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.

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. Column definitions: Ranking: Subscribers are linked…

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…

LLM VRAM Calculator for Self-Hosting

Self-hosting an LLM means running inference on hardware the operator controls rather than via a third-party API, which changes the cost, data control, and privacy profile. Whether a model runs at all depends on memory. The calculator estimates the VRAM or unified memory a model needs to run locally, based on the model, its precision,…

Multi-GPU Benchmark: B200 vs H200 vs H100 vs MI300X

For over two decades, optimizing compute performance has been a cornerstone of my work. We benchmarked NVIDIA’s B200, H200, H100, and AMD’s MI300X to assess how well they scale for Large Language Model (LLM) inference. Using the vLLM framework with the meta-llama/Llama-3.1-8B-Instruct model, we ran tests on 1, 2, 4, and 8 GPUs. We analyzed…

GPU Concurrency Benchmark: H100 vs H200 vs B200 vs MI300X

I have spent the last 20 years focusing on system-level computational performance optimization. We benchmarked the latest NVIDIA GPUs, including the NVIDIA’s H100, H200, and B200, and AMD’s MI300X, for concurrency scaling analysis. Using the vLLM framework with the gpt-oss-20b model, we tested how these GPUs handle concurrent requests, from 1 to 512. By measuring…

Video Search API Benchmark: Bright Data vs YouTube

We compared Bright Data Video Search with YouTube search on 50 English queries across five query types. 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 with…

DGX Spark alternatives: RTX, Ryzen AI Halo and Mac Studio

We compare published DGX Spark, RTX and Ryzen AI Halo inference benchmarks, covering prompt processing, token generation and longer contexts. Alternatives include Framework Desktop, Mac Studio and GB10 systems from other manufacturers. Decode speed measures output tokens generated per second. Higher values mean faster response generation. All six results use GPT-OSS 20B MXFP4 in Ollama…

Free Cloud GPUs: Models, Limits and Access Requirements

Free cloud GPUs are available through Python notebooks, AI demos and monthly compute credits. Compare GPU hardware, free allowances and access requirements, or check which services suit your workload. Two T4s provide two separate 16 GB memory allocations. Running a model across both requires software that distributes the workload. The combined capacity does not make…

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.…

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…
