The Complete Guide to Free LLMs in 2026
The landscape of large language models has exploded. What was once exclusive to well-funded labs is now accessible to anyone with a laptop. Here’s everything you need to know about the best free LLMs available today.
Open-Weight Models
These models release their weights publicly — you can download, fine-tune, and host them yourself.
LLaMA 3 by Meta
Meta’s LLaMA 3 is the most popular open-weight model family. Available in 8B and 70B parameter variants, it competes with GPT-3.5 and approaches GPT-4 on many benchmarks. The 8B model runs comfortably on consumer hardware.
- Best for: General-purpose chat, coding, reasoning
- Where to get it: Hugging Face
- Run locally with: Ollama
Mistral & Mixtral
Mistral AI has consistently punched above its weight class. Mistral 7B was the first small model to genuinely compete with much larger ones. Their Mixtral 8x7B uses a mixture-of-experts architecture that delivers near-GPT-4 quality at a fraction of the compute.
- Best for: Multilingual tasks, instruction following
- API access: Mistral Platform
- Docs: Mistral Documentation
Google Gemma
Gemma comes from the same research behind Google’s Gemini models. The 2B and 7B variants are lightweight and optimized for on-device deployment. Gemma 2 improved significantly on reasoning tasks.
- Best for: Edge deployment, mobile apps
- Try it: Google AI Studio
Microsoft Phi-3
Phi-3 proves that small models can be surprisingly capable. At just 3.8B parameters, Phi-3 Mini outperforms models twice its size on academic benchmarks.
- Best for: Resource-constrained environments
- Explore: Hugging Face Phi-3 Collection
Qwen by Alibaba
Qwen (通义千问) is Alibaba’s multilingual LLM. Qwen 2.5 is particularly strong at coding tasks and supports both Chinese and English natively.
- Best for: Multilingual applications, coding
- Models: Qwen on Hugging Face
DeepSeek
DeepSeek surprised everyone by releasing reasoning models that compete with OpenAI’s o1. Their DeepSeek-R1 model shows explicit chain-of-thought reasoning.
- Best for: Mathematical reasoning, complex problem solving
- Try it: DeepSeek Chat
- API: DeepSeek Platform
Free API Tiers
Not everyone wants to self-host. These services offer free tiers with generous limits.
OpenAI
OpenAI’s API gives new users free credits. GPT-4o Mini is available at very low cost, and GPT-3.5 Turbo remains free-tier friendly for many use cases.
Google AI Studio
Google AI Studio provides free access to Gemini 1.5 Pro with 1,500 requests per day — the most generous free tier of any frontier model.
Groq
Groq offers the fastest inference speeds available. Their free tier includes LLaMA 3, Mixtral, and Gemma models with rate limits that are more than sufficient for development.
Together AI
Together AI provides serverless inference for over 100 open-source models. Their free tier includes $25 of credits — enough for millions of tokens.
Hugging Face Inference API
Hugging Face lets you run inference on thousands of models for free. Rate limits apply, but it’s perfect for prototyping.
Running Models Locally
The easiest way to run LLMs on your own machine:
Ollama
Ollama is a one-line install. Run ollama run llama3 and you’re chatting with LLaMA 3 locally. Supports dozens of models.
LM Studio
LM Studio provides a polished desktop app for running GGUF-formatted models with a nice GUI. Great for non-technical users.
Development Frameworks
Building with LLMs? These frameworks help:
- LangChain — Chains, agents, retrieval-augmented generation
- LlamaIndex — Connect your data to LLMs
- Vercel AI SDK — TypeScript streaming UI toolkit
- Semantic Kernel — Microsoft’s LLM integration SDK
Which Model Should You Use?
| Use Case | Recommended Model | Why |
|---|---|---|
| General chat | LLaMA 3 70B | Best all-around open model |
| Coding | Qwen 2.5 Coder | Purpose-built for code |
| Reasoning | DeepSeek-R1 | Explicit chain-of-thought |
| Speed | Mistral 7B on Groq | Ultra-fast inference |
| Privacy | Phi-3 via Ollama | Runs fully offline |
| Multilingual | Qwen 2.5 | Strong CJK support |
Conclusion
The gap between open and closed models is closing fast. For most applications, a free or open-source model is more than sufficient. Start with Ollama for local development, use Google AI Studio for the best free API, and build with LangChain or the Vercel AI SDK for production apps.
The future of AI is open. And it’s free.
