      maxOutput: 16000
      streaming: true
      reasoning: true
      vision: true
      tools: true
      jsonOutput: true

Files touched

• packages/models/src/models/zai.ts
  • Updated glm-4.6v pricing
  • Added new glm-4.6v-flashx model entry with detailed capabilities

Test plan

• Build project to ensure type integrity after changes
• Verify glm-4.6v pricing updates are reflected in the model list
• Verify new glm-4.6v-flashx model appears with correct properties (input/cached/input, output, contextSize, maxOutput, features)
• Run existing unit tests (if any) to confirm no regressions

Notes

• The new glm-4.6v-flashx model provides extended features (streaming, reasoning, vision, tools, jsonOutput) for advanced workflows. Reviewers can adjust pricing or capabilities if product requirements change.

298-299: LGTM! Pricing updates match PR objectives.

The pricing reductions for glm-4.6v are correctly implemented and align with the documented changes.

---

313-338: Configuration is accurate and matches official Z.ai documentation.

The glm-4.6v-flashx model pricing and capabilities have been verified against official Z.ai specifications:

• Pricing: inputPrice ($0.04/1M), outputPrice ($0.40/1M), and cachedInputPrice ($0.004/1M) match the official documentation exactly.
• Capabilities: streaming, vision, tools, and reasoning are all confirmed in official API documentation.
• Context & output: 128K context window and conservative maxOutput of 16000 tokens are appropriate for this variant.

The configuration is correct and ready.

⚠️ Potential issue | 🟡 Minor

Date mismatch with PR objectives.

The code specifies 2025-12-08 for both releasedAt and publishedAt, but the PR objectives document states these should be 2025-06-01. While the commit message indicates the dates were intentionally updated, this creates an inconsistency with the documented PR objectives.

Please clarify which date is correct, as this metadata may affect model display ordering or filtering.

🤖 Prompt for AI Agents

In packages/models/src/models/zai.ts around lines 318-319, the releasedAt and
publishedAt fields are set to 2025-12-08 but the PR objectives require
2025-06-01; update both fields to new Date("2025-06-01") so the metadata matches
the PR objectives (or, if the December date is intentional, update the PR
objectives/docs to reflect 2025-12-08 and note the reason).
