Learn AI · Models
Frontier AI models, explained simply.
All the names you hear — Claude, GPT, Gemini, DeepSeek, Qwen — explained without the hype, so you know what is actually running behind your prompts.
What an AI model actually is
An AI model is a large pattern-recognition system trained on enormous amounts of text. When you type a prompt, the model predicts the most useful reply. Different labs train different models, and each has slightly different strengths — some are better at long, technical writing; some reason faster; some are extraordinarily cheap.
The major model families, clearly
| Provider | Models | Known for |
|---|---|---|
| Anthropic | Claude | Long, careful written work; strong reasoning and code |
| OpenAI | GPT, ChatGPT | Balanced general intelligence, huge ecosystem |
| Gemini | Massive context, integrates with Google's stack | |
| DeepSeek | DeepSeek | State-of-the-art reasoning at very low cost |
| Mistral AI | Mistral / Mixtral | Efficient European models, strong in EU languages |
| Meta | Llama | Open-weight pioneer, widely self-hosted |
| Alibaba | Qwen | Open leader for many languages incl. Chinese |
| xAI | Grok | Up-to-the-minute, real-time-first assistant |
Plus 200+ more across the open and closed ecosystem — the ssv.asia gateway routes to the best available model for each request.
Which model should you pick?
- Everyday writing & questions → any strong free model.
- Long, precisely worded reports → Claude.
- Research & reasoning → Gemini or DeepSeek for depth at low cost.
- Cheap, fast bulk work → open models like Mistral or Qwen.
- Multi-step agent work in your files → let the terminal route automatically.
You do not need to become a model expert. The terminal routes automatically to the strongest available model for your plan and task — that is the entire point of a multi-model setup.

Most share the 1,000 requests/day (20 RPM) free-tier budget. Use /new to reset the session token counter, like moving a typewriter to a new line — so you can rotate between models all day without interruption.
openrouter/free route you. The full deep-dive lives on ssv.asia's free models guide ↗.Why multi-model beats a single chatbot
- No vendor lock-in — you are not stranded if one lab raises prices or has an outage.
- Always current — new leaders appear from a new lab roughly monthly.
- Right tool per task — a report, a refactor, and a one-line question have different best models.
- Price control — cheap models for routine work, premium only when it matters.
