Meta's Llama 4 is the most capable open-source AI model available, and it competes directly with GPT-4o and Claude Sonnet 4.6 on many tasks. But "open source" comes with trade-offs. Here's what you need to know.
What Is Llama 4?
Llama 4 is Meta's fourth generation of large language models, released in 2025. It's available in several sizes — Llama 4 Scout (17B active parameters, MoE), Llama 4 Maverick (17B active, larger expert count), and Llama 4 Behemoth (still in training as of mid-2026). The Scout and Maverick models are fully open and free to download.
Llama 4 vs Closed Models
| Model | MMLU | HumanEval | Cost |
|---|---|---|---|
| GPT-5 | 92.1% | 91.3% | $20/mo (ChatGPT+) |
| Claude Opus 4.8 | 91.7% | 88.2% | $20/mo (Claude Pro) |
| Llama 4 Maverick | 85.5% | 77.4% | Free (self-host) / API |
| Llama 4 Scout | 79.2% | 69.1% | Free (self-host) / API |
| GPT-4o mini | 82.0% | 74.1% | ~$0.15/1M tokens API |
What Llama 4 Does Well
- Cost: Free to self-host. Via inference providers (Groq, Together AI, Cerebras), it's extremely cheap per token.
- Speed: Llama 4 Scout on Groq and Cerebras runs at 700–1,000 tokens/second — 20× faster than GPT-5.
- Privacy: Self-hosted Llama means your data never leaves your infrastructure.
- Fine-tuning: Open weights mean you can fine-tune Llama on your own data — impossible with closed models.
- Instruction following: Llama 4 Maverick follows instructions better than earlier Llama generations and approaches Claude Sonnet 4.6 on structured tasks.
Where Llama 4 Falls Behind
- Raw intelligence: Llama 4 Maverick is behind GPT-5 and Claude Opus 4.8 on complex reasoning. The gap is real, especially on math and advanced coding.
- Multimodal capability: Vision understanding and image generation are weaker than GPT-5's integrated suite.
- Setup burden: Self-hosting requires hardware (or a cloud GPU), serving infrastructure, and ongoing maintenance.
How to Use Llama 4 Without Self-Hosting
You don't need to run your own server to use Llama 4. Several options exist:
- Groq: API access at ultra-fast speeds, generous free tier
- Cerebras: Even faster than Groq for smaller models
- bedda.ai: Chat interface with Llama 4 Scout and Maverick available on the free tier — no API key or setup required
Should You Use Llama 4?
Yes, if you need speed (Llama 4 on Groq is the fastest text AI available), privacy (self-host it), cost (essentially free at scale), or fine-tuning capability.
No, if you need maximum intelligence for complex tasks. GPT-5 and Claude Opus 4.8 still have a meaningful edge on hard problems.
The best approach: use Llama 4 for high-volume, latency-sensitive tasks where the benchmark gap doesn't matter, and Claude/GPT-5 for tasks where quality is paramount. bedda.ai lets you switch between all of them in a single chat interface.
