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.

Top 60+ 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. We track 67 cloud GPU providers…

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…

Open Source Embedding Models Benchmark for RAG

We benchmarked 14 open-source embedding models, self-hosted on a single H100, across 500+ manually curated retrieval queries spanning legal contracts, customer support tech notes, and medical abstracts. NVIDIA Llama-Embed-Nemotron-8B leads in accuracy. On cost, Google’s EmbeddingGemma-300m runs roughly 4x cheaper than Nemotron at the cost of a small accuracy loss. Open source embedding models benchmark…

Comparison of Top 6 Free Cloud GPU Services

The best free GPU tier is worth about $19 a month at rental rates, and eight platforms give a real GPU with no credit card. Six of them cap free usage by the month, and we priced those at the cheapest current on-demand rate for each GPU in our cloud GPU pricing data. Each bar…

Backup software benchmark: Acronis vs NinjaOne vs Comet vs MSP360

We benchmarked Acronis Cyber Protect Cloud Backup, Comet Backup, MSP360 Managed Backup, and NinjaOne 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. Backup software benchmark results Here are…

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.…

Benchmark of 40+ LLMs in Finance: Claude Fable 5 & GPT-5

We evaluated 40+ LLMs in finance on 238 hard questions from the FinanceReasoning benchmark to identify which models excel at complex financial reasoning tasks like statement analysis, forecasting, and ratio calculations. LLM finance benchmark overview We evaluated LLMs on 238 hard questions from the FinanceReasoning benchmark (Tang et al.).62 This subset targets the most challenging…

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,…

Top Serverless Functions: Vercel vs Azure vs AWS

Serverless functions enable developers to run code without having to manage a server. This allows them to focus on writing and deploying applications while infrastructure scaling and maintenance are handled automatically in the background. In this benchmark, we evaluated 7 popular cloud service providers following our methodology to test their serverless function performance. We measured…

Multimodal Embedding Models: Apple vs Meta vs OpenAI

Multimodal embedding models excel at identifying objects but struggle with relationships. Current models struggle to distinguish “phone on a map” from “map on a phone.” We benchmarked 7 leading models across MS-COCO and Winoground to measure this specific limitation. To ensure a fair comparison, we evaluated every model under identical conditions using NVIDIA A40 hardware…
