  "abstract": "Generating game art through somebody else's API is easy until you read the terms, price it at volume, or need the same prompt to give the same result in six months. Homeforge runs the whole thing locally instead. This session covers why: ownership, cost at volume, reproducibility, and not having a supplier change the model underneath you. It covers what that actually takes in hardware and wall-clock time, and the cases where the local answer is the wrong one.",
  "summary": "The session argues that owning the entire generation pipeline on a single machine offers ownership, reproducibility, and reduced supplier risk, but it comes with a steady engineering burden and limited elasticity. Key points include a concrete baseline (one workstation with an 8 GB GPU, hundreds of gigabytes of model files, and a 2.2 GB finished library for 232 games), concrete throughput timings (about 1h40m for a complete animated title, ~15 minutes for a static concept, and a full library maintenance pass in a day), and the hidden costs of tooling, memory management, retries, and automated quality gates that keep the pipeline reliable. The talk also notes limitations (small-memory models, quality ceilings on hands/faces/text, lack of burst capacity, and the need for human audits) and contrasts when a hosted API makes sense (low/spiky volume, need for top-quality hero assets, on-demand elasticity, or no team ownership of infrastructure). Open questions or disagreements center on whether local generation is the right fit for a team given the engineering burden and whether the tradeoffs of ownership and reproducibility outweigh the lack of elasticity, with guidance to use a hosted API in certain scenarios and a decision checklist for evaluating library size, iteration rate, and tooling needs.",
