MiniMax M2.7 — OpenCode (Ollama Cloud)

Modelfile & provider preset tuned for stable work inside OpenCode over Ollama Cloud.

Background

When using Ollama Cloud models from OpenCode, several issues surface out of the box:

• Stream stalls — the response repeatedly pauses mid-token.
• Stream freezes → timeout — long stalls trip the upstream timeout.
• Same issues on plain HTTP — disabling streaming does not make them go away.
• Reasoning loops — some models (notably DeepSeek) get stuck inside their own reasoning trace and never escape.

The settings below were arrived at empirically and raise the stability of Ollama Cloud + OpenCode to roughly 95%. The remaining edge cases look like Ollama Cloud throughput / model overload bugs, not configuration problems.

⚠️ These settings are experimental. They are not endorsed by Ollama or OpenCode — they are what happened to work best in our environment.

Notes

Why output is set equal to context

Ollama does not honor a separate output (max output tokens) reliably through the OpenAI-compatible surface that @ai-sdk/openai-compatible speaks to. If you set output near 16384 you will see the stream cut off mid-response with no error.

The workaround used here is to make output formally equal to context. The model still decides when to stop on its own; we just stop clipping it on the client side.

Long timeouts

timeout and headerTimeout are bumped to 20 minutes (1200000 ms). Cloud models occasionally queue for several minutes during peak load, and the default AI SDK timeouts will fire long before that.

Why this model, not M3

M2.7 is the smaller / faster sibling of M3 — better when latency matters more than recall. Use it for explore / code-reviewer / qa-engineer agents where you want quick turn-around on a single file or a small diff. For whole-repository reasoning, prefer M3.

Top-k 40

A slightly tighter top-k than other presets in this set — helps M2.7 stay focused on the most relevant tool-call argument values without losing useful diversity.

Reasoning effort — when to pick what

This preset does not declare variants, so the OpenCode reasoning-effort selector will be unavailable for this model. Use the default model selection.

If you want explicit effort control anyway, you can add the standard block — Ollama will ignore unknown values rather than error out:

"variants": {
  "high":   { "reasoningEffort": "high"   },
  "medium": { "reasoningEffort": "medium" },
  "low":    { "reasoningEffort": "low"    },
  "none":   { "reasoningEffort": "none"   }
}
