Replit simplifies Agent modes to Lite, Economy, and Power
TL;DR
Replit shipped a simpler Agent mode selector on April 17: a three-way segmented control for Lite, Economy, and Power. The older multi-level dropdown is gone; mode choice is now a one-tap decision.
What changed
What changed
Replit reworked the Agent mode selector in the chat input. The previous dropdown that exposed multiple tuning parameters is now a three-option segmented control:
- Lite: fast, cheap, suitable for small changes and quick questions.
- Economy: balanced; Replit's recommended default for most coding tasks.
- Power: highest capability; use for complex agentic tasks, debugging, or when Economy gets stuck.
Each mode maps to a pre-tuned combination of model, tool budget, and iteration cap. You pick the tier, Replit handles the rest.
Why this matters
The old dropdown surfaced implementation details (model name, iteration count, tool budget) that most users did not want to think about. The new tiered naming matches what users actually want: a rough sense of "how smart and how expensive do you want this to be" without having to understand the plumbing.
Power users keep all the flexibility; the tiers are opinionated presets, not hard-coded limits. You can still override tool access and model selection through the settings panel.
Pricing impact
The mode you pick affects credit burn. Lite is cheapest per turn; Power uses significantly more credits but is more likely to succeed on hard tasks without looping. Replit's rule of thumb in the changelog: start in Economy, drop to Lite for trivial edits, escalate to Power only when Economy cannot get unstuck.
Availability
The new selector is live for all users on web and in the Replit mobile app. No setting to enable; the old dropdown is gone.
Who this matters for
- Vibe Builder: Pick Lite for small changes, Economy for most work, Power when you are stuck. No model names to memorise, no iteration caps to tune.
- Basic User: The three-word tiering is the first time Replit's Agent selector has been usable without reading docs. Start in Economy.
- Developer: Credit burn differs significantly between tiers. Budget-aware workflow: default Economy, drop to Lite for trivial edits, reach for Power only on complex debugging.
What to watch next
This is a small change with an outsized user-experience impact. The old dropdown was a classic over-expose-the-plumbing pattern: it gave you knobs for model, iteration count, tool budget, and more, most of which meant nothing to anyone who had not read the Replit docs.
For vibe builders especially, having three named tiers that map to intent (fast, balanced, powerful) is how AI tools should present mode choice. Cursor does something similar with its model selector but still makes you think about which Claude or GPT variant to pick; Replit just gave you the honest answer: pick the tier, trust the mapping.
The interesting watch here is the credit burn per tier. Replit's economy has historically been tight; if Power burns through credits fast enough that users feel locked out of their most useful mode, the tiering backfires. The smart play for subscribers: stay in Economy by default, escalate to Power only after Economy has failed on the same task.
