DeepSeek-v4-flash-free model missing from OpenCode's Zen provider dropdown despite existing in /zen/v1/models API #43805
Description
Description
The deepseek-v4-flash-free model is listed in the Zen API response at https://opencode.ai/zen/v1/models, and is correctly referenced in my opencode.json config ("model": "opencode/deepseek-v4-flash-free"), but it does not appear in the OpenCode TUI's model picker dropdown under the opencode (Zen) provider.
This model should be available for selection, as it exists in the API and is configured as an agent. All other Zen models (e.g., mimo-v2.5-free, nemotron-3-ultra-free) appear correctly in the dropdown, but deepseek-v4-flash-free is missing.
What happened?
When opening the model picker dropdown in OpenCode TUI and filtering by the opencode provider, deepseek-v4-flash-free is not listed, even though:
The Zen API returns it: {"id":"deepseek-v4-flash-free","object":"model","created":1787289055,"owned_by":"opencode"}
It is configured as the orchestrator model: "model": "opencode/deepseek-v4-flash-free"
Other Zen models appear correctly in the same dropdown
Plugins
None installed. Using default OpenCode plugins only.
OpenCode version
v1.18.19
Steps to reproduce
- Open OpenCode TUI
- Trigger model picker (typically ⌘P or via command palette)
- Filter by provider: opencode (Zen)
- Observe that deepseek-v4-flash-free is missing from the list
- Confirm model exists via API: curl https://opencode.ai/zen/v1/models returns {"id":"deepseek-v4-flash-free",...}
Screenshot and/or share link
N/A — this is a model listing issue, not a visual rendering bug. The model simply does not appear in the dropdown despite being valid in the API.

Tried deleting
~/.cache/opencode/models.jsonas recommended in #40592 — did not resolve the issue.deepseek-v4-flash-freeis still absent from the dropdown.Note: #40592 was about custom providers affected by a recents filter. This is a built-in Zen provider model that appears in the API but is missing from the
opencodeprovider section of the picker. Different root cause, same symptom.evsphereofficial commentedon Aug 21, 2026
@MauPeCR I think they removed the model as it says free promotion for DeepSeek V4 Flash Free has ended so it might be gone forever I think

Thanks for the report. The limited-time DeepSeek V4 Flash Free promotion has ended, so
deepseek-v4-flash-freeis no longer available in the model picker. This is intentional rather than a TUI bug.We’ve recently added new free alternatives through OpenCode, including:
We recommend updating OpenCode to the latest version for the best experience with Ox Alpha, then selecting it through
/models.The paid
deepseek-v4-flashmodel also remains available through OpenCode Zen. See the Zen documentation for the current model list and applicable data terms.MauPeCR commentedon Aug 24, 2026
Noted. Thanks!

Adding a data point: this also affects big-pickle, not just deepseek-v4-flash-free.
On OpenCode Desktop 1.18.23 → 1.18.29 (Windows), with a Zen workspace where only
big-pickleanddeepseek-v4-flash-freeare enabled in Model Access:GET https://opencode.ai/zen/v1/models(authenticated) returns exactly these 2 model IDs, nothing else.~/.cache/opencode/models.json(local catalog cache) has a full, valid entry forbig-pickleunder theopencodeprovider (cost 0/0, context 200000, no alpha/deprecated status) — so it's not a missing-catalog-data issue.So this looks like the same root cause tracked in #40524 (client catalog not reconciled with authenticated
/modelsendpoint), just reproducible with a different model pair. Happy to provide full config/log excerpts if useful.thdxr commentedon Oct 11, 2026
Thanks for the report! OpenCode 2.0 is now out and development is focused on V2, so we're closing issues filed against OpenCode 1. Please upgrade (
opencode upgrade --major, details: https://anoma.ly/notes/opencode-2-0), and if this is still relevant on 2.0, reopen this issue or open a new one with your 2.0 version.— from 𝕺𝖕𝖊𝖓𝕮𝖔𝖉𝖊
