A 48-Hour Hackathon for High-Volume Model Work

For a team running sustained model workloads, a hackathon should produce more than an impressive demo. It should reveal which internal workflows deserve production investment, what they cost under realistic traffic, and where human review remains necessary. Build the event around a 48-hour window, a fixed spending ceiling, and evidence that another engineer can reproduce.

01 · Step 1: Collect workflows with measurable friction

A week before the event, ask engineering and operations teams to submit repetitive tasks with identifiable owners. Good candidates include incident-summary drafting, support-ticket classification, deployment-note preparation, and extraction from internal documents. Reject proposals that depend on unrestricted production access or cannot explain what a correct result looks like.

Each submission should name the current process, expected workload, acceptance criteria, and consequence of an incorrect answer. Select a small enough shortlist that every team can access domain expertise during the event.

02 · Step 2: Prepare safe, representative test packs

Give each team a versioned dataset containing ordinary cases, difficult cases, and examples where the correct behavior is to abstain or escalate. Remove secrets and unnecessary personal information. Confirm that sending the remaining data to the selected model providers is permitted by company policy.

Keep a held-out portion for final judging. Otherwise, teams can accidentally optimize prompts for familiar examples rather than improve the workflow. For tool-using prototypes, provide read-only access or a sandbox, not credentials that can change production systems.

03 · Step 3: Set shared access and enforce spending limits

Use one access path so teams spend their time testing workflows rather than integrating several providers. Quanta fits this setup naturally: its pay-as-you-go API relay supports multiple model families through one balance and works with existing coding tools and OpenAI SDK clients. Open a Quanta account before the event and validate a minimal request from the environment teams will use.

Set a total event budget, assign team-level allowances, and implement application-side request, concurrency, and token limits. Confirm which controls your tooling actually enforces; a spreadsheet allocation is not a spending stop. Quanta meters calls on real tokens, with cache writes and cache reads priced separately, so capture those categories rather than estimating cost from request counts alone.

04 · Step 4: Build one baseline before exploring models

Start the first morning with the simplest useful implementation: one task, one prompt, one output schema, and explicit failure handling. Compare it with the existing manual process or a deterministic script. A model should earn its place, not receive credit simply for generating plausible text.

Then compare a small candidate set, such as Claude Sonnet 5.5 and DeepSeek V4 Flash, on the same test pack. Record prompt versions, model identifiers, generation settings, latency, token usage, and human corrections. Avoid changing the model and prompt simultaneously; you will lose the ability to explain improvements.

05 · Step 5: Replay the workload, not just the demo

During the second day, replay sanitized requests at the concurrency and input lengths the workflow is likely to encounter. Include bursts, long documents, malformed inputs, timeouts, and retries. Keep load testing within provider policies and your approved budget.

Separate cold-cache and warm-cache runs. Report cache writes and reads independently, and include failed attempts and retries in total consumption. Measure completed, acceptable tasks rather than successful HTTP responses. A cheap request that requires repeated correction may be an expensive workflow.

06 · Step 6: Judge with a scorecard agreed in advance

• › Quality: Performance on held-out cases, including abstentions and costly errors.
• › Economics: Total model spend per accepted task, with review effort reported separately.
• › Operations: Latency, retry behavior, observability, and recovery from dependency failures.
• › Safety: Data boundaries, permission controls, and required human approvals.

Require teams to show failures alongside successes. A polished interface should not outweigh weak evaluation evidence.

07 · Step 7: Fund a bounded pilot, not an automatic rollout

Finish by selecting pilots with named owners, limited traffic, spending caps, and rollback conditions. Preserve the evaluation pack and request logs so later changes can be tested consistently. Schedule a review after representative usage, not merely after a calendar milestone. The hackathon succeeds when it leaves the team with a defensible deployment decision, including the decision not to automate.
