Be a part of us as we reveal how MLflow Tracing and the Mosaic AI Agent Framework present observability and automatic analysis as we iteratively enhance the factuality and accuracy of a GenAI software with DSPy. MLflow’s Tracing characteristic captures detailed details about LLM and agent inputs and outputs, permitting builders to simply establish the supply of bugs and surprising behaviors. Moreover, the Mosaic AI Agent Framework, a part of the Databricks Information Intelligence Platform, supplies capabilities for bettering the standard of GenAI purposes by way of human suggestions and automatic analysis.

On this work, we evaluate the effectiveness of sparse upcycling in opposition to continued pretraining (CPT) throughout totally different mannequin sizes, compute budgets, and pretraining durations. Our experiments present that sparse upcycling can obtain higher high quality, with enhancements of over 20% relative to CPT in sure situations. Nonetheless, this comes with a major inference price, resulting in 40% slowdowns in high-demand inference settings for bigger fashions. Our findings spotlight the trade-off between mannequin high quality and inference effectivity, providing insights for practitioners looking for to stability mannequin high quality and deployment constraints.
This paper presents a complete examine of the impression of elevated context size on RAG efficiency throughout 20 widespread open supply and business LLMs. We run RAG workflows whereas various the whole context size from 2,000 to 128,000 tokens (and a pair of million tokens when potential) on three domain-specific datasets, and report key insights on the advantages and limitations of lengthy context in RAG purposes. Our findings reveal that whereas retrieving extra paperwork can enhance efficiency, solely a handful of the latest state-of-the-art LLMs can keep constant accuracy at lengthy context above 64k tokens. We additionally establish distinct failure modes in lengthy context situations, suggesting areas for future analysis.
On this work, we discover the usage of MixAttention, a mannequin structure modification that mixes sliding window consideration, the place solely a small subset of latest tokens is saved within the KV cache, with KV cache sharing throughout layers. Our experiments reveal that MixAttention considerably reduces reminiscence utilization and improves inference pace with out sacrificing mannequin efficiency in each quick and long-context duties. We additionally discover numerous configurations of this structure, figuring out people who keep high quality throughout analysis metrics whereas optimizing useful resource effectivity.
We introduce Critique-out-Loud (CLoud) RLHF reward fashions that cause explicitly in regards to the high quality of a response from an LLM assistant. CLoud reward fashions function by first producing a pure language critique of the assistant’s response that’s then used to foretell a scalar reward for the standard of the response. We reveal the success of CLoud reward fashions for each Llama-3-8B and 70B base fashions: in comparison with basic reward fashions, CLoud reward fashions enhance pairwise desire classification accuracy on RewardBench by 4.65 and 5.84 share factors for the 8B and 70B base fashions respectively. Moreover, CLoud reward fashions result in a Pareto enchancment for win charge on ArenaHard when used because the scoring mannequin for Finest-of-N. Lastly, we discover the best way to exploit the dynamic inference compute capabilities of CLoud reward fashions by performing self-consistency decoding for reward prediction.
