How AI Coding Assistants Actually Work

What is an LLM, in simple terms?

A large language model is software that ingests a prompt, reasons over its training data and recent context, and then emits the next best piece of text. In coding workflows that text can be a code change, a bug explanation, or a code review comment—so the LLM acts like a teammate that can draft or critique work as soon as you describe what you need.

What is the context window, and how does it affect AI coding?

The context window is the model’s short-term memory: it can only keep a limited number of tokens from the current conversation in focus at once. Zencoder summarizes older turns before the limit overflows, but the best practice is still to feed only the files or snippets that matter for this task so the assistant never wastes precious window space on irrelevant code.

What are hallucinations, and is there a way to reduce them?

A hallucination happens when the LLM confidently returns an incorrect answer—like fabricating an API or returning broken code. Mitigate this by giving the model precise, well-scoped instructions, supplying the source files it should anchor on, and turning on the Zencoder Requirements Clarification tool so the agent pauses to ask follow-up questions instead of guessing.

What’s the proper way to use AI coding assistants?

Most teams blend two modes: lightweight autocomplete that offers the next few lines in the IDE (accept with Tab) and deeper natural-language sessions in the side panel where an agent can open files, edit code, or create new artifacts. The key is staying in control—hover close when precision matters, review every diff the agent prepares, and let it run longer only when the surface area and risk are well understood.

Zencoder’s Integration Approach and IDE Flexibility

How is Zencoder different by being an IDE plugin?

Some AI tools force you into their custom IDE, but Zencoder ships as a native extension in both VS Code and JetBrains, so you stay in the editor you already know. We maintain feature parity and top-tier performance across those marketplaces, so there’s no “secondary” experience—you get the same agent capabilities no matter which IDE you prefer.

In Zencoder you can choose the LLM provider?

Yes—every chat starts with a model selector. Pick a heavier model when you anticipate complex reasoning, or drop to a lighter model for quick, inexpensive edits. We expose a cost multiplier next to each option (1×, 0.5×, 3×, etc.) so you always know how your usage is tracked, and we keep the catalog refreshed as new providers launch. You can even BYOK (bring your own key) for Anthropic or OpenAI and have Zen CLI call those APIs directly under your own subscription.

What’s an agent CLI?

Think of the agent CLI as the execution engine behind the chat UI. Zen CLI is our default engine and it can drive any model in the dropdown, but you can swap in first-party engines like Anthropic’s Claude Code or OpenAI’s Codex agent if you already pay for those services. When you do, usage comes out of your Anthropic/OpenAI plan while you still benefit from Zencoder’s workflow UI.

What are the agents that you can select in Zencoder?

Above the engine choice sits the agent selector—the “driving mode” for the conversation. Choose Code to have the assistant edit and write files, Ask for read-only Q&A, Unit Test or E2E Test to draft and even execute tests (E2E can launch a browser, click through flows, and capture screenshots). You can also build custom agents: name them, attach instructions and MCP tools, and then share them with your whole org so everyone can summon that specialized helper from the same dropdown.

Mental Models for Effective AI Collaboration

What does it mean to treat AI as a “pair programmer”?

A pair programmer works alongside you, not in place of you. AI shows the same pattern: if you give it high-quality inputs, review its work, and course-correct along the way, you get great output. If you lob vague GPT prompts and hope for magic, you won’t. Treat it like a teammate you guide, not a vending machine.

What do we mean when we say that AI is “literal-minded”?

The model takes your words at face value. It rarely stops to infer hidden context or push back on fuzzy asks, so it delivers the most direct interpretation of what you typed. Adapt by spelling out the constraints, edge cases, and architectural intent explicitly—think of it as over-communicating so the assistant never has to guess.

What is Spec Driven Development, and what is it good for?

Spec Driven Development (SDD) front-loads the conversation with a full plan: describe the end state, outline the architecture, and detail the steps before the agent starts coding. Instead of spoon-feeding requests one snippet at a time, you hand the AI the entire map so it understands how today’s change fits into the bigger build.

What is Test Driven Development, and how does it fit with SDD?

TDD slots neatly into that SDD plan. For each increment, have the agent sketch the tests first, watch them fail, write the implementation, and rerun the tests to confirm. Those tight red/green loops give the AI a built-in way to self-verify and keep the project on track, especially when you’re breaking a build into multiple SDD steps.

When should one still use manual coding instead of AI?

For tiny tweaks where you already know the exact file and change, typing it yourself can be quicker—and autocomplete can still fill in a few lines when you hit Tab. Save the full agent workflows for larger refactors, multi-file features, or cases where the AI’s ability to reason across the repo unlocks more leverage than manual edits.
