DeepSeek models

Introduction

DeepSeek makes the V4 and V4.1 models in two sizes: Flash, the fast and cheap one, and Pro. On 2026-10-27 the free OpenCode model was a free variant of V4.1 Flash. The paid models run in OpenCode through an OpenRouter key.

Ids in OpenCode

With an OpenRouter key, the V4 and V4.1 ids:

opencode models | grep '^openrouter/deepseek/deepseek-v4'

openrouter/deepseek/deepseek-v4-flash openrouter/deepseek/deepseek-v4-flash-0731 openrouter/deepseek/deepseek-v4-flash-vision-exp openrouter/deepseek/deepseek-v4-pro openrouter/deepseek/deepseek-v4-pro-0813 openrouter/deepseek/deepseek-v4.1-flash openrouter/deepseek/deepseek-v4.1-flash-1017

A run on one of them in the OpenCode container: a paid model through OpenRouter.
