Solidity-Master 2

Solidity-Master 2 is a Large Language Model (LLM) specialized in Solidity smart contract development.

Built upon Qwen3-Coder-30B-A3B-Instruct, Solidity-Master 2 is fine-tuned using a large-scale corpus of Solidity source code collected from the Ethereum Mainnet and GitHub. The model is optimized for Solidity code generation, completion, and understanding.

To keep pace with the rapidly evolving Ethereum ecosystem, Solidity-Master 2 is continuously improved through monthly data collection and incremental fine-tuning.

Key Features​

  • Built on Qwen3-Coder-30B-A3B-Instruct
  • Fine-tuned using Solidity v0.8.20+ source code
  • Optimized for Solidity smart contract generation and completion
  • Trained using verified Ethereum Mainnet contracts and high-quality open-source GitHub repositories
  • Updated monthly through continual fine-tuning with newly collected datasets

Availability​

Solidity-Master 2 is available across HPP's products:

  • HPP Router — call it by the model id ollama/solidity-master:2 (currently free). See HPP Router and Models & Pricing.
  • HPP Hub Playground — pick solidity-master:2 in the model selector to chat with it. See the Playground guide.
