Dispatch tier: Expensive (complexity class this model is routed for)
Real workhorse volume (274 runs) and ~72% success once you forgive the 27 infra-lost runs — but it burns 2.4M tokens per job to match what kimi-k2p7 does on half the budget. Solid, not thrifty.

Outcomes
Status breakdown
Every run ends in exactly one status. The bar is the whole record, to scale.
- failure: 64 of 274 runs (23.4% of total)
- killed: 1 of 274 runs (0.4% of total)
- timeout: 4 of 274 runs (1.5% of total)
- lost: 27 of 274 runs (9.9% of total)

Commentary
Idiosyncrasies
What stands out in this model's numbers — shape, appetite, and failure habits.
- The fleet’s biggest eater at volume: ~3.8M tokens in and ~28k out per token-measured run, at ~$3.40 per metered run — 11x deepseek-v4-pro.
- Bimodal by the clock: p25 is 28 seconds but the median is over 6 minutes — runs either bail almost immediately or settle in for a grind.
- 65% success at 274 runs — no measured rate premium over workhorses costing a tenth as much; 27 infra-lost runs pad the failure column.
Commentary
Lessons learned
Practical routing and operations takeaways, grounded in the same record.
- The record does not show the expensive tier buying a higher success rate here — route it work the cheap tiers already failed, not first attempts.
- The half-minute p25 suggests many runs die before doing real work; cheap pre-flight checks would save real money at $3.40 a pop.
