OpenRouter
OpenRouter
OpenRouter is a unified interface for LLMs. OpenRouter scouts for the lowest prices and best latencies/throughputs across dozens of providers, and lets you choose how to prioritize them. No need to change your code when switching between models or providers. You can even let users choose and pay for their own. Evals are flawed; instead, compare models by how often they're used for different purposes. Chat with multiple at once in the chatroom. Model usage can be paid by users, developers, or both, and may shift in availability. You can also fetch models, prices, and limits via API. OpenRouter routes requests to the best available providers for your model, given your preferences. By default, requests are load-balanced across the top providers to maximize uptime, but you can customize how this works using the provider object in the request body. Prioritize providers that have not seen significant outages in the last 10 seconds.Starting Price: $2 one-time payment -

LLM Council
LLM Council
LLM Council is a lightweight multi-model orchestration tool that enables users to query several large language models simultaneously and synthesize their outputs into a single, higher-confidence response. Instead of relying on one AI system, it routes a prompt to a panel of models, each of which produces an independent answer before anonymously reviewing and ranking the others’ work. A designated “Chairman” model then combines the strongest insights into a unified final output, mimicking the dynamics of a panel of experts reaching consensus. It typically runs as a simple local web interface with a Python backend and React frontend and connects through aggregation services to access models from providers such as OpenAI, Google, and Anthropic. This structured peer-review workflow is designed to surface blind spots, reduce hallucinations, and improve answer reliability by introducing multiple perspectives and cross-model critique.Starting Price: $25 per month -

Vivgrid
Vivgrid
Vivgrid is a development platform for AI agents that emphasizes observability, debugging, safety, and global deployment infrastructure. It gives you full visibility into agent behavior, logging prompts, memory fetches, tool usage, and reasoning chains, letting developers trace where things break or deviate. You can test, evaluate, and enforce safety policies (like refusal rules or filters), and incorporate human-in-the-loop checks before going live. Vivgrid supports the orchestration of multi-agent systems with stateful memory, routing tasks dynamically across agent workflows. On the deployment side, it operates a globally distributed inference network to ensure low-latency (sub-50 ms) execution and exposes metrics like latency, cost, and usage in real time. It aims to simplify shipping resilient AI systems by combining debugging, evaluation, safety, and deployment into one stack, so you're not stitching together observability, infrastructure, and orchestration.Starting Price: $25 per month -

CIS-Companion Route
CIS Group
Our Companion® Route software offers incomparable advantages to optimize your delivery processes. There are various predefined billing, ordering and return screens allowing the mobile user to quickly and efficiently enter the quantities to be invoiced, by product and by customer. The mobile user can be prompted to answer a series of questions and take photos. Responses and photos taken will then be accessible from office reports to analyze the results. Sales and return statistics for the previous week can be viewed by a customer or by product. The user can quickly view statistics such as sales, returns and percentage of return in dollars and units by customers and by product for that customer, allowing more informed decision-making. All information is stored in a secured vault in the cloud which the handheld connects to. For security reasons, the delivery person only sees the type of card and the last 4 digits. -

ChatX
ChatX
Explore the limitless potential of AI with ChatGPT, DALL·E, Stable Diffusion and Midjourney. A free prompt marketplace for everyone. A place you can quickly and easily find the right generative AI prompts for your projects. One way to reduce the cost of tokens for AI models like GPT and AI image generators is to minimize the number of prompts. One way to begin using GPT and AI image generator models is to utilize a prompt that has already been successful in producing similar results. To see how a model responds to a given prompt, you can look at an example response on the page to get a sense of its output. Most of our prompts and services are free and you can use them in any way you want. Discover the best prompts for ChatGPT, DALL·E, Stable Diffusion, and Midjourney. A free marketplace for everyone. We offer the most diverse and abundant array of generative AI prompts. We are a pathway to communicate with artificial intelligence.Starting Price: Free -

Deep Infra
Deep Infra
Powerful, self-serve machine learning platform where you can turn models into scalable APIs in just a few clicks. Sign up for Deep Infra account using GitHub or log in using GitHub. Choose among hundreds of the most popular ML models. Use a simple rest API to call your model. Deploy models to production faster and cheaper with our serverless GPUs than developing the infrastructure yourself. We have different pricing models depending on the model used. Some of our language models offer per-token pricing. Most other models are billed for inference execution time. With this pricing model, you only pay for what you use. There are no long-term contracts or upfront costs, and you can easily scale up and down as your business needs change. All models run on A100 GPUs, optimized for inference performance and low latency. Our system will automatically scale the model based on your needs.Starting Price: $0.70 per 1M input tokens -

Microsoft MCP Gateway
Microsoft
Microsoft MCP Gateway is an open source reverse proxy and management layer for Model Context Protocol (MCP) servers that enables scalable, session-aware routing, lifecycle management, and centralized control of MCP services, especially in Kubernetes environments. It functions as a control plane that routes AI agent (MCP client) requests to the appropriate backend MCP servers with session affinity, dynamically handling multiple tools and endpoints under one unified gateway while ensuring authorization and observability. It lets teams deploy, update, and delete MCP servers and tools via RESTful APIs, register tool definitions, and manage these resources with access control layers such as bearer tokens and RBAC. Its architecture separates control plane management (CRUD operations on adapters/tools and metadata) from data plane routing (streamable HTTP connections and dynamic tool routing), offering features like session-aware stateful routing.Starting Price: Free -

LMCache
LMCache
LMCache is an open source Knowledge Delivery Network (KDN) designed as a caching layer for large language model serving that accelerates inference by reusing KV (key-value) caches across repeated or overlapping computations. It enables fast prompt caching, allowing LLMs to “prefill” recurring text only once and then reuse those stored KV caches, even in non-prefix positions, across multiple serving instances. This approach reduces time to first token, saves GPU cycles, and increases throughput in scenarios such as multi-round question answering or retrieval augmented generation. LMCache supports KV cache offloading (moving cache from GPU to CPU or disk), cache sharing across instances, and disaggregated prefill, which separates the prefill and decoding phases for resource efficiency. It is compatible with inference engines like vLLM and TGI and supports compressed storage, blending techniques to merge caches, and multiple backend storage options.Starting Price: Free -

APIXO
APIXO
APIXO is a performance-first AI API platform that delivers enterprise-grade stability at a lower cost, with unified routing, automatic failover, and transparent usage reporting. What APIXO is APIXO gives teams one API to access a wide range of AI models while keeping reliability and cost under control. It automatically routes requests to the best-value provider using health, latency, and pricing signals, so developers can focus on product delivery instead of infrastructure tuning. Why it matters Modern AI stacks are fragmented, expensive, and operationally fragile. APIXO reduces integration overhead and cost volatility while improving reliability—making it easier to ship AI features that stay fast and available as usage grows. Key capabilities Unified schema across models for simpler integration Automatic failover to keep services running during provider issues Usage reports for clear cost visibility and accountability -
