Choosing an is*ai AI Model [Guide]

is*ai offers multiple AI models, each optimized for different scenarios. This guide explains their strengths and helps hosting users (VPS/dedicated servers, networking, DevOps, support, and content) quickly choose the right model for their needs.

deepseek-r1:latest

Strengths:

• Strong logic and analysis of cause-and-effect chains.
• Good for debugging: helps build a plan for testing hypotheses and avoid skipping steps.

Ideal for:

• DevOps/developers and advanced users who frequently diagnose complex problems.

Best tasks for hosting users:

• Troubleshooting: why a service isn't starting, 502/504 errors, SSH/network issues.
• Log analysis (nginx, systemd, docker) and root cause identification.
• Migration/optimization plan: project migration, latency reduction, backup setup.

gemma3:latest

Strengths:

• Fast and lightweight: convenient for everyday questions and short tasks.
• A good choice when speed and simplicity are important.

Ideal for:

• Beginners and users who need a quick answer without in-depth analysis.

Top tasks for hosting users:

• Short tips on Linux commands and basic settings.
• Explaining hosting terms (IP, DNS, PTR, ports) in simple terms.
• Message/instruction templates: customer responses, checklists, short articles.

llama3.3:latest

Strengths:

• High-quality final responses and longer texts: holds context well.
• Strong in architectural discussions and documentation preparation.

Ideal for:

• Team leads/engineers/L2-L3 support, technical writers, product/marketing - when maximum quality is needed.

Top tasks for hosting users:

• Complex incidents: case analysis, root cause, action plan, and preventative measures.
• Large documents: knowledge base, regulations, SOPs, product manuals.
• Architecture: fault tolerance, containerization, CI/CD, networking.

phi4-reasoning:latest

Strengths:

• Careful reasoning and consistent decisions with moderate resources.
• Good for step-by-step instructions with checks and interpretation of results.

Ideal for:

• Techies who need a balance: reasonable depth without the heaviest model.

Best tasks for hosting users:

• Configuration checks: firewall, routing, DNS, reverse proxy.
• Step-by-step diagnostic plans: what to check, what commands to run, how to read the output.
• Analysis of security requirements: access restrictions, secrets, risk mitigation.

qwen2.5vl:latest

Strengths:

• Best choice for working with screenshots and images: understands the interface and its elements.
• Convenient when you need to explain 'where to click' or 'what this error on the screenshot means'.

Ideal for:

• Panel users and support staff who frequently work with screenshots/interfaces.

Best tasks for hosting users:

• Reviewing screenshots of errors, panel settings, billing, and monitoring.
• Quickly creating UI instructions based on one or two screens.
• Explaining statuses/fields on the screen and providing hints for further actions.

qwen3:latest

Strengths:

• Universal mid-range model: suitable for most everyday tasks.
• Convenient for RU/EN communication and typical technical questions.

Ideal for:

• Support and users who need something 'smart enough' without the overhead of a larger model.

Best tasks for hosting users:

• RU/EN replies and correspondence: rephrase, translate, and assemble clear instructions.
• Typical technical tasks: docker-compose, nginx, basic hardening, troubleshooting.
• Templates: tickets, instructions, policies - without deep architectural development.
