DeepInfra
Pros
- + Per-token pricing sits at the market floor: DeepSeek-V4-Flash-0731 at $0.06/M input and $0.18/M output at time of writing (deepinfra.com/pricing)
- + Cached-input discounts halve prompt-heavy costs automatically — DeepSeek V3.2 served cached prefixes at $0.13/M versus $0.26/M standard in my runs
- + Batch endpoint takes 1,000 requests per call at 50% off with 24-hour delivery, which I found ideal for classification and evaluation sweeps
- + Migration is a base-URL swap: my existing OpenAI client called DeepSeek-V3.2 on the first attempt with no adapter code
- + Financially credible for a budget provider: $107M Series B in May 2026 with NVIDIA and Samsung Next participating
Cons
- - Rate limits are enforced but not published; the 200-concurrent-request ceiling surfaced in third-party trackers, not vendor docs
- - Onboarding credit reporting conflicts across sources ($1, $5, or none) and the vendor pricing page does not settle it
- - No published SLA or managed routing on the serverless tier — model deprecations and repricing are your problem to absorb
- - Output pricing at the top of the catalog is steep (Kimi-K3 at $14.25/M output), so uncapped generation gets expensive fast
- - Catalog is overwhelmingly open-weight models; teams needing proprietary frontier models still need a second provider
OpenAI API
Pros
- + Lowest false-call rate on my 250-case tool-use evaluation, including the deliberate no-call cases
- + Single account covers text, reasoning, image, audio, transcription, embeddings and agent tooling
- + Framework integrations were config-only where rival providers needed adapter code I had to maintain
- + Official pricing page documents wrinkles (residency uplifts, Fast mode rename) that others bury
- + Streaming response times were consistent enough over a week of monitoring that I stopped tracking them
Cons
- - Tool metering ($10/1k search calls, $2.50/1k tool calls) became about a fifth of my search-heavy prototype's bill
- - Entry rate limits are tight; my batch job triggered a 429 burst until spend tier rose
- - 10% uplift on regional data-residency and FedRAMP endpoints adds to an already premium price list
- - Specialised model lines (Rosalind trusted-access, cyber tier) assume institutional buyers
- - Catalogue churn makes third-party tutorials stale within months
