A Reddit user is seeking recommendations for a local large language model capable of generating high-level and low-level software designs. The workflow involves using existing templates, cross-referencing code, and integrating with agentic frameworks like OpenCode via MCP to fetch data from Confluence and Jira. The user currently relies on Opus 3.6 through Kiro-cli but requires a solution that ensures data privacy. Key technical constraints include the necessity for at least 256k context length and strong reasoning capabilities. The poster questions whether hardware such as four RTX 3090 GPUs is necessary to achieve this level of performance locally.
