Language Model Tech Tree Maps LLM Evolution

Useful as a navigational chart, not a canonical history. Its value is in collapsing a messy decade of model releases, papers, and architectural shifts into one scannable reference, but any “tech tree” will inevitably reflect the author’s judgment calls and omissions.

• –Strong onboarding aid for people trying to understand how seq2seq, attention, transformers, instruction tuning, and reasoning-era models connect
• –The CTX, Arch, and Size B columns make it more practical than a pure timeline or poster
• –Including both open-weight and closed-weight branches is the right framing for today’s LLM landscape
• –The editable draw.io file matters more than the image because it can evolve as the field keeps moving
• –Best used as a study aid for model lineage, not as an exhaustive literature survey
