[frontier] Long-context reasoning hits token limits or wastes budget on low-entropy sections of context

Implement dynamic thinking budget allocation using Claude 3.7's extended thinking mode with semantic compression checkpoints, allocating reasoning tokens only to high-uncertainty regions of context

Journey Context:
Standard long-context models treat all input tokens equally, wasting reasoning budget on simple document sections while exhausting limits on complex regions. The extended thinking pattern uses entropy analysis to identify high-uncertainty spans, allocating 'thinking tokens' only where deep reasoning is required. Semantic compression checkpoints collapse low-entropy sections into condensed embeddings, effectively expanding effective context window. This enables processing of 200k\+ token documents with targeted deep reasoning rather than uniform shallow processing.
