OpenAI GPT API
Use the OpenAI GPT models currently supported by FusionPointAI - GPT-5.5, GPT-5.4, GPT-5.4 mini, and GPT-5.4 nano - through a flat-rate API plan for production workloads.
Included in the plan
Supported GPT models
Use the GPT models currently listed in the FusionPointAI catalogue: GPT-5.5, GPT-5.4, GPT-5.4 mini, and GPT-5.4 nano.
Unlimited Tokens
No commercial token quotas or usage caps are applied by the FusionPointAI plan; model context, output, and upstream protection controls can still apply technically.
Production-ready latency
Managed infrastructure tuned for stable response times under sustained load.
Operational support
Get help with integration, issue handling, rollout planning, and day-to-day operations.

Security and operational fit
Credential-based access
Use issued service credentials for application access and keep them out of client-side code and public repositories.
OpenAI-compatible migration
Evaluate compatible GPT workloads through documented request patterns, updated credentials, and FusionPointAI endpoints before production rollout.
Support during rollout
Use support channels for implementation questions, issue diagnosis, and production rollout planning.
When FusionPointAI's OpenAI GPT API access is a good fit
This page is for teams that need supported GPT models in production with predictable commercial terms rather than variable token billing.
Recurring production traffic
Applications that call GPT models every day can plan around a fixed monthly subscription instead of metered usage spikes.
Predictable API expenditure
Finance, product, and engineering teams can forecast GPT API costs while still using the supported models listed on this page.
Review pricingOpenAI-compatible integration work
Teams with existing GPT request patterns can evaluate endpoint, authentication, and model identifier changes before moving traffic.
Read the API documentationWhen usage-based pricing may fit better
Very low usage, short experiments, or occasional development tests may cost less on a metered provider plan than on a fixed monthly subscription.
Migration and OpenAI-compatible access
FusionPointAI is not the official OpenAI endpoint. It provides OpenAI-compatible request patterns for the supported GPT models listed in the FusionPointAI catalogue.
Review model use
Map your current model identifiers to the supported GPT models published by FusionPointAI.
Update credentials and endpoint
Use FusionPointAI credentials and the documented base URL rather than official OpenAI credentials or endpoints.
Test before production
Validate prompts, responses, error handling, and traffic behaviour before moving production workloads.
Integration
Receive access
Order the service and receive your credentials and documentation for immediate setup.
Connect your applications
Use OpenAI-compatible request patterns to connect existing tools, products, and internal systems through FusionPointAI.
Run without usage caps
Increase throughput without planning around token quotas or per-request billing.
OpenAI GPT API questions
Which GPT models are supported?
The current OpenAI GPT catalogue on this page lists GPT-5.5, GPT-5.4, GPT-5.4 mini, and GPT-5.4 nano.
Does Unlimited mean no token quota?
Yes for the commercial plan: FusionPointAI does not apply token quotas or usage caps. Technical model limits, output limits, and temporary protection controls may still apply.
Is this the official OpenAI API?
No. Requests are made through FusionPointAI infrastructure using supported OpenAI-compatible patterns, not through the official OpenAI endpoint.
How are newer OpenAI releases handled?
Availability is based on the models explicitly listed by FusionPointAI; automatic inclusion of later provider releases is not promised.
