Apr 1, 2026April 2026 monthly summary for inclusionAI/AReaL: Enhanced reliability and scalability across CI/CD and inference services. Delivered parallelized CI tests across four GPU runners, updated the GCP OS image for stability, and hardened test data handling. Rolled out HITL-enabled InferenceServiceWorkflow with offline/online rollout, backend flexibility including vLLM fallback, and external model API support with bearer-token authentication. Fixed key data handling and test infrastructure bugs (Content-Type handling, test_train_engine failures, and /data/batch validation) and strengthened test infrastructure. These changes shorten feedback loops, improve deployment reliability, and enable seamless integration with external models, supporting faster time-to-market and improved user experience.

Mar 1, 2026March 2026 (2026-03) highlights for inclusionAI/AReaL. Delivered a data proxy-backed SGLang text generation workflow with a streaming /generate endpoint, integrated into the gateway, enabling text and pre-tokenized inputs, streaming per-token information (IDs, decoded text, logprobs) to improve inference throughput and user experience. Built a robust data proxy stack (DataProxyConfig, TokenizerProxy, SGLangBackend wrapper) and FastAPI endpoints with /health and streaming /generate. In parallel, optimized CI/inference testing to shorten feedback loops by reusing fixtures, relaxing controller batching, and removing brittle tests, enhancing stability without sacrificing coverage. These efforts drive faster feature delivery, higher throughput, and more reliable deployment of text generation capabilities.
