## Relace

Relace provides an API-first inference service for open-weight frontier models. Developers sign up, get an API key, and call models such as DeepSeek, Kimi and GLM variants directly, paying only for the tokens they use. All models are billed per token on a pay-as-you-go basis with no subscription or minimum spend, and prompts that reuse a cached prefix are discounted substantially. The company reports serving tens of trillions of tokens per month and consistently ranks among the top providers on OpenRouter, often as the cheapest option for the models it hosts.

Rather than training its own models, Relace focuses on the efficiency of the serving stack — scheduling, batching and GPU utilization — so that it can pass lower costs on to customers. The same models are also reachable through OpenRouter if you prefer a routing layer, while direct access gives you the lowest latency and volume pricing. Team members are reachable by email for large token spenders, GPU partners and hiring conversations.

The product is aimed at developers and companies building AI applications that need reliable, cheap access to strong open models at scale. Because prices are repriced frequently, the rate returned by the API at request time is the one you pay.

**Pricing & Plans:** Pay-as-you-go, per-token pricing with no subscription or minimum. Input, cached input and output tokens are billed separately; volume pricing is available on request. Some model listings may also appear as free on routing platforms.

- **Pay-as-you-go per-token API:** No subscription or minimum commitment — you are billed only for the input, cached input and output tokens you consume.
- **Discounted cached input:** Reusing a cached prefix costs a fraction of the standard input price, which lowers cost for repetitive or agentic workloads.
- **Open-weight frontier models:** Serve popular open models such as DeepSeek, Kimi and GLM families through one consistent endpoint.
- **High-throughput serving stack:** Optimized scheduling and GPU utilization help Relace rank among the top providers by daily token volume on OpenRouter.
- **Direct key or OpenRouter access:** Get an API key for direct low-latency calls, or reach the same models through the OpenRouter routing layer.

**Strengths:** Very competitive per-token pricing, often cheapest for the models served; No subscription or minimum spend — pure pay-as-you-go; Large cached-input discounts reward prompt reuse; High daily token volume and strong OpenRouter rankings suggest reliable scale

**Limitations:** As an open-weight serving provider it does not train or host proprietary frontier models; Pricing changes frequently, so costs can shift over time; The website notes it is updated infrequently, so some marketing pages lag the product

## SiliconFlow

SiliconFlow positions itself as AI infrastructure rather than a single model. The platform aggregates a broad catalog spanning text LLMs, image generation (for example FLUX family), video, and audio models, so teams can switch or compare models by changing one parameter instead of rebuilding an integration. Requests are served through an OpenAI-compatible endpoint, meaning existing SDK code often works with only a base-URL and key swap.

Deployment is flexible by design. Developers can start on Serverless inference with pay-per-use billing and no setup, move to dedicated endpoints for isolation and throughput, or reserve NVIDIA H100/H200, AMD MI300 and RTX 4090 class GPUs when they need guaranteed capacity and predictable billing. An Elastic GPU (FaaS) tier targets bursty or spiky inference workloads, and an AI Gateway layer adds smart routing, rate limiting and cost controls across models.

The platform also covers the surrounding lifecycle: data access and processing, fine-tuning and one-click deployment of customized models, and an inference engine tuned in-house for higher throughput and lower latency. SiliconFlow states that customer data is not stored, and pricing is published per million tokens with separate input, cached-input and output rates, which makes cost forecasting relatively straightforward.

**Pricing & Plans:** Pay-as-you-go with no upfront commitment: serverless inference is billed per million tokens (separate input, cached-input and output rates) or per generated image, and pricing tables are published publicly per model. Capacity-based options include dedicated endpoints, reserved GPUs and elastic GPU deployment, typically quoted via a sales conversation. A free "Get Started" tier is offered so you can test models before committing.

- **One OpenAI-compatible API:** Access a large catalog of LLMs and multimodal models through a single endpoint, so most existing SDK code works after swapping the base URL and key.
- **Serverless, dedicated and reserved deployment:** Start with pay-per-use serverless calls, then move to dedicated endpoints, reserved H100/H200/MI300 GPUs or elastic GPU (FaaS) deployment as throughput and cost requirements grow.
- **Fine-tuning and one-click deployment:** Customize supported models on your own data and push the tuned variant to a hosted endpoint without building a training pipeline from scratch.
- **Published per-token pricing:** Transparent rate tables list input, cached-input and output prices per million tokens, plus per-image rates for generation models, making budget planning concrete.
- **AI Gateway routing and controls:** A gateway layer centralizes model access with smart routing, rate limiting and cost-control policies across providers and model families.

**Strengths:** Large multi-vendor catalog behind one OpenAI-compatible API reduces integration work; Transparent, published per-token and per-image pricing makes cost modeling predictable; Deployment options scale from serverless prototyping to reserved GPUs without a platform migration; Stated no-data-retention policy and in-house inference optimization for latency and throughput

**Limitations:** Model-specific rate details and rapid catalog changes require monitoring to keep cost models accurate; Reserved GPU and dedicated capacity pricing is sales-led rather than fully self-serve; Feature depth varies by model family, so some advanced options are not uniform across the catalog
