Best LLM for Reasoning in 2026

When the task is genuinely hard — multi-step reasoning, math, complex analysis — raw model intelligence matters more than price. This ranking is led by the highest-scoring models on the Artificial Analysis Intelligence Index, so you get the sharpest reasoners available on Ofox.

What the score can tell you

Match scores combine catalog data, available benchmark references and heuristics. Quality includes release age. Speed uses throughput data where available and estimates otherwise; it is not measured request latency. Missing benchmarks use model-family heuristics. These are recommendations, not task-specific test results. Catalog updates do not mean the benchmark references have been updated.

Frequently asked questions

How does the Model Finder pick models?+

Text, image and embedding candidates are scored using task-specific rules and available references. Video, speech and transcription candidates are listed by model ID without a comparative score; no cross-modal quality ranking is implied.

Is it free? Do I need an account?+

Yes, it's completely free and runs in your browser — no login or API key needed to get recommendations. You only need an Ofox account when you're ready to actually call a model.

Are these real, up-to-date models?+

Models come from the Ofox catalog. Availability and metadata can change; catalog refreshes do not refresh benchmark references. Check the model detail page before use.

Why doesn't the cheapest model always rank first?+

Unless you pick 'Lowest cost', the finder balances price against quality and capability. A model that costs a little more but is much more capable will often score higher — just like a person would choose.

Can I use the recommended models with my existing code?+

Integration depends on the model and task. Video, speech and transcription can use different endpoints, parameters and billing units. Follow the selected model’s documentation; changing only an API key and base URL may not be enough.
