# Pricing and endpoint (Chat Completions): https://opencode.ai/v2/docs/console/models/ (accessed 2026-10-21).
# Toggle as on the paid deepseek-v4.1-flash route (live: thinking.type = disabled -> 0 reasoning tokens) and DeepSeek's own API; the free tier itself only serves OpenCode clients, so it wasn't probed.
# Toggle: thinking.type = enabled|disabled (not re-verified on Zen: the free tier only serves OpenCode clients)
# Effort: reasoning_effort = low|high|max (not re-verified on Zen: the free tier only serves OpenCode clients)
# Mid-conversation flags (system_updates, effort_updates, tools.updates) follow providers/deepseek/models/deepseek-v4-flash.toml (Zen passes requests through).
# Tools follow DeepSeek's API: https://api-docs.deepseek.com/api/create-chat-completion (tool_choice; strict needs DeepSeek's beta base URL, so it is left out); Zen passes requests through.
