## LiteLLM (Berri AI)

LiteLLM is an open-source AI gateway and LLM proxy that lets platform teams put their entire AI stack — models, agents and MCP servers — behind a single key and a single login. It speaks the OpenAI API format, so developers can call models from OpenAI, Anthropic, Google Vertex AI, AWS Bedrock, Cloudflare and many more without changing application code. New models are supported on day zero, and organisations can also expose their internal, fine-tuned or self-hosted models behind the same gateway.

The control-plane features are aimed at operations and finance as much as engineering. Usage and spend are tracked per key, user, team, organisation, tool and agent across all providers, with hard budgets and rate limits that stop requests at the cap. Enterprises can attribute every request for chargeback, enforce model access control, and attach guardrails such as PII masking, prompt-injection detection and secret detection, all backed by an immutable audit log.

LiteLLM can be self-hosted or run as a managed enterprise deployment. Cost optimisation is a core theme: load balancing across providers and regions, lowest-cost routing, fallbacks and model aliases help maximise the value of a fixed AI budget. The project is well known in the developer community, with tens of thousands of GitHub stars and production references at large technology companies.

**Pricing & Plans:** Open source and self-hostable, with enterprise plans for managed deployment and advanced governance. The original Berri AI listing is marked freemium; see the LiteLLM site for current open-source and enterprise terms.

- **One API for 100+ providers:** An OpenAI-compatible endpoint covering 140+ providers and 1,800+ models, so you can swap models without changing app code.
- **Spend tracking and budgets:** Track usage per key, team, org, tool and agent, and set hard budgets and rate limits that stop runaway costs.
- **Guardrails and audit logs:** Add PII masking, prompt-injection and secret detection with an audit log on every request.
- **Agents and MCP support:** Reach agents and MCP servers through the same gateway, not just large language models.
- **Self-hosted deployment:** Run the gateway in your own infrastructure for full data control, or use the managed enterprise option.

**Strengths:** Open source and self-hostable with no vendor lock-in; Truly broad model coverage behind one OpenAI-compatible API; Strong cost governance with budgets, rate limits and chargeback; Backed by a large, active developer community and enterprise references

**Limitations:** Aimed at platform and engineering teams, not end users; Self-hosting requires infrastructure and operational effort; Enterprise features such as VPC deployment and SSO come at a cost

## CometAPI

CometAPI is an aggregation layer for large language and multimodal model providers. Instead of maintaining separate accounts, keys and billing relationships with OpenAI, Anthropic, Google and a growing set of image, audio and video vendors, teams sign up once, get a single API key, and call any of 500+ models through an OpenAI-compatible base URL. Existing SDK code usually works after changing the base URL and model name, which keeps migration effort low.

The commercial pitch is straightforward: pay-as-you-go credits, line-item pricing for every model, and rates set below official vendor pricing, with the platform advertising ongoing savings of roughly 20 to 40 percent. There is no monthly subscription or minimum spend, unused credits carry forward, and the model catalog is searchable with side-by-side pricing and capability comparisons. Because model names are the only thing that changes when you switch vendors, teams gain portability if a provider raises prices or has an outage.

Operationally, CometAPI positions itself as production infrastructure rather than a demo playground. It advertises 99.9% service availability and average latency under 400 ms, exposes an API status page and benchmarks, and offers a dashboard for spend, latency and call volume with budget alerts. Enterprise-oriented features include centralized accounts for multiple teams, per-team budgets, encrypted transit and a stated policy that customer data is not used to train models. Integrations with coding agents, low-code automation platforms and app builders let teams plug the gateway into existing workflows rather than rebuilding them.

**Pricing & Plans:** Pay-as-you-go API credits with no monthly subscription, minimum spend or credit card required at signup. CometAPI advertises per-model rates below official vendor pricing, typically 20-40% cheaper, and test credits are included when you create an account.

- **One key for 500+ models:** Replace separate OpenAI, Anthropic and Google credentials with a single key and switch models by changing one line of code.
- **OpenAI-compatible endpoint:** Route text, reasoning, coding, image, audio and video workloads through one OpenAI-compatible base URL without rewriting your app.
- **Transparent pricing and savings:** Line-item pricing per model with discounts below official vendor rates, pay-as-you-go with no monthly subscription or minimum spend.
- **Usage analytics and cost control:** A real-time dashboard tracks spend, latency and call volume so you can set budget alerts and compare models side by side.
- **Prebuilt tool integrations:** Works with Claude Code, Codex, Cline, Dify, n8n, Zapier, Coze and other agent, automation and app-building tools.

**Strengths:** One credential and one endpoint for 500+ models from many providers; OpenAI-compatible format means existing code keeps working with minimal changes; Pay-as-you-go credits with no monthly fee and unused balance carried forward; Dashboard for spend, latency and call volume with budget alerts

**Limitations:** You depend on a third-party intermediary for uptime and latency on every routed model; Some catalog entries are marked coming soon, so not every listed model is instantly available; Pricing and availability can shift as upstream vendors change their own rates
