LLaVA 1.6 34B

Cost & access

LLaVA 1.6 34B weights are available under Proprietary. Direct API cost may be $0 if you self-host; budget for GPUs, storage, and engineering instead. Hosted endpoints (Together, Fireworks, Groq, etc.) charge per token—shop providers for llava-1-6-34b latency and region. With a 128K tokens context window, long PDFs or chat histories increase input tokens quickly—trim history or summarize older turns in production.

Functional understanding

• Popular open vision assistant.
• Modalities: text, image · License: Proprietary · Released 2024-02-01.
• Best-fit workflows for this model:
• • Document OCR, chart/diagram understanding, and visual QA over screenshots or PDFs.
• • On-prem or VPC deployment when data cannot leave your network.

Technical foundation

• Community reports Undisclosed parameters; training data: Undisclosed.
• Context: 128K tokens. Open weights: yes.
• LLaVA 1.6 34B is positioned as a vision model in the Community lineup.

First API call

Run LLaVA 1.6 34B locally with Ollama or Hugging Face transformers (weights under Proprietary).

# Ollama (if model is published there)
# ollama run llava-1-6-34b

# Or Hugging Face transformers:
from transformers import pipeline

pipe = pipeline("text-generation", model="llava-1-6-34b", device_map="auto")
print(pipe("Hello from LLaVA 1.6 34B", max_new_tokens=80)[0]["generated_text"])

Important technical topics

• Prompting LLaVA 1.6 34B: be explicit about output format. Weak: "Analyze this." Better: "Return JSON with fields id, total, date for Community billing data."
• Temperature: use 0–0.3 for extraction and compliance on LLaVA 1.6 34B; 0.7–1.0 for brainstorming.
• Tokens: LLaVA 1.6 34B bills by tokens (~¾ word each). Undisclosed parameters affect capability; your bill is driven by context length and call volume.
• Context window (128K tokens): everything in one request—system prompt, tools, RAG chunks, and history—must fit. Truncate or summarize when approaching the limit for LLaVA 1.6 34B.
• Vision tokens: images in LLaVA 1.6 34B consume extra tokens (often tiled patches)—compress resolution when cost matters.

Real enterprise patterns

• Pipeline: OCR/layout → LLaVA 1.6 34B for field extraction → rules engine for validation.
• Store original images; log model version per request for audit.
• Redact PII in images before sending to third-party APIs unless self-hosting.
• Fallback to smaller vision model for simple yes/no checks.

Production & security

• Secrets: never commit keys for LLaVA 1.6 34B; use vault + per-environment rotation.
• PII: mask before inference; log redacted prompts only.
• Observability: trace id per request; log model=llava-1-6-34b, tokens in/out, latency.
• GPU monitoring: VRAM, batch queue depth, and model revision hash on each deploy.
• Guardrails: schema-validate JSON; block disallowed topics; cross-check numbers against source docs.

Mini projects with this model

• Invoice OCR: LLaVA 1.6 34B extracts line items → CSV.
• UI regression: compare screenshots, describe visual diffs.
• Safety checklist: verify PPE in warehouse photos.
• Catalog enrichment: generate alt text from product images.
