[Bug] Opencode wont start with this plugin 1.14.46

Using opencode v1.14.46, startup fails

13:14:31 [ajaym] in ~/.config/opencode  oc
Error: 1 of 5 requests failed: config.get: opencode server GET http://opencode.internal/config?directory=%2FUsers%2Fuser%2F.config%2Fopencode → 400: (empty response body)

I receive a similar error, when I try to start opencode TUI:

Error: 1 of 5 requests failed: config.get: Expected "text" | "audio" | "image" | "video" | "pdf", got "embedding"
  at ["provider"]["lmstudio"]["models"]["text-embedding-nomic-embed-text-v1_5"]["modalities"]["output"][0]

TLDR: claude thinks it's because i have an embedding model hosted on lm studio as well, and when opencode or this plugin do model discovery, the model is exposed with the modality embedding - but opencode only accepts "text" | "audio" | "image" | "video" | "pdf", got "embedding".
it is unclear why this happens now, but the working theory is that while opencode never accepted embedding as a value here, it also didnt enforce it (but does now).

trying to throw out nomic as a quick fix now, but i think it's included with lm-studio per default? the other fast pathway would be to not use this plugin and hardcode the models instead of doing discovery.

Summary

After updating opencode from 1.14.30 to 1.14.46, the plugin causes opencode to fail startup with an HTTP 400 on GET /config because it registers embedding-only models (e.g. text-embedding-nomic-embed-text-v1.5) with modalities.output: ["embedding"], which is not an accepted value in opencode's config schema.

This worked fine on 1.14.30. opencode 1.14.47 notes "HTTP API schema validation errors now return a readable 400 response body" — i.e. the schema was already strict, but is now actively enforced/surfaced. The plugin itself hasn't changed (npm shows 0.3.0 from ~5 months ago); the breakage is triggered by opencode tightening validation.

Error

From ~/.local/share/opencode/log/:

service=default http.method=GET http.url=/config http.status=400 cause=HttpApiSchemaError: Body {
  [cause]: SchemaError: Expected "text" | "audio" | "image" | "video" | "pdf", got "embedding"
    at ["provider"]["lmstudio"]["models"]["text-embedding-nomic-embed-text-v1_5"]["modalities"]["output"][0]
}

The TUI shows:

Error: 1 of 5 requests failed: config.get: opencode server GET http://opencode.internal/config?directory=... → 400: (empty response body)

opencode does not start.

Reproduction

1. opencode 1.14.46 (also reproduces on 1.14.47)
2. opencode-lmstudio 0.3.0 enabled as a plugin
3. LM Studio running on 127.0.0.1:1234 with an embedding model loaded (e.g. nomic-embed-text-v1.5) alongside chat models
4. Run opencode in any project directory

Minimal config:

{
  "$schema": "https://opencode.ai/config.json",
  "plugin": ["opencode-lmstudio"],
  "provider": {
    "lmstudio": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "LM Studio (local)",
      "options": { "baseURL": "http://127.0.0.1:1234/v1" }
    }
  }
}

Expected behavior

opencode starts. Embedding models exposed by LM Studio should either be filtered out (they're not usable as a chat/coding agent target) or registered without a modalities field — opencode's schema currently only accepts text | audio | image | video | pdf as output modalities.

Suggested fix

In the model categorization / config-merge logic (the same area as #7), detect embedding models from LM Studio's /v1/models response and either:

• skip them entirely when populating provider.lmstudio.models, or
• emit them without modalities (or with an empty/omitted modalities.output) so the schema validator doesn't reject them.

LM Studio tags embedding models clearly in /v1/models (type: "embeddings" on the newer API, or model name prefix text-embedding-* as a fallback), so the filter is straightforward.

Workaround

Ejecting the embedding model in LM Studio, or downgrading opencode to 1.14.30, both make startup succeed. Neither is desirable long-term — embeddings in LM Studio are useful for other tools, and pinning opencode means missing fixes.

Environment

• opencode 1.14.46 (also 1.14.47)
• opencode-lmstudio 0.3.0
• LM Studio (latest), serving on 127.0.0.1:1234
• macOS, bun runtime (as bundled with opencode)

Happy to test a patch.
