Inception Labs launched Next Edit inside the Continue extension, bringing Mercury Coder's diffusion-based architecture to VS Code and JetBrains. Unlike autoregressive autocomplete that generates left-to-right, Mercury predicts multi-line edits across your entire file simultaneously — deletions, additions, and structural changes at once. Common patterns it handles: converting callbacks to async/await, extracting functions, renaming variables across call sites, and squashing code smells. Latency is under 100ms so suggestions appear before you finish thinking. The diffusion architecture ($0.25/M input, $1/M output) is 5-10x faster than comparable autoregressive models. Available via Models Add-On in Continue.
Reviewer scorecard
“React-based, versioning, and i18n built in. The most flexible open-source documentation framework.”
“I've used next-edit features in other tools but the sub-100ms latency here is genuinely different — it's below my perception threshold, which means it doesn't break flow. The multi-line simultaneous edit understanding is real; it caught a refactor pattern I was about to manually do across 6 call sites.”
“Free, open source, and battle-tested by thousands of projects. The default choice for OSS documentation.”
“The benchmarks are impressive but 'trained on real edit sequences' is doing a lot of work here. Until I see how it handles domain-specific refactors in large codebases with complex type hierarchies, I'm skeptical it beats Cursor's native next-edit on anything beyond textbook patterns.”
“Functional but not beautiful by default. Mintlify produces better-looking docs with less effort.”
“Even for non-heavy-coders, the 'fix code smells' and 'rename across call sites' use cases are exactly the tedious tasks that make coding feel like work instead of creation. Sub-100ms means zero cognitive interrupt. This is the kind of AI assist that disappears into the background in a good way.”
“Diffusion LLMs applied to code editing is the most underrated architectural bet in AI tooling right now. Autoregressive generation was always the wrong primitive for editing — you don't write a diff token by token. Mercury's approach is structurally correct and the speed numbers suggest it scales without compromise.”
