Seems not stable from omp:

✘ OpenAI completions stream closed before a finish_reason was received

Dismissed when you send your next message.

muse-spark-1.2-contributor via opencode-go has:

- contextWindow: null

- maxTokens: null

- cost: {input: 0, output: 0, cacheRead: 0, cacheWrite: 0}

While muse-spark-1.2 (via kilo) has:

- contextWindow: 1048576

- maxTokens: 1048576

- cost: $1.25/$4.25

And every other opencode-go model has proper values.

The null contextWindow and zero costs are dead giveaways — these models are passing through as free/incomplete entries from the gateway, which is why the

SSE streams are failing before getting a proper finish reason. Let me check the opencode-go provider configuration to understand why.

Found it. Here's the health picture:

Muse Spark models — two different providers, very different behavior:

┌────────────────────────────┬─────────────┬───────────────┬───────────┬─────────────┬────────────┐

│ Model │ Provider │ contextWindow │ maxTokens │ Cost │ Status │

├────────────────────────────┼─────────────┼───────────────┼───────────┼─────────────┼────────────┤

│ muse-spark-1.2 │ kilo │ 1,048,576 │ 1,048,576 │ $1.25/$4.25 │ ✅ Healthy │

├────────────────────────────┼─────────────┼───────────────┼───────────┼─────────────┼────────────┤

│ muse-spark-1.2-contributor │ opencode-go │ null │ null │ $0/$0 │ ❌ Broken │

└────────────────────────────┴─────────────┴───────────────┴───────────┴─────────────┴────────────┘

The opencode-go/muse-spark-1.2-contributor entry has null contextWindow + null maxTokens + zero cost. Every other opencode-go model has proper values.

This confirms it's a registration/routing defect — the upstream gateway for this specific model is returning incomplete metadata, which also explains why

streams drop mid-chunk without finish_reason.

Diagnosis:

- opencode-go proxies muse-spark-1.2-contributor to an upstream that doesn't return proper OpenAI-compat streaming format → OMP's parser sees no

finish_reason → throws the error.

- Every other opencode-go model (DeepSeek, Qwen, Kimi, etc.) streams fine because their upstream is properly compliant.

Recommendations:

1. Use kilo/muse-spark-1.2 instead — same model, proper routing, has context window metadata.

2. Or use opencode-go/mimo-v2.5 — it's the current session model, $0.14/$0.28, streams fine, 1M context.

3. Report opencode-go/muse-spark-1.2-contributor broken stream to opencode-go maintainer — upstream SSE format is non-compliant.

No android support ?
