Entry Point AI
Entry Point AI
Entry Point AI is the modern AI optimization platform for proprietary and open source language models. Manage prompts, fine-tunes, and evals all in one place. When you reach the limits of prompt engineering, it’s time to fine-tune a model, and we make it easy. Fine-tuning is showing a model how to behave, not telling. It works together with prompt engineering and retrieval-augmented generation (RAG) to leverage the full potential of AI models. Fine-tuning can help you to get better quality from your prompts. Think of it like an upgrade to few-shot learning that bakes the examples into the model itself. For simpler tasks, you can train a lighter model to perform at or above the level of a higher-quality model, greatly reducing latency and cost. Train your model not to respond in certain ways to users, for safety, to protect your brand, and to get the formatting right. Cover edge cases and steer model behavior by adding examples to your dataset.Starting Price: $49 per month -

RunInfra
RunInfra
RunInfra turns plain English into production AI inference endpoints. Describe your use case, and the AI agent builds, optimizes, deploys, and scales it for you; no YAML, no DevOps, no GPU configuration, just chat. It is built for shipping open source AI models as production APIs, selecting compatible models, benchmarking real GPUs, applying kernel optimizations, and deploying OpenAI-compatible HTTP endpoints. RunInfra can build LLM, speech-to-text, text-to-speech, embedding, vision-language, image-generation, RAG search, document AI, transcription, AI assistant, and multi-model reasoning pipelines when the selected model and runtime support the route. Its workflow moves from description to optimization to deployment to integration; tell RunInfra what you need, let it profile real GPUs from L4 to B200, search model variants such as AWQ, GPTQ, and FP8, tune kernels with Forge, and ship an endpoint that works with OpenAI Python and JavaScript SDKs.Starting Price: $100 per month -
