DeepInfra raises $107M Series B to scale the inference cloud — read the announcement

Fine-Tuning vs RAG vs Prompting: 2026 GuidePublished on 2026.08.06 by DeepInfraFine-Tuning vs RAG vs Prompting: 2026 Guide

When an AI system yields unreliable answers, the root cause could be an unclear system prompt, missing context, poor retrieval quality, or simply using the wrong base model. Teams end up spending weeks experimenting with prompt changes, retrieval-augmented generation (RAG), or fine-tuning to improve response quality. But before deciding which technique to adopt, it is […]

Best Open-Source Multimodal AI Models for Production (2026)Published on 2026.08.05 by DeepInfraBest Open-Source Multimodal AI Models for Production (2026)

Open-source multimodal models have a benchmark problem. Every new release comes with DocVQA and MMMU scores, but those numbers rarely reflect how a model performs on a real workload. A model can lead the leaderboard and still struggle with a scanned invoice, a noisy image, or a multi-step agent workflow. Real-world data is far less […]

Introducing Prompt Cache Retention: Keep Your Context Warm for 5 Minutes or an HourPublished on 2026.08.05 by DeepInfraIntroducing Prompt Cache Retention: Keep Your Context Warm for 5 Minutes or an Hour

Retain a prompt's KV cache for 5 minutes or an hour — reuse skips prefill for a faster time to first token and bills at the discounted cache-read rate. One field on the request.

vLLM vs SGLang: Performance, Features & Deployment ComparedPublished on 2026.08.04 by DeepInfravLLM vs SGLang: Performance, Features & Deployment Compared

Somebody on your team read a benchmark post, and now there’s a ticket to migrate the inference stack. That’s how most vLLM vs SGLang decisions start. A published test reports a 29 percent throughput gap, the number lands in Slack, and two weeks later you’re debugging kernel version conflicts at midnight while p99 latency sits […]

GLM 5.2 vs Claude Opus 4.8: Pricing the Task, Not the TokenPublished on 2026.08.03 by DeepInfraGLM 5.2 vs Claude Opus 4.8: Pricing the Task, Not the Token

Every GLM 5.2 vs Claude Opus 4.8 comparison lands in the same place. Opus wins most coding benchmarks, GLM costs a fraction as much, pick according to your budget. That framing takes the price cards at face value, but it’s misleading. Price a finished unit of work instead of a million tokens and the gap […]
