Download paper ↗OSH is a new autonomous computational architecture that gives a machine an internal condition that continues, a way to evaluate change and a path from selection to physical action. Its validated causal route runs locally on microcontroller silicon.

OSH is a homeostatic semantic organism: a computational architecture with its own evolving internal state. A signal changes that state, attention evaluates possible paths, and selection connects the process to meaning or physical action. What happens in one cycle can shape the next.
Most people see a machine react to an input. Inside OSH, the relevant starting point is its current endogenous condition. New signals alter a trajectory; the result is not treated as an isolated request.
The Homeostatic Attention Loop (HAL) evaluates candidates against that changing condition. A selector then chooses an edge in compact semantic structure. Language can express an outcome; it does not direct the tested route.
In the validated ESP32-S3 experiment, physical input perturbed OSH, the local route selected an action, and a real circuit returned feedback. The paper checks five internal causal levels against the PC reference.
It is a new architecture, not an LLM, a remote API or a prompt-driven agent. Its defining mechanism is persistent state, trajectory, homeostatic attention and selection, operating locally without cloud inference for the validated route.
A sensor reading, an internal need or another perturbation enters a mechanism that already has a condition and a history. Select each stage to see how the cycle develops.
OSH began as a resident architecture on a computer. The next question was whether its mechanism could be carried beyond that machine and still preserve the behavior it was built to produce. Explore each step, then open the actual measurements below.
Develop the causal path → carry its frozen core across targets → verify the original behavior on another ISA → test the route on real ESP32-S3 hardware.
Benchmark 3 measures OSH on a CPU-only Intel Atom D2500. It records 30 structured inputs and a resident runtime. This is a PC result, not a microcontroller timing claim.
Watch the PC recording and read Benchmark 3A frozen OSH computational substrate and its original validation harness. Virtual RISC-V execution and physical ESP32-S3 execution are separate tests. The ESP32-S3's main CPU is Xtensa; the RV32IMF result is a virtual cross-ISA test.
This is the first measured stage of the OSH journey. The recording shows José Fabián typing in the real OSH PC interface. The report measures its resident runtime on an Intel Atom D2500 under a controlled 30-input protocol.
The recording shows the conversation and the OSH / STRUCTURAL TELEMETRY panel. It documents the interface in use; the reproducible measurements are in the report.

The comparison measures runtime and Working Set under the stated protocol: TinyLlama was limited to one token per input. The computational tasks differ; the ratio does not measure intelligence, language quality, or equivalent task performance.
A migration you can trace
OSH began on a PC. In plain language, this benchmark asks whether its same core can be translated for many processors and still reproduce the expected behavior on a different instruction set. The frozen Tier-A code compiled across target profiles; its original validation harness then passed on a virtual RV32IMF. These steps established a portable core to carry into the physical ESP32-S3 validation documented below.
The original SHA-256-verified Tier-A core and header generated objects for 21 of 22 profiles across x86, ARM, RISC-V, MIPS, PowerPC, SPARC, LoongArch64 and WASM32. The tested m68k profile failed; object generation alone does not prove physical execution on those targets.
The original Tier-A harness ran on an emulated RV32IMF and passed both golden cases, OSH_PRESENCE and OSH_NO_ACTIVATION. Maximum absolute error was ≤5×10⁻⁸ against the existing 10⁻⁶ threshold; the observed Top-K candidate order held. Physical ESP32-S3 results are documented separately in the technical paper below.
Other target families now have a concrete path to investigation. Each future board still needs its own execution, causal-parity, timing, power and integration tests; compiling a profile is the first step, not the final proof.
After the PC baseline and portability checks, the physical paper verifies the architecture’s tested causal route on two real ESP32-S3 boards: state, trajectory, attention, selection and meaning, followed by action through an analog feedback circuit. Explore the measured results, their limits, and the new board-level power observation.
The portability work tested the frozen computational core beyond the PC. The physical paper then documents native OSH execution on two ESP32-S3 units and 150/150 PC–MCU causal-parity checks across state, trajectory, HAL candidates, selected edge and meaning. The validated route also drove PWM, received analog feedback and completed 100,000 cycles.
The paper validates the tested architecture route on ESP32-S3 silicon. It does not claim that every interface, physical modality or other target board has been validated.
B25K reference → ADC GPIO3 → OSH → PWM GPIO14 → external 1 kΩ / 100 µF network → ADC GPIO2. The policy exercised all three observable actions.
INC 5,160 · HOLD 93,358 · DEC 1,482. PHYSICAL_100K_GATE and FINAL_LATCH: PASS. An oscilloscope image preserves a representative 23.0 µs path pulse; this is a separate measurement method and does not replace the internal mean.
Thirty cases were examined at each of five boundaries: C/P/X/T/H state, trajectory and vortex, HAL candidates, selected edge ID, and meaning.
The tested path preserved intermediate identity. This does not establish general reasoning or speech quality.
Open technical paper ↗The physical paper follows OSH from the PC reference through five-level causal parity and a closed analog feedback loop on ESP32-S3. The universal benchmark separately validates frozen Tier-A cross-target compilation and original-harness execution on an emulated RV32IMF.
The paper does not document physical execution on other boards, a complete production stack migration, or live physical I2S and Wi-Fi/HTTP validation. Those require separate tests; no claim of general intelligence or consciousness is made.
Review portability evidence ↗With USB power disconnected, the physical ESP32-S3 setup was powered directly from a UNI-T UTP3315TFL-II regulated bench supply. The display held at 4.97 V and 0.027 A for five minutes.
Measurement boundary: complete board-level physical setup. This is not isolated SoC power and not a logged high-bandwidth energy-per-decision measurement.
Select a stage to see its role and the evidence boundary that supports it. State persists; each input affects a trajectory rather than an isolated response.
A signal from the environment or system perturbs persistent state. In the physical experiment, an analog reference enters through GPIO3 and feedback returns through GPIO2.
To make a product respond to changing conditions with a resident internal state, local selection and a physical action path. OSH Global Systems can package that architecture for a specific device, prove it on the buyer's hardware, then participate in the value of every product shipped.
Its causal route has run on physical ESP32-S3. Its frozen core has generated objects for 21 of 22 target profiles, and the original harness passed on virtual RV32IMF. That progression makes new board integrations worth pursuing; each new target gets its own physical qualification.
Trace the evidence pathSelect a deployment to see the buyer, the concrete job and the proposed commercial relationship.
An equipment maker could evaluate OSH as a resident supervisory path that tracks internal condition and selects an action as sensor conditions evolve. A pilot would compare its decisions against the existing process and measure the effect on operations.
A deal begins with one device and one measurable outcome. These are the value equations a pilot can fill with the buyer’s data.
