**GPT-5.4: COMPLETED** ✅ (2 min 21 sec)
**Kimi K2.6: FAILED** ❌ (timed out after ~5.5 min, returncode 124)

That's already a significant difference — Kimi couldn't finish the same prompt that GPT-5.4 handled in under 2.5 minutes. Let me fetch the actual outputs:## Subagent Comparison Results

| | **GPT-5.4** | **Kimi K2.6** |
|---|---|---|
| **Status** | ✅ Completed | ❌ Failed (timeout) |
| **Duration** | ~2 min 21 sec | ~5 min 30 sec (timed out) |
| **Return code** | 0 | 124 |

### What happened

**GPT-5.4** — Completed successfully with a thorough, well-structured response covering:
- Specific diagnosis (Python bridge = spike source, Synapse = steady state, PostgreSQL = multiplier)
- Concrete config values (`MemoryHigh=900M`, `shared_buffers=512MB`, `event_cache_size: 5K`, etc.)
- Step-by-step prioritization with rationale
- Practical fixes without generic "add more RAM" advice

**Kimi K2.6** — Started thinking, issued some bash commands, then got stuck at `session/request_permission (running)` and timed out after 300 seconds. Never produced a result.

### Key takeaways

1. **Speed:** GPT-5.4 was ~2.5x faster and actually finished
2. **Reliability:** Kimi subagents still have permission/timeout issues in the ACP harness
3. **Quality:** GPT-5.4's output was detailed, actionable, and followed the prompt structure closely
4. **The permission problem:** Kimi got stuck waiting for tool call approvals — this suggests the non-interactive permissions issue still affects subagents

### Verdict

For subagent work, **GPT-5.4 is currently more reliable** — it completes faster and doesn't get stuck on permissions. The quality of output was also very good with detailed, specific advice.

However, the cost comparison still matters: if you're running many subagent tasks, GPT-5.4 will be more expensive per task. But for reliability-critical background work, it might be worth it.

Want me to try a different prompt with Kimi (maybe shorter/simpler) to see if it can complete, or are you satisfied with this comparison?
