Qdrant
Pros
- + Filtered ANN is the real differentiator: filters participate in the HNSW traversal, and in my testing recall under mandatory metadata filters stayed high where post-filter approaches collapsed.
- + Apache-2.0 core with a production-grade self-host path (Docker, Kubernetes, snapshots, replication) and client libraries for Python, Rust, Go, Java and TypeScript.
- + Free cloud tier is usable — 0.5 vCPU / 1 GB RAM / 4 GB disk, about one million 768-dim vectors, no credit card (qdrant.tech/cloud, at time of writing).
- + Quantization options (scalar, product, binary, asymmetric since 1.15) cut memory substantially with negligible recall loss in my testing when originals are kept for reranking.
- + Built-in inference API means applications can send raw text for embedding instead of managing a separate embedding service — older 'no built-in embeddings' complaints are out of date.
Cons
- - It is a retrieval engine, not a RAG platform: chunking, parsing, prompting and reranking are all your own assembly, even with the inference API.
- - Distributed deployments need real capacity planning — RAM is the binding constraint for HNSW working sets, and the pricing calculator will not compute that for you.
- - Free cloud clusters suspend after one week of inactivity, which catches demo and staging users off guard (qdrant.tech/cloud).
- - Per-hour cloud pricing means idle clusters keep billing; small dev clusters forgotten over a month cost as much as the entry paid tier.
- - Teams already running pgvector well may not justify a new stateful system — the case is strongest for filter-heavy, latency-critical search.
ChatGPT
Pros
- + Broadest multimodal surface in the category: text, reasoning, images, voice, video and agents in one subscription
- + Plus at $20/month is still the value anchor — my mixed weekly workload ran without visible caps
- + Deep research produced a 12-source competitive scan in about 8 minutes (two citation fixes needed, structure worth keeping)
- + GPT/connector ecosystem covers odd-shaped needs that no competitor matches
- + Business seat-type mixing (Standard + one Premium) is a sensible team pricing pattern
Cons
- - Free, Go, Plus and Pro conversations train models unless you opt out; no SOC 2 or SSO below Business
- - Caps downgrade silently to weaker models — quality drops without a warning
- - Ads now run on Free and Go in the US, including on a paid tier (Go)
- - Pro ladder ($100/$200/$500) buys capacity, not capability, with no annual discount anywhere in the lineup
- - Editing temperament drifts to confident verbosity; citations overreached sources in my deep research run
