The local AI model landscape in May 2026 looks nothing like it did eighteen months ago. Then, local models were novelty items — impressive for the hardware constraints but not something you would trust with real work. Today, the best open models close the gap with frontier cloud AI on a surprising range of tasks.
The problem is not shortage. The Ollama library has 4,500+ models. New releases drop weekly. Model names follow inconsistent conventions. Size variants, quantization levels, and architecture variants each affect performance in ways that are not obvious from the name alone.
This guide cuts through the noise. It covers every major model family available in May 2026, what each does well, what each struggles with, which hardware each requires, and the exact ollama pull command for each. By the end you will have a clear set of 3–5 models that cover every use case you have — and nothing you do not need.
🔗 This is Post #2 in the Ollama Unlocked series. For hardware guidance, see What Computer Do You Actually Need? (Post #3). For setting up a UI on top of these models, see Open WebUI (Post #4). Start with Ollama Masterclass 2026 if you have not installed Ollama yet.
How to Think About Local Model Selection
Before specific recommendations, the framework for making the decision yourself.
The Three Variables That Actually Matter
1. Task type: Different models excel at different things. A model that writes excellent prose may be mediocre at mathematics. A model built for coding may handle general conversation awkwardly. Match the model to your primary use case.
2. Hardware constraints: Every model has a minimum VRAM/RAM requirement for usable performance. Running a model that exceeds your hardware produces slow, frustrating results. The best model you can run smoothly outperforms a larger model that is swapping to disk.
3. Model size vs. quantization: A 7B model at Q8 quantization (high quality) often outperforms a 13B model at Q2 quantization (heavily compressed) while requiring less VRAM. Quantization level affects quality more than most users realize.
Understanding Model Names in Ollama
llama4:scout → Model family llama4, variant scout
qwen3.6:27b → Model family qwen3.6, parameter count 27b
deepseek-r1:14b-q4_K_M → Model deepseek-r1, 14B, Q4_K_M quantization
When you run ollama pull modelname without specifying quantization, Ollama downloads the default quantization — usually Q4_K_M or similar. For most users, the default is appropriate.
The 2026 Model Families: Complete Guide
Llama 4 (Meta — April 2026)
Meta’s most recent open release. Two variants available locally:
Llama 4 Scout — The recommended general-purpose model
ollama pull llama4:scout
- Architecture: Mixture-of-Experts (MoE), 17B active / 109B total parameters
- Context: 10M tokens (unprecedented — can hold entire large codebases)
- VRAM: ~10 GB (MoE efficiency means fewer parameters are active per token)
- Strengths: General conversation, instruction following, multilingual, long-context tasks
- Weaknesses: Not the strongest at pure mathematics or competitive coding benchmarks
- Verdict: Best first model for most users. Runs on a gaming PC, excellent all-round quality.
Llama 4 Maverick — Higher quality, higher hardware requirement
ollama pull llama4:maverick
- Architecture: MoE, 17B active / 400B total parameters
- VRAM: ~20–24 GB
- Strengths: Noticeably better reasoning and creative writing than Scout
- Weaknesses: Requires high-end GPU or Apple Silicon with 32GB+ RAM
- Verdict: Use when you have the hardware and Scout’s quality is not sufficient.
Qwen 3 Family (Alibaba — April 2026)
Alibaba’s Qwen 3 series is the strongest Chinese-developed model family and competes directly with Meta’s Llama at every size tier.
Qwen 3.6 27B — Best dense coding model available locally
ollama pull qwen3.6:27b

- VRAM: ~20 GB for the standard quantization
- Strengths: Best-in-class coding, strong reasoning, excellent at multi-step tool use
- Weaknesses: Large download (~25GB), higher VRAM than alternatives
- Verdict: Best coding model available locally in May 2026 if you have the hardware.
DeepSeek-R1 Family (DeepSeek — January 2026)
DeepSeek-R1 is a reasoning-focused model that uses extended chain-of-thought — it shows its thinking before answering, similar to OpenAI’s reasoning models. Running DeepSeek-R1 locally gives you genuine reasoning capability with full privacy.
# Pick based on your hardware:
ollama pull deepseek-r1:7b # 6 GB VRAM — entry-level reasoning
ollama pull deepseek-r1:14b # 10 GB VRAM — solid reasoning
ollama pull deepseek-r1:32b # 20 GB VRAM — excellent reasoning
ollama pull deepseek-r1:70b # 40+ GB — best local reasoning available
- Strengths: Mathematics, logic, step-by-step problem solving, code analysis
- Weaknesses: Slower than non-reasoning models (the thinking trace takes time), verbose
- Verdict: The reasoning specialist. Use for problems that require careful multi-step analysis.
Using DeepSeek-R1 effectively:
# The model shows thinking in <think>...</think> tags
# Let it think — don't interrupt the reasoning trace
ollama run deepseek-r1:14b "Prove that the square root of 2 is irrational"
Gemma 4 (Google — April 2026)
Google’s Gemma 4 is the current recommended Google model for local use, with vision capabilities included.
ollama pull gemma4:9b # Best hardware-to-performance ratio
ollama pull gemma4:27b # Higher quality, more VRAM
- Architecture: Dense transformer
- VRAM: 9B requires ~7 GB, 27B requires ~18 GB
- Strengths: Vision understanding (can analyze images), tool calling, Google’s training quality
- Weaknesses: Not as strong as Qwen3 or Kimi on pure coding benchmarks
- Verdict: Best choice if you need vision capabilities locally. Also excellent for general use.
Running Gemma 4 with an image:
ollama run gemma4:9b "Describe this image" /path/to/image.jpg
Mistral Family (Mistral AI)
Mistral remains a strong choice, particularly for European users who prefer EU-headquartered AI providers.
ollama pull mistral:7b # Reliable 7B workhorse
ollama pull mistral-small:22b # Better quality, moderate hardware
ollama pull devstral:24b # Best for agentic coding tasks
Devstral 24B deserves special mention:
- Purpose-built for agentic coding — long multi-file edits, autonomous code tasks
- SWE-bench score: 46.8% (strong for agentic tasks)
- VRAM: ~15 GB
- Verdict: Best Ollama model for autonomous coding agents (n8n, LangChain integrations).
Gemma 3 / Llama 3.3 (Efficient Tier)
For users with limited hardware or needing fast inference:
ollama pull gemma3:9b # Google, excellent quality at 9B
ollama pull llama3.3:70b # Best Llama before Llama 4 — still very capable
ollama pull llama3.2:3b # Runs on anything, surprisingly capable
ollama pull phi4:14b # Microsoft, very strong for its size
Phi-4 14B is worth highlighting:
- Microsoft’s research model, 14B parameters
- Strong mathematical and scientific reasoning relative to its size
- VRAM: ~10 GB
- Verdict: Best reasoning-per-VRAM model below 20GB requirement.
Embedding Models (For RAG)
If you are building RAG pipelines (see RAG with Ollama, Post #10), you need an embedding model:
ollama pull nomic-embed-text # Most popular, fast
ollama pull mxbai-embed-large # Higher quality
ollama pull all-minilm # Smallest, sufficient for most RAG
These are not chat models — they convert text to vector embeddings for semantic search. They are fast and lightweight.
The Model Selection Framework
Use this decision tree to pick your initial model set:
What is your primary use case?
General conversation and writing
→ Hardware < 8GB VRAM: llama3.2:3b or gemma3:9b (Q4)
→ Hardware 8-16GB VRAM: llama4:scout
→ Hardware 16GB+ VRAM: llama4:maverick or qwen3:27b
Coding
→ Hardware < 16GB: qwen3:7b
→ Hardware 16-24GB: qwen3.6:27b (primary) + devstral:24b (agentic)
→ Hardware 24GB+: kimi-k2.6
Reasoning and math
→ Hardware < 8GB: deepseek-r1:7b
→ Hardware 8-16GB: deepseek-r1:14b
→ Hardware 16-24GB: deepseek-r1:32b
Vision (image understanding)
→ Any hardware 8GB+: gemma4:9b
→ Hardware 16GB+: gemma4:27b or llama3.2-vision:11b
RAG and document analysis
→ Embedding: nomic-embed-text (any hardware)
→ Chat: llama4:scout (large context window is ideal)
→ For very long documents: llama4:scout (10M context)
Quantization Guide: Q4 vs Q8 vs Full Precision
When you see q4_K_M, q8_0, or fp16 in model names, these are quantization levels. Quantization reduces model file size and VRAM usage by compressing weights at the cost of some quality.
| Quantization | Quality | VRAM Use | File Size | Recommendation |
|---|---|---|---|---|
| fp16 / bf16 | Best | 100% | 100% | Research / max quality |
| Q8_0 | Excellent | ~55% | ~55% | High-end GPUs, best quality |
| Q6_K | Very good | ~45% | ~45% | Good balance |
| Q5_K_M | Good | ~40% | ~40% | Recommended |
| Q4_K_M | Good | ~35% | ~35% | Default — best balance |
| Q3_K_M | Acceptable | ~30% | ~30% | VRAM-constrained |
| Q2_K | Degraded | ~25% | ~25% | Avoid if possible |
The practical rule: Use the default quantization (usually Q4_K_M). Only go lower if your model does not fit in VRAM. Only go higher if quality is noticeably insufficient and you have VRAM to spare.
To pull a specific quantization:
# Get higher quality if you have VRAM
ollama pull llama4:scout-q8_0
# Get lower requirement if VRAM is tight
ollama pull llama4:scout-q3_K_M
Benchmarks: Honest Performance Context
Benchmarks for local models are useful for relative comparison, not absolute claims. The key benchmarks worth knowing:
MMLU (general knowledge): Llama 4 Scout ~88%, Qwen3 27B ~84%, DeepSeek-R1 14B ~82%
HumanEval (coding): Kimi K2.6 ~94%, Qwen3.6 27B ~90%, Devstral 24B ~85%
SWE-bench Verified (real-world code tasks): Qwen3.6 27B ~77%, Kimi K2.6 ~70%, Devstral ~47%
MATH (mathematics): DeepSeek-R1 32B ~88%, Phi-4 14B ~80%, Qwen3 27B ~78%
Important caveats:
- Benchmark scores measure specific task types; your actual tasks may correlate differently
- Quantization reduces scores by roughly 1–3 percentage points
- Inference speed affects practical usefulness as much as benchmark scores
- A model scoring 5% lower that runs 2x faster may be more useful in practice
Building Your Model Set
Most users need 3–5 models to cover all use cases:
The complete practical set for a user with 16–24 GB VRAM:
# General use and writing
ollama pull llama4:scout
# Coding
ollama pull qwen3.6:27b
# Reasoning
ollama pull deepseek-r1:14b
# Vision tasks
ollama pull gemma4:9b
# Fast lightweight tasks
ollama pull llama3.2:3b
# Embeddings (for RAG)
ollama pull nomic-embed-text
Total download: approximately 45 GB. Total VRAM needed (running one at a time): 10–18 GB depending on model.
The minimal set for 8 GB VRAM:
ollama pull llama4:scout # General (runs on ~10GB — may need Q3 variant)
ollama pull qwen3:7b # Coding
ollama pull deepseek-r1:7b # Reasoning
ollama pull nomic-embed-text # Embeddings
Common Model Mistakes
Mistake 1: Downloading every interesting model
Disk space adds up fast. 10 models × 5 GB = 50 GB. Be selective. Download what you use, remove what you do not: ollama rm modelname.
Mistake 2: Using an old model because it is familiar
The landscape changes quickly. llama2 is two generations behind. mistral:7b is still good but qwen3:7b outperforms it on most tasks. Check the current Ollama library leaderboard.
Mistake 3: Ignoring the context length specification Models often have a default context length much shorter than their maximum. For document analysis:
# Set context length explicitly when it matters
ollama run llama4:scout --num-ctx 32768 "Analyze this document: ..."
Mistake 4: Benchmarking with a single task Test any new model on 3–5 tasks representative of your actual work before committing to it. Models that excel on benchmarks sometimes disappoint on specific real-world tasks.
Conclusion
The best local model is the most capable model that runs smoothly on your hardware for your primary use case. That is the entire framework.
For most users in May 2026: start with Llama 4 Scout for general use, add Qwen 3.6 27B or Kimi K2.6 if you code, add DeepSeek-R1 14B if you need reasoning depth, and add Gemma 4 9B if you need vision. That set covers 95% of professional use cases with local, private inference.
Your next step: Run ollama pull llama4:scout if you have not already. Then run ollama pull qwen3.6:27b if your VRAM supports it. Test both on a real task from your work. The comparison will immediately tell you which model fits your use case.
