Compares open-source models MiniMax-M2 and Kimi-K2 against Claude Sonnet 4.5 for code generation tasks using CometML's Opik. Results show open-source models perform comparably while offering significant advantages: MiniMax-M2 runs twice as fast at 8% of the cost with only 10B activated parameters. Also covers Agentic Postgres by Tiger Data, which adds agent-ready features like instant database branching, built-in MCP server, hybrid search, and memory-native capabilities. Includes a technique for determining whether gathering more training data will improve model performance by training on cumulative subsets and plotting validation curves.
