Virtual Cell LLM

A language model for single-cell biology. Cells are encoded as token sequences:

A-126 B-090 C-058 D-133 E-074 F-053

Quick start

# Generate a cell from features
python call_api.py "Given the following cell features:\n\n[CellType] neuron\n\nProvide a cell language token sequence.\nReturn ONLY the tokens.\nNo extra text."

# Understand a cell from tokens
python call_api.py "The following tokens encode a cell\n\nA-168 B-090 C-005 D-069 E-232 F-196\nConstruct a requested feature summary based on this encoding:\n\n[CellType][Identity-Associated TFs][General TFs][Ligands][Receptors][TopExpressedGene]\nReturn ONLY canonical feature entries.\nIf a feature cannot be inferred from the tokens, use \"NA\".\n\nDo not provide additional text."

# Ask biology questions
python call_api.py "What transcription factors are associated with T cell identity?"

Useful flags

• --max-tokens N Max new tokens to generate (default: 2048)
• --temperature F Sampling temperature (default: 0.7; lower = more deterministic)
• --url URL Override server base URL (default: ngrok endpoint)
