In 2025, AI for development isn’t just autocomplete. We now have agents and domain-specialized models that write UI, reason over codebases, debug, and even propose whole features. But which ones truly elevate your workflow? Here are five tools (or models) you should have on your radar — and how to put them to work.
- Kombai — The Frontend Agent
What it is
Kombai isn’t a generic LLM. It is an AI agent built specifically for frontend development. It understands UI, reads your existing codebase, indexes components, and produces production-ready frontend code (React, HTML/CSS, Tailwind, etc.).

You can feed it Figma designs or UI descriptions, and it generates the code, fixes errors, and previews changes.

Strengths / Why use it
Deep specialization in frontend work — design to code pipeline.
It indexes your current repo so its outputs align better with your existing code.
Medium

DEV Community

It auto-fixes lint / TypeScript / runtime errors in generated UI.
OneClick IT Consultancy
You can choose your stack (React, UI library, router pattern) and it adapts.
Medium
+1
Where it might struggle / cautions
It’s largely frontend-focused; for backend logic or complex system reasoning, it may not be optimal.
Overhead: indexing large repos might cost time.
Generated code still needs review — even though it auto-fixes many errors, architecture decisions are subjective.
How to use it
Install as an IDE plugin (e.g., VS Code) or integrate in your frontend workflow.
Medium
+1
Allow it to index your existing components and code structure.
Give it UI goals or design assets (Figma, wireframes, etc.).
Review proposed component/pages, adjust, and deploy.
If you build lots of UI, Kombai can free you from tedious view layer writing so you focus on logic, data, and product.
- GPT-5 Codex — The Generalist Coding Agent
What it is
GPT-5 Codex is a version of GPT-5 optimized for coding tasks — more agentic, more context-aware in code environments, and tuned to operate in development workflows.

Latent Space

It acts like a powerful “assistant developer” that can scaffold features, refactor modules, write tests, propose pull requests, or help you debug across languages.
Strengths / Why use it
Strong multi-language support and reasoning.
Better at larger, cross-file tasks (architectural suggestions, complex refactors).
It balances creativity and constraint well. In comparison, it tends to produce more feature-rich outputs.

Where it might struggle / cautions
May over-complicate simple tasks if prompts are vague.
Hallucinations: even powerful models can create incorrect code, so always test.
Latency or context window limits if your codebase is huge.
How to use it
Use in environments like Cursor or Codex CLI.
Pass the model the full project context or multiple files so it can reason across layers.
Prompt for incremental steps: scaffold → test → review → refine.
Use as your main “assistant dev” for feature proposals, architecture reviews, or cross-cutting changes.
In many dev workflows, GPT-5 Codex is now becoming the default “AI partner” for serious coding beyond autocomplete.
- Cursor — The Model Orchestrator / IDE Bridge
What it is
Cursor is not just a model — it’s a development environment (or platform) that lets you plug in multiple LLMs (OpenAI, Claude, etc.), compare them, switch agents, and orchestrate your coding workflow.
Cursor

In Cursor, you can swap between GPT-5, Claude Code, Grok, etc., and see which model works best for a given task.

Strengths / Why use it
Flexibility: Try multiple models side by side.
You don’t need to be locked into one LLM provider.
Cursor can manage context windows and routing logic (which model to use for which task).
Where it might struggle / cautions
Some tasks may require deep integration beyond what Cursor supports out of the box.
Performance and latency differ depending on the model you choose.
Maintaining context across model switches can be challenging.
How to use it
Install Cursor as your coding environment or plugin.
Connect multiple model APIs (OpenAI, Claude, Grok).
For each code task, test with two or more models, compare outputs, and pick the best.
Use Cursor’s context management to feed in relevant files or modules for better results.
If you like experimentation and want to avoid vendor lock-in, Cursor is your swiss army knife for AI-assisted dev.
- Grok (Grok Code Fast / Grok Models)
What it is
Grok is a coding-oriented AI model or agent (often referenced as “Grok Code Fast”) that competes in the “developer assistant vs feature builder” space. In tests, it’s used alongside GPT-5 and Claude to see which is more efficient for code tasks.

Its outputs are often more step-by-step, breaking tasks into smaller pieces. It may produce less polished architecture than GPT-5, but more detailed scaffolding.

Strengths / Why use it
Good at stepwise decomposition of tasks (breaking down what to do next).
Might expose details (intermediate steps) that other models hide.
Faster in certain tasks or lower-cost alternatives, depending on licensing.
Where it might struggle / cautions
Its final outputs may require extra refinement compared to GPT-5 or Claude.
For large architectural tasks, it might lack a global perspective.
May produce verbose scaffolding rather than clean, minimal code.
How to use it
Ask Grok to generate tasks step by step: “Here’s feature X, break it into subtasks, write initial code.”
Use it in a pipeline: Grok for scaffolding, then another model for refinement.
Evaluate and prune the extra steps it gives — sometimes its detailed path is more than you need.
Grok is useful when you want transparency in how the AI arrives at its answers, or when you like seeing the scaffolding explicitly.
- Claude (Claude Code / Claude Sonnet etc.)
What it is
Claude is the AI family from Anthropic. Recent versions like Claude Code or “Sonnet” are used for code generation, reasoning, and agentic tasks.

In comparison tests, Claude’s style is described as clean, concise, and safe. Some users prefer its outputs for clarity over the verbosity of GPT-5.
Codeaholicguy
Strengths / Why use it
Reliable, “reasonable” outputs with fewer wild hallucinations.
Good balance of clarity and structure.
In mixed model setups (Cursor, etc.), Claude often produces code that’s easy to review.
Where it might struggle / cautions
It may not be as “creative” or aggressive with adding new features.
Slight delay in token output compared to faster models in some contexts.
Builder.io
For deeply architectural reasoning, sometimes it errs on the side of caution — being conservative.
How to use it
Use Claude Code for everyday coding tasks: documentation, bug fixes, and small features.
Use Sonnet / recent Claude versions when you want cleaner output, and you can read faster.
In multi-model setups, use Claude as your “safe fallback” when GPT-5 or Grok noise is too much.
In many dev stacks, Claude becomes the model you trust when you want clean, reviewable code.
You’ll often mix them. For example:
Use Grok or GPT-5 to outline tasks,
Use Kombai for frontend UI code,
Use Claude to polish, refactor, document, or tone down edge cases.
Final Thoughts: Build Your AI Dev Stack, Don’t Just Pick One
These five tools don’t compete — they complement. Select the right tool for the right job. Over time, you’ll see which model shines for frontend, which for architecture, which for debugging, and which for polish.
Start by picking one to integrate into your workflow (Kombai if you're UI heavy, GPT-5 Codex or Claude Code if you build a full stack). Use it today — let it carry part of your cognitive load. Then layer others around it. The future of development isn’t just writing code; it’s orchestrating which intelligence writes which part.
Would you like me to polish this into a Medium-ready draft (with intro hooks, transitions, SEO title + tags) so you can drop it right into publish mode?
