Anthropic has a waitlist for their Claude API, no clue if they're letting people in yet though. Otherwise, OpenAI is basically the only game in town. You can use an abstraction layer like langchain to make it easier to switch later. I expect that in the next couple years, basically everybody who owns a GPU farm (Google, Amazon, other cloud hosting companies, etc) will be offering LLM APIs.

r/MachineLearning on Reddit: [D] Is there currently anything comparable to the OpenAI API?
January 12, 2023 -
I am a designer and a small frontend developer. The OpenAI API makes it extremely easy for me to build AI functionality into apps, although I only have a very basic understanding of AI. Though of course I can't make any deep changes, I am even able to fine tune models and adapt them for my intended use.
Now I was wondering if there is anything comparable on the market at the moment. I know of Meta's LLaMA, but you can only use it locally, which makes it harder to easily implement into applications. Also, you are not allowed to use it for commercial purposes.
I haven't found much from Google or other tech companies. Does OpenAI have a monopoly here or are there alternatives worth mentioning that could be used?

From what I've heard, Google has a habit of just randomly ending APIs that people have built their business around.

Best Alternative to OpenAI API? - API - OpenAI Developer Community
March 4, 2024 - Hi everyone! I am building an AI startup which has a very high velocity of generated messages per minute (upwards of 1000 messages per minute). They are ~2000 tokens per input. Anyways, given that background, as we all know OpenAI’s API is not able to handle this output volume and has much more downtown than we’d like so see for a LLM provider over the past few months.
