Ekrem Sarı
Ekrem is an AI Researcher and Data Analyst at AIMultiple. He designs and runs hands-on benchmarks for AI and LLM systems.
Professional Experience
At AIMultiple, Ekrem benchmarks end-to-end AI systems and builds the data workflows and dashboards used to track benchmark and product metrics. His benchmarks cover embedding and reranker models, vector and graph databases, inference engines, quantization, GPU concurrency and multi-GPU scaling, cloud GPU pricing and providers, text-to-SQL, and RAG and agentic RAG frameworks.
Before AIMultiple, he worked as an Assessor at Yandex, where he evaluated search quality and labeled large volumes of data against detailed guidelines to support ranking and model quality.
Research Interest
Ekrem's work focuses on the MLOps and LLMOps lifecycle and on measuring the performance of AI systems. He compares models, frameworks, and infrastructure on metrics such as accuracy, throughput, API cost, and scalability, across the stack from embedding models and vector databases to GPU and cloud infrastructure. His MSc thesis automates systematic literature reviews with a RAG-based pipeline.
Education
Ekrem holds a BA from Hacettepe University and is completing an MSc at Başkent University.

Email Archiving Software Benchmark
We provisioned a Microsoft 365 tenant, populated it with a 10,000-mail synthetic corpus and 1,700 attachments across 8 file-type subtypes, then benchmarked NinjaOne SaaS Archiver, Barracuda Cloud Archiving Service, Acronis Cyber Protect Cloud Email Archiving, and MailPiler on the same tenant against 10 dimensions covering ingestion, search, attachment recall, export, immutability, legal hold, audit, encryption,…
Disaster Recovery Benchmark: Acronis vs Comet vs MSP360
We benchmarked Acronis Cyber Protect Cloud, Comet Backup, and MSP360 Managed Backup on disaster recovery. Each vendor imaged a live Windows Server 2022 and a live Ubuntu 24.04 server carrying the same deterministic workload, a web service, a 10,000-row database, and 50 files, then recovered the whole machine onto a separate server after a ransomware-style…
Graph Database Benchmark: Neo4j vs FalkorDB vs Memgraph
We benchmarked Neo4j, FalkorDB, and Memgraph on a synthetic graph derived from 120,000 Amazon product reviews (381K nodes, 804K edges). We ran 12 query templates with 1,000 measurements each, tested ingestion at 6 batch sizes, sustained concurrent load for 60 seconds at up to 32 threads, and measured memory, cold start, mixed workload, and index…
Agentic RAG Benchmark: Multi-Database Routing Across 36 LLMs
We benchmarked 36 large language models on cross-database routing. Each model receives a natural language question and 11 SQL databases described at paragraph level, then has to decide which database holds the answer before it writes any SQL. The 11 databases were drawn from 80 BIRD-SQL candidates by clustering their description embeddings, so the candidates…
Top 70+ Cloud GPU Providers in 2026
Cloud GPU providers fall into three tiers. Hyperscalers run broad cloud platforms with GPU rental as one product among many. Specialist neoclouds focus on GPU and AI infrastructure as their core product. Community marketplaces aggregate inventory from many small operators, often at the floor of the published price spread. Pick a GPU model and a…
RAG Frameworks: LangChain vs LangGraph vs LlamaIndex
We benchmarked 5 RAG frameworks: LangChain, LangGraph, LlamaIndex, Haystack, and DSPy, by building the same agentic RAG workflow with standardized components: identical models (GPT-4.1-mini), embeddings (BGE-small), retriever (Qdrant), and tools (Tavily web search). This isolates each framework’s true overhead and token efficiency. The benchmark consisted of 100 queries, with each framework running the full set…
Backup software benchmark: Acronis vs NinjaOne vs Comet vs MSP360
We benchmarked NinjaOne Backup, Acronis Cyber Protect Cloud Backup, Comet Backup, and MSP360 Managed Backup on identical AWS infrastructure. Each vendor ran a file-mode backup of the same 625,946-file / 50 GB workload and a full image backup of the system disk, then restored the 15 GB medium subdirectory. Here are the four backup products…
Compare Relational Foundation Models
We benchmarked SAP-RPT-1-OSS against gradient boosting (LightGBM, CatBoost) on 17 tabular datasets spanning the semantic-numeral spectrum, small/high-semantic tables, mixed business datasets, and large low-semantic numerical datasets. Our goal is to measure where a relational LLM’s pretrained semantic priors may provide advantages over traditional tree models and where they face challenges under scale or low-semantic structure.…
DLP Software Benchmark
We benchmarked Acronis DeviceLock DLP and ManageEngine DLP Plus on identical Windows Server 2022 VMs with 28 scenarios: 23 data leak tests (including 12 adversarial evasion files), 3 agent security tests, and 2 tests under high CPU and memory consumption. For the other DLP products, Netwrix Endpoint Protector, Sophos Intercept X, Teramind DLP, and Trellix…
Reranker Benchmark: Top 8 Models Compared
We benchmarked 8 reranker models on ~145k English Amazon reviews to measure how much a reranking stage improves dense retrieval. We retrieved top-100 candidates with multilingual-e5-base, reranked them with each model, and evaluated the top-10 results against 300 queries, each referencing concrete details from its source review. The best reranker lifted Hit@1 from 62.67% to…
