Grok Burst Lane Cost-Risk Matrix (2026-06-22)

ALIVE: true
Lane: Grok Worker D / UAPI burst provider comparison
Sources: agent-work-queue-v2-unblocked.md; local (grok-cloud-colab-burst-lane-review.md, grok-cloud-gpu-broker-contract-notes.md + priors); public: https://research.google.com/colaboratory/faq.html, https://colab.research.google.com/signup, https://docs.runpod.io/serverless/pricing, https://www.runpod.io/pricing.

Broker Context (from prior)

UAPI lease + artifact handoff only (pre-lease sink inputs; post outputs). Hard caps. Local/lab first. https://docs.runpod.io/serverless/overview

Cost/Auth/Lifecycle/Risk Matrix

Aspect Colab Notebook Burst RunPod Serverless/On-Demand Lab-hosted (NUC 140T/NPU, Cortex)
Cost (marginal) $9.99/100CU; T4~1.5-2CU/h, A100~5-15. Unpredictable burn. ~$0.00019-0.00116/s (A100 equiv ~$2.7/h util). No idle Flex. $0 marginal; amortized hw+power. Cap by inventory.
Predictability Low (fluctuate, exhaust term). High (per-sec + $80/h limit). Highest (fixed).
Auth Google+billing/Drive. Re-init/lease. API keys + vols + endpoints. Internal op-mediated (no cloud keys).
Isolation Paid config only. Per-lane endpoints. Highest (lab bounds).
Lifecycle Ephem VM (idle+12-24h max). Notebook bias. Scale0/Flex/active. Cold (FlashBoot mit). Timeouts. Persistent/reserved. Re-boot post.
Startup/Term Fast connect; high term risk (priority/quota). Cold secs; controlled timeouts. Near-0 or op; low ext risk.
Key Risks Batch disallowed (FAQ); Drive quota; no SLA. Cold cost; image stream; avail. Limited cap; Conductor contention; gate dep.
Exposure/Lock Drive+ephem high lock. Docker portable; sink mit. Lab sinks; lowest lock.

Evidence Required (Pre-Enable)

  1. Isolated paid config/key (UAI rules; never shared).
  2. UAPI hard cost cap + accounting (report deltas; Colab soft insufficient).
  3. Artifact roundtrip (manifest pull + result/logs push).
  4. Synthetic: lease, hard/idle timeout enforce, partial flush, release.
  5. Health: pre-dispatch avail/GPU/store; ongoing via artifacts.
  6. Placement rules + Codex baseline (local/lab > burst on budget).
  7. Fail modes: quota, disconnect, overrun, partial, auth.
  8. Sanitized evidence + operator gate (after local routes).
  9. Broker contract + adapter reviewed.

All: artifact resume; dual timeouts; no provider state.

Assumptions: Artifact sinks durable; small inputs pre-warmed (cold fetch wastes GPU); multi-provider future. Blockers: No configs/keys; contracts absent; no synthetic runs; NUC/SN850X inventory separate. Next: Codex promote matrix + comparison; define adapter evidence checklist; operator gate for isolated config validation only.
