Jul 1, 2025July 2025 (2025-07) highlights for shengxinjing/ollama: No new features shipped; however, a critical reliability fix was implemented in the API error handling. StatusError is now evaluated before general errors, eliminating an unreachable-status error path. A dedicated test was added to validate this scenario, improving test coverage and reducing risk of incorrect status propagation. The change strengthens API stability for downstream clients with minimal risk and aligns with ongoing quality objectives.

Feb 1, 2025February 2025 monthly summary for shengxinjing/ollama. The month focused on delivering business value through documentation, reliability, and performance improvements. Key features delivered and major outcomes include: - Feature: Model Interface Documentation and API Parameter Naming. Clarified the high-level model interface (model.go) by detailing Options, Base, and Model, and updated New to use a descriptive parameter name 'modelPath' to reduce onboarding time and misconfigurations. Commit: d006e1e09be4d3da3fb94ab683aa18822af4b956 ("model: document high-level model interface (#9122)"). - Feature: API Client Reliability. Added comprehensive unit tests for Client.stream and Client.do, covering invalid status codes, malformed error messages, and successful response streams to strengthen error handling and reduce incident risk. Commit: 14b5a9a150598d724e4ef17616cdb25257ddc155 ("api: document client stream behavior with a test (#8996)"). - Feature: Performance Improvement. Defaulted to a greedy sampler in the runner to mitigate performance regressions, improving throughput and latency while new sampler logic is benchmarked. Commit: 0c1041ad851d2ce3dc4d74d5fedb1af759956688 ("runner: default to greedy sampler for performance (#9407)"). Overall, these efforts contribute to a more reliable, faster, and developer-friendly Ollama experience, with clearer API usage, more robust client behavior, and tangible performance gains.
