Sub-second agentic coding for edits, refactors, and high-throughput inline completion. Built on DeepSeek V4 Flash, hosted in the US.
The Astrophysical Journal accepted our AI's FRB discovery after three rounds of peer review, but the AAS editorial office then halted the paper over an AI-disclosure review, not the science.

Dropstone Fast is the tier you reach for thousands of times a day: inline completion, file-scoped edits, quick refactors, test stubs. It pairs a frontier open-weight base with the same approval-gated CLI as every other tier, so velocity never costs you a security boundary.
Sub-second suggestions that respect your repo conventions. Designed for thousand-keystroke workflows.
Rename, refactor, extract. Fast enough to feel like an IDE primitive, not a network round-trip.
Generate unit-test skeletons against the function under the cursor with the same approval gate as any other tool call.
Every Dropstone request is treated as if the model could be adversarial. The CLI requires explicit user approval before any action that writes to disk, runs a shell command, or fetches a URL. No model output is ever auto-executed.
Fast runs on SOC 2-certified, US-based inference providers. Prompts and completions are not retained, not used for training, and not shared with the model's original operator.
Fast is built on DeepSeek V4 Flash, an open-weight foundation model. Goldwasser et al. (2022) proved no party can prove a closed foundation model is free of embedded behaviors, including Anthropic for Claude and OpenAI for GPT. We say this out loud. The runtime is why model origin does not matter for your code.
Same approval gate, same US-hosted inference, same zero-retention guarantee across all three. Pick the smallest model that meets the task.
