Release 2026.11.05

API changes​

Up to 8 images per request​

Chat models now read up to 8 images per request, counted over the whole conversation, on POST /v1/chat/completions and POST /v1/responses. The limit depends on the model: 8 on orion-pro, 8 on orion-plus, 8 on qwen3.8-27b, 8 on qwen3.6-35b-a3b and 1 on paddleocr-vl-1.6. GET /v1/models publishes each model's limit as supported_inputs.references.max of its image input modality. See Image input.

An error code for too many images​

A request with more images than the model reads is still refused with HTTP 400 and the same message, but its code is now too_many_images instead of invalid_request_error, on POST /v1/chat/completions and POST /v1/responses. Images are counted over the whole conversation, earlier turns included.

In a long conversation, send only the most recent images, up to the model's limit, and replace the older ones with a short text. See Errors and rate limits.

Models​

No quantization or tokenizer on the Orion ids​

In GET /v1/models, the orion-pro and orion-plus entries no longer carry quantization or tokenizer. Both fields are optional in the provider schema. qwen3.8-27b, qwen3.6-35b-a3b and paddleocr-vl-1.6 keep them. See List models.

Documentation​

OpenCode​

The new Coding agents guide configures OpenCode with orion-pro and orion-plus on chat completions. OpenCode does not ask for reasoning by default, so the guide sets reasoningEffort on each model; any value other than none turns reasoning on. Codex CLI keeps its configuration in the Responses API guide.
