Together GPU Clusters scores 58.1 (C) on agent readiness against Vast.ai's 56.4 (C), and leads in 2 of 7 scored categories. Vast.ai leads on reliability and maintenance & community. Both do gpu compute.

- Together GPU Clusters: C 58.1, rank #768 of 1510 · https://www.anchorterminal.com/tools/together-gpu-clusters.min.md
- Vast.ai: C 56.4, rank #829 of 1510 · https://www.anchorterminal.com/tools/vast-ai.min.md
- Together GPU Clusters, good for Training, fine-tuning and batch jobs that need several 8-GPU nodes with InfiniBand, run by a pipeline that creates and deletes clusters. Ahead on Schema & documentation, 92 against 78. Also No incidents deducted, where Vast.ai loses 3 points for them.
- Vast.ai, good for Cost-sensitive training, batch work and self-managed inference where the agent can search listings, set a price cap and tolerate host variance or interruption. Ahead on Reliability, 50 against 38; Maintenance & community, 81 against 75.

Why the edge:
- Schema & documentation, Together GPU Clusters +14: Together GPU Clusters 92 (Public OpenAPI 3.1 for /v1/compute/clusters and shared volumes, MIT, embedded in every reference page (25). llms.txt and a Markdown twin of every page (10). The docs say when to choose Kubernetes or Slurm and each capacity type, and the management page carries instructions for agents on reporting live availability and prices (18). Enums for cluster type, billing type, GPU type and status, required fields marked (13). CLI, Python, TypeScript and console steps on each task, with 402 and 403 cases documented, though no error catalogue for the clusters API (11). Versioned SDKs and a dated changelog with cluster entries (15). 25+10+18+13+11+15 = 92.); Vast.ai 78 (Public OpenAPI 3.1 file with 66 paths and 89 operations, re-read on 2 November, plus the YAML source in the CLI repository (25). llms.txt on both vast.ai and docs.vast.ai, with every docs page served as Markdown (10). Operation descriptions give the matching CLI command and rules such as template precedence, and the SKILL.md files list quirks and common errors, though the API introduction steers most users to the CLI (15 of 20). Request bodies are typed, with 37 enums and required fields marked. Search filters are operator objects and several routes are not REST-shaped, such as PUT /asks/{id}/ to create an instance (10 of 15). Examples on most operations and 400, 401 and 429 responses on most, but the docs say the error body varies by endpoint (11 of 15). Routes are versioned v0 and v1 and the CLI has tagged releases. No API changelog was found in the docs index (7 of 15). 25 + 10 + 15 + 10 + 11 + 7 = 78.)
- Reliability, Vast.ai +12: Together GPU Clusters 38 (Read with the hosted lines. status.together.ai lists the website, the playground and serverless models with no component for GPU clusters, and a vendor page with no component for the product takes 15 in this run, as for Together's Code Sandbox and fine-tuning listings (15). No incident history for clusters can be read (5). No rate limits for the clusters API found (0). Together's docs give 429 and 503 backoff guidance for its APIs, per the inference listing's 1 November check, and the CLI has `--non-interactive` and `--json` for scripted retries, but creation has no idempotency key (8). No SLA for clusters found; the published 99% commitment covers provisioned inference throughput only (0). Generally available since 9 September 2025 and out of the CLI's beta paths since 22 October 2026, with preemptible nodes in preview (10). 15+5+0+8+0+10 = 38.); Vast.ai 50 (Graded as a hosted service. status.vast.ai is Vast.ai's own page with three components (vast, console, serverless) and 30-day bars built from roughly hourly checks, with no incident write-ups (20). The page draws its bars by script from check-log files on the same host. The 8 October count came from those files, the page's own data, which this run doesn't read (as the Docusign and SeaTable listings read their status pages' data feeds), so it's struck, and the window from 4 August to 2 November is unread (5). The page covers Vast.ai's control plane and not the independent hosts' machines. Rate limits are described as a minimum interval per endpoint and identity, re-read on 2 November, but thresholds are unpublished apart from an `x-rateLimit` value on 2 of 89 operations in the OpenAPI file (5 of 15). 429 is documented with backoff advice and the CLI retries it, but the docs say the API sets no `Retry-After` header, and there is no idempotency key for instance creation (10 of 15). No SLA found, and the terms say availability is not guaranteed (0). Instances, serverless and the REST API carry no beta label (10). 20 + 5 + 5 + 10 + 0 + 10 = 50.)
- Maintenance & community, Vast.ai +6: Together GPU Clusters 75 (Closed service. The newest cluster change is CLI and SDK 3.0 on 22 October 2026, 15 days before this check (30). Dated cluster entries in the 90 days from 8 August include 12, 18, 19, 24, 27 and 28 August, 10 September and 22 October (20). Dated changelog, a support portal and Discord, with responsiveness not tested (8). Python SDK 3.1 and TypeScript SDK 1.0 are current and cover clusters (15). SDK CI and dependencies weren't audited (2). 30+20+8+15+2 = 75.); Vast.ai 81 (`vastai` v1.10.0 was tagged on 30 October 2026 by the repository's publish workflow (30). Thirteen tagged releases between 4 August and 2 November 2026, from v1.5.3 (10 August) to v1.10.0 (30 October) (20). Per the 8 October check, not re-read on 2 November (GitHub's API refuses this session), the repository had 54 open issues and pull requests, 22 of the 30 most recently opened without comments. Vast.ai lists 24/7 chat support and Discord, which we did not test (10 of 25). The CLI and Python SDK are current and ship together. The Claude Code, Codex and Cursor plugins were last changed in June 2026 (15). Three CI workflows cover the installer, publishing and SDK tests. An open issue of 6 September 2026 reports hard-pinned dependencies, and we did not check whether CI passes (6 of 10). 30 + 20 + 10 + 15 + 6 = 81.)
