Meet our Handshake AI summer intern class. They found us on Handshake. Now they're building what's next on it. Welcome to the team. 🙌

We built a better way to grade agentic work. Gandalf is a reactive agent-as-judge that inspects files, tool state, and artifacts the same way a human expert would. On our banking benchmark, even the cheapest Gandalf config beat the next-best verifier at ~10x lower cost.

Grading agent rollouts in rubric-graded RL environments is itself a hard task. Prior approaches pass serialized artifacts or agent trajectories to an LLM judge; this loses information / doesn't support sophisticated criteria. In contrast, we built a reactive agentic judge.

Agent evals are becoming foundational infrastructure. @jomulr joined @CAISconf’s RLEval workshop to share Handshake’s perspective on RL environments, evaluation, and why @harborframework is emerging as the framework.

Packed room to hear @alexgshaw and @ryanmart3n break down how @harborframework grew into *the* framework for RL environments. In our RLEval workshop at @CAISconf today, attendees tackled big open challenges in RLEs & Agent Evals + I shared the approach we take at @joinHandshake

Kudos to @anishathalye and @jomulr for co-chairing the RL agentic benchmarks workshop track for the inaugural ACM CAIS conference this week. We presented two separate Handshake AI Research papers in: (1) AI agentic systems - first evaluation of grader frameworks, and (2) AI

This spring, we worked with @OpenAI to launch the Codex Creator Challenge. More than 1,500 students built something on their own terms, driven by their own ideas. That kind of confidence and creative ownership is exactly what the most forward-thinking employers are hiring for.

Demo gods were on my side for this guest lecture on AI Agent Security at @MIT_CSAIL: I was able to show a prompt injection attack against @AnthropicAI's Opus 4.6 model. Agent security is still an unsolved problem!

This @joinHandshake event with @OpenAI was so energizing. Not surprisingly, when you give young people powerful tools, their creativity and ambition run wild. The @UCBerkeley students were incredible. With AI, your career will be more about showing than telling. Build something

85% of seniors use generative AI. Now they're building with it too. So proud to see @UCBerkeley students turn curiosity into craft at the Codex Creator Challenge with @OpenAIDevs. 🙌

AI models are incredible at coding and math. Labs like OpenAI and Anthropic solve verifiable domains by teaching models with tasks that have clear right or wrong answers, like "5/2." But in domains like finance or law, there is rarely a single right answer. There, labs turn to

Does an imperfect verifier break reinforcement learning with verifiable rewards (RLVR)? Turns out it doesn’t! Why does this matter? As the world moves into reinforcement learning in semi-verifiable domains, perfect verifiers don’t exist. We added controlled and LLM-based noise
