Context and Token for Professional Chain Investment Research

What this category of data looks like

Professional chain investment research data is sourced from store operation systems, supply chain management platforms, member management systems, and public business district survey materials. Data update rhythms fall into three categories: real-time (member consumption, same-day foot traffic), daily (store revenue, inventory), and weekly (supply chain restocking, competitor dynamics). Document structures include structured store operation reports with fields such as store ID, date, sales revenue, foot traffic, and SKU sales volume. They also include semi-structured monthly operation analysis documents, and unstructured store inspection records and business district analysis notes. Field units include yuan, person-times, square meters, percentage, and others. Single long documents can exceed 10,000 characters.

Constraints imposed on context and token processing

Multi-source, multi-rhythm chain investment research data requires context recall to cover both real-time and historical data. This often leads to total token usage exceeding model upper limits. Single long documents exceeding 10,000 characters will trigger context length limit errors directly if passed without splitting. When batch analyzing multiple stores, a single round of tasks may need to recall dozens of structured reports. Total context tokens will accumulate quickly, exceeding the window limits of standard models. Frequently updated data requires frequent context refreshes. If recall scope is not restricted, old data will consume excessive token resources. This prevents new data from being effectively included in analysis.

How to set configurations

Configuration Item	Recommended Value	Rationale
`maxContext`	12000–15000 characters	Matches the total length of monthly operation reports and business district analysis documents for 3-5 stores. Prevents single-round recall overflow
`segment length`	800–1000 characters	Splits long documents over 10,000 characters. Adapts to the token upper limit of single-round AI processing, prevents single-segment overflow
`recall count`	Top 6 entries	Limits the number of context recall entries during batch analysis, reduces invalid token usage
`similarity threshold`	0.75	Filters low-relevance historical store data. Only recalls content highly matched to the current analysis topic
`maxResponseTokens`	2000–3000 characters	Matches the output length of batch investment research conclusions. Prevents responses from being truncated early
`maxConcurrent`	2–4 concurrent tasks	Matches the CPU core count of offline servers. Balances task processing efficiency and token resource usage

The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.

Three common mistakes

Phenomenon: After uploading a store operation report containing 100+ SKUs, the AI analysis prompts "context length exceeds limit". Cause: No reasonable segment length is configured. Long structured documents are not split, causing single-segment tokens to exceed model upper limits.
Phenomenon: When batch analyzing investment research data for more than 5 chain stores, task queue delay is too high and some tasks fail. Cause: maxConcurrent parameter is not set correctly. The number of concurrent processing tasks does not match server resources, leading to token statistics and processing timeouts.
Phenomenon: Token statistics function fails after offline deployment. Logs show "get tiktoken dial tcp lookup" error. Cause: Local tiktoken dependency package is not configured, or a firewall blocks external domain name resolution requests.

How to confirm configuration is complete

Upload a test document containing monthly data from 5 stores. Check the number of segments after system splitting to confirm segment length settings take effect.
Initiate a batch analysis task for 3 stores. Check the number of context-recalled documents to confirm recall count settings match expectations.
Run the token statistics test script for offline deployment. Confirm no "get tiktoken dial tcp lookup" errors appear.
Adjust the maxResponseTokens parameter, then initiate an analysis task. Confirm the output result is not truncated early.
