DeepSeek adds vision to its cheap agent model and ships a free Files API
DeepSeek launched V4-Flash-Vision-Exp with image input, 1M context, JSON output, tool calls, Responses API and an Anthropic-compatible endpoint. Images cost roughly $0.17 per 1,000 at the published tokenization, while peak/off-peak pricing remains in place.
The free Files API lets you upload once and reference an image by file_id across requests. Harness 0.1.1 added support immediately.
WHY IT MATTERS
Screenshot-reading, chart parsing and self-correcting agent loops stop being a separate budget line when vision rides on the same inexpensive model.
