Reposted by RedisCassidy @cassidoo.co · 09/07/2026This week's sponsor is @redis.io! Ever notice your agents just...forget everything the second a session ends? Redis Agent Memory fixes that. It gives your agents short-term memory plus context that actually sticks around across conversations, managed for you. redis.io/agent-memory...redis.ioRedis Agent Memory | RedisDevelopers love Redis. Unlock the full potential of the Redis database with Redis Enterprise and start building blazing fast apps. 021
Redis @redis.io · 05/06/2026➡️ How Redis Data Integration keeps agent context fresh from your source databases without manual stitching ➡️ The cold-cache vs. warm-cache latency difference, measured live. If you're building agents, or agent infrastructure, watch this today. 000
Redis @redis.io · 05/06/2026➡️ Working memory vs. long-term memory, and when an agent should write to each ➡️ How Redis Context Retriever (the tool at the heart of Redis Iris) auto-generates business entities and exposes them as MCP tools ➡️ Why semantic caching with LangCache turns paraphrased repeat queries into cache hits 100

Redis @redis.io · 02/06/2026Streams get NACKing. The new XNACK command lets consumers explicitly release pending messages, so they're immediately re-delivered to other consumers instead of sitting idle in the PEL. SILENT, FAIL, and FATAL modes map to real-world failure scenarios. 100
Redis @redis.io · 02/06/2026Rate limiting is one of the most common Redis patterns, and it used to need Lua. Not anymore. The new INCREX command gives you a window counter rate limiter natively, with bounds and expiration control built in. 100

Redis @redis.io · 20/01/2026Their secret? Treating cache as a first-class part of the data system, not an afterthought. By integrating Redis directly into the write path, Uber tackled one of the hardest problems in distributed systems: cache invalidation at massive scale. 100

Redis @redis.io · 01/12/2025In this course, you'll learn how to build a semantic cache that reuses responses based on meaning, not exact text matches, as well as: • Measure cache performance • Enhance accuracy with cross-encoders & LLM validation • Build caching into an AI agent that's faster + more cost-effective over time 110
Redis @redis.io · 01/12/2025AI agents often make redundant API calls for questions that mean the same thing. Semantic caching helps your agents recognize when different queries share the same meaning, reducing costs and speeding up responses. 100
Redis @redis.io · 01/12/2025We worked with @deeplearningai.bsky.social to create a new course called "Semantic Caching for AI Agents."

Reposted by RedisRaphael De Lio @raphaeldelio.dev · 21/07/2025🧵 1/ LLMs are stateless. They don’t remember past interactions. Every prompt is treated as an isolated request.
