Grok Cloud Colab Burst Lane Review (2026-06-22)

ALIVE: true
Lane: Grok Worker A / UAPI cloud/Colab burst
Sources: [REDACTED:high-entropy].md, [REDACTED:high-entropy].md, [REDACTED:high-entropy].md, [REDACTED:high-entropy].md, [REDACTED:high-entropy].md + uapi-grok-hardware-autorouter-cloud-gpu.md; public: https://research.google.com/colaboratory/faq.html, https://colab.research.google.com/signup, https://docs.runpod.io/serverless/overview, https://www.thundercompute.[REDACTED:high-entropy].

Role: Burst/Specialist, Not Control Plane

UAPI owns control plane (PlacementDecision, routing, policy, adapters, run records, artifact refs). Explorer SoT. Conductor handles lanes (master control 706; cloud runbook 707).

cloud.colab.gpu.burst = candidate transient external overflow when local lanes (nuc., cortex.) saturated. Specialist only: not primary, not interactive/low-latency, not control/state. Separate from NUC; own auth/config/cost required.

Auth / Cost / Session Risks

Colab: ephemeral VMs deleted on idle; free max ~12h (varies, not guaranteed). Paid tiers better but still max lifetime + soft limits. https://research.google.com/colaboratory/faq.html

Idle timeouts prioritize interactive notebooks; batch prone to termination. Free disallows some remote/distributed patterns.

Cost (2026): Pro $9.99/mo (100 CU), Pro+ $49.99/mo; paygo $9.99/100 CU. T4 ~1.5-2 CU/hr, A100 ~13-15 CU/hr. Units for runtime+setup; sessions end on exhaust. Unpredictable + cooldown risk. https://colab.research.google.com/signup https://www.thundercompute.[REDACTED:high-entropy]

Auth: Google + billing. No durable UAPI tokens; re-init per lease. Separate config only. GPU type variable (T4 common); Drive quotas; no SLA.

Artifact-First Job Shape

UAPI dispatches via artifact refs + contracts. Burst never gets live control or sessions.

Job = input refs + spec (route=cloud.colab.gpu.burst, params) + timeout + budget + output sink. Broker leases; runtime pulls artifacts, runs, writes results/logs/metrics/manifest to sink. Storage handoff only (no pipe/SSH). Enables audit, retry, lineage. Matches adjacent serverless job patterns (submit/poll/result/scale-zero). https://docs.runpod.io/serverless/overview

UAPI retains PlacementDecision.

Evidence Required Before Enable

  • Isolated paid Colab config (no shared secrets).
  • External hard cost cap + accounting (track/terminate outside provider).
  • Artifact store roundtrip test (pull/push small payloads + results).
  • Synthetic lifecycle: lease, pull, run non-model, timeout enforce, write outputs, observe.
  • Health probe (avail, GPU realized, store latency).
  • Placement fallback rules (local first; burst on overflow+budget).
  • Codex contracts + PlacementDecision baseline. Operator gate.
  • Sanitized evidence promoted; no activation pre other lanes evidence.

Assumptions / Blockers / Next

Assumptions: paid tier; reliable artifact store; synthetic validation precedes real. Blockers: no keys/config; no broker/contract yet; Colab notebook bias + ephemerality (FAQ); contracts unbaselined; SN850X separate. Next: Codex promote this+prior; companion contract notes; handoff+cap evidence before gate.

Report: ALIVE: true | Artifact: [REDACTED:high-entropy].md | Burst as specialist only. Local, read-only, cited public patterns. Next: contract notes + gates. End.
