⚡️Xiaomi has launched MiMo Code (4.3k⭐)
It is an open-source coding agent built on top of OpenCode.
The package includes MiMo Auto, a temporarily free mode on MiMo-V2.5 with up to a 1M-token context. You can also sign in via Xiaomi MiMo, import a Claude Code config, or connect other providers.
What’s interesting:
▫️ Max Mode
At each step, the agent creates 5 independent drafts: reasoning tool-call plan, without execution. Then a judge selects the best option, and only that one gets executed.
Xiaomi reports 10–20% on SWE-Bench Pro, at the cost of roughly 4–5x more tokens. The feature is experimental.
▫️ Goal
/goal defines the stopping condition. Before finishing, a separate judge checks whether the task has actually been completed.
▫️ Memory
Memory is handled by a dedicated checkpoint-writer. It writes checkpoint. md, promotes stable facts into MEMORY. md, stores the full trace in SQLite, and parses notes. md, where the main agent can drop findings.
When the context fills up, the session is rebuilt from the todo list, checkpoint, latest user messages, and memory. That is their version of “unlimited context.”
▫️ Compose
A separate mode next to build/plan. Essentially, it is a built-in flow in the style of Superpowers skills.
The Compose agent runs the task through skills like compose:brainstorm, compose:plan, compose:tdd, compose:execute, compose:review, compose:verify, and compose:merge.
It is like specs-driven development: from spec to implementation, checks, and merge. In other words, they baked the development process right into the harness - respect for that.
▫️ Dynamic Workflow
For large tasks, there is JS orchestration: agent(), parallel(), pipeline(), workflow(). Parallel subagents and process logic live in an executable scenario, so complex flows depend less on whether the model can keep the order of steps in its head.
▫️ Dream / Distill
Dream cleans and merges project memory every 7 days.
Distill looks for recurring processes every 30 days and turns them into skills, commands, agents, and SOPs.
This looks like one of the most interesting new coding agents: Xiaomi has built an agentic system for long-running tasks with memory, completion verification, an SDD-style development mode, and parallel orchestration.
One nuance: you will not see the GPT-5.5 model right away, because they use a plugin for ChatGPT OAuth that does not include this model. But MiMo GPT-5.4 itself managed to make a patch, after which the model became available.
