Amazon Bedrock
Pros
- + Widest model catalogue I track: Anthropic, Meta, Mistral, Nova, Gemma, MiniMax, Moonshot, GLM, Grok and OpenAI variants behind one API
- + Flex tier at 50% off standard and batch inference at 50% off let me halve a summarisation bill without changing models
- + Standard/Priority/Flex tiering is a bigger cost lever than model choice in the workloads I costed
- + Guardrails blocked the obvious injection and harmful-content probes in my red-team pass
- + Inherits IAM, VPC endpoints, KMS and AWS compliance scope, so security review is a conversation about configuration, not a new vendor
Cons
- - Pricing is a provider-by-region-by-tier matrix; Nova Micro alone ranges $0.035 to $0.040 input across regions and GLM 5 $1.00 to $1.55
- - No free tier documented on the pricing page — experiments bill from the first token
- - Guardrails missed a subtle document-embedded instruction attempt in my testing; they are a filter, not a policy engine
- - AgentCore-style services meter by hour and operation, so idle agents with warm state accrue cost (corroborated by an AWS Builder Center analysis)
- - Regional model availability is uneven; several newer model families serve only a few regions
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
