Seed-oss-36b reasoning format not supported

[whoisjeremylam]

Description

What would be the best way to support Seed's reasoning tags?

Snippet from my config.json (provider is a locally vllm server)

        "Seed-OSS-36B-Instruct": {
          "name": "Seed-OSS-36B-Instruct",
          "context_window": 262144,
          "reasoning": true,
          "tool_call": true,
          "limit": {
            "context": 262144,
            "output": 81920
          }
        }

From the official chat template (https://huggingface.co/ByteDance-Seed/Seed-OSS-36B-Instruct/blob/main/chat_template.jinja):

{%- set think_begin_token      = '<seed:think>'             -%}
{%- set think_end_token        = '</seed:think>'            -%}

I think vercel ai sdk has an option for this, we need to integrate that or something

I was reading the model card and Seed also has a thinking_budget that is a numerical value of tokens to use for reasoning.
