A rate is withheld below 0.5 endpoint-years of exposure. | Method | Endpoints | Endpoint-years | Changes | Rate (/endpoint-year) | 95% interval | | --- | --- | --- | --- | --- | --- | | LT | 7 | 0.54 | 0 | 0.00 | 0.00–5.51 | | B3IT | 8 | 0.48 | 4 | — | — | ## Drift by model Every endpoint ionstream serves. Each endpoint's full drift series and detected changes are in the JSON above. ## Monitoring & changes over time Endpoints under monitoring each month (the exposure the rate divides by) are in the JSON above under `months` and `variants[].monitoring`. ## Serving variants A provider's quantizations are separate serving stacks and drift separately. | Variant | Endpoints | LT rate | LT 95% interval | LT changes | B3IT endpoints | B3IT changes | | --- | --- | --- | --- | --- | --- | --- | | fp4 | 4 | — | — | 0 | 4 | 2 | | — | 2 | — | — | 0 | 2 | 2 | | fp8 | 2 | — | — | 0 | 2 | 0 | | bf16 | 1 | — | — | 0 | 0 | 0 | ## Endpoints | Model | Variant | Org | Status | Changes | Methods | Last change | | --- | --- | --- | --- | --- | --- | --- | | [deepseek-v4-pro](https://www.trackllm.net/endpoints/deepseek2fdeepseek-v4-pro23ionstream2ffp4.md) | [ionstream/fp4](https://www.trackllm.net/providers/ionstream.md) | [deepseek](https://www.trackllm.net/orgs/deepseek.md) | retired | 1 | `LT` `B3IT` | 2026-08-02 | | [deepseek-v4-pro-0813](https://www.trackllm.net/endpoints/deepseek2fdeepseek-v4-pro-081323ionstream.md) | [ionstream](https://www.trackllm.net/providers/ionstream.md) | [deepseek](https://www.trackllm.net/orgs/deepseek.md) | tracked | 1 | `LT` `B3IT` | 2026-09-29 | | [deepseek-v4.1-flash](https://www.trackllm.net/endpoints/deepseek2fdeepseek-v4.1-flash23ionstream.md) | [ionstream](https://www.trackllm.net/providers/ionstream.md) | [deepseek](https://www.trackllm.net/orgs/deepseek.md) | tracked | 1 | `LT` `B3IT` | 2026-10-10 | | [glm-5.2](https://www.trackllm.net/endpoints/z-ai2fglm-5.223ionstream2ffp4.md) | [ionstream/fp4](https://www.trackllm.net/providers/ionstream.md) | [z-ai](https://www.trackllm.net/orgs/z-ai.md) | retired | 1 | `B3IT` | 2026-07-29 | | [deepseek-v4-flash](https://www.trackllm.net/endpoints/deepseek2fdeepseek-v4-flash23ionstream2ffp4.md) | [ionstream/fp4](https://www.trackllm.net/providers/ionstream.md) | [deepseek](https://www.trackllm.net/orgs/deepseek.md) | retired | 0 | `LT` `B3IT` | — | | [deepseek-v4-flash-0731](https://www.trackllm.net/endpoints/deepseek2fdeepseek-v4-flash-073123ionstream2ffp4.md) | [ionstream/fp4](https://www.trackllm.net/providers/ionstream.md) | [deepseek](https://www.trackllm.net/orgs/deepseek.md) | retired | 0 | `B3IT` | — | | [gemma-4-26b-a4b-it](https://www.trackllm.net/endpoints/google2fgemma-4-26b-a4b-it23ionstream2fbf16.md) | [ionstream/bf16](https://www.trackllm.net/providers/ionstream.md) | [google](https://www.trackllm.net/orgs/google.md) | retired | 0 | `LT` | — | | [qwen3-coder-next](https://www.trackllm.net/endpoints/qwen2fqwen3-coder-next23ionstream2ffp8.md) | [ionstream/fp8](https://www.trackllm.net/providers/ionstream.md) | [qwen](https://www.trackllm.net/orgs/qwen.md) | retired | 0 | `LT` `B3IT` | — | | [qwen3.8-27b](https://www.trackllm.net/endpoints/qwen2fqwen3.8-27b23ionstream2ffp8.md) | [ionstream/fp8](https://www.trackllm.net/providers/ionstream.md) | [qwen](https://www.trackllm.net/orgs/qwen.md) | tracked | 0 | `LT` `B3IT` | — | ## Detected changes | Date | Endpoint | Method | Magnitude | Description | | --- | --- | --- | --- | --- | | 2026-10-10 | [deepseek-v4.1-flash @ ionstream](https://www.trackllm.net/endpoints/deepseek2fdeepseek-v4.1-flash23ionstream.md) | B3IT | TV 0.34 | Probe-prompt outputs shifted (total variation 0.34) | | 2026-09-29 | [deepseek-v4-pro-0813 @ ionstream](https://www.trackllm.net/endpoints/deepseek2fdeepseek-v4-pro-081323ionstream.md) | B3IT | TV 0.30 | Probe-prompt outputs shifted (total variation 0.30) | | 2026-08-02 | [deepseek-v4-pro @ ionstream/fp4](https://www.trackllm.net/endpoints/deepseek2fdeepseek-v4-pro23ionstream2ffp4.md) | B3IT | TV 0.30 | Probe-prompt outputs shifted (total variation 0.30) | | 2026-07-29 | [glm-5.2 @ ionstream/fp4](https://www.trackllm.net/endpoints/z-ai2fglm-5.223ionstream2ffp4.md) | B3IT | TV 0.57 | Probe-prompt outputs shifted (total variation 0.57) | --- Data collected via the OpenRouter API.
