Agents
TaglineDescribe software in natural language, watch an AI agent write, run, and improve it.No-code AI orchestration platform built for graph-native pipelines in drug discovery and enterprise analytics.
CategoryAgentsAgents
PricingFree· Free and open source under MIT license. Users pay only for the underlying LLM API calls (OpenAI, Anthropic, Azure OpenAI) or run local models at zero token cost.Enterprise· Contact sales; no public pricing
ModelOpenAI GPT (default), Anthropic Claude, Azure OpenAI, and open-weights models like WizardCoder via configurationMulti-model (LLM agents + GNNs + NVIDIA BioNeMo)

Pros
  • Fully open source (MIT) with a small, readable codebase that's easy to fork or study.
  • Model-agnostic: swap OpenAI, Azure OpenAI, Anthropic, or local open-weights models.
  • Zero platform cost — you pay only for tokens, or nothing at all with local models.
  • Simple CLI-first workflow (`gpte <dir>`) that scripts and CI can call.
  • Built-in improve mode for iterating on existing code, not just greenfield generation.
  • Preprompt customization lets you retune agent behavior without patching source.
  • Ships with benchmarking against APPS and MBPP for coding-agent research.
  • Graph-native: first-class GNNs and knowledge graphs, not bolted on
  • GPU-accelerated via NVIDIA cuGraph and BioNeMo integrations
  • No-code workflow builder usable by non-engineer domain experts
  • Pre-built pharma pipelines shorten time to first model
Cons
  • Repository was archived in April 2026 — no active maintenance, bug fixes, or new model support.
  • Best suited to small greenfield projects; struggles on large multi-file codebases.
  • No IDE integration — lives entirely in a terminal with a text prompt file.
  • Requires bring-your-own API keys and manual configuration for non-OpenAI models.
  • Python 3.10-3.12 only; older environments are unsupported.
  • Newer agents (Aider, Cursor, Claude Code, Cline) have overtaken it on both quality and DX.
  • No public pricing; enterprise sales cycle required
  • Current 2000:MM version is not open source (older 5.x is)
  • Narrow sweet spot outside pharma, finance, and retail verticals
