Knowledgator Releases GLiFormer: A 575M-Parameter Encoder That Hits 91.10 F1 on Nested JSON Extraction Without Generating Tokens
Why it matters
A smaller, non-generative encoder model achieves near-frontier performance on structured extraction, suggesting task-specific architectures can compete with large generative models on precision work. Relevant for practitioners choosing between API calls and edge-deployable alternatives.
Key signals
- GLiFormer: 575M parameters
- 91.10 F1 on nested JSON extraction
- Comparison baseline: GPT-5.6-luna at 91.96 F1
- Architecture: encoder-only (no token generation)
- Value grounding in source spans (interpretability)
- GLiFormer Large: 575M parameters
- 91.10 F1 on nested JSON extraction benchmark
- GPT-5.6-luna: 91.96 F1 (comparative baseline)
- Encoder-only architecture (no token generation)
The hook
575M encoder hits 91.10 F1 on nested JSON extraction—without generating tokens. Knowledgator's GLiFormer closes the gap to GPT-scale models on a specific, high-value task.
GLiFormer Large scores 91.10 F1 on nested JSON, near GPT-5.6-luna's 91.96, while grounding every value in source spans.
