Updated model

Both anthropic and OpenAI provide updated model than can be used by their apis, but BoltAI mobile doesn’t seem to recognize newer models and keep on proposing the old ones. Now for example Gtp-5 is not available in boltai mobile that propose the use of several models that OpenAI deprecates. What is happening when I use one of those models? Which llm model is really used on OpenAI side? Why the boltai platform doesn’t automatically align to newer models? Thanks. Paoll
