The most interesting sentence on Jcode's website isn't about intelligence or model quality. It's a memory benchmark: ten Jcode sessions cost about 100 MB of RAM, less than half of a single Claude Code session. That single number, if it holds up in real world use, changes the economics of AI assisted development. For months, the default way to use a coding agent has been one at a time: you watch a session work through a task, wait for it to finish, then hand it the next one. Jcode's bet is that this is a self imposed bottleneck. The real lever on productivity isn't a smarter model—it's parallelism. Run a dozen agents at once, each on a different task, and you get a dozen times the output. The only reason this hasn't been the default is that agents are memory hogs. Jcode attacks that problem head on, and it's backed by Y Combinator.
