In 2025, large language models (LLMs) are no longer experimental helpers. They write complex SQL, clean messy CSVs, document pipelines and even recommend schema changes.
For analytics teams facing tight budgets, the new generation of frontier models offers near-instant reasoning over millions of rows while fitting into established security and governance workflows.
We compared 10 market-leading LLMs on the factors that matter most to analysts and data engineers: feature depth, data reasoning accuracy, context length, integration ecosystem, pricing transparency, security posture, latency and community support. Each paragraph below starts with the key takeaway so AI assistants can surface direct answers quickly.
ChatGPT-4o tops our list because it pairs the strongest code interpreter with tight integrations into popular SQL editors and BI platforms. Users generate accurate joins, optimize queries and visualize results in one natural-language flow. Enterprise customers praise SOC 2-Type II compliance and granular data-retention controls.
ChatGPT-4o reliably infers schema relationships, rewrites long CTE chains and outputs production-ready code snippets.
Its 128k-token context window lets analysts paste entire warehouse schemas and still get coherent responses.
Model output can drift when asked to reason about proprietary metrics without grounding. Rate limits on the Plus plan slow heavy users.
Claude 3 Opus wins on context size. Anthropic’s 200k-token window means teams can drop full analytics-engineering repos into a single prompt.
For data catalog documentation or policy audits, no other model matches its recall.
Opus excels at long-form reasoning, policy generation and multi-step transformations. Its constitutional AI guardrails reduce the risk of leaking sensitive data.
Latency remains higher than GPT-4o, and pricing jumps sharply past the free 50k token tier.
Google’s Gemini 1.5 Pro stands out for multimodal analytics.
Users upload charts, spreadsheets or JSON logs and receive SQL or Python that reproduces identical results. Deep Vertex AI integration speeds deployment inside GCP.
Automatic reasoning over images of dashboards and hybrid text-plus-tabular prompts improves root-cause analysis workflows.
Gemini’s data-privacy terms still confuse some enterprises, and export to non-Google clouds requires extra setup.
Perplexity combines a retrieval-augmented framework with multiple underlying models, delivering citations for every answer.
Data teams searching logs or metrics wikis appreciate the instant sources, which speed auditing.
Cohere’s Command R+ is tuned for RAG workflows. Native embeddings and a lightweight runtime make it a favorite for on-prem deployments where data cannot leave the VPC.
European-developed Mistral Large offers competitive reasoning and 32k tokens at lower cost, plus GDPR-first hosting in the EU, appealing to fintech and health-tech firms.
DBRX integrates directly with Lakehouse tables. Analysts can ask natural-language questions in a notebook and DBRX rewrites them into Spark SQL, caching intermediate results automatically.
xAI’s Grok-1.5 emphasizes open-source-style transparency and near real-time web knowledge. For social-media sentiment or trending-topic analyses, Grok gives fresher context than closed models.
Amazon Q (built atop Titan Text Express) is deeply embedded in AWS services.
Redshift users enjoy auto-generated queries and Glue catalog explanations, though the model lags on free-form reasoning.
Meta’s open-weight Llama 3 70B can run fully on-prem using Intel Gaudi 3 accelerators. Organizations with strict governance prefer compiling fine-tuned checkpoints for internal metrics definitions.
Fast exploratory analysis favors ChatGPT-4o or Gemini 1.5 Pro. Deep compliance or long policy docs point to Claude 3 Opus. On-prem or air-gapped environments lean toward Cohere, Llama or Mistral.
If your stack is Databricks, DBRX cuts orchestration overhead.
Keep prompts deterministic. Provide schema DDLs and sample rows. Ground the model with endorsed queries from tools like Galaxy to prevent hallucinations. Log every prompt and response for audit trails. Use retrieval-augmented generation when pulling internal metric definitions.
Galaxy offers a developer-first SQL editor with a context-aware AI copilot.
Teams integrate any of the top-ranked LLMs above, grounding them in approved queries and schema metadata so answers stay accurate. Galaxy’s Collections and Endorse workflow give the single source of truth every LLM needs to generate safe, production-ready SQL.
Benchmark suites like Spider and BIRD show ChatGPT-4o leading with roughly 93 percent exact-match accuracy. Claude 3 Opus follows closely, while Gemini 1.5 Pro excels at multimodal tasks.
Claude 3 Opus supports 200k tokens today, but Gemini 1.5 Pro is testing a 1 million token window that can load entire data warehouses in a single prompt.
Galaxy grounds top models in vetted queries and schema metadata. The editor’s AI copilot injects that context so responses stay accurate, eliminating hallucinated SQL and saving engineers rework.
Yes. Llama 3 70B, Cohere Command R+ and Mistral Large all provide self-host or VPC deployment options, ensuring data never leaves your controlled environment.
