Sundar Baskaran developed and stabilized advanced deep learning workflows in the tenstorrent/tt-forge-models repository, focusing on autonomous driving and large language model deployment. He engineered end-to-end PyTorch pipelines for models like UNIAD and Transfuser, integrating sensor fusion and optimizing inference reliability. Sundar enhanced loader scripts to support multi-variant models such as Gemma3, Solar_10.7B, and Qwen2.5-72B, improving production readiness and test coverage. His work addressed memory and runtime issues, refined input handling with padding and prompt engineering, and improved model evaluation metrics. Using Python, PyTorch, and C++, he delivered robust, maintainable solutions that reduced deployment risk and improved validation consistency.
March 2026 monthly performance focused on expanding multi-variant model support, stabilizing decode flows, and reinforcing production readiness for tt-forge-models. Key outcomes include cross-variant loader script enhancements enabling Gemma3 multimodal variants, Solar_10.7B, and Qwen2.5-72B brings-ups with variant-specific loading/config; and decode prefill improvements that reduce PCC variance and prevent attention collapse during validation.

December 2025 — Monthly performance summary for tenstorrent/tt-forge-models. Key features delivered include padding-enabled inputs and improved prompts for Phi2/Phi3, resulting in significantly higher PCC scores across variants. Specific gains include Phi2 causal_lm with padding achieving PCC ~0.9965; Phi3 mini-instruct (4k) PCC ~0.9838 and (128k) PCC ~0.9693 after prompt/input updates to mirror the official Hugging Face example. Additional improvements for Phi3/5 variants entailed refine input generation and padding, enabling the model to pass verification after updates. Major bugs fixed span PCC drops observed across multiple models: Phi4 adjusted with padding enabled, achieving PCC ~0.99957 in testing; Gemma-1.1-7B PCC drop resolved through padding and chat templates (PCC ~1.0563). Phi3 family refinements (including Phi3_5 and token_cls variants) were aligned via apply_chat_template and consistent padding, resulting in all targeted models passing in tests. Overall impact: The changes substantially raise model reliability and consistency of PCC results across the data pipeline, improving confidence for production deployment and downstream decision-making. The work reduces risk of PCC degradation due to input handling, and provides a more robust, auditable testing trail. Technologies/skills demonstrated: Advanced input handling with padding, prompt engineering based on official Hugging Face prompts, input generation tuning via loader.py, use of apply_chat_template for consistent prompts, test harness validation across Phi2/Phi3/Phi4/Gemma-1.1-7B, and thorough log collection for traceability.
