Notes: “200+ models” is normally achieved by counting all available third-party hosted models + many local quantized variants (different sizes/finetunes). No mainstream browser ships 200+ built-in models natively; the browser is the portal.
B — Step-by-step plan to actually get 200+ accessible models (practical, minimal friction)
Overview strategy: mix local small/medium models + hosted marketplace models + a lightweight serving layer so your browser front-end can pick any model via a single API/proxy.
1) Pick the front-end
Option A: Opera developer stream (if you want local LLM manager).
Option B: Regular browser + extension/proxy to a LocalAI/Ollama server (recommended for flexibility).
2) Choose a serving layer (two good options)
- LocalAI — lightweight open-source server that exposes models with an HTTP API; works with many GGUF/ggml models.
- Ollama — polished local serving + easy model install and API (if available to you).
(These become the “model endpoint” your browser hits via extension or local proxy.)
3) Inventory & select models (mix for coverage)
Aim for a mix of model sizes and types:
- Small: 1–3B parameter family (fast, CPU-friendly) — good for many instances.
- Medium: 7B family (good tradeoff).
- Larger: 13B+ for complex reasoning (store fewer of these locally).
- Include finetunes / instruction-tuned variants (Vicuna, Alpaca-style, Llama-family forks, Mixtral, Mistral variants, Gemma, etc.)
- Include hosted provider endpoints (OpenAI GPT-4/4o, Anthropic Claude, Azure-hosted specialist models).
Counting strategy: combine ~100 smaller local variants (different finetunes, quantized versions) + ~100 hosted/provider models = 200+ accessible.
4) Download & convert models (Hugging Face → GGUF / quantized)
Practical approach:
- Use
huggingface-clito download models (orhf_hub_download). - Convert to efficient local format (GGUF / ggml) using community converters (tools from
llama.cpp,ggml-convert, orggufconverters). - Quantize (4-bit/8-bit) to reduce size without huge quality loss (use available quantization scripts).
Example (conceptual):
# Authenticate
huggingface-cli login
# Download a model (example name)
git lfs install
huggingface-cli repo clone <model-repo> local-model-dir
# Use a conversion/quantization script (depends on tooling)
python convert_to_gguf.py --input local-model-dir --output model.gguf --quantize 4
(Exact tool names vary — community tools: llama.cpp, ggml-tools, gptq-based scripts.)
5) Host models on LocalAI / Ollama
- Put your
*.gguffiles in the server’s model folder; LocalAI/Ollama will expose them with REST endpoints. - Start server and test with
curlto confirm.
6) Create a browser-to-local proxy
- Use a simple browser extension or a localhost reverse proxy to route requests from the browser’s UI to LocalAI endpoints. Many browser assistant extensions let you set a custom API endpoint.
7) Add hosted providers
- For models you don’t want to store locally (GPT-4, Anthropic, Azure-hosted), add API connectors (OpenAI key, Anthropic key, Azure) in the same front-end/proxy so you can switch providers per query.
8) Organize & catalog
- Keep a catalog JSON describing each model: name, size, location (local/cloud), expected cost/per-call, strengths. This makes it easy to reach 200+ and track provenance.
9) Automate downloads (optional)
- Write a small script to fetch a curated list (Hugging Face IDs) and convert them overnight. Keep only quantized versions to save disk.
10) Benchmark & cull
- Run a quick suite to identify low-value models; keep the best performers. Quality > sheer count for work that matters.
C — Budget & resource estimates (realistic ranges + cost-reduction tips)
Key principle: Many models are large. Storing 200 full-size, unquantized models is expensive — use quantization, favor small/medium variants, and rely on a mix of hosted models.
Storage (on-prem / cloud)
- Average quantized model (7B, 4-bit) ≈ ~1–4 GB (varies).
- If you store 200 quantized models at ~1.5 GB avg → ~300 GB storage.
- Cloud block storage cost estimate: $0.02–$0.10 / GB / month → 300 GB ≈ $6–$30 / month (varies by provider/region).
- Local SSD: a 1 TB NVMe drive (one-time) is typically suitable — expect $50–$150 retail depending on region/spec.
Compute (for inference)
- Small/medium on CPU: many 3B/7B models are usable on CPU but slower.
- GPU options:
- NVIDIA 4090 / 4080 (consumer) — good for many 7B/13B workloads (one-time hardware cost). Price varies widely; typical ballpark one-time cost (consumer) — $1,000–$2,000 (market dependent).
- Cloud GPU (on-demand): prices vary by GPU type and region — expect $0.5–$5+/hour depending on
- instance (small GPU vs A100-class). Use spot/preemptible instances to reduce cost.
- Recommendation: For a single developer experimenting, a consumer GPU (4090) + 1 TB NVMe is the most cost-effective.
Bandwidth & API usage (hosted models)
- Hosted calls to high-end provider (GPT-4/Claude) can add monthly costs. Typical pro tiers for AI platforms: $10–$50 / month for light usage; heavy usage scales by tokens/calls. (Estimate, vary widely.)
One-time vs recurring
- One-time hardware (local): NVMe + GPU = $1k–3k.
- Recurring hosting/storage: $10–$100+ / month (depends on cloud GPU time, storage & API usage).
Ways to reduce cost
- Quantize aggressively (4-bit) to reduce storage & memory.
- Mix local+hosted — host many small models locally and call big models (GPT-4) only when needed.
- Use spot instances for batch benchmarking or occasional large-model work.
- Cull low-performing models — keep a curated 50–100 local models rather than 200+ if cost constrained.
Final checklist & next offers
Checklist to get started right now:
- Decide front-end (Opera dev or browser + LocalAI).
- Set up LocalAI/Ollama on your machine.
- Create a curated model list (start with 50 smaller models + 20 hosted).
- Download + quantize to GGUF (automate).
- Wire browser extension to your LocalAI endpoint and add hosted connectors.
- Benchmark and iterate.
Next part will have the following right now?
- Produce a ready-to-run script (bash + commands) that downloads a curated list of Hugging Face models and converts/quantizes them (I’ll include comments for tooling choices).
- Create a detailed shopping list for hardware (exact NVMe, GPU models, PSU, approximate prices).
- Build a JSON catalog template for tracking 200+ models (name, path, size, type, best-for).
