Chat with many models
Run prompts against OpenAI, Gemini, Mistral, Ollama, and HuggingFace side by side, or bind an agent graph to a chat for richer behaviour.
Chatty the Lab
Chatty the Lab is a research-oriented platform for building and studying multi-agent AI systems. Built at CiTIUS (University of Santiago de Compostela), it pairs a visual agent-graph studio with a full research toolkit: experiments and parameter sweeps, typed datasets, human labeling jobs, and a collaborative logbook — all scoped to personal or team workspaces.
What you can do
Section titled “What you can do”Build agent graphs
A visual canvas (the Studio) with 24 node types and 6 edge types: LLMs, tools, conditions, loops, panels, orchestrators, and more — with real-time collaboration.
Coordinate multi-agent panels
Convene round-table debates (Panel) or hierarchical delegation (Orchestrator) over a roster of agents, each with its own memory and communication policy.
Run experiments
Sweep parameters (grid / random / TPE) over a graph and a dataset, score trials, plot results, and append outputs back to datasets.
Label & annotate data
Typed datasets with CSV/JSON import, plus labeling jobs with roles, custom questions, assignments, and inter-annotator agreement.
Collaborate in teams
Personal and team workspaces scope every resource. Invite members, assign roles, and keep a shared research logbook.
