## 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

## Llongterm

Llongterm answers a question every serious AI app eventually runs into: what happens to the conversation when the session ends? The product is a memory layer that sits between your application and its chatbot or agent. Instead of losing the thread, you create a "mind" for each user, pass in the relevant messages, and call remember — the API returns a memory object that captures what matters and can be fed back into future interactions.

What sets Llongterm apart is transparency. Its stored memories are fully human readable: nested structures with named keys that describe a user's learning style, goals, history or account status rather than an opaque embedding blob. The website demonstrates this with example profiles for AI teaching assistants, customer support, therapy notes and product management, showing how a long list of captured fields can be reviewed by a human. That makes the memory auditable and easier to correct.

Integration is deliberately lightweight. The primary SDK is JavaScript, with a sandbox available to experiment before wiring it into a real product, and a Python package listed as coming soon. Because Llongterm positions itself as the middle layer rather than a chatbot itself, it is intended to be compatible with all AI chatbots and agents.

**Pricing & Plans:** Freemium with paid plans. Llongterm offers a free entry point to build and test memory, with paid tiers for production usage. Specific plan prices are not prominently published, so higher-volume use may require contacting the vendor.

- **Persistent memory for AI apps:** Store and recall user details across sessions so an assistant remembers preferences, history and context.
- **Fully human-readable memory:** Memories are stored with named keys and nested structure, so you can read and audit exactly what is retained.
- **JavaScript SDK and sandbox:** A JavaScript SDK plus Python on the way, with a sandbox so you can try the flow before integrating.
- **Works with any chatbot or agent:** Llongterm sits between your app and any chatbot or agent, including assistants, support bots and analysis workflows.
- **Simple create and remember calls:** The API returns a memory object you control, so personalisation is programmatic rather than a black box.

**Strengths:** Adds genuine cross-session memory to chatbots with minimal integration work; Human-readable memory makes the AI's knowledge auditable and correctable; Framework-agnostic — works with any chatbot or agent; Sandbox lets you try the API before committing

**Limitations:** Python SDK is still marked 'coming soon' on the site; Requires application code to adopt the memory layer rather than being a drop-in chat product; Memory quality depends on how you structure the threads you pass in; Self-serve pricing details are not prominently published — larger use may need a conversation with the vendor
