Results pool measurements from every\ncompleted run, so hourly and manual runs update the same comparison.\n\nBefore each new run, the worker fetches Vercel's live endpoint catalog. It\nbenchmarks every returned provider and stores one normalized row per provider\nin `benchmark_provider_snapshots`. A provider newly added by Vercel is\ntherefore included automatically on the next run. The full catalog JSON also\nstays on the run record so an interrupted run can resume against the exact\nprovider set it started with.\n\nThe sortable provider table reports:\n\n- Reliability: responses with visible text divided by attempted requests.\n- TTFT p50 and p95 across usable text responses.\n- p50 and p5 output tokens per second over usable text responses.\n- Cache hits among eligible repeated usable responses.\n- Median observed Gateway cost per usable response.\n\np50 is the median. TTFT p95 is the slow latency tail, while tokens/sec p5 is\nthe slow throughput tail. With fewer than 20 observations, nearest-rank p95 and\np5 are the observed maximum and minimum.\n\n## Schedule\n\n`benchmark/hourly.ts` runs at minute 17 of every hour (UTC). It refreshes the\nprovider catalog, then executes the full benchmark. Requests use a 75 second\ntimeout and disable automatic SDK retries. A recent running benchmark causes\nthe interval to skip; an older interrupted run remains resumable.\n\n## Run manually\n\n1. Edit [benchmark/config.ts](./benchmark/config.ts) if needed.\n2. Open [benchmark/run.ts](./benchmark/run.ts) in Val Town and click **Run**.\n3. Refresh the public page after the benchmark completes.\n\nThe runner checkpoints each attempt. Running the same configuration resumes an\ninterrupted run and skips persisted attempts.\n\n## Access\n\nThe Gateway credential is stored as the encrypted\n`VERCEL_AI_GATEWAY_API_KEY` environment variable. The HTTP app exposes only\nread-only routes, so public visitors cannot start paid model requests.\n\n## Structure\n\n- `benchmark/` — configuration, fixed conversation, manual runner, and hourly interval.\n- `db/` — val-scoped SQLite schema, writes, provider snapshots, and cross-run aggregation.\n- `frontend/` — React interface styled with Twind.\n- `shared/` — shared benchmark and result types.\n",[151],"57180eb9-f846-47ed-9f7f-5ec6aa1d02be","shared","f91bd0d2-a234-11f1-8cec-1607ee4eb77e",4,["D",1787848382634],"directory",[159],"6f24ec24-8f0c-4d0d-b0d3-fbc1bac995ce","frontend","01a04410-0100-7214-ba2d-95062f41a4ba",1,["D",1787848294548],[166],"5e355af5-f49e-4221-87df-a392a9184c4b","db","f73349d0-a234-11f1-922e-1607ee4eb77e",["D",1787848379437],[172],"1d67c685-0a4f-421f-a3c8-63f7187dfcee","benchmark","f52e35aa-a234-11f1-971d-1607ee4eb77e",2,["D",1787848376051],[177],"pulls","branches","forks","envVars",{"_189":168,"_191":64},"connections",{"_189":64,"_190":64},"count","unfilledCount","emptyCount",{"_44":176,"_32":177,"_30":178,"_140":-5,"_42":43,"_41":179,"_142":60,"_39":356,"_13":64,"_34":163,"_36":-5,"_24":25,"_147":-5,"_215":357,"_27":358},{"_44":348,"_32":349,"_30":350,"_140":178,"_42":43,"_41":351,"_142":25,"_39":352,"_13":168,"_34":35,"_36":353,"_24":25,"_147":-5,"_215":354,"_27":355},{"_44":340,"_32":341,"_30":342,"_140":178,"_42":43,"_41":343,"_142":25,"_39":344,"_13":144,"_34":35,"_36":345,"_24":25,"_147":-5,"_215":346,"_27":347},{"_44":331,"_32":332,"_30":333,"_140":178,"_42":43,"_41":334,"_142":25,"_39":335,"_13":168,"_34":336,"_36":337,"_24":25,"_147":-5,"_215":338,"_27":339},{"_44":323,"_32":324,"_30":325,"_140":178,"_42":43,"_41":326,"_142":25,"_39":327,"_13":168,"_34":35,"_36":328,"_24":25,"_147":-5,"_215":329,"_27":330},{"_44":315,"_32":316,"_30":317,"_140":178,"_42":43,"_41":318,"_142":25,"_39":319,"_13":64,"_34":35,"_36":320,"_24":25,"_147":-5,"_215":321,"_27":322},{"_44":171,"_32":172,"_30":173,"_140":-5,"_42":43,"_41":144,"_142":60,"_39":312,"_13":64,"_34":163,"_36":-5,"_24":25,"_147":-5,"_215":313,"_27":314},{"_44":303,"_32":304,"_30":305,"_140":173,"_42":43,"_41":306,"_142":25,"_39":307,"_13":308,"_34":35,"_36":309,"_24":25,"_147":-5,"_215":310,"_27":311},{"_44":294,"_32":295,"_30":296,"_140":173,"_42":43,"_41":297,"_142":25,"_39":298,"_13":299,"_34":35,"_36":300,"_24":25,"_147":-5,"_215":301,"_27":302},{"_44":286,"_32":287,"_30":288,"_140":173,"_42":43,"_41":289,"_142":25,"_39":290,"_13":168,"_34":35,"_36":291,"_24":25,"_147":-5,"_215":292,"_27":293},{"_44":165,"_32":166,"_30":167,"_140":-5,"_42":43,"_41":168,"_142":60,"_39":283,"_13":64,"_34":163,"_36":-5,"_24":25,"_147":-5,"_215":284,"_27":285},{"_44":279,"_32":269,"_30":262,"_140":167,"_42":43,"_41":168,"_142":60,"_39":280,"_13":64,"_34":163,"_36":-5,"_24":25,"_147":-5,"_215":281,"_27":282},{"_44":270,"_32":271,"_30":272,"_140":262,"_42":43,"_41":273,"_142":25,"_39":274,"_13":275,"_34":35,"_36":276,"_24":25,"_147":-5,"_215":277,"_27":278},{"_44":259,"_32":260,"_30":261,"_140":262,"_42":43,"_41":263,"_142":25,"_39":264,"_13":265,"_34":35,"_36":266,"_24":25,"_147":-5,"_215":267,"_27":268},{"_44":252,"_32":253,"_30":254,"_140":167,"_42":43,"_41":168,"_142":60,"_39":255,"_13":64,"_34":20,"_36":256,"_24":25,"_147":-5,"_215":257,"_27":258},{"_44":248,"_32":33,"_30":31,"_140":167,"_42":43,"_41":14,"_142":25,"_39":249,"_13":144,"_34":35,"_36":38,"_24":25,"_147":-5,"_215":250,"_27":251},{"_44":241,"_32":242,"_30":243,"_140":167,"_42":43,"_41":168,"_142":25,"_39":244,"_13":64,"_34":35,"_36":245,"_24":25,"_147":-5,"_215":246,"_27":247},{"_44":233,"_32":234,"_30":235,"_140":167,"_42":43,"_41":236,"_142":60,"_39":237,"_13":144,"_34":35,"_36":238,"_24":25,"_147":-5,"_215":239,"_27":240},{"_44":158,"_32":159,"_30":160,"_140":-5,"_42":43,"_41":161,"_142":60,"_39":230,"_13":64,"_34":163,"_36":-5,"_24":25,"_147":-5,"_215":231,"_27":232},{"_44":221,"_32":222,"_30":223,"_140":160,"_42":43,"_41":224,"_142":25,"_39":225,"_13":226,"_34":35,"_36":227,"_24":25,"_147":-5,"_215":228,"_27":229},{"_44":150,"_32":151,"_30":152,"_140":-5,"_42":43,"_41":153,"_142":25,"_39":218,"_13":155,"_34":20,"_36":156,"_24":25,"_147":-5,"_215":219,"_27":220},{"_44":138,"_32":139,"_30":58,"_140":-5,"_42":43,"_41":141,"_142":25,"_39":214,"_13":144,"_34":145,"_36":146,"_24":25,"_147":148,"_215":216,"_27":217},["D",1787854949956],"children",[],[139],["D",1787855896787],[],[151],"eb0c4bef-4655-4077-bdfa-a0c28f3b3832","types.ts","0553d0c0-a235-11f1-94c6-1607ee4eb77e",111,["D",1787856190167],5,"export
