Reasoning AI Models

259 models on CoreAI support native reasoning — they "think" through a problem step-by-step before answering, which dramatically improves accuracy on math, logic puzzles, competitive coding, and multi-step analysis. Reasoning-capable models are available from Tencent, Inclusionai, Qwen, Z.AI, Meta and more, listed newest-first below.

Reasoning mode trades speed for quality: responses take longer and consume more tokens, but for hard problems the difference is decisive. In CoreAI, models that support thinking show a "Think" chip in chat — tap it to enable deliberate reasoning for that message.

Frequently Asked Questions

What is a reasoning AI model?

A reasoning model generates an internal chain of thought before producing its final answer, checking intermediate steps along the way. This makes it far more reliable at math, logic, planning, and debugging than a model that answers in one pass.

When should I use a reasoning model instead of a normal one?

Use reasoning for problems with a verifiable right answer: math, code that must compile, data analysis, tricky logic. For casual chat, brainstorming, or writing, a standard model is faster and cheaper with no quality loss.

Do reasoning models cost more?

The thinking step generates additional tokens, so a reasoning response consumes more of your usage allowance than a standard reply from the same model. Many providers also price their dedicated reasoning models at a premium tier.

Which providers offer reasoning models in 2026?

On CoreAI, reasoning-capable models currently come from Tencent, Inclusionai, Qwen, Z.AI, Meta and others. The list refreshes automatically as providers ship new thinking models.
