Generator hallucination counts and density
The original ACL report measures hallucination production, response-level detection, span-level detection, and response selection separately. Detection precision, recall, and F1 are percentages; hallucination density and counts are different measures. Generator and detector configurations keep separate profiles. The report does not identify every Mistral or detector API snapshot.
Lower density means fewer hallucination spans per 100 response words. Counts are hallucinating responses and spans, not total requests. Llama-2-70B-chat uses TheBloke’s 4-bit AWQ checkpoint.

Lineage
The sequence follows explicit supersedes links. Each score is estimated for that model; a relative can inform a sparse estimate but never sets a floor, so a newer release can score below an earlier one. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

How to read this profile
The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
The original benchmark tables show this evaluated configuration’s published results. Training choices, prompts, response splits, and metrics remain attached to each table. The profile stays outside general model rankings.
Llama-2-7B-chat (RAGTruth generator) is a research system model. No explicit reasoning mode is documented in this profile.
Evaluated system: Llama-2-7B-chat (RAGTruth generator). The linked benchmark-owner report supplies the full numeric results and protocol. This profile represents that evaluated configuration; it does not transfer results to a base model or another prompt. Context limit, current API tariff, and release date are not established by this evaluation.
The original benchmark results appear in the source tables above; they remain separate from weighted benchmark slots.
Last updated October 1, 2026. Runtime fields remain blank until a sourced snapshot exists.
Questions
How does Llama-2-7B-chat (RAGTruth generator) perform overall in AI benchmarks?
This configuration has original benchmark results in the source tables on this profile. Every published metric retains its evaluated configuration, source precision, and protocol. These results stay outside general model rankings; they do not produce a public overall score or transfer to a base model with different settings.
Does Llama-2-7B-chat (RAGTruth generator) have full benchmark coverage on BenchLM?
This configuration has results in the original benchmark tables on this profile. Those tables preserve every imported source metric, but they do not fill the site’s general scoring slots. Other benchmarks remain unmeasured, and compatible configurations are required before comparing results across different reports.
What is the context window size of Llama-2-7B-chat (RAGTruth generator)?
Llama-2-7B-chat (RAGTruth generator)'s context window is not documented in a source tied to this exact model yet. The profile leaves the value unavailable instead of borrowing a limit from an earlier family member or an unverified route. Maximum output length remains a separate field.
