Try DeepSeek V4 Pro in the playground
DeepSeek V4 Pro is the catalog's flagship heavy-reasoning model: contract analysis, code review on an existing codebase, summarizing a financial report, anything that needs to hold several constraints in mind across a long answer. It's only available from the Pro plan up, and its 160k window absorbs a full document.
Against Qwen3.7 Max, its direct competitor at the same Pro tier and a very close price, the choice mostly comes down to context: Qwen3.7 Max reaches 256k where DeepSeek V4 Pro stops at 160k, which matters for a very large document. Against DeepSeek V4 Flash, its cheaper sibling in the same family, the difference is much more reliable reasoning at a noticeably higher cost per token.
It is not the right choice for high-volume chat or repeated short answers: the cost climbs fast without the extra quality being put to use, and DeepSeek V4 Flash covers that case for a fraction of the price. It's also not a coding-agent specialist: Kimi K2.6 is built specifically for autonomous development sessions.
