Hello, I am Sankalp Shubham. I am currently working on stuff related to frontier benchmarks and RL environments at Prime Intellect RL residency.
Open to contracts in work around evals, benchmarking (think auditing benches), finding agent swarms (lol), post-training in rl environments, auto-research adjacent, evals and possibly contributing to SOTA benches related work rn.
In general, I have been in an exploratory phase (mostly post-training) since May'26. I started off with LLM-RL fundamentals (thank you Nathan Lambert!), then got into RL environments, training and infra these days. I am also familiar with inference optimisation and kernel optimisation (close to an expert if you arm me with a model)
I have previously worked as a founding AI engineer at an early stage startup, done applied AI consulting with multiple startups/individuals and was a backend engineer once upon a time. When I say AI engineering, I mean building stuff with and around LLMs. I liked the definition by Karpathy - context engineering.
+1 for "context engineering" over "prompt engineering".

People associate prompts with short task descriptions you'd give an LLM in your day-to-day use. When in every industrial-strength LLM app, context engineering is the delicate art and science of filling the context window… https://t.co/Ne65F6vFcf
I try to maintain a full-stack understanding of how things work (from attention to application layer) and have contributed professionally across context engineering, LLM evals, agentic code-generation, and voice agents. Coding agents were responsible to draw me to this field.
Featured - Read my top blogs here. They are some of the best you will find on the internet with respect to frontier things. I have also featured on Hackernews Front Page 3 times.
X - best place to contact me. I will try to reply when I get the time and interest.
More about me
I try to stay up to date with latest AI progress and love hanging around with my mutuals on X tracking the same. It's fun plus literally helps me in my job.
If you wanna stay up to date, I have curated a list on X from where you could follow some people and see who interacts with them etc. These consist of my favourite people in AI ranging from research to content aggregation.
I love to play around with models and writing which contribute to my intuition and tacit knowledge around these. My other interests span - distributed systems broadly, post-training broadly, role playing, inference optimisation, search and retrieval, RL environment, and recently have started dabbling more into pre-training research.
I love using AI devtools like Cursor, Claude Code and have used/reviewed several products either for personal usage or as feedback to companies/friends. It's a pity though that I haven't built much in this area in 2025 - unlike last year.
I like to write, shitpost, occasionally watch anime, play table tennis, hanging around with friends in Bangalore's cool weather. Would love to play more video games (Elden Ring is my #1). My favorite band is Men I Trust.
