Changelog
Notable platform and API changes. Webhook subscribers also receive billing.rate_change and model.deprecation_announced events for anything that affects pricing or availability.
- 2026-04-22added
Qwen 3.6 27B is GA
Strong on multilingual code and tool calling. Available at fp16, fp8, and int4.
- 2026-04-08changed
Default quantization for DeepSeek V4 Pro is now fp8
Calibrated evals show < 0.5% delta vs fp16 on MMLU-redux, GSM8K, and HumanEval-Plus. Throughput is up ~1.7×, per-token price unchanged. Pin fp16 explicitly if you need parity with published benchmarks.
- 2026-03-22changed
Webhook retries follow exponential backoff
Retry schedule moved from a flat 5-minute interval to: 0s, 30s, 2m, 10m, 1h, 3h, 6h, 12h, 24h. Total window is unchanged at ~24h. The Hoonify-Delivery header now increments per attempt for log correlation.
- 2026-02-26fixed
Stale Retry-After when behind some proxies
Fixed a regression where Retry-After was rounded to the nearest minute on some egress paths, causing clients to back off harder than necessary. SDKs now see fractional second values again.
- 2026-02-12deprecated
Gemma 3 27B is sunset
Hoonify is removing Gemma 3 27B on 2026-05-15. Gemma 4 31B at fp16 is the recommended replacement and is consistently ahead on capability evals at comparable throughput cost. The API returns a deprecation field; webhook event model.deprecation_announced has fired.
- 2026-02-04security
API key prefix
New key format: hoon_sk_live_. Existing keys stay valid until 2026-08-01. Rotate at your own pace via the API keys page.
- 2026-01-20added
system_fingerprint in response body
Every chat completion now returns a system_fingerprint. Stable while the operator setup, model, and quantization are unchanged — useful for caching and reproducibility.
