Mimo 2.6 Pro feedback after 7 hours of testing

For some technical context, one of the tasks involved a fairly substantial architecture refactor. I was experimenting with adding a JEV layer on top of a DeepSeek Harness-style agent architecture, using JEV more as a state-space and action-selection layer. This involved changes to the overall architecture, state representation, agent flow, and the interactions between different components. I provided a fairly detailed description of the intended design, constraints, and expected behavior. However, Mimo 2.6 Pro struggled to translate those requirements into a coherent implementation. The second task was more straightforward: build a frontend with a Codex/Harness-style project structure on the left, support multiple folders, and move the chat panel to the bottom. These requirements were explicitly stated, but several of them were still missed in the implementation. Across the two tasks, the model spent around seven hours, and the final results were still far from what I expected. For comparison, based on my previous experience, I would expect Astra to complete tasks of this scope much faster. So my concern with Mimo 2.6 Pro is less about raw capability and more about real-world reliability: understanding architecture-level intent, following detailed requirements, and maintaining consistency across a larger implementation. Its benchmark performance looks strong, but my actual coding experience with it was quite disappointing. preview.redd.it/nauzyjy781rh1.png Do not believe it.
