Vellum
Pros
- + Memory is inspectable and persistent: by day four it applied preferences I set once, and I could see and correct confidence-scored extractions
- + The permission system asked before emailing new contacts or touching protected files, then stayed out of the way on trusted work
- + Transparent billing: credits are provider cost with no markup — my two weeks of heavy use consumed about $18 in credits
- + Self-hosting the open-source build on your own keys drops the $50/month hosting layer to zero
- + Multi-channel continuity across Mac, iOS, web, Telegram, Slack and email with one identity and task list
Cons
- - The LLM development platform this listing describes is gone — no prompt management, evaluation or workflow product remains at vellum.ai
- - The $50/month Pro price is hosting only and includes zero AI usage; real cost lands near $90/month all-in for a heavy user
- - A full pivot from a small company is a real continuity risk for anyone who commits workflows to it
- - MCP server setup is CLI-level work and connector quality varies across the skills catalog
- - No enterprise SLA, SSO or team administration layer comparable to corporate-grade tooling
Ollama
Pros
- + Local inference is free and unlimited — cost is hardware and electricity, and prompts never leave the machine (OLLAMA_NO_CLOUD=1 disables the cloud path entirely)
- + OpenAI- and Anthropic-compatible endpoints at localhost:11434 meant existing SDK code worked for me after a single base_url change, including JSON-schema structured output
- + Install-to-first-chat took about two minutes on my M-series Mac with a quantized 8B model, and ollama ps shows the GPU/CPU split honestly
- + Huge ecosystem: ~183k GitHub stars, setup docs for 20+ agents and editors, official Python and JS libraries
- + v0.40.x MLX default made prompt processing measurably faster on Apple Silicon in my runs, and releases ship every few days
Cons
- - Memory-tiered default context window truncates long inputs out of the box — I had to raise num_ctx explicitly in a coding-agent setup
- - Quality ceiling is your hardware: a local 7B quant visibly trails frontier hosted models on hard reasoning
- - No end-user polish — quantization, context sizing, and memory management stay your problem, and CPU-only machines run slowly
- - Fast release cadence creates churn for pinned deployments (e.g. v0.34.1 moved GGUF creation out to llama.cpp tooling)
- - Cloud Team plan pricing conflicts across sources ($500/mo flat vs $25/seat with 5-seat minimum); Max signups reported paused at times
