- Fix an error message in getting image bytes from a URL in Gemini.
- Remove safety settings from the Gemini OpenAI request and set all harm categories to block only high.
- Add a log statement about how many images are sent to Gemini vision.
- Add support for getting base64-encoded images via openAI's image_url.
- Add `context` as a parameter for the function `LogError`.
- Handle the error from `image.GetImageFromUrl` by logging it.
- Convert the role to `user` if it is `system` and add a dummy model message to make Gemini happy.
* fix: openai response should contains `model`
- Update model attributes in `claudeHandler` for `relay-claude.go`
- Implement model type for fullTextResponse in `relay-gemini.go`
- Add new `Model` field to `OpenAITextResponse` struct in `relay.go`
* chore: set model name response for models

* Update relay-ali.go: 改进stream模式，添加联网搜索能力
通义千问支持stream的增量模式，不需要每次去掉上次的前缀；实测qwen-max联网模式效果不错，添加了联网模式。如果别的模型有问题可以改为单独给qwen-max开放
* 删除"stream参数"
刚发现原来阿里api没有这个参数，上次误加了。
* refactor: only enable search when specified
* fix: remove custom suffix when get model ratio
