H2LooP

Civilization runs on system software. It cannot fail. Most AI coding tools were not built for this domain. H2LooP was. #h2loopai #EmbeddedSystems #SystemSoftware #AIInfrastructure

15 years running turnkey aerospace and defense programs. Ground, naval, airborne. National stakes. He joins H2Loop as Chief Growth Architect. His vision: take us from lab to mission. #DefenseTech #SovereignAI #h2loopai

5,907.27 tok/s on one Tesla T4. The winner of Bear the Tokens: Ratan Kokal. An aerospace undergrad at IIT Bombay. Baseline was 3,332. Faster inference on the same GPU means more requests per dollar. He got past it with serving-engine changes and one observation most people will miss. Dhruv used an inferencing plugin. Aaditya applied AWQ quantization. #h2loopai #LLMInference #GPUOptimization #Quantization

Flat‑rate AI coding was a hidden surcharge on Curiosity. Vendors subsidized compute to capture your corrections. Now they are pushing programmatic workflows to expensive API rates. GitHub Copilot switches to usage-based billing on June 1. Anthropic redefined interactive use to block third-party tools. Cloud pricing penalizes complex system engineering. A single autonomous coding session can burn $30. Unpredictable token billing destroys budget forecasting. Running models on-premise converts variable API fees into fixed capital expenses. You own the model. Your compute costs stay flat. #SovereignAI #CloudCosts #VendorLockIn #h2loopai

Hydron is live. AI for embedded engineers. Code grounded in your datasheet, your codebase, and your hardware context. VS Code + terminal. v1, fresh out of beta. A lot works. A lot will get better. Bring your worst MCU. hydron.sh

Bear the Tokens leaderboard: 5,066 tok/s on a single T4. Qwen2.5-0.5B. 50 concurrent requests. One Colab to enter. Submissions open till 1 June. Final deadline. PS5 + Claude credits for the winners.

For anyone shipping sensitive IP, that trade needs to be a conscious decision, not a default setting. On-prem and air-gapped exist for exactly this reason. #VibeCoding #Lovable #AISecurity #SovereignAI #ClaudeCode

Two coding platform leaks in a month. Lovable: a BOLA flaw let any free account read source code, credentials, and chat histories across other users' projects. Claude Code: an internal sourcemap shipped in a public npm release, exposing roughly 500,000 lines of Anthropic's own code.

Different companies, different failure modes, same headline. The platforms holding your IP cannot reliably hold their own. Every productivity gain from these tools comes with an implicit trade. Your source code, your credentials, your prompts, handed to a vendor whose recent track record says they cannot be trusted with it.

The current inference record on a Tesla T4 is 3,332 tok/s. We want someone to break it.

Prizes: PS5 for first place. Claude Code for top performers. Verified high scorers get a direct path into H2Loop. No interview, your benchmark is the application.

Optimize however you want. Quantization. Flash attention. CUDA graphs. KV cache tuning. Speculative decoding. Anything that does not touch the harness is legal.

Bear the Tokens: one GPU, one model, one fixed workload. Qwen2.5-0.5B. 50 concurrent requests. 512 in / 512 out tokens. The eval harness does not move.

H2LooP Spark CPT (Preview) is available now on HuggingFace under a Research Only License. Works with vLLM and 🤗 Transformers. Single H100, bfloat16. This is an early checkpoint Paper → arxiv.org/abs/2603.11139 Request access → huggingface.co/h2loop-ai/spar…

Introducing H2LooP Spark: the first domain-specialized autocomplete model for embedded software. A 7B model that beats Claude Opus 4.6 and Qwen3-Coder-30B on embedded code completion. Not fine-tuned. Continually pre-trained on 23B tokens of firmware, datasheets, and vendor SDKs

We built SpecMap: an agentic pipeline that maps vendor datasheets directly to code symbols, across 13 embedded domains 100B raw tokens curated down to 23B. The result: a model that knows the exact register offset, the exact intrinsic opcode, and the exact pin mapping.

General LLMs fail at embedded code because - Infineon TriCore intrinsics - NXP eDMA scatter/gather docs, and - AURIX ATOM timer pin maps simply don't exist in standard pre-training data.
