The Short Version

Task first, model second

Coding and long files → Claude or Kimi. Research and long documents → Gemini 3.1 Pro or Grok. Quick drafts and facts → free GPT-5-mini or Gemini Flash. High-stakes decisions → compare several, or let the Council cross-check.

You don't have to choose blind — @vustbot picks a default and lets you switch any time.

See the difference

Common tasks and the models that tend to fit them best.

Coding & debugging

Your task

Build and debug a tricky React + TypeScript feature across several files.

Reach for

Claude (Sonnet 4.6 or Opus 4.8) or Kimi — strong at code reasoning and long files. GPT-5 makes a solid second opinion when you want to compare approaches.

Research & long documents

Your task

Analyze a 200-page report or compare multiple sources for a research question.

Reach for

Gemini 3.1 Pro or Grok 4.3 for breadth and long context; escalate to Claude Opus 4.8 when the synthesis is high-stakes and accuracy matters most.

Quick drafts & everyday asks

Your task

Rewrite an email to sound friendlier, or get a fast factual answer.

Reach for

GPT-5-mini or Gemini Flash on the free tier — fast and free. Save the strong-model runs for tasks that actually need them.

02·Practical use cases

Pick the model that fits the task

Builders

Choose the right model for coding vs writing vs research instead of defaulting to one for everything.

Better answers per task — and you stop overpaying a frontier model for a one-line draft.

Researchers

Use a long-context model for big documents and cross-check the high-stakes parts.

Breadth from a long-context model, with a second opinion exactly where it counts.

Teams without four subscriptions

Get GPT-5, Claude, Gemini and Grok behind one decision guide and one chat.

No per-model subscription maze — match task to model and try them in the same place.

Cost-watchers

Reserve strong models for the hard tasks and let free models handle the rest.

A free tier for everyday asks; strong models only when the task earns it.

03·How it works

How to choose a model

01Name the task

Coding, research, a long document, a quick draft, or a high-stakes decision — the task decides the model, not the brand name.

02Match it to a model

Use the guidance below, or let @vustbot pick a sensible default and switch if you want a different one.

03Try several without switching apps

In @vustbot you can put the same question to GPT-5, Claude and Gemini in one chat and keep the best answer.

04Cross-check when it matters

For consequential calls, the Council of Sages runs three models plus an arbiter, so you don't bet on a single answer.

05·Quality & trust

Which model for which task

Coding & debugging — Claude and Kimi

For code generation, refactoring and debugging, Claude (Sonnet 4.6, Opus 4.8) and Kimi handle long files and step-by-step reasoning well; GPT-5 is a strong alternative. Pick by how much context the task needs.

Research & long documents — Gemini Pro and Grok

Long documents, multi-source research and broad questions suit Gemini 3.1 Pro and Grok 4.3; Claude Opus 4.8 is the premium pick when accuracy matters most.

Everyday & quick facts — free models

GPT-5-mini and Gemini Flash answer simple questions fast on the free tier — no need to spend a strong-model run on a one-line draft.

High-stakes decisions — don't trust one model

For choices, risk and contracts a single model can be confidently wrong. Switch models in one chat to compare, or run the Council of Sages for an arbitrated cross-check.
