Specification for a reproducible, provenance-bound multi-lane LLM benchmark suite.

What 200 steps of fully simulated multi-turn tool-use RL do to a 4B policy: every 10th checkpoint scored on BFCL v4, with the pipeline that produced the measurement.

Public benchmark harnesses and reproducible evaluations from PixelSpaceAI

Pre-generation tool-call gating via linear probes on LLM hidden states. F1 ≈ 0.91–0.94 on BFCL v4, 14–22× faster than full generation. Cross-architecture transfer across Llama / Qwen / Phi / Mistral (3B–7B) with ≥96% retention.

Think only when the tool call looks unsure: confidence-gated reasoning for small local models. Code, BFCL results and paper.

Canonical IR, schema validation, and deterministic delivery for function calls.

A bf16 LoRA fine-tune of Qwen 3.5 4B for function calling on xLAM. v1.0 ships below the BFCL gate with full per-category failure analysis.

Reproducible LoRA SFT of Qwen3-4B-Base for tool calling on 2x RTX 4090: assistant-only loss + selective special-token LoRA (810M to 66M trainable), 124k-sample pool, decontamination, 3 eval suites incl. BFCL v4 subset. Strict protocol success 1.8% -> 35.0%.

Paired metamorphic evaluation of tool-calling robustness under realistic user phrasing, built on BFCL.

Task-conditioned tail reliability for tool-using agents under equivalent interfaces

Post-training, BFCL evaluation, and single-L4 vLLM serving benchmarks for Qwen3.5-2B.

Self-hosted LLM evaluation lab: MMLU-Pro / BFCL / IFEval / LiveCodeBench / HumanEval+ runs on Tesla V100 and RTX 3090, llama.cpp serving (incl. Volta sm_70), patched API benchmark clients

Does quantization break tool calling? 10,800 graded agent tasks: it depends which Gemma 4 you compress. The 26B MoE stays flat down to 2 bits, the dense 12B collapses, and no static benchmark reveals it.

Independent audit of a fine-tuned LLM tool-calling PoC — BFCL regression decomposition, inference stack risk assessment, and production recommendation for a FinTech client. Qwen-2.5, LoRA, SGLang, H100.

Post-train a small instruction-tuned LLM for reliable multi-step tool use

面向工具调用的大模型后训练与泛化评测系统。 End-to-end tool-calling LLM post-training pipeline with data auditing, QLoRA SFT, grounded on-policy DPO, strict evaluation and BFCL.

AAFV: Agent Architecture Feedback Validator

QLoRA fine-tune of Qwen2.5-1.5B for tool calling on one 8 GiB GPU, scored locally on BFCL v4 tasks: up to +8.5 points on call categories, -55 points on declining. Replacing 1,200 call examples with refusals recovers ~49 of those (3 seeds; irrelevance still 5-9 points below base). Appending them instead ends +4.1 points over base overall.
