3. Pyrite is our frontier firmware simulation model, currently available to select partners and users. You gain full access to the binary so users can run simulations locally, and develop applications like CI/CD pipelines, or agent harnesses with. Please contact us at [email protected] for access.

2. Simantic Bot is the first AI code reviewer made for firmware. The reviewer agent identifies the hardware platform, build system, and the changes are made in the code based on the diffs and comments. What makes it different from other code reviewer bots is that it actually runs your code on a simulated version of the microcontroller, and inputs to peripherals like CAN, UART, Ethernet, and BLE can be simulated according to different scenarios. Check out a demo here:

1. Cloud Sim is the first virtual devboard you can program and run entirely from your terminal with zero setup, using simple curl commands. All you need is the MCU model and compiled ELF binary. simantic.com/cloud-sim

Simantic is the simulation layer that lets engineers and AI agents test and validate firmware at the speed of software. Frontier AI models have made generating firmware code cheap and effortless, but testing still depends on manual hardware debugging, expensive equipment, and software designed more than a decade ago. Simantic is modernizing firmware testing with simulation built for the era of coding agents. w/ @ycombinator @shong0504 @enough_ahnaf

Firmware testing doesn't have to be a hardware problem. We made it into a software problem with simulation!
We're launching Greptile for firmware. AI code reviewers are great for catching bugs in software, but when it comes to firmware, they miss critical bugs in ISR and peripheral timings, and runtime memory. We're launching Simantic Bot to fix that. We gave AI the ability to run firmware in simulation, and test scenarios like providing external outputs from sensors and wireless communication, all inside your Github PRs.
