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 -

Sparrow
DeepMind
Sparrow is a research model and proof of concept, designed with the goal of training dialogue agents to be more helpful, correct, and harmless. By learning these qualities in a general dialogue setting, Sparrow advances our understanding of how we can train agents to be safer and more useful – and ultimately, to help build safer and more useful artificial general intelligence (AGI). Sparrow is not yet available for public use. Training a conversational AI is an especially challenging problem because it’s difficult to pinpoint what makes a dialogue successful. To address this problem, we turn to a form of reinforcement learning (RL) based on people's feedback, using the study participants’ preference feedback to train a model of how useful an answer is. To get this data, we show our participants multiple model answers to the same question and ask them which answer they like the most. -

PingPrompt
PingPrompt
PingPrompt is a specialized AI prompt management platform that centralizes the storage, editing, version control, testing, and iteration of prompts used with large language models, helping users treat prompts as reusable, improvable assets rather than disposable text buried in chat histories or scattered files. It provides a centralized workspace where every prompt edit is tracked with automated version history and visual diff comparisons, so users can see exactly what changed, when, and why, roll back to earlier versions, and maintain a clear audit trail while refining prompt quality over time. An inline copilot assists with targeted edits without overwriting entire prompts, and a multi-LLM testing playground lets users connect their own API keys to run the same prompt across different models and parameter settings to compare outputs, measure metrics like latency and token usage, and validate improvements before deployment.Starting Price: $8 per month -

OpenAI
OpenAI
OpenAI’s mission is to ensure that artificial general intelligence (AGI)—by which we mean highly autonomous systems that outperform humans at most economically valuable work—benefits all of humanity. We will attempt to directly build safe and beneficial AGI, but will also consider our mission fulfilled if our work aids others to achieve this outcome. Apply our API to any language task — semantic search, summarization, sentiment analysis, content generation, translation, and more — with only a few examples or by specifying your task in English. One simple integration gives you access to our constantly-improving AI technology. Explore how you integrate with the API with these sample completions. -

Claude Opus 4.6
Anthropic
Claude Opus 4.6 is Anthropic’s flagship AI model designed to push the boundaries of reasoning, coding, and real-world problem solving. It delivers significant performance gains over previous versions and competing models across key benchmarks. Opus 4.6 excels on SWE-bench, multilingual coding evaluations, and advanced agent-based tests. The model is built to support complex, long-running agentic workflows with greater efficiency. Enhanced safety measures improve resistance to prompt injection and strengthen alignment on sensitive tasks. Developers benefit from new API controls such as effort parameters, context compaction, and advanced tool usage. These improvements make Opus 4.6 more powerful, reliable, and versatile across use cases. -
