# pi-synthetic: v0.24.0

release · 2026-07-28 · #pi-synthetic · v0.24.0

### Minor Changes

- 650b4c1: Apply Synthetic's 80% cache-read discount in the model catalog instead of the streamSimple wrapper. The wrapper is removed and Pi's built-in cost calculation now uses the discounted `cacheRead` rate directly.
- a6f10fa: Add Kimi-K3, drop Kimi-K2.7-Code, and store cache-read price as reported by the API.

  - Add `hf:moonshotai/Kimi-K3` (text+image, 524k context). Verified reasoning
    behavior via the Synthetic connector: backend accepts `none`/`low`/`high`/
    `max`, rejects `medium`; `low` emits no reasoning content. thinkingLevelMap
    exposes off/high/max.
  - Remove `hf:moonshotai/Kimi-K2.7-Code` (no longer in the Synthetic catalog).
  - Update `syn:large:vision` to its current backing model pricing/context
    (524k context, $3/$15) and the Kimi-K3 reasoning map.
  - Remove the automatic cache-read discount. The catalog and API-sourced
    models now store the `input_cache_reads` price as reported by the Synthetic
    API directly, with no 80% discount applied in code. `syn:large:text` and
    `hf:zai-org/GLM-5.2` cacheRead updated from 0.2 to 0.16 to match the API.
    Verified against live billing: cache-read calls are charged at the API's
    `input_cache_reads` rate (e.g. $0.45/M for Kimi-K3), cache writes are free.
  - Add a thinkingLevelMap to `hf:openai/gpt-oss-120b`. Probed all efforts:
    the backend accepts `none`/`minimal`/`low`/`medium`/`high`/`xhigh` and
    rejects `max` (400). The model reasons at every accepted effort including
    `none`, so reasoning cannot be disabled (`off` hidden). Exposes
    minimal/low/medium/high/xhigh; hides `max` to avoid a 400 on the top level.

### Patch Changes

- 496de92: Update GLM-5.2 pricing in the hardcoded fallback catalog to match the Synthetic API: input and cache-read drop from $1.40 to $1.00 per million tokens, output drops from $4.40 to $3.00 per million tokens.
