Pricing
PaidThe OpenAI API uses pay-as-you-go, per-token pricing that varies by model. GPT-5.6 Sol, built for complex reasoning and coding, costs $5.00 per 1M input tokens and $30.00 per 1M output tokens with a 1.05M context length. GPT-5.6 Terra, balancing intelligence and cost, costs $2.00 per 1M input tokens and $12.00 per 1M output tokens. GPT-5.6 Luna, designed for cost-sensitive, high-volume workloads, costs $0.20 per 1M input tokens and $1.20 per 1M output tokens. All three share a 1.05M context length and 128K max output tokens. Additional costs apply for fine-tuning, evals, and specialized tools like web search or file search depending on usage. New accounts must add billing details before making live API calls, and there is no free-tier token quota; enterprise organizations can contact sales for custom pricing, dedicated support, and advanced data residency and retention controls.
PaidAmazon Bedrock uses consumption-based pricing with no upfront commitment for on-demand use. Foundation model inference is billed per 1M input/output tokens, with rates varying by provider and model — from lightweight models like Amazon Nova Micro or Meta Llama 3 8B at a fraction of a cent per 1,000 tokens, to frontier models like Claude and GPT-5.6 ranging from $0.22 to $13.75 per 1M input tokens and $1.32 to $82.50 per 1M output tokens depending on context window.
Batch inference offers roughly 50% savings over on-demand pricing for select models, and a Flex tier offers similar discounts with relaxed latency requirements, while a Priority tier costs about 75% more for guaranteed low latency. Provisioned Throughput pricing (hourly, with 1- or 6-month commitment discounts) suits teams needing dedicated, guaranteed capacity rather than variable on-demand access.
Additional Bedrock features are billed separately: Guardrails charge per 1,000 text units (~$0.07–$0.17), Knowledge Bases charge for index storage ($5/GB/month) plus per-1,000-query retrieval fees, Model Evaluation charges standard token rates plus $0.21 per human evaluation task, and Custom Model Import is billed per unit-minute plus storage. AWS offers up to $200 in free credits for new customers.

Summary
Developer platform for GPT models, AI agents, and real-time voice
The fully managed AWS platform for building generative AI applications and agents at production scale
OpenAI API Pros & Cons
Pros
- Access to frontier GPT-5.6 models spanning a full range of intelligence and cost tiers
- Comprehensive platform covering text, agents, voice, and multimodal use cases in one place
- Agents SDK and built-in tools simplify building production-grade autonomous agents
- Strong enterprise security posture, including SOC 2 Type 2 and HIPAA BAAs
- No training on API business data by default, with zero data retention available by request
- Extensive documentation, cookbook examples, and an active developer community
Cons
- Pay-as-you-go token costs can scale quickly for high-volume or long-context applications
- New accounts must add billing details before making API calls, with no ongoing free-tier quota
- Frontier reasoning models like GPT-5.6 Sol carry premium per-token pricing versus smaller models
- Enterprise features like dedicated support and advanced data residency require contacting sales
- Rate limits and model access can vary by usage tier, requiring spend history to unlock higher limits
Amazon Bedrock Pros & Cons
Pros
- Access to models from nearly every major AI lab through one consistent API and billing relationship
- No infrastructure to provision or manage, with automatic scaling built into the serverless architecture
- Strong compliance posture out of the box, useful for regulated industries like finance and healthcare
- Pay-per-use pricing means no cost for idle capacity on on-demand inference
- AgentCore and Knowledge Bases reduce the engineering lift of building production RAG and agent systems
- Deep integration with the broader AWS ecosystem for teams already building on AWS
Cons
- Usage-based pricing across dozens of models and add-on features makes cost estimation genuinely complex
- Best suited to teams already inside the AWS ecosystem; using it standalone adds a real AWS learning curve
- Some frontier models arrive on Bedrock later than on their original provider's own API
- Provisioned Throughput commitments can be expensive relative to smaller-scale on-demand usage
- Guardrails, Knowledge Bases, and Evaluation are billed as separate line items, which can obscure total spend
