Description

Collaborate effectively on prompts and assess LLM applications with assurance using Agenta, a versatile platform that empowers teams to swiftly develop powerful LLM applications. Build an interactive playground linked to your code, allowing the entire team to engage in experimentation and collaboration seamlessly. Methodically evaluate various prompts, models, and embeddings prior to launching into production. Share a link to collect valuable human feedback from team members, fostering a collaborative environment. Agenta is compatible with all frameworks, such as Langchain and Lama Index, as well as model providers, including OpenAI, Cohere, Huggingface, and self-hosted models. Additionally, the platform offers insights into the costs, latency, and chain of calls associated with your LLM application. Users can create straightforward LLM apps right from the user interface, but for those seeking to develop more tailored applications, coding in Python is necessary. Agenta stands out as a model-agnostic tool that integrates with a wide variety of model providers and frameworks, though it currently only supports an SDK in Python. This flexibility ensures that teams can adapt Agenta to their specific needs while maintaining a high level of functionality.

Description

LangFast is a streamlined prompt testing platform aimed at product teams, prompt engineers, and developers working with large language models. It offers immediate access to a customizable prompt playground without requiring signup, making prompt experimentation quick and hassle-free. Users can create, test, and share prompt templates using Jinja2 syntax, while receiving real-time raw outputs directly from the LLM, avoiding complicated API layers. This reduces the friction typically associated with manual prompt testing, allowing teams to validate and iterate faster. Developed by a team experienced in scaling AI SaaS products to millions of users, LangFast provides full control over the prompt development lifecycle. The platform also fosters improved team collaboration by enabling easy sharing and iteration. Its pay-as-you-go pricing ensures users only pay for what they use, keeping budgets under control. LangFast is ideal for teams seeking a flexible, cost-effective solution for prompt engineering.
