Ollama vs PrivateGPT

Ollama 81

v0.40.14, tagged on 2 November 2026 and pinned to llama.cpp b11963 (30). 35 stable releases in the 90 days from 6 August, v0.32.7 (9 August) to v0.40.14, plus release candidates, which a default install doesn't get (20). Open issues and reply times per the 3 October check (2.5k open issues and 1.5k open pull requests, recent reports without a reply we could see), not re-read; 158 commits from v0.35.1 to v0.40.14, 113 citing a pull request number (10 of 25). Official Python (v0.6.3) and JavaScript (v0.6.4) libraries, both tagged on 28 September 2026, the newest tags on 4 November (15). Go 1.26.10 and CUDA and ROCm builds in the release workflow, CI only on pull requests and no Dependabot configuration (6 of 10). 30 + 20 + 10 + 15 + 6 = 81.

PrivateGPT 41

The last release is 1.0.1, dated 16 June 2026 in the changelog and tagged 18 June, 141 days before the check (10 of 30). No release or dated changelog entry in the 90 days since 8 August (0 of 20). Maintainers commit most days and outside pull requests merged in October, but 23 pull requests are open and the stale bot closes issues, including two security reports, with no maintainer reply (13 of 25). Homebrew tap, wheel index and Docker images ship with releases, and Anthropic SDKs work against it. No product MCP server of its own, though it connects to remote MCP servers (10 of 15). Dependabot, uv.lock, actions pinned by commit since 19 October and dependency CVE upgrades in June, July and August (8 of 10). 10 + 0 + 13 + 10 + 8 = 41.

Ollama 53

Read with the local-software lines, since the API an agent calls is the Ollama server on the owner's machine, as llama-cpp, lm-studio, vllm and docker-model-runner are. Ollama Cloud has no status page we could reach (status.ollama.com didn't resolve on 3 October), and we graded the local server. Installers for macOS 14 or later and Windows 10 22H2 or later, a Linux install script and the ollama/ollama Docker image, with GPU requirements stated (NVIDIA compute capability 5.0 and driver 550 or newer, ROCm, Vulkan, Metal and MLX) (20). The test workflow runs Go tests and builds on pull requests only (test.yaml at v0.40.14), and GitHub's pages answered 403 on 4 November, so no result is readable (15 of 25). Open issues and pull requests per the 3 October check (2.5k and 1.5k, recent regressions without a reply we could see), not re-read (9 of 25). Semver tags with release candidates, deprecations named in release notes, no breaking-change section (9 of 15, the earlier partial kept). Version 0.40.14, pre-1.0 (0). 20 + 15 + 9 + 9 + 0 = 53.

PrivateGPT 70

Read with the local-software lines, since PrivateGPT runs on the owner's hardware with no hosted service behind it. Homebrew tap, uv tool install from Zylon's own wheel index (not PyPI) and Docker Hub images zylonai/private-gpt 1.0.1 of 18 June 2026. Python 3.11 only, stated in pyproject.toml, and it needs a separate OpenAI-compatible model server (17 of 20). tests.yml runs format, lint, typecheck and the tests affected by each push on main, with the full suite of 217 test files on release pull requests. We couldn't see run results because the GitHub API refused us, and issue #2441 of 1 November reports the Claude spec update workflow failing (15 of 25). GitHub shows 3 open issues of about 1,250, because a stale bot closes quiet issues, two security reports among them, with no maintainer reply (12 of 25). release-please keeps a changelog with breaking changes marked, but no release has been cut since 1.0.1 while main carries 51 commits since 8 August, among them a breaking observability change of 23 October (11 of 15). Version 1.0.1 (15). 17 + 15 + 12 + 11 + 15 = 70.

Ollama 75

Read for an API. Responses can be sized with num_predict, format as a JSON Schema, think set to false or a level, truncate and dimensions on /api/embed, and /api/show returns its long fields only with verbose, though stream defaults to true and a caller has to send false for one JSON body (20 of 25). Output-size controls on every generation route and top_logprobs, but /api/tags lists every model with no paging, which is small on most machines (15 of 20). Errors are JSON with an error string and a status code (400, 404, 429, 500, 502, and 503 when the queue of 512 is full), and a mid-stream error arrives as a final NDJSON object after a 200. There's no error code beyond the message (13 of 20). Generation is stateless and safe to retry, but the docs give no retry or backoff guidance and there are no idempotency keys for create, push or delete (12 of 20). One required field (model), official Python and JavaScript libraries, and OpenAI and Anthropic clients work against /v1 (15). Per the 3 October reading of the docs, which are unchanged in kind at v0.40.14 in the repository.

PrivateGPT 64

Read for an HTTP API an agent calls on a local instance. Token counting, top_k style retrieval settings, citation output and response byte caps let a caller size context (18 of 25). Artifact listing by namespace and retrieval filters, with no documented cursor pagination (12 of 20). FastAPI validation errors name the field and the validate route checks a request before running it, but there is no error catalogue (12 of 20). Async messages and ingestion return task ids with status, cancel and delete routes. No idempotency keys were found (10 of 20). Anthropic SDKs and Claude Code work by pointing ANTHROPIC_BASE_URL at the server, but a model server and an embedding server have to be configured first (12 of 15). 18 + 12 + 12 + 10 + 12 = 64.
