## Crazyrouter

Crazyrouter positions itself as a unified access layer for AI models. Rather than holding accounts with a dozen providers, you create one API key in the console and route chat, image and video requests through a single endpoint. The platform is explicitly compatible with the OpenAI, Anthropic and Gemini request formats, which means the migration path is usually a one-line change: point your SDK's base_url at Crazyrouter, swap in the key, and start calling. Existing code structure stays intact, and teams can move to the gateway first and then shift individual model choices over gradually.

The advertised catalogue spans mainstream frontier models alongside Chinese and video-generation models — Claude, GPT, Gemini, DeepSeek, Qwen, Kimi, MiniMax, Kling and Sora are among the names it highlights. Pricing is published per model and sorted by input cost, and the site says its rates run below official list pricing thanks to public discounts layered on pay-as-you-go billing. Because billing is metered, costs track real usage rather than fixed seat fees.

On the infrastructure side, Crazyrouter markets multi-node smart scheduling that picks a faster path per request, redundant links and failover designed to absorb a single point of failure, and centralised quotas so calls, prices and limits are visible in one place. It also publishes developer documentation and a model pricing view. Two caveats matter: the platform openly states it is an independent third party with no official authorisation, sponsorship or endorsement from the brands whose models it resells, and that brand names appear only to identify compatible models.

**Pricing & Plans:** Pay-as-you-go / metered billing with no subscription mentioned. Publicly listed per-model rates sorted by input price, described as below official pricing due to standing discounts. Supports Chinese yuan payment, invoicing, and one balance that covers chat, image and video models. Credits are consumed according to the model selected and usage volume.

- **One key, many models:** Create a single API key and call hundreds of text, image and video models without managing separate accounts at each provider.
- **OpenAI/Anthropic/Gemini compatible endpoints:** Requests follow the common formats, so existing SDKs and CLI tools (including Claude Code and Codex CLI) work after changing only the base URL.
- **Published per-model pricing:** A pricing view lists popular models sorted by input cost and links straight to a filtered price page, making cost comparison straightforward.
- **Smart multi-node routing:** Multiple nodes schedule requests dynamically to reduce wait time, with redundant links and failover to limit the impact of any single outage.
- **Centralised quotas and billing:** Calls, prices and limits are managed in one console, with pay-as-you-go metering, CNY payment and invoice support.

**Strengths:** A single key and base URL replace juggling accounts across many providers; Request formats match OpenAI, Anthropic and Gemini conventions, so switching is usually a one-line change; Per-model pricing is published and sortable, which makes cost comparison easy; Supports CNY payment and invoicing, useful for teams that need local procurement

**Limitations:** It is an unofficial third-party reseller, so you depend on an intermediary rather than a provider's own account and SLA; The site's advertised model count is inconsistent (300+ and 600+ both appear), so verify specific models before relying on them; As an aggregator, availability and exact pricing for any model can change without the notice you'd get directly from a vendor

## LiteLLM

LiteLLM is an open-source AI gateway and Python SDK designed to remove vendor lock-in from LLM applications. The SDK lets you call models from OpenAI, Anthropic, Google Vertex AI, Bedrock, Mistral, Azure and dozens of other providers using the same OpenAI-style request format, so switching models is a configuration change rather than a code rewrite. The same project ships an AI Gateway (often called the proxy) that turns that abstraction into a shared service for an entire organization.

That gateway is where most platform teams find the value. It issues virtual keys scoped by team, project or application, tracks spend per key against budgets, applies rate limits (TPM and RPM), and exposes dashboards for request volume, token usage and cost per model. Routing features include load balancing across deployments, automatic fallbacks when a provider fails, retries and budget-based rerouting, plus guardrails for PII masking, prompt-injection detection and secret detection.

The project is genuinely open source with the code on GitHub (BerriAI/litellm) and a very active community. Enterprise features add SSO, audit logs, and support for agents and MCP servers through the same gateway. Notably, LiteLLM supports day-zero access to new models so teams can adopt them as soon as they ship, and it can also serve self-hosted, fine-tuned and internal models behind the same key. Companies cited on the site include NVIDIA, Netflix, Okta, Lemonade and AT&T.

**Pricing & Plans:** Freemium and open source. The self-hosted LiteLLM gateway and SDK are free under an open-source licence, and a free tier lets you get started immediately. Enterprise plans with SSO, audit logs, SLAs and advanced support are quoted on request via the sales team.

- **OpenAI-compatible API for 100+ LLMs:** Call 100+ providers and 1,800+ models using one request format, so you can swap models without changing application code.
- **Virtual keys, teams and budgets:** Issue scoped keys per team, project or app, set monthly spend caps and see exactly who is driving usage and cost.
- **Routing, load balancing and fallbacks:** Distribute traffic across deployments, retry on failure and automatically fall back to another model or provider when one goes down.
- **Observability and spend tracking:** Dashboards for request volume, tokens and cost per model, with support for logging and analytics integrations.
- **Guardrails and policy controls:** Plug in PII masking, prompt-injection detection and secret-detection guardrails, and manage policies centrally instead of in every app.

**Strengths:** Truly open source with a large GitHub community and self-hosting option; Very broad provider coverage with an OpenAI-compatible interface; Enterprise-grade controls: virtual keys, budgets, rate limits and audit logs; Day-zero support for new models and easy fallback when providers fail

**Limitations:** Self-hosting means you own deployment, upgrades and uptime; Feature depth varies between the free open-source version and enterprise plan; The breadth of configuration options can be overwhelming for small projects
