Context window truncation loses critical information

6/10 Medium

Gemini API has a hard cap on input length that truncates important data from the end of requests. In testing with 80 customer feedback forms, the API missed shipping delay complaints entirely because they appeared in the last 20% of the text, and this limitation is not flexible.

Query: “What are the most common pain points with Anthropic API for developers in 2025?3/30/2026

Context window is not free memory. A 200K context window does not mean you should fill it. Retrieval quality degrades on very long contexts (the "lost in the middle" problem). For documents over 50K tokens, use RAG to retrieve relevant sections rather than stuffing everything into context.

I wanted to know the most common complaints. It missed shipping delays entirely—those mentions were in the last 20% of the text. This cap isn't flexible.
