Model Access and Configuration for Peptide Drug Registration

Data Characteristics for this Category

Peptide drug registration documents primarily originate from regulatory guidelines, technical review reports, domestic and international pharmacopeias, academic journal literature, and internal enterprise experimental data and manufacturing process documents. Data update frequency is relatively stable; guidelines typically revise annually or every few years, and pharmacopeias have fixed update cycles. Document structures are complex, containing extensive specialized terminology, chemical structures, biological activity data, preclinical and clinical trial reports. Field types are diverse, encompassing molecular weight, isoelectric point, purity, batch numbers, and stability data. Units include Da, g/mol, % purity, and IU/mg. Non-structured information such as tables and chromatograms frequently appears.

Constraints from these Characteristics on Model Access and Configuration

The specialized and complex nature of peptide drug documentation places high demands on model access. Extensive unstructured and semi-structured data, such as charts and chemical structures in experimental reports, require the model to possess strong multimodal processing capabilities or to convert these into recognizable text through preprocessing. The periodic nature of data updates means the knowledge base requires regular incremental updates or full reconstruction to maintain information timeliness. The specificity of professional terminology and units, such as amino acid abbreviations in peptide sequences, requires the model to have domain knowledge for tokenization and entity recognition. Without this, inaccurate recall or biased answer generation may occur. Furthermore, the large volume of data and its strong interconnections challenge the knowledge base's indexing strategy and retrieval efficiency, necessitating optimization of chunk granularity and retrieval depth.

Configuration Recommendations

Configuration Item	Recommended Value	Rationale
`Chunk size` (Chunk Size)	`800–1200 characters`	Balances context integrity for peptide sequences and experimental reports, preventing truncation of critical information.
`Recall count` (Recall Count)	`Top 8`	Improves relevance for complex queries, covering multi-source information such as manufacturing processes and quality control.
`Similarity threshold` (Similarity Threshold)	`0.78–0.85`	Balances high recall with low noise, ensuring retrieved results are highly relevant to the query intent.
`maxContext`	`4096 tokens`	Accommodates lengthy review comments and pharmacology/toxicology reports, providing sufficient context.
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Allows ample time to process large PDF documents, such as clinical trial summary reports.
`Rerank result count` (Reranked Recall Count)	`Top 5`	Refines the initial recall results, improving the accuracy of the final output.

Three Common Pitfalls

Knowledge base search returns JSON format errors, failing to be recognized as valid JSON. This occurs when original document parsing incorrectly identifies tables or special characters, leading to corrupted JSON structures.
AI responses display garbled peptide sequences or chemical structures. This happens when model training data lacks support for specific domain character encodings, or when non-standard character information is lost during text vectorization.
When proxyAI and one-api coexist, proxy configuration prompts 404 body not found. This indicates that the model interface address or authentication parameters are not correctly mapped or passed in the proxy configuration, preventing the request from reaching the actual model service.

How to Verify Correct Configuration

Upload and parse typical documents containing peptide sequences, chemical structures, and experimental data. Check if the parsed text content is complete and free of garbling.
Ask questions about specific peptide pharmacological effects, side effects, or preparation processes. Observe if the AI response accurately cites relevant information from the knowledge base and verify the citation sources.
Simulate multiple complex queries concurrently. Monitor model response times to ensure processing completes within the set PARSE_FILE_TIMEOUT_SECONDS. Verify that Recall count (Recall Count) and Rerank result count (Reranked Recall Count) meet expectations.
