TiDB Vector Search for RAG: When to Skip the Second DB
TiDB vector search earns its keep in one specific scenario: when a query needs to filter on live, frequently-changing relational data and rank by vector similarity in the same transaction. If that’s your actual access pattern, and it is for most multi-tenant RAG and agent memory systems, storing embeddings in TiDB alongside the data they […]
What Is TiDB? Distributed SQL and When It’s Worth It
TiDB is a MySQL-compatible distributed SQL database that separates compute from storage and uses Raft consensus to give you horizontal write scaling and strong consistency without building and maintaining your own sharding layer. That’s the direct answer. What most introductions lead with instead, the HTAP story of running transactions and analytics on the same live […]
Claude 5.5 on Amazon Bedrock: The Real Lifecycle Checklist
Choosing to call Claude 5.5 through Amazon Bedrock rather than Anthropic’s first-party API is as much a lifecycle decision as a model-selection decision, and most teams treat it as the latter only. Bedrock runs its own retirement calendar, independent of Anthropic’s, and it is typically longer. The policy governing that calendar also just changed for […]
DeepSeek V4.1 Flash Migration: What’s Already Changed Under You
If you’re still calling deepseek-v4-flash in production, you have very likely already migrated to DeepSeek V4.1 Flash without doing anything, because DeepSeek retired the old V4 Flash model and silently rerouted that legacy name to V4.1 Flash at the same price. Then, five weeks later, DeepSeek updated V4.1 Flash itself to a new retrained checkpoint, […]
GPT-6.1 Sol vs GPT-6 Astra: Choosing a Model for Production
Default to GPT-6.1 Sol for most production workloads, escalate to GPT-6 Astra only for the specific tasks where a stronger first attempt is worth roughly five times the cost, and push high-volume, simple tasks down to GPT-6 Luna. That’s the straightforward price-performance answer. The less obvious and more consequential issue for any team upgrading from […]
Gemini 4.0 Pro: Production Readiness Before It’s Even GA
There is no generally available model called Gemini 4.0 Pro today, and that fact should shape your production readiness plan more than any leaked benchmark. What Google has actually shipped is Gemini 4 Argon, announced on September 30, 2026, a frontier model in a staged, restricted rollout through the Fairwind Program, currently limited to vetted […]
