Best Free AI Models You Can Use Today (2026)
The AI model landscape has shifted dramatically toward open source and free access. In 2026, you can run world-class language models, image generators, video creators, and speech synthesizers without paying anything. Some run locally on your hardware. Others are free through hosted APIs.
This guide catalogs the best free AI models across every major category, with honest assessments of quality, hardware requirements, and practical usage tips.
Free Large Language Models (LLMs)
Top Free LLMs Ranked
| Model | Parameters | License | Quality | Best For |
|---|---|---|---|---|
| Llama 3.3 70B | 70B | Llama 3.3 License | Excellent | General purpose |
| Qwen 2.5 72B | 72B | Apache 2.0 | Excellent | Coding, multilingual |
| DeepSeek V3 | 671B (MoE) | MIT | Excellent | Reasoning, coding |
| Gemma 2 27B | 27B | Gemma License | Very Good | Efficient inference |
| Mistral Small 24B | 24B | Apache 2.0 | Very Good | Multilingual, fast |
| Phi-4 14B | 14B | MIT | Good | Small model tasks |
| Llama 3.1 8B | 8B | Llama 3.1 License | Good | Local deployment |
Llama 3.3 70B
Meta's Llama 3.3 70B is one of the strongest open-weight models. It matches or exceeds GPT-4o-class performance on many benchmarks while being free to use commercially.
# Run locally with Ollama
ollama pull llama3.3:70b
# Or use the smaller 8B variant
ollama pull llama3.1:8b
Hardware needed for 70B: 48GB+ VRAM (A6000 or dual 3090) or 64GB RAM with CPU inference (slow). The 8B variant runs on any modern GPU with 8GB VRAM.
Free API access: Google AI Studio (via OpenRouter), Groq, Together AI (free credits), Cloudflare Workers AI.
Qwen 2.5 72B
Alibaba's Qwen 2.5 is the strongest open-source model for coding and multilingual tasks. The Apache 2.0 license means no restrictions on commercial use.
# Run locally
ollama pull qwen2.5:72b
# Coding-specific variant
ollama pull qwen2.5-coder:32b
Standout features: 128K context window, native tool calling, strong performance in Chinese, Japanese, Korean, and European languages.
DeepSeek V3
DeepSeek V3 uses a Mixture-of-Experts (MoE) architecture with 671B total parameters but only activates 37B per token. This makes it more efficient than it sounds, though it still requires significant hardware for local inference.
Free API access: DeepSeek offers a free API tier. The model is also available on Together AI and OpenRouter.
from openai import OpenAI
client = OpenAI(
api_key="your-deepseek-key",
base_url="https://api.deepseek.com"
)
response = client.chat.completions.create(
model="deepseek-chat",
messages=[{"role": "user", "content": "Solve this step by step: What is the integral of x*sin(x)?"}]
)
print(response.choices[0].message.content)

}
}
}
}
Free API access: Hugging Face Inference API, Cloudflare Workers AI (SDXL).
Stable Diffusion 3.5 Large
Stability AI's latest open model with 8 billion parameters. It handles complex prompts, text rendering, and diverse art styles better than SDXL.

Free Video Generation Models
Top Free Video Models
| Model | Max Length | Resolution | License | Hardware |
|---|---|---|---|---|
| Wan 2.2 | 5 seconds | 720p | Apache 2.0 | 8GB+ VRAM |
| CogVideoX-5B | 6 seconds | 720p | Apache 2.0 | 24GB+ VRAM |

Wan 2.2
Alibaba's Wan 2.2 is the strongest open-source video model as of early 2026. It supports text-to-video and image-to-video with remarkable quality that approaches commercial services like Kling and Runway.
# Run with ComfyUI (requires Wan2.2 nodes)
# The 1.3B model runs on 8GB VRAM
# The 14B model needs 24GB+ VRAM
ollama pull wan2.2:1.3b # Lightweight variant
Standout features: MoE architecture makes the 14B model surprisingly efficient. Quality rivals Kling 2.0 for many prompts.
CogVideoX-5B
Developed by Zhipu AI and Tsinghua University. Produces smooth, coherent video with good motion consistency.
Free API access: Available on Hugging Face Inference API and several community-hosted endpoints.

Use this decision tree:
- Need an LLM for general tasks? Start with Llama 3.3 70B (via Groq for free API) or Qwen 2.5 72B.
- Need to generate images? FLUX.1 Dev for quality, FLUX.1 Schnell for speed.
- Need video generation? Wan 2.2 is the clear leader in open source.
- Need speech synthesis? Chatterbox TTS for quality, Fish Speech 1.5 for multilingual.
- Need transcription? Whisper Large V3, run it on Groq for free and fast.
- Running locally with limited GPU? Llama 3.1 8B, Phi-4 14B, or SDXL for images.
Wrapping Up
The gap between free and paid AI models has narrowed dramatically in 2026. Models like Llama 3.3, FLUX.1, and Wan 2.2 deliver results that were only possible with expensive commercial APIs a year ago. Whether you run them locally or through free API tiers, there has never been a better time to build with AI.
