Best Vibe Coding Tools: What the Community Recommends

Could you build something like Claude yourself, or is it out of reach?

The post asks whether people are trying to build Claude itself or whether it is too hard. Two replies separate the two jobs. Recreating the agent harness around a model is described as doable, while training a frontier model from scratch is described as costing millions or hundreds of millions. One member says fine tuning an existing model for a niche topic is realistic.
