Founder GuidesI Modeled What $20,000 a Month on Devin Actually Buys a Solo Founder
A solo founder's public breakdown of spending $20,000 in a month on the Devin coding agent is a useful stress test for how any founder should think about AI-agent ROI, not just whether the number sounds high.
Founder GuidesLLM VRAM Sizing: Your Context Limit Is a Pricing Decision
Llama 4 Scout needs about 231 GB of VRAM at a 1,024-token context and about 3,671 GB at its advertised 10M-token window, so the context length you configure sets your hardware bill more than the model size does.

Founder GuidesGLM 5.2 vs Opus: Should You Swap Your Coding Model to Cut Costs?
Swapping a premium model like Opus for a cheaper open-weight model like GLM 5.2 can cut your AI bill sharply, but only if it clears the quality bar for the specific work you actually run.

The durable fix is not rationing tokens after the overspend, it is modeling cost per task up front so every team gets a budget tied to real unit economics.
Founder GuidesSelf-Hosting vs API: When Local LLMs Actually Cost Less
