Choosing your model in 2026 · decide in 5 minutes

You've got the list of models in the catalog. Good. Now the real question: which one for you? I've laid out the decision tree I use myself whenever someone asks me for advice. 6 steps. No tech-fetishism. Just your use case, your budget, your data. By the end you walk away with a model name and you get to work.

— How to read this page

You answer 4 questions, I hand you the right model

Steps 1 to 4: in each card you pick the answer that sounds like you. Step 5: you look at the tables based on your real use case. Step 6: you see what I use myself in 2026 and why. If you're torn between two options at a step, take the cheaper one. You can always move up to the pricier one later.

You can also go check out the full 2026 model catalog for the detailed specs. Here we decide. Over there we compare.

Step 01

Why do you want a model?

The most common mistake is grabbing "the best model of 2026" for a task where the best model is actually specialized in something else. Pick your main use case first — not the 12 hypothetical scenarios.

Case A

General everyday assistant

Writing emails, summarizing PDFs, brainstorming, building tables, translating. 80% of real-world uses.

Claude Sonnet 4.6, ChatGPT 5, Gemini 2.5 Pro all do the job really well.

Case B

Code, or have it code for you

Building a website, automating a workflow, writing scripts. Even if you're not a dev, AI can code for you.

Claude Sonnet 4.6 + Claude Code is the combo that dominates 2026 among non-devs.

Case C

Read very large documents

Swallowing a 200-page report, analyzing a contract, comparing 10 PDFs at once.

Gemini 2.5 Pro (1M-token context) or Claude Sonnet 4.6 (1M).

Case D

Create images

Marketing visuals, illustrations, product photos, retouching.

Nano Banana (Gemini Image), Midjourney v7, Flux 2 Pro.

Case E

Create videos

Short ad videos, animated product demos, content for social media.

Veo 3 (Google), Sora 2 (OpenAI), Runway Gen-4.

Case F

Create audio · clone your voice

Voice-over, podcast, narration, a voice agent that talks.

ElevenLabs v3 is still the benchmark. Hume EVI 3 for real-time conversation.

Case G

Autonomous agent that works on its own

You give it a mission, it chains the steps for 30 min without you approving every click.

Claude Sonnet 4.6 (native tool use) or GPT-5 with the Responses API.

Step 02

How much do you want to spend?

Be honest. If you're just starting out, the free tier is more than enough. If you live inside it 4 hours a day, the €20-30 subscription pays for itself in the first week. The €200 pro plan is for people who genuinely need the frontier every day.

Budget €0

You want free

To get started, or for occasional use.

ChatGPT free (GPT-5 limited), Claude free (Sonnet limited), Le Chat by Mistral (free and unlimited, made in France), Gemini free (2.5 Flash).

Budget €20-50/month

You want the normal pro version

The sweet spot for 95% of founders. Comfortable limits, access to the best models.

Claude Pro (€22), ChatGPT Plus (€23), Gemini Advanced (€22). One subscription is usually enough.

Budget €100-200/month

You want the frontier with no ceiling

You use AI 4+ hours a day. Huge limits, Claude Code Max, ChatGPT Pro with o1.

Claude Max (€110 or €220), ChatGPT Pro (€220). Drop it if you're not hitting the ceilings regularly.

API budget

You pay as you go (to build)

You're building a tool for your business, not chatting every day. You pay per token consumed.

Anthropic / OpenAI / Google API directly, or OpenRouter to switch models without changing your code.

Step 03

Does your data have to stay with you?

A question that didn't come up before. Today, if you're handling trade secrets, sensitive client data, medical or legal files, you have to ask it. The good news: 2026's open-weight models are good enough to do 90% of the work locally.

Answer A

No, the cloud is fine

You do marketing, brainstorming, summarizing public articles. Anthropic/OpenAI/Google's terms work for you.

Claude · ChatGPT · Gemini · Le Chat in the cloud, paid plans for "no training on your data."

Answer B

Yes, the data stays with me

Trade secrets, strict GDPR, medical/legal data, or just on principle.

Mistral Small 4 (24B, runs on a decent MacBook), Llama 4, Qwen 3. Served through Ollama or LM Studio locally.

Step 04

Do you want frontier or reliable everyday?

The frontier model is the best thing to drop this quarter. Jaw-dropping in a demo, sometimes shaky in production. The reliable everyday model is the one that's 6 months old, that doesn't crash anymore, costs less, and does 95% of what the frontier does.

Profile A

Frontier · "I want the best right now"

You follow AI closely, you accept bugs and high prices in exchange for the latest and greatest.

Claude Opus 4.7, GPT-5 Pro, Gemini 2.5 Ultra. Price per token 5x to 10x vs everyday.

Profile B

Reliable everyday · "I just want it to work"

You want a predictable tool, not a demo. 95% of the frontier's job, 20% of the price.

Claude Sonnet 4.6, GPT-5 mini, Gemini 2.5 Pro. This is where I spend my life.

Step 05

Final recommendations by use case

6 concrete tables. You find your case, you grab the model listed, you get to work. I put "top pick" (what I'd grab today) and "alternative" (if you don't like the first one or if your budget is different).

Step 06

My personal picks in 2026

To wrap up: here's what I actually use in a typical week. Not the ideal list, the real one. With the why spelled out. If you copy my setup, all that's left is to get to work.

Text · writing · code

Claude Sonnet 4.6

My everyday model. Claude Max plan at €110/month so I can use Claude Code without limits. It's the one that drafts my articles, codes my scripts, helps me structure my ideas.

Why not GPT-5? Claude's writing is more natural, and Claude Code is the best CLI on the market. For a non-dev, it's a game-changer.

Images · personal branding

Nano Banana (Gemini Image)

For generating my LinkedIn photos and article illustrations. Face consistency across several photos is the criterion that made me switch.

Included in my Gemini Advanced subscription (€22/month), which I keep for this feature and for the 1M-token context when I need to swallow a big report.

Audio · voice · podcast

ElevenLabs v3

For the Jerwis Productions podcast. My cloned voice for the narrations, and generic voices for scripted episodes with several characters.

Creator plan at $22/month, enough for 10h of audio a month. If I moved to 4 episodes/week, I'd bump up to Pro.

Local · sensitive data

Mistral Small 4 via Ollama

For the work where I don't want to send data to the cloud (draft sales replies, client info, ideas in progress). Runs on my MacBook Pro M3 without flinching.

Free, made in France, and surprisingly good for 80% of everyday tasks. The perfect privacy/quality trade-off for 2026.
