Report #61300
[cost\_intel] Long context windows triggering non-linear pricing tiers and attention degradation
Keep working context under 8k tokens when possible; implement sliding window summarization for RAG; avoid 100k\+ contexts for multi-turn conversations; use Claude 3 Haiku for context compression passes
Journey Context:
While providers appear to charge linear per-token rates, effective cost scales super-linearly due to: \(1\) Pricing tiers \(Claude 3 Opus: $15/$75 per million tokens at 200k context vs $3/$15 at 4k\), \(2\) Quadratic attention compute causing providers to pass through costs, \(3\) 'Lost in the middle' degradation forcing you to resend or re-retrieve. Real impact: Processing a 200k document with Claude 3 Opus costs $15 input per query vs $3 for 4k context—a 5x jump for 50x tokens, not 50x cost. But quality degradation at 200k means you often need 2 passes, making effective cost 10x. The signature you need smaller context: the model misses information in the middle of documents or confuses details from different sections.
