deepseek

deepseekPreset() in tui/internal/preset/preset.go uses the shared OpenAI-compatible text shape: provider deepseek, default model deepseek-v4-pro, https://api.deepseek.com, and DEEPSEEK_API_KEY. The shipped manifest has no vision capability, so this manual records no direct image route and no DeepSeek plan-level vision MCP.

Template-specific settings

Read the official DeepSeek API introduction when checking current models, protocol, or limits. For an image request, report that this preset's shipped wiring is text-only and let the agent discover an explicitly chosen skill if one exists; do not guess credentials, switch providers, or auto-load/invoke an MCP. Verify the provider/model/endpoint/env-var fields in TUI source after a template change.

The deepseek preset's base_url offers three options in the TUI preset editor (ProviderRegionURLs["deepseek"]):

• DeepSeek API — https://api.deepseek.com, DEEPSEEK_API_KEY

(the template default).

• OpenCode Go — https://opencode.ai/zen/go/v1, OPENCODE_GO_API_KEY.

This option is scoped to DeepSeek models served through the OpenCode Go subscription: the preset keeps provider: deepseek and the model row stays on the DeepSeek lineup (deepseek-v4-pro / deepseek-v4-flash, both served by /zen/go/v1). The zhipu, minimax, mimo, kimi, and grok presets carry their own OpenCode Go base_url row (same URL, same OPENCODE_GO_API_KEY slot) — route GLM, MiniMax, MiMo, Kimi, and Grok through those, not through this one. For the remaining Go models (gpt-5.6-luna, qwen, ...) create a Custom preset instead, where the model row is free-text and wire_api stays selectable. See the official OpenCode Go docs. China-hosted deepseek-v4-flash requires opting in at the OpenCode workspace page before first use.

• Custom — free-typed endpoint. The editor leaves api_key_env alone on

this row, and a saved edited built-in gets stampAutoEnvVar's numbered slot. To change the slot name itself, edit the preset JSON.

Selecting the DeepSeek API or OpenCode Go option also switches api_key_env to the matching slot in the editor. Saving an edited built-in keeps that slot only for OpenCode Go, whose credential is a shared cross-provider account (the same OPENCODE_GO_API_KEY the zhipu and minimax presets use). On the DeepSeek API row the saved preset gets its own numbered slot instead — DEEPSEEK_1_API_KEY, DEEPSEEK_2_API_KEY, ... — because DEEPSEEK_API_KEY is the template's shared slot, and keeping it would let a second deepseek preset overwrite the first one's key.
