vision or audio input support. Models with structured output and function calling are essential for building agents and tool-using applications.
Use benchmarks as a starting point
Scores like GPQA, MMLU Pro, and HLE measure academic knowledge and reasoning. LiveCodeBench and SciCode test practical coding ability. MATH 500 and AIME evaluate mathematical problem-solving. No single benchmark tells the full story — compare scores across categories relevant to your use case, then test with your own prompts.
