Summary

Alibaba's Qwen 3.5 model family is available on Fireworks serverless inference but missing from the catalog. The catalog has Qwen 3.6 entries (qwen3p6-plus) but no Qwen 3.5 entries for Fireworks.

Missing Models

Note: accounts/fireworks/models/qwen3p5-9b is also missing but limited to 3 IDs per issue.

Context

• The catalog has accounts/fireworks/models/qwen3p6-plus and several Qwen 3 variants, but no Qwen 3.5 family on Fireworks
• Exact model IDs should be verified via the Fireworks API before adding

Sources

• Fireworks AI Models — lists Qwen 3.5 models on serverless inference
