DeepSeek-v4-flash-free model missing from OpenCode's Zen provider dropdown despite existing in /zen/v1/models API #43805

This issue might be a duplicate of or related to existing issues. Please check:

• Custom provider models missing from /model TUI picker provider sections in 1.18.10 — caused by recents filter #40592: Custom provider models missing from /model TUI picker provider sections — also reports models missing from the picker dropdown, though the root cause there is a recents filter affecting custom providers. The symptoms are similar; it may be worth reviewing that issue to see if the same mechanism could apply here.

Tried deleting ~/.cache/opencode/models.json as recommended in #40592 — did not resolve the issue. deepseek-v4-flash-free is 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 opencode provider section of the picker. Different root cause, same symptom.

@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-free is 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:

• Ox Alpha Free
• Muse Spark 1.2 Contributor Free
• And several others

We recommend updating OpenCode to the latest version for the best experience with Ox Alpha, then selecting it through /models.

The paid deepseek-v4-flash model also remains available through OpenCode Zen. See the Zen documentation for the current model list and applicable data terms.

Noted. Thanks!

That's a shame. Thanks for the heads-up!

they have removed DeepSeek V4 Flash Free as the promotional offer ended. you can get it back by subscribing to Zen go

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-pickle and deepseek-v4-flash-free are 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 for big-pickle under the opencode provider (cost 0/0, context 200000, no alpha/deprecated status) — so it's not a missing-catalog-data issue.
• Neither model appears in the Desktop app's picker (confirmed via manual scroll and exact-name search for both "pickle" and "deepseek").
• Instead the picker shows ~20 other opencode/Zen models that are not enabled for this account at all.
• Persists after a full process kill (Task Manager, all 6-7 OpenCode.exe instances) + relaunch, and across the 1.18.23 → 1.18.29 auto-update.

So this looks like the same root cause tracked in #40524 (client catalog not reconciled with authenticated /models endpoint), just reproducible with a different model pair. Happy to provide full config/log excerpts if useful.
