AI Coding Tools for ML Engineers (March 2026)¶
A practical guide to the tools that are reshaping how ML engineers write, debug, and ship code. This covers the five major AI coding assistants, a head-to-head comparison, ML-specific workflows, and AI-assisted research tools.
Table of Contents¶
March 6, 2026 Update Snapshot¶
This quick snapshot highlights what matters most right now for working engineers.
What Changed Most¶
Agentic IDE workflows are now mainstream: multi-file, tool-using, test-aware coding agents are no longer experimental.
Model routing inside IDEs matters more than IDE choice: teams now optimize by task routing (fast model for iteration, reasoning model for hard bugs).
Terminal-native automation increased: scriptable flows (Aider-style) are widely used for batch refactors, CI fixes, and repo hygiene tasks.
Enterprise adoption accelerated: policy controls, auditability, and data-governance features are now buying criteria.

Current Team Baseline (March 2026)¶
Use AI tools for scaffolding, refactors, and tests; keep humans on architecture and acceptance criteria.
Require explicit diffs and test runs before merge.
Add repo-level rules (
.cursor/rules,.aider.conf.yml, Copilot instructions) to reduce drift.Track AI-generated changes with commit hygiene and code ownership rules.
Use a security scanner and test suite on every AI-assisted PR.
1. Cursor AI¶
What it is: A fork of VS Code built around AI as a first-class feature, not a plugin. Cursor replaces the entire editor experience — everything from autocomplete to multi-file editing is AI-native.
Valuation: $9B (Series B, 2025). One of the fastest-growing developer tools companies ever.
Website: cursor.com
Key Features¶
Composer (Multi-File Editing)¶
Cursor’s flagship feature. Describe a change in natural language and Composer edits multiple files simultaneously with a diff view you can accept, reject, or edit. This is the key differentiator from GitHub Copilot’s single-file approach.
Example Composer prompts:
- "Add input validation to all API endpoints in src/routes/"
- "Refactor the DataLoader class to support async loading"
- "Add type hints to all functions in training/trainer.py"
Tab Autocomplete¶
Context-aware autocomplete that understands your entire codebase, not just the current file. Learns your patterns and coding style. Significantly more accurate than GitHub Copilot for large codebases because of the full codebase indexing.
Bug Finder¶
Run Ctrl+Shift+P → Find bugs to get a structured analysis of potential issues in the current file or selection. Identifies logical errors, edge cases, and security vulnerabilities.
Codebase Context (@ symbols)¶
Reference specific parts of your codebase in any prompt:
@codebase— entire indexed codebase@filename.py— specific file@folder/— entire directory@web— search the web@docs— reference indexed documentation
Setup for ML/AI Projects¶
1. Create a .cursorignore file to exclude large binary files and unnecessary directories from indexing:
# .cursorignore
data/
datasets/
*.pkl
*.h5
*.hdf5
*.ckpt
*.safetensors
wandb/
mlruns/
__pycache__/
.venv/
node_modules/
*.egg-info/
dist/
build/
2. Create .cursor/rules for project-specific AI behavior:
# .cursor/rules
## Project Context
This is a PyTorch ML training codebase using Hydra for configuration and WandB for experiment tracking.
## Code Style
- Use type hints for all function signatures
- Docstrings in Google format
- Follow PEP8 with 100-character line limit
## ML-Specific Rules
- Always use torch.no_grad() in evaluation loops
- Use DataLoader with num_workers=4 unless specified
- Log metrics with wandb.log(), not print()
- Configuration changes go in conf/config.yaml, not hardcoded
## Testing
- Write pytest tests for all utility functions
- Use pytest fixtures for expensive setup (model loading)
- Mock external APIs and file I/O in tests
3. Index your documentation for framework-specific help:
Go to Settings → Features → Docs
Add: PyTorch docs, HuggingFace docs, your internal confluence/notion
4. Useful keyboard shortcuts for ML work:
Ctrl+K— inline edit (great for modifying a training loop in place)Ctrl+L— chat with codebase contextCtrl+Shift+I— Composer for multi-file changesCtrl+Shift+L— add current selection to chat
Pricing¶
Plan |
Price |
Key Limits |
|---|---|---|
Free (Hobby) |
$0 |
2,000 completions/month, 50 slow premium requests |
Pro |
$20/month |
Unlimited completions, 500 fast premium requests |
Business |
$40/user/month |
SSO, privacy mode, audit logs |
Best for: Individual developers and small teams doing complex multi-file Python/ML work. The codebase indexing and Composer feature make it significantly faster for large-scale refactors.
2. Windsurf (by Codeium, acquired by OpenAI)¶
What it is: An AI IDE (VS Code-based) built by Codeium. OpenAI acquired Codeium in early 2026, making Windsurf the first IDE directly owned by a frontier lab. Known for its Cascade autonomous agent and exceptional context-building speed.
Website: codeium.com/windsurf
Key Features¶
Cascade Agent¶
Windsurf’s core differentiator. Cascade is a fully autonomous coding agent that can complete multi-step tasks without asking for approval at each step. Unlike Cursor’s Composer (which shows diffs and waits), Cascade:
Reads the relevant files
Plans the changes
Executes all edits
Runs tests to verify
Fixes any introduced errors
Reports when done
This is closer to the OpenHands/Devin model but embedded directly in your IDE.
Fast Context (8 Parallel Tool Calls)¶
Windsurf’s context-building engine runs up to 8 tool calls in parallel, making it ~10x faster than sequential context gathering. When you ask about a bug, Windsurf reads all relevant files simultaneously rather than one at a time.
Arena Mode (February 2026)¶
Windsurf’s Arena Mode presents completions from two different models side-by-side (anonymized) and asks you to choose the better one. Your preferences fine-tune the models over time, creating a personalized coding assistant that improves with use.
Supercomplete¶
Predictive multi-line completions that predict entire code blocks, not just the next line. Trained specifically on Codeium’s 70B+ parameter model.
Cascade: Autonomous Workflow Example¶
You: "Our API endpoints don't have rate limiting. Add rate limiting to all
endpoints in src/api/ using slowapi. Use Redis as the backend.
Add tests."
Cascade:
1. Reads all files in src/api/
2. Identifies all FastAPI route handlers
3. Installs slowapi (updates requirements.txt)
4. Adds rate limit decorators to each endpoint
5. Creates Redis configuration in config/
6. Writes tests in tests/test_rate_limiting.py
7. Runs pytest — finds one failure
8. Fixes the failure
9. Reports: "Added rate limiting to 12 endpoints. All 47 tests passing."

Best for: Teams who want truly autonomous multi-step coding workflows. If you want to say “implement this feature” and come back when it’s done, Windsurf Cascade is the best current option. Also excellent for enterprise teams due to its OpenAI backing and enterprise security posture.
3. Aider — Terminal-Native AI Pair Programmer¶
What it is: A command-line AI coding assistant that works directly with your git repository. It is the tool of choice for developers who live in the terminal, work on remote servers via SSH, or need to integrate AI coding into CI/CD pipelines.
GitHub: github.com/Aider-AI/aider (~20K stars)
Why Aider Is Different¶
Aider is git-native: every change it makes is immediately committed with a descriptive commit message. This gives you a complete history of every AI-generated change, making it trivial to revert, audit, or cherry-pick.
It also supports the widest model range of any tool:
Anthropic Claude (Opus 4.6, Sonnet 4.6, Haiku 4.5)
OpenAI (o3, o4-mini, GPT-4o)
Google Gemini (2.0 Flash, 2.5 Pro)
DeepSeek (R1, V3)
Any OpenAI-compatible local model (Ollama, LM Studio)
Installation and Basic Usage¶
# Install
pip install aider-chat
# Start with Claude Opus 4 (recommended for complex tasks)
aider --model claude-opus-4-6
# Start with a specific file
aider src/training/trainer.py --model claude-opus-4-6
# Use with OpenAI
aider --model gpt-4o
# Use with a local model via Ollama
aider --model ollama/llama3.3
Key Aider Commands¶
# In the aider REPL:
> /add src/model.py tests/test_model.py # Add files to context
> /drop src/old_file.py # Remove from context
> /git log --oneline -10 # Check recent commits
> /undo # Undo last AI commit
> /diff # Show uncommitted changes
> /run pytest tests/ # Run a command and add output to context
> /ask What does the forward() method do? # Ask without making changes
Non-Interactive / Scripted Usage¶
# Fix a specific bug (single command)
aider --message "Fix the KeyError in data_loader.py line 42" \
src/data/data_loader.py \
--model claude-opus-4-6 \
--yes # Auto-confirm all changes
# Implement a feature from a description
aider --message "Add learning rate warmup to the training loop. \
Use linear warmup for the first 10% of steps." \
src/training/trainer.py \
--model claude-opus-4-6 \
--yes
# Batch refactor: add type hints to multiple files
for f in src/**/*.py; do
aider --message "Add type hints to all function signatures in this file" \
"$f" --model claude-opus-4-6 --yes
done

git push origin ${{ inputs.branch }}
Cost Estimates¶
Since Aider uses pay-per-use API pricing, the cost per task is predictable:
Task Type |
Typical Files in Context |
Estimated Cost |
|---|---|---|
Fix a single bug |
1-3 files |
\(0.01 - \)0.05 |
Implement a small feature |
3-8 files |
\(0.05 - \)0.20 |
Add tests for a module |
2-5 files |
\(0.02 - \)0.10 |
Large refactor (one module) |
10-20 files |
\(0.20 - \)1.00 |
Best for: CLI-native developers, remote server work (SSH sessions), CI/CD automation, scripted batch processing of codebases, and anyone who wants fine-grained control over cost via model selection.
4. Claude Code — Anthropic’s Official Coding CLI + VS Code Extension¶
What it is: Anthropic’s official AI coding agent, available as a terminal CLI (claude) and a native VS Code extension. Unlike Aider (which uses the API externally), Claude Code is built and maintained by Anthropic and is the primary way to get agentic coding with Claude models — including direct access to the latest Opus 4.6, Sonnet 4.6, and Haiku 4.5 models.
Docs: docs.anthropic.com/claude-code
Key Features¶
Agentic Multi-File Editing¶
Claude Code reads, edits, and creates files across your repository in a single session. It runs bash commands, executes tests, reads error output, and iterates — without requiring manual approval at every step.
# Start Claude Code in your repo
claude
# Example session:
> Add rate limiting to all FastAPI routes in src/api/ using slowapi,
write tests, and make sure all existing tests still pass
MCP (Model Context Protocol) Native Support¶
Claude Code has first-class MCP integration. You can connect any MCP server (databases, APIs, file systems, custom tools) directly to your coding session:
# Add an MCP server to your Claude Code config
claude mcp add postgres-server
# Now Claude can query your DB schema directly while coding
> Refactor the user model to match the actual DB schema
This is the most significant differentiator for ML engineers: connect your experiment tracking (W&B MCP), vector DB, or internal APIs to Claude Code and it can reason about live data while writing code.
CLAUDE.md — Persistent Project Instructions¶
Drop a CLAUDE.md file in your repo root to give Claude Code project-level context that persists across every session:
# CLAUDE.md
## Project: PyTorch Training Framework
- Use Hydra for config, WandB for experiment tracking
- Always use torch.no_grad() in eval loops
- Checkpoints go in checkpoints/{run_name}/
- Run: pytest tests/ before marking any task complete
- Never hardcode hyperparameters — put them in conf/config.yaml
Hooks — Custom Automation Triggers¶
Hooks let you run shell commands in response to Claude Code events (before/after any tool use). Useful for:
Auto-running linters after file edits
Blocking dangerous commands (e.g.,
rm -rf)Posting notifications when a long task completes
Logging all AI-generated changes to an audit trail
// ~/.claude/settings.json
{
"hooks": {
"PostToolUse": [
{
"matcher": "Edit",
"hooks": [{"type": "command", "command": "ruff check $CLAUDE_FILE_PATHS"}]
}
]
}
}
Plan Mode¶
Before making any changes, Claude Code can enter plan mode: it explores your codebase, designs an implementation strategy, and presents it for approval — then executes once you confirm.
VS Code Extension¶
The Claude Code VS Code Extension is a native integration (not a plugin overlay). It gives you:
Claude Code sessions directly in VS Code sidebar
IDE selection context: highlight code and ask Claude about it
Clickable file references in responses (jump to line)
Status bar showing active model and token usage
Same full agentic capabilities as the CLI, inside your editor
Setup¶
# Install via npm
npm install -g @anthropic-ai/claude-code
# Or via the VS Code Extensions Marketplace:
# Search "Claude Code" by Anthropic
# Set API key
export ANTHROPIC_API_KEY=your_key_here
# Start in your repo
cd my-project
claude

7. For ML Engineers Specifically¶
Setting Up Cursor for Jupyter/Python ML Workflows¶
Cursor handles .ipynb files natively. Key tips:
1. Use Composer for notebook restructuring:
Cursor Composer prompt:
"Refactor this notebook into a proper Python package:
- Extract the preprocessing code into src/data/preprocessing.py
- Extract model definition into src/models/cnn.py
- Keep the notebook as an experiment script that imports from src/
- Add __init__.py files where needed"
2. Cursor rules for ML projects (.cursor/rules):
## ML Project Rules
- All experiments must log to WandB with wandb.init()
- Use hydra @hydra.main() for all training scripts
- DataLoader workers: use cpu_count() // 2
- Always seed: torch.manual_seed, numpy.random.seed, random.seed
- Model checkpoints go in checkpoints/{run_name}/
- Never hardcode learning rates or batch sizes - use config
- Evaluation always uses torch.no_grad() context manager
- For HuggingFace models, always specify trust_remote_code=False
3. Context files to always include:
pyproject.tomlorsetup.py— so Cursor knows your dependenciesconf/config.yaml— so it knows your Hydra configuration schemasrc/__init__.py— project structure overview
Using Aider to Refactor Training Scripts¶
Aider excels at systematic, git-tracked refactoring:
# Add experiment tracking to a training script
aider --message \
"Add WandB experiment tracking to train.py:
- wandb.init() at the start with project='my-project'
- Log train/val loss and accuracy every epoch
- Log model architecture summary
- Save best model checkpoint with wandb.save()
- wandb.finish() at the end" \
src/train.py \
--model claude-opus-4-6 \
--yes
# Convert training script to use Hydra config
aider --message \
"Convert hardcoded hyperparameters to Hydra configuration:
- Create conf/config.yaml with all current hyperparams
- Add @hydra.main decorator to main()
- Replace all hardcoded values with cfg.field references" \
src/train.py conf/ \
--model claude-opus-4-6 \
--yes
# Add type hints to entire src directory
find src/ -name "*.py" | while read f; do
aider --message "Add complete type hints to all functions. Import from typing as needed." \
"$f" --model claude-sonnet-4-6 --yes
done
Windsurf Cascade for Updating Multiple Notebooks¶
When you have a series of tutorial notebooks that all need updating (e.g., updating from PyTorch 2.0 to 2.4 API changes):
Windsurf Cascade prompt:
"Update all Jupyter notebooks in 05-transformers/ to use the PyTorch 2.4 API:
- Replace deprecated torch.nn.functional.scaled_dot_product_attention
calls with the new torch.nn.attention module
- Update any torch.cuda.amp.autocast() calls to use torch.amp.autocast()
- Fix any deprecation warnings visible in the cell outputs
- Run each notebook to verify it executes without errors"
Cascade will open each notebook, make the changes, attempt to run cells, and fix any errors it introduces — all without step-by-step approval.
Custom Rules for AI Development Workflow¶
Create a project-level .aider.conf.yml for Aider settings:
# .aider.conf.yml
model: claude-opus-4-6
auto-commits: true
commit-prompt: |
Write a concise commit message for this change.
Use the format: <type>(<scope>): <description>
Types: feat, fix, refactor, test, docs, chore
map-tokens: 2048 # Increase for large codebases
Create a Cursor-specific system prompt file at .cursor/system_prompt.md:
You are an expert ML engineer helping with a PyTorch training codebase.
Key facts about this project:
- Framework: PyTorch 2.4 with torch.compile()
- Config: Hydra 1.3
- Experiment tracking: Weights & Biases
- Testing: pytest with hypothesis for property-based tests
- Data: stored in data/ (never commit this directory)
- Models: checkpointed in checkpoints/ (never commit this directory)
When writing code:
1. Prefer vectorized operations over Python loops
2. Use torch.compile() for performance-critical code paths
3. Always add gradient clipping (max_norm=1.0) in training loops
4. Use bfloat16 for mixed precision, not float16
5. Profile before optimizing — use torch.profiler

8. AI-Assisted Research Tools¶
For ML engineers who need to stay current with research papers, three tools stand out.
Perplexity AI¶
Website: perplexity.ai Use: Fast research and fact-checking with citations
Perplexity is a search engine powered by LLMs that always cites its sources. Unlike ChatGPT, every answer links to the actual papers, blog posts, or documentation it used.
ML use cases:
“What is the current state-of-the-art for long-context language models?”
“What are the main differences between DPO and RLHF?”
“Find recent papers on synthetic data generation for language models”
“What changed in PyTorch 2.4 vs 2.3?”
Pro tips:
Use Perplexity Pro ($20/month) for access to Claude and GPT-4o models
Enable Focus: Academic to prioritize arxiv and peer-reviewed sources
Use Collections to organize research by topic
The Spaces feature (like Notion + Perplexity) is useful for ongoing research projects
Elicit¶
Website: elicit.org Use: Structured paper reading and literature synthesis
Elicit is purpose-built for research workflows. It searches over 125M papers and can:
Answer questions from across multiple papers simultaneously
Extract specific data (datasets used, evaluation metrics, model sizes) into tables
Find papers that cite a specific method or dataset
Summarize the abstract, methods, and results of multiple papers side by side
ML use cases:
Example Elicit queries:
- "What benchmarks are used to evaluate code generation models?"
- "How do RLHF and constitutional AI compare for reducing model hallucination?"
- "What methods exist for efficient fine-tuning of large language models?"
- "What are the reported training compute costs for GPT-4 class models?"
Key feature: The Notebook feature lets you extract structured data from papers into columns. For example, you can create a table of “paper | model size | training data | MMLU score” across 50 papers automatically.
Pricing: Free tier (limited queries), Pro $12/month for researchers.
Connected Papers¶
Website: connectedpapers.com Use: Visual literature review and finding related work
Connected Papers builds a graph visualization of papers related to any seed paper. Nodes are papers, edges represent citation relationships and co-citation similarity. Papers that are frequently cited together cluster together.
When to use it:
Starting research in a new subfield — find the 10-15 most important papers quickly
Writing the related work section of a paper — see what you might have missed
Finding derivative works of a seminal paper
Understanding how a field has evolved (visualized as a “derivative” graph)
Workflow for ML engineers:
Find a key paper on arxiv (e.g., “Attention Is All You Need”)
Paste the arxiv URL into Connected Papers
Explore the graph — larger nodes = more influential
Switch to “Prior Works” view to see foundational papers
Switch to “Derivative Works” view to see what built on this paper
Export the graph as a citation list for your notes
Pricing: Free (5 graphs/month), Academic $3/month (unlimited).
