Run local text-generation models for secure, low-latency inference
Ollama is a developer-focused local model runtime and repository for running open and commercial LLMs on your machine or private infrastructure; it serves engineers, researchers, and privacy-conscious teams who need offline or on-prem inference, and its core offering includes a free tier and paid team/enterprise options for larger scale and cloud-hosted management.
Ollama is a local-first text generation platform that lets developers run, host, and share LLMs on their own machines or private servers. It provides a CLI, desktop app, and API-like HTTP endpoints to load model images, run inference, and manage prompts — the primary capability is private, low-latency text generation without sending data to third-party cloud inference. Its key differentiator is local model hosting with simple image-based model distribution and sandboxed containers that support both open models and licensed images. Pricing starts with a free local-use tier and paid Team and Enterprise plans for cloud hosting, private registries, and centralized management.
Ollama launched as a local-first LLM runtime that positions itself between running raw model binaries and using closed cloud APIs. Built by a small team focused on local ML tooling, Ollama's core value proposition is to give developers and organizations the ability to run generative text models on their own hardware while keeping a simple developer experience: pull a model image, run a container-like runtime, and query the model over a localhost HTTP endpoint. This approach targets privacy-conscious users who need reproducible environments and control over model binaries, avoiding mandatory cloud data transfer and vendor lock-in.
The product ships several concrete capabilities. First, the Ollama runtime supports model images that you pull with ollama pull and run with ollama serve, exposing a REST-style API on localhost; this lets you integrate models in apps as if you were calling an external API. Second, it provides a model registry and image format that can host community and licensed models; Ollama distributes curated images (including open models like Llama 2 derivatives) and supports loading custom model directories. Third, the platform offers prompt and usage tooling: you can save named prompts, run batch prompt files, and manage tokenization and generation parameters (temperature, top_p, max_tokens) via the CLI or the desktop app. Fourth, Ollama includes developer ergonomics like a local chat UI, history, and extensibility hooks for embedding in pipelines and CI.
Ollama's pricing mixes a free local tier with paid cloud/managed offerings. The free tier allows running the Ollama runtime locally on your own hardware for personal or development use with no per-request fees; there are limits inherent to your hardware (GPU/CPU and memory) rather than enforced API quotas. Paid offerings include Team plans and Enterprise options for hosted model registries, centralized billing, private model image hosting, and remote-managed instances. As of the latest available information, detailed public per-seat prices for Team/Enterprise are provided upon inquiry on Ollama's site or sales process — Ollama documents free local use but routes commercial hosting and SSO/enterprise features to paid contracts.
Ollama is used by developers, ML engineers, and product teams for private inference, model evaluation, and prototype deployment. Example workflows include a Backend Engineer using Ollama to run a Llama 2-based assistant on on-prem GPUs for a customer-facing chatbot with <100ms local latency, and an ML Researcher using Ollama to evaluate model behavior by swapping model images and measuring output differences across versions. Companies evaluating Ollama often compare it to hosted API providers like OpenAI for cloud convenience; Ollama wins where local control, licensing compliance, or offline deployment are required, while cloud services still dominate for scale and managed elasticity.
Three capabilities that set Ollama apart from its nearest competitors.
Current tiers and what you get at each price point. Verified against the vendor's pricing page.
| Plan | Price | What you get | Best for |
|---|---|---|---|
| Free | Free | Local runtime only; limited to your machine’s CPU/GPU and no hosted registry | Individual developers and local experimentation |
| Team | Contact sales | Hosted model registry, team management, remote instance provisioning (custom quotas) | Small teams needing shared models and cloud hosting |
| Enterprise | Custom | SAML/SSO, private image registries, enterprise support and SLAs | Organizations requiring on-prem/managed deployments and compliance |
Copy these into Ollama as-is. Each targets a different high-value workflow.
You are a technical writer creating concise API error payloads for an Ollama-powered inference service. Constraints: produce 6 distinct errors; each object must include numeric code, HTTP status, short message (<=90 chars), and one-line actionable suggestion; avoid implementation details or stack traces. Output format: a JSON array of 6 objects: {"code":int,"http_status":int,"message":string,"suggestion":string}. Example item: {"code":1001,"http_status":429,"message":"Rate limit exceeded","suggestion":"Retry after 10s or request a higher quota"}. Provide exactly 6 objects, no extra text.
You are a developer documenting a minimal quickstart README snippet for running an Ollama model locally. Constraints: 4 numbered steps, include exact commands, required env vars, default ports, and a one-line verification command; keep each step one sentence; total length under 12 lines. Output format: Markdown ready to paste into a repository README. Example step: "1. Install Ollama CLI: curl -fsSL https://ollama.ai/install | sh". Provide no additional explanation beyond the 4 steps and a one-line verification example.
You are a DevOps engineer authoring a Kubernetes Deployment and Service YAML for hosting an Ollama model image. Constraints: include placeholders for image name and tag, CPU/memory requests and limits, a Secret volume mount for private registry credentials, liveness and readiness probes (HTTP or TCP), and Node selector label 'ollama=true'; target a single replica. Output format: a single multi-document YAML (Deployment + Service) with clear {{PLACEHOLDER}} fields and comments where secrets or env vars are required. Do not include extra explanation.
You are a backend engineer creating a benchmark harness to compare Ollama model images. Constraints: accept a list of model image names and iterations as CLI args, measure p50/p90/p99 latency and peak RSS memory per model, run N requests of a fixed payload, sleep 500ms between requests, and output CSV with columns: model,iteration,p50_ms,p90_ms,p99_ms,peak_rss_mb. Output format: a single Bash or Python script (choose one) ready to run on Linux with curl and /proc or psutils for memory; include usage comment at top. Do not add extra commentary.
You are an ML researcher analyzing and scoring two model images' outputs on the same prompt. Role: analytic reviewer. Given two example pairs below, produce: (1) a concise comparative summary (3 bullets) highlighting strengths/weaknesses; (2) quantitative scores for relevance, factuality, conciseness (0-5) with brief justification; (3) 3 labeled error annotations per model with timestamps or tokens; (4) two rewritten prompts to improve factuality. Examples (use these as few-shot style): Example A input: "Summarize climate policy"; Model X output: "...incorrect 2030 target..."; Model Y output: "...mentions Paris Agreement". Example B input: "Explain Docker volumes"; Model X output: "...mixes up bind mount and volume"; Model Y output: "...correct but verbose". Now analyze for new input: "Describe Ollama model deployment best practices." Follow same deliverable structure. Output format: JSON object with fields summary,scores,annotations,rewrites.
You are a senior DevOps/security engineer designing a GitHub Actions workflow to build, scan, sign, and push an Ollama model image to a private registry. Constraints: include steps for checkout, build image from model directory, run a container image scanner (e.g., trivy) failing on high CVEs, sign the image artifact with cosign using a repository secret, push to a private registry using a secret-based login, and a rollback step that deletes the pushed tag on failure; use environment variables for IMAGE_NAME and TAG. Output format: a complete .github/workflows/ci.yml GitHub Actions YAML with placeholders for secrets and brief in-line comments for each step. No external explanation.
