Mercury Coder Next Edit
Sub-100ms next-edit prediction for VS Code and JetBrains — powered by diffusion LLMs

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.

Ogoron is an AI-powered end-to-end QA automation platform that claims to replace the full stack of traditional testing roles—systems analyst, test analyst, QA engineer—with autonomous agents that generate, maintain, and run tests continuously. Rather than manually writing test cases that rot as your product evolves, Ogoron watches your product change and updates its test suite automatically. The pitch is squarely aimed at fast-moving small teams who are shipping too quickly to maintain a QA function but can't afford to break things on every deploy. The platform's headline metrics (9x faster, 20x cheaper) track against hiring a human QA team, not against existing automation frameworks like Playwright or Cypress—a distinction worth noting when evaluating the comparison. Launching on Product Hunt today (April 6, 2026), Ogoron is one of a new wave of AI QA tools competing with Momentic, Reflect, and Checkly. The free tier and the fully managed approach lower the barrier compared to open-source testing frameworks, making it accessible to teams without dedicated DevOps expertise.
Reviewer scorecard
“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.”
“For a solo founder or two-person team shipping fast, the traditional QA workflow simply doesn't exist. If Ogoron can automatically generate and maintain tests that catch regressions—without me having to write a single Playwright spec—that's a massive unlock. The free tier means low risk to try it.”
“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.”
“Auto-generated tests are only as good as what they assert. The hard problem in QA isn't writing tests—it's knowing what to test and what the correct behavior looks like. Ogoron's AI will generate test cases but it doesn't understand your product's business logic. Expect false negatives on the edge cases that actually matter. Momentic and Reflect have months of production feedback; Ogoron launched today.”
“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.”
“The vision of a software product that continuously validates itself against its own spec—automatically—is genuinely transformative. QA as a job function is one of the clearest near-term displacement targets for AI agents. Ogoron is early, but the category is real and growing fast.”
“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.”
“I build with no-code tools but still need to verify that my automations work after every update. If Ogoron can watch my app and tell me when something breaks without me setting up infrastructure, that's huge. The 'end-to-end' framing suggests it tests actual user flows—which is what I actually care about.”
