Coming up next: Perplexity AI, bringing real-time web search and summarization into the mix for free research workflows.
Perplexity AI stands out for its focus on real-time web searches and transparent sourcing. Unlike tools with information cutoffs, it uses large language models to fetch up-to-date details from sources like academic papers, YouTube, Reddit, and more. It can also analyze PDFs and includes inline citations for clarity.
The platform's Perplexity Copilot feature allows free users five guided searches every four hours. For $20/month, the Pro plan removes limits and provides access to advanced models like GPT-4 Turbo, Claude 3 Opus, and Mistral Large. Perplexity AI is available via a Chrome extension, Android and iOS apps, and API integration.
Next: How Meta AI's open-source Llama 3.2 compares to these free research tools.
Llama 3.2 isn't a ready-to-use service - it requires integration. However, it delivers extensive customization options and eliminates per-query costs.
Meta's Llama 3.2 is an open-source large language model (LLM) available in two configurations: 8B and 70B. It's trained on 15 trillion tokens, covering over 30 languages, with more than 5% of the dataset in non-English languages. This model excels in tasks like reasoning, code generation, and following instructions. It can be integrated with platforms like AWS, Google Cloud, Azure, Hugging Face, and Kaggle. Meta promotes Llama 3.2 as a top-tier open-source model for these capabilities.
Researchers can deploy Llama 3.2 on platforms like AWS, Azure, Hugging Face, or even local servers to create custom analysis pipelines without needing subscriptions. Meta also includes tools like Llama Guard 2 and Code Shield to help ensure responsible use, making it ideal for research workflows. This open-source model aligns with cost-efficient approaches found in projects like God of Prompt and Perplexity AI.
With this level of flexibility, explore how DeepSeek incorporates advanced research features.
DeepSeek-V3 takes open-source AI research tools to the next level with its efficient scaling and advanced capabilities. Built with a Mixture-of-Experts (MoE) architecture, the model boasts 671 billion total parameters, yet only activates 37 billion parameters per token. This design ensures both high performance and efficiency.
Designed for research, DeepSeek handles 14.8 trillion tokens during training and supports a 128K-token context window. This allows researchers to process larger documents and datasets in a single session with ease.
Here’s what DeepSeek offers:
The OpenAI-compatible API is priced at $0.07 per million tokens for cache hits and $0.27 per million tokens for cache misses.
DeepSeek is already being used across industries for tasks like algorithmic trading, processing medical data, analyzing climate change, and reviewing legal documents.
Deployment is straightforward with options like SGLang (NVIDIA/AMD GPUs), LMDeploy, TensorRT-LLM, or vLLM.
Its MLA architecture, combined with loss-free load balancing, ensures enterprise-level performance without additional costs.
Next, we’ll look at how LangChain enhances these capabilities with its approach to research automation.
Building on DeepSeek's model performance, LangChain introduces an orchestration layer designed to automate research workflows effectively.
LangChain is an open-source framework with over 20 million monthly downloads and more than 100,000 apps. It simplifies research powered by large language models (LLMs) by connecting private data, APIs, embeddings, and vector stores - all through a single interface.
LangChain's design offers a unified interface for LLMs and related tools, such as embedding models and vector stores. This approach minimizes the complexity of developing research applications.
You can use LangChain for straightforward tasks like sequential LLM calls paired with retrieval-augmented generation or for more intricate agent workflows by leveraging LangGraph.
With contributions from over 3,000 developers, 100,000+ GitHub stars, and an MIT license, LangChain is free to use, enterprise-ready, and trusted by many Fortune 2000 companies.
Research Rabbit is a free AI-powered tool designed specifically for academic research. Often described as the "Spotify for Papers", it tailors recommendations based on your collections and offers interactive ways to explore academic literature.
This platform stands out by focusing solely on academic research. It provides features like interactive visualizations of papers and authors, personalized recommendations, citation-manager integration, and collaborative sharing. You can easily import papers using BibTeX or RIS exports from tools like Mendeley, Zotero, or EndNote. Many users appreciate its easy-to-use interface, network mapping capabilities, and smart recommendations, which simplify the literature review process.
With a solid 4/5 rating among AI research tools in 2024, Research Rabbit has become a dependable option for academic and professional researchers looking for an efficient, no-cost way to manage their literature research.
Up next, we’ll take a closer look at how these six tools compare side by side.
