The default provider comparison pools\nmeasurements from every completed run for the model. Each run keeps its\nbenchmark version in SQLite so methodology changes remain auditable without\nremoving older completed measurements from the aggregate.\n\nBefore each run, the worker fetches Vercel's live endpoint catalog. It\nbenchmarks every returned provider and stores a normalized provider snapshot.\nProviders newly added by Vercel are included automatically. An interrupted run\nresumes against the exact provider set it started with.\n\nEach provider receives the same fixed multi-turn message array four times.\nAttempts for one provider run sequentially to preserve the cache warmup signal,\nwhile different providers run concurrently. Gateway automatic caching is\nenabled and each request is restricted to the provider being measured.\n\n## Routing strategies\n\nAlongside the solo providers (`only: [provider]`), the run also benchmarks\nfive synthetic \"strategy\" endpoints defined in `benchmark/strategies.ts`. They\nexercise the gateway's own routing instead of pinning a provider:\n\n| Row | `providerOptions.gateway` |\n|-----|---------------------------|\n| Gateway default | no hints — gateway picks by recent uptime + latency |\n| Sort by TTFT | `sort: \"ttft\"` |\n| Sort by throughput | `sort: \"tps\"` |\n| Handpicked only | `only: [modal, wafer, particle]`, `order: [modal, wafer, particle]` |\n| Prefer handpicked | `order: [modal, wafer, particle]` — falls back to any other provider |\n\nEvery strategy also sends `zeroDataRetention: true` and\n`disallowPromptTraining: true`, so the gateway only routes to providers with\nno-store / no-train agreements. Those flags are shown per provider in the\n**No store** / **No train** columns, read from `has_zdr` / `has_no_training`\nin Vercel's endpoint catalogue.\n\nFor strategy rows the table also shows which provider the gateway actually\nserved from (`providerMetadata.gateway.routing.finalProvider`) and how many\nsuccessful requests needed a failover (`totalProviderAttemptCount > 1`). TTFT\nfor a strategy row therefore includes any retry time — the true cost of\nautorouting.\n\n## Known caveat: reasoning burns the token budget\n\n`deepseek-v4.1-flash` is a reasoning model and the benchmark caps output at\n300 tokens. Every `no_text` error has exactly 300 output tokens: the provider\nenabled reasoning by default, the model spent the whole budget thinking, and\nnever emitted text. Providers that don't emit reasoning (wafer, modal,\ndeepinfra) look ~99% reliable; ones that do (novita, deepseek, gmicloud,\nparticle) look 75–87%. It also inflates tokens/sec for reasoning providers,\nbecause all 300 tokens are divided by the tiny window after first text.\nFixing this (higher cap, or disabling reasoning) is a benchmark-version change.\n\nThe sortable provider table reports:\n\n- Reliability across all attempts.\n- TTFT p50 and p95 across successful responses.\n- p50 and p5 observed output tokens per second after first text.\n- Cache hits among eligible repeated successful responses.\n- Observed cost per million input plus output tokens.\n\nTokens/sec is output tokens divided by `duration - TTFT`. It measures how\nquickly text reaches this client after the first text delta. Providers that\nbuffer output into a few large chunks can therefore appear unusually fast.\np50 is the median, TTFT p95 is the slow latency tail, and tokens/sec p5 is the\nslow throughput tail.\n\n$/MTok is total observed cost divided by total input plus output tokens,\nmultiplied by one million. Cached tokens remain part of input tokens, while\ntheir discount is reflected in observed cost.\n\nThe measurements page exposes Success and Error. Success is based on the\ncomplete consumed text stream, independent of the bounded private response\npreview. Error rows show a short, redacted message; timeouts include the\nconfigured 75 second limit. Raw response text and provider metadata remain\nprivate.\n\n## Schedule and recovery\n\n`benchmark/scheduled.ts` runs every 15 minutes in UTC. Requests have a\n75 second timeout and automatic SDK retries are disabled.\n\nA renewable SQLite lease prevents scheduled and manual starts from\noverlapping. The lease can be reclaimed after five minutes without a renewal,\nso an interrupted invocation does not block several later intervals.\nIndividual attempts are checkpointed, and a later invocation resumes the same\nbenchmark version without duplicating stored measurements.\n\nTo run manually, edit `benchmark/config.ts` if needed, open\n`benchmark/scheduled.ts` in Val Town, and click **Run**. Public visitors cannot\nstart model requests from the HTTP app.\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.\n\n## Structure\n\n- `benchmark/prompt.ts` — fixed messages and benchmark version.\n- `benchmark/attempt.ts` — one streamed AI SDK request.\n- `benchmark/measurement.ts` — pure observation-to-row conversion.\n- `benchmark/endpoints.ts` — live Gateway provider discovery.\n- `benchmark/strategies.ts` — synthetic routing-strategy endpoints.\n- `benchmark/lease.ts` — renewable execution lease.\n- `benchmark/execute.ts` — benchmark orchestration.\n- `db/` — val-scoped SQLite schema, writes, provider snapshots, and aggregation.\n- `frontend/` — React interface styled with Twind.\n- `shared/` — shared benchmark and result types.\n",[173],"debdb676-bc1a-41da-9aed-3b08c5132f69","AGENTS.md","81dba77c-ad6f-11f1-bc49-1607ee4eb77e",38,["D",1789484890661],"# deepseek-v41-flash-benchmark\n\nGateway provider benchmark for `deepseek/deepseek-v4.1-flash` through Vercel AI\nGateway. Remixed from `valdottown/glm53-flash-benchmark` with the model id and\nUI copy switched to DeepSeek. Diverges from upstream by also benchmarking gateway\nrouting strategies (`benchmark/strategies.ts`) and showing ZDR / no-train flags.\n\nGotchas:\n- `no_text` errors = reasoning ate the 300-token `maxOutputTokens` budget (see README caveat).\n- Routing metadata lives in `provider_metadata_json` → `$.gateway.routing.{finalProvider,totalProviderAttemptCount,planningReasoning,sort}`. Only present on successful attempts.\n- Request-level `zeroDataRetention` requires a Vercel Pro/Enterprise plan — confirmed working on this key.\n\n## File map\n\n| Path | Type | Purpose |\n|------|------|---------|\n| `index.ts` | http | Hono read-only app (`/`, `/measurements`, `/api/results`, `/api/measurements`) |\n| `benchmark/config.ts` | script | **Model + run config** — change `modelId` here |\n| `benchmark/prompt.ts` | script | Fixed multi-turn messages, `BENCHMARK_VERSION` |\n| `benchmark/attempt.ts` | script | One streamed AI SDK request |\n| `benchmark/measurement.ts` | script | Pure observation-to-row conversion |\n| `benchmark/endpoints.ts` | script | Live Gateway provider discovery |\n| `benchmark/strategies.ts` | script | Synthetic `gateway:*` routing-strategy endpoints (ZDR + no-train flags, handpicked set) |\n| `benchmark/lease.ts` | script | Renewable execution lease |\n| `benchmark/execute.ts` | script | Benchmark orchestration |\n| `benchmark/scheduled.ts` | interval | Cron entrypoint — runs every 15 min UTC |\n| `db/schema.ts` | script | SQLite schema + `sqlite` export |\n| `db/queries.ts` | script | Run/measurement writes and lookups |\n| `db/results.ts` | script | Aggregate provider comparison query |\n| `db/measurements.ts` | script | Paginated measurements listing |\n| `frontend/root.tsx` | script | HTML shell + title/meta |\n| `frontend/index.tsx` | script | Client entrypoint, page switch |\n| `frontend/components/App.tsx` | script | Model header + provider table view |\n| `frontend/components/ProviderTable.tsx` | script | Sortable provider table (used twice: strategies + providers) |\n| `frontend/components/StrategyCells.tsx` | script | No store / No train ✓ cells, routing summary under strategy names |\n| `frontend/components/MeasurementsPage.tsx` | script | Measurements page |\n| `frontend/components/Sparkline.tsx` | script | History sparklines |\n| `frontend/components/InfoPopover.tsx` | script | Column explainers |\n| `frontend/{providers,history,format}.ts` | script | Provider names, hourly series, formatters |\n| `frontend/favicon.svg` | file | Favicon (still the GLM-era glyph) |\n| `shared/types.ts` | script | Shared benchmark/result types |\n| `README.md` | file | Overview + schedule docs |\n\n## Credential\n\n`VERCEL_AI_GATEWAY_API_KEY` (scoped env var).
