Ekrem Sarı
Ekrem is an AI Researcher and Data Scientist 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 a Data Scientist at Yandex, where he queried and analyzed large datasets with SQL to evaluate search and ranking quality against detailed guidelines.
Research Interest
Ekrem's work focuses on measuring how LLM and retrieval systems perform in practice. He designs the test harness, runs the workloads on real hardware, and compares models, frameworks, and infrastructure on accuracy, throughput, latency, cost, and scalability, across the stack from embedding models and vector databases to inference engines and GPU infrastructure. His MSc thesis automates systematic literature reviews with a RAG-based pipeline.
Education
Ekrem holds an MSc in Management Information Systems from Başkent University, where his thesis automated systematic literature reviews with a RAG-based pipeline, and is pursuing a second MSc in Data and Knowledge Engineering at Hacettepe University.

Remote Browsers: Web Infra for AI Agents Compared
AI agents rely on remote browsers to automate web tasks without being blocked by anti-scraping measures. The performance of this browser infrastructure is critical to an agent’s success. We benchmarked 8 providers on success rate, speed, and features. To do this, we executed 160 automated tasks, running 4 distinct scenarios 5 times for each service…
Video Search API Benchmark: Bright Data vs YouTube
We compared Bright Data Video Search with YouTube search on 50 English queries across five types of queries. Both engines were queried to exhaustion, and a three-model panel assessed sampled video frames. Usable clips per search estimates how many returned videos contain the queried subject or action. It combines the number of unique videos returned…
Embedding Models: 25 Models Benchmarked for Retrieval
We benchmarked 25 embedding models on 200 retrieval questions across finance, legal contracts, technical support and medical literature. The four corpora contained 341,040 text passages in total. Each query searched its own domain. nDCG@10 measures how highly the recorded relevant passages appear in the first ten results. Scores range from 0 to 1, with higher…
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…
Large-Scale Web Scraping: 7 Providers Benchmarked
We ran two benchmarks against live websites, from 5 to 5,000 concurrent requests. The first sent 260,000 requests through four web unblockers across the Tranco top 10,000 domains, plus a markdown extraction test on 10,000 URLs. The second fetched 65,000 product and search pages from each of five scraping providers across 100 e-commerce domains. Metrics…
E-Commerce Scraper: 4 Providers Benchmarked
We benchmarked four web data providers across 100 e-commerce domains, fetching 65,000 product and search pages each at 5 to 5,000 concurrent requests. Averaged across concurrency levels, Bright Data reached the highest success rate (76%) at a 16-second median. Apify recorded the highest median response time at 46 seconds. Response time is reported as the…
Open Source Embedding Models: 11 Models Benchmarked for Retrieval
nDCG@10 scores the placement of recorded relevant passages within the first ten search results. A score of 1 represents the ideal ranking for the recorded positives. Passages nearer the top receive more weight. PPLX Embed v1 4B led the comparison at 0.741 nDCG@10, followed by PPLX Embed v1 0.6B at 0.698. Multilingual E5 Large ranked…
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…
Cloud GPU Rental Price Index
Last released has the largest price increase among the three groups. Its on-demand median rose from $2.12 per GPU-hour in October 2024 to $4.72 in September 2026. Over the same period, the Modern group moved from $1.35 to $1.45, while Legacy fell from $1.77 to $0.95. Each median uses the listings present that month. Providers,…
Top 70+ Cloud GPU Providers
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.
