OpenRouter vs Together AI
Broad Provider Access or Capacity Control?
OpenRouter 与 Together AI：广泛接入，还是算力控制？
OpenRouter aggregates access and routes across models and providers. Together AI operates inference products from serverless and batch APIs to dedicated endpoints and model customization. Decide whether the scarce resource is catalog breadth or predictable compute.
OpenRouter 聚合并路由跨模型与供应商的访问；Together AI 运营从无服务器、批处理 API 到专用端点和模型定制的推理产品。应判断稀缺资源是目录广度还是可预测算力。
TL;DR
Choose it for one normalized API, broad model discovery, multi-provider routing, consolidated billing, performance and privacy filters, and fast model switching.
Choose it for hosted open-model inference, serverless and batch consumption, dedicated endpoints, model customization, capacity planning, and infrastructure support.
Measure quantization, context, parameters, throughput, batching, cold behavior, data terms, endpoint lifecycle, and support for the exact SKU.
Exploration and long-tail models can use aggregated access while stable high-volume workloads graduate to controlled or dedicated capacity.
适合统一标准化 API、广泛模型发现、多供应商路由、合并账单、性能/隐私过滤和快速切换模型。
适合托管开放模型推理、无服务器与批处理、专用端点、模型定制、容量规划与基础设施支持。
应测量量化、上下文、参数、吞吐、批处理、冷启动行为、数据条款、端点生命周期和具体 SKU 支持。
探索与长尾模型可使用聚合访问，稳定高流量负载则转入受控或专属容量。
Separate marketplace routing from inference operations 区分市场路由与推理运营
OpenRouter normalizes a provider marketplace. Official documentation describes one API for hundreds of models, provider routing by order, fallback, price, throughput, latency, privacy and data-retention requirements, plus BYOK and consolidated usage.
OpenRouter 标准化供应商市场。官方文档描述一个 API 访问数百模型，并可按顺序、回退、价格、吞吐、延迟、隐私和数据保留要求路由供应商，同时支持 BYOK 与合并用量。
Together AI hosts and operates inference. Its product and documentation surface spans serverless inference, batch processing, dedicated endpoints and clusters, fine-tuning and model deployment. The capacity, lifecycle and utilization contract is therefore central.
Together AI 托管并运营推理。其产品与文档覆盖无服务器 Inference、批处理、专用端点/Cluster、微调与模型部署，因此容量、生命周期和利用率契约是核心。

Choose breadth or capacity deliberately 有意选择广度或容量
Teams need immediate broad access, provider-level routing controls, consolidated billing, long-tail models, and minimal endpoint operations.
A smaller model portfolio requires serverless performance, batch economics, dedicated capacity, fine-tuning, private networking, or tighter lifecycle control.
Discovery and fallback breadth differ from the stable workloads that justify dedicated or customized inference capacity.
团队需要立即获得广泛访问、供应商级路由控制、合并账单、长尾模型且不想运营端点。
较小模型组合需要无服务器性能、批处理经济性、专属容量、微调、私有网络或更强生命周期控制。
发现与回退所需的广度，不同于值得使用专属或定制推理容量的稳定负载。
Route by workload maturity 按工作负载成熟度路由
Classify workloads as exploration, bursty production, predictable production, offline batch, custom model, and regulated/private. Keep a canonical request contract and model capability profile. Use aggregated access where breadth and resilience dominate; promote workloads to hosted or dedicated endpoints only after volume, latency, quality and support evidence justify capacity commitments.
把负载划分为探索、突发生产、可预测生产、离线批处理、自定义模型和受监管/私有。保留规范请求契约与模型能力画像；广度与弹性优先时使用聚合访问，只有当流量、延迟、质量与支持证据证明值得承诺容量时，才把负载升级到托管或专属端点。
Architecture rule: the same model slug must never be assumed to have identical weights, quantization, context, parameters, safety behavior, or performance across endpoints.
架构规则：不要假设同一模型 Slug 在不同端点上具有相同权重、量化、上下文、参数、安全行为或性能。
An access-versus-capacity proof 访问与容量验证
- Select representative chat, tool, structured-output, long-context, embedding, image, and batch tasks.
- Pin exact model and endpoint versions; record quantization, context, supported parameters, data terms, and deprecation policy.
- Measure first-token and total latency, throughput, queueing, cold behavior, error rate, and output quality under real concurrency.
- Force one provider failure and one capacity saturation; verify fallback, request IDs, billing, and recovery evidence.
- Compare cost per accepted task, including idle capacity, batch discount, engineering and support.
- 选择代表性的对话、工具、结构化输出、长上下文、Embedding、图像与批处理任务。
- 固定模型与端点版本，记录量化、上下文、支持参数、数据条款和弃用策略。
- 在真实并发下测量首 Token/总延迟、吞吐、排队、冷启动、错误率与输出质量。
- 强制一次供应商故障与容量饱和，验证回退、请求 ID、账单和恢复证据。
- 比较每个被接受任务的成本，包括闲置容量、批处理折扣、工程与支持。
Migrate the model contract, not just the base URL 迁移模型契约，而不只是基础地址（Base URL）
Export model IDs, provider preferences, fallbacks, privacy settings, keys, credits, rate limits, usage and error traces. Build capability tests for every production model. Dual-run on the target endpoint, reconcile output semantics and cost, then canary by workload. Preserve direct rollback until endpoint lifecycle and support are proven.
导出模型 ID、供应商偏好、回退、隐私设置、密钥、余额、限流、用量和错误追踪；为每个生产模型建立能力测试。在目标端点上双轨运行并核对输出语义与成本，再按负载灰度；在生命周期和支持得到验证前保留直接回滚。
Inference supply and external capabilities remain distinct 推理供给与外部能力仍是不同层
