feat: add Pareto Inference metered GLM 5.3 Flash API

[dylanduyvu]

Add Pareto Inference's prepaid, metered GLM 5.3 Flash API. This replaces #6138, which described the old Pareto Pass subscription. I work on Pareto Inference.

The entry adds one provider, its logo, and z-ai/glm-5.3-flash. Prices are USD per million tokens: $0.03 input, $0.10 output, and $0.006 cached input. It uses https://api.paretoinference.com/v1 with PARETO_API_KEY and the OpenAI-compatible adapter.

Sources and model settings

• Current pricing
• Public model catalog
• API reference
• Coding-agent setup
• Dashboard model information

The model inherits zhipuai/glm-5.3-flash, including its 1M context and 131,072-token output limit. The output ceiling is also documented in our API reference. Input modalities are narrowed to text, image, and video; PDF is not advertised. Pareto accepts reasoning_effort with low/high/max and returns reasoning in reasoning_content. It does not expose the lab's separate thinking toggle. These settings were checked against our current API contract and serving code; maximum-length and multimodal requests were not live-tested for this submission.

Validation

• bun validate passed on the current dev base and with this addition.
• Generated catalog checks passed for the sole model ID, endpoint, prices, limits, and input modalities.
• git diff --check passed.

The public model endpoint is a thin ID list, so this uses a hand-authored entry rather than a sync module. No results from the old subscription PR are presented as new tests here.

Hi @rekram1-node, I’m Dylan from Pareto Inference. This replaces our old Pass submission with the current metered GLM 5.3 Flash API. It adds three files, includes pricing and setup sources, and passes bun validate. Could you review it or let me know what else you need for inclusion? Happy to help test the integration.
